Main Keywords: bridge construction quality problems; project management; municipal road bridges
Since the beginning of the 21st century, my country’s urbanization has continued to develop. And domestic large-scale engineering projects are quietly emerging. Which also put forward higher requirements for project management. To better promote the improvement of urban infrastructure. It is necessary to control the quality of engineering construction and to combine the specific national conditions of our country. Proceed from reality, put forward new management methods, and build a new technology control system realistically.
Therefore, in the process of project implementation, attention should pay to divergent thinking and innovative management concepts. To be profitable, an enterprise cannot do without management. How to manage the construction of bridges and roads is not only related to the profitability of the enterprise. But also related to the daily driving safety of people.
Current status of bridge construction management
The development of the city has increased the scale of public facilities construction. And the increase in road and bridge construction projects and the acceleration of construction have exposed many engineering loopholes. In this case, some enterprises often Regardless of the quality of the project, blindly catch up with the speed. Which leads to the emergence of many hidden dangers and problems l. “Survival by quality, benefit from management”, is the eternal purpose of an enterprise to obtain profits. The construction management project needs to effectively manage the contract signed by the construction enterprise. Or the various work requirements and specific contents put forward in the contract.
It required the enterprise must guarantee the construction quality and efficient management system under the premise of the contract. To improve the profit amount and management level of the enterprise. Thereby improving the overall economic benefits of society and the efficient allocation of production factors. Among them, bridge construction project management has determined its position in the construction of public facilities with its complexity, sociality, system, and integrity.
Other things
The unreasonable use of early engineering projects or their quality problems often leads to the renovation and reconstruction of bridges and roads. Which causes a waste of manpower, material resources, and resources, and also brings certain potential dangers. The fixity, agreement. And the diversity of construction projects determines the particularity of construction management. The content of management will change correspondingly within a certain period. There must be a high degree of organization and coordination.
The above characteristics of project management Both require the construction manager to change the corresponding strategy according to the time and content changes in the process of managing the project and require the manager to have excellent organizational strengthening ability. The selection of materials, the management of construction quality, and the construction environment are all important factors affecting the management and construction of bridges.
Therefore, in the process of bridge construction, it is even more necessary to improve the management of construction quality, and for some factors that can affect the quality of bridges, it is necessary to Control and manage it, strive to obtain the maximum profit with the minimum loss, to ensure the quality of the whole project without problems, and at the same time reduce the occurrence of traffic accidents.
Problems in bridge construction
Defects in construction
Hazards of asphalt concrete pavement
The most common diseases are push, cracks, and oil flooding. Most of them are caused by unreasonable asphalt quality or concrete-specific gravity. And the quality problems in the process of engineering operation will cause hazards to bridges and roads.
Cracks in concrete bridges
The load capacity of the bridge is far more than its bearing capacity. The thermal expansion and contraction of the concrete make the bridge deck expand and crack due to the large temperature difference between the inside and the outside, and the concrete does not mix and is dense during construction. These are the reasons for the web cracks in the bridge. For bridge hazards, it is necessary to do regular inspections, check hidden dangers through monitoring, strengthen the management of construction quality, and pay attention to the regular protection of bridges.
Subgrade problems
The roadbed is the basic component of a road and the main part of the road surface. Poor drainage is the main cause of roadbed diseases. Long-term poor drainage of the road surface will cause the roadbed to be soft and the strength will be reduced. The insufficient stability of the roadbed soil will cause landslides and other accidents.
At this time, the vehicle operator will increase the softness of the subgrade, forming a vicious circle. The collapse of the embankment slope will cause traffic safety hazards. To control subgrade disease, it is necessary to design the pavement according to local conditions and actual conditions. Vehicles are restricted during the health preservation period, and boards and corbel beams are set up on the roadside to reinforce the embankment.
Problems in management
- (1) The initial bidding management system was not rigorous, and unreasonable competition often occurred due to the incomplete bidding system, and the construction cost was too low due to blindly suppressing prices, cutting corners when implementing projects, frequent tofu dregs projects, and the market The competition caused the enterprises to fall into economic difficulties, and the shortage of funds also restricted the further development of the project.
- (2) The credit problem of the construction party itself. Enterprises often breach the contract because they don’t pay attention to the credit problem, don’t pay attention to the construction quality, and delay the construction speed, which all lead to the reduction of the project quality.
Management measures for bridge engineering
Management of project material cost
There will be many consumable items in bridge construction, such as sand, gravel, cement, and some small machines. It is necessary to do a good job recycling these perishable items, strictly control the use of these items, and minimize loss. For example, when using items such as cement and steel bars, pay attention to the measurement to reduce the loss of raw materials, pay attention to the storage of small machines after storage, and repair damaged machines in time. The inventory materials must place reasonably, corresponding signs must stand set up and the reporting procedures should do well.
Management of construction quality
The quality of bridges is not only related to the investment efficiency of enterprises. But also related to the safety of the people, so it should not underestimate. To do a good job in quality management, it is necessary to ensure quality before construction. That is, to carry out preparatory work such as inspection of the project before the official construction. This work must carry out throughout the entire construction process, and random checks carried out at any time. It is necessary to strengthen the construction of the supervision and management system to make the construction party fully aware of the importance of quality assurance.
The enterprise must follow the agreed supervision procedures, conduct sampling surveys before the materials are officially put into use, and set project goals during the construction process. Due to the adjustment and modification of the engineering process, the appropriate mechanical equipment should reasonably select. During the construction process, professionals must conduct sampling inspections at any time according to technical requirements, grasp the progress and quality of the project, and submit inspection reports. For quality problems, relevant personnel must be resolutely and severely punished to prevent cutting corners.
Management of engineering technology
Bridge construction is a complex project with high intensity and high technical requirements. During the implementation process, management measures require continuous updates to ensure the implementation of technology. Therefore, technical management runs through the entire construction process. To strengthen technical management, the first thing is to pay attention to the selection of high-quality technical and management personnel.
They should supervise and inspect each other, analyze possible problems, and cannot cover up each other. Technicians and construction parties should write reports to record the construction situation every day, observe the construction trend and provide appropriate technical adjustments, and use the measuring instruments effectively and accurately. In addition, it is necessary to implement an effective shift management system to help construction personnel establish a rigorous quality concept, pay attention to efficiency and ensure quality at the same time.
Epilogue
By studying the project management of bridge construction, we can see that bridge construction management is very complicated work, and there are various problems in bridge construction in our country today, and necessary measures should take to address these problems in construction to ensure Improved project quality, remove hidden dangers, and ensure the stable development of enterprises, thereby promoting the urbanization of our country.
