Description

Technical Field

[0001] The present disclosure relates to the field of construction site foundation technology, and in particular to a construction site protective drainage system. Background Art

[0002] With the acceleration of urbanization, the construction industry has developed rapidly, and the number of construction sites has continued to increase. However, construction sites face many challenges during the construction process, especially construction safety and environmental protection issues. In the traditional construction process of construction sites, the protection and drainage systems are often designed and constructed separately. The protection system mainly includes facilities such as foundations, standardized guardrails and safety nets, which are used to ensure the safe isolation and personnel protection of the construction site. The drainage system involves facilities such as ground drainage ditches, drainage pipes and temporary water collection wells, which are designed to solve the problems of rainwater discharge and groundwater control on the construction site. Although these two systems each play an important role, there are the following problems in actual operation:

[0003] (1) Separate design leads to waste of resources: The independent design of the protection and drainage systems often results in the duplication of materials and space, increasing project costs and construction complexity.

[0004] (2) Low construction efficiency: Since the construction of the two systems needs to be carried out separately, this prolongs the preparation time of the project and affects the overall construction progress.

[0005] (3) Safety hazards: Traditional drainage systems may not drain properly under extreme weather conditions. Water accumulation may cause the construction site to become muddy, increasing the risk of slipping for construction workers and also affecting construction quality.

[0006] (4) Environmental impact: Inadequate drainage measures may result in sewage and sediment being discharged directly into the surrounding environment, causing water and soil pollution.

[0007] (5) Difficulty in maintenance: Separate systems may require separate maintenance during later use, which increases maintenance costs and the difficulty of management work. Utility Model Content

[0008] The purpose of the utility model is to solve the above-mentioned problem and provide a construction site protective drainage system.
