Foundation pit drainage and protection system capable of being assembled and recycled

Abstract

The invention discloses a foundation pit drainage and protection system capable of being assembled and recycled. The foundation pit drainage and protection system comprises horizontally-arranged drainage devices arranged at the two ends of a concrete pavement of a foundation pit, a water retaining device is arranged between the drainage device arranged at the upper end of the foundation pit and the foundation pit, and the drainage devices and the water retaining device are all factory prefabricated members. By means of the drainage devices and the water retaining device prefabricated in a factory, the drainage devices and the water retaining device can be utilized repeatedly, the utilization rate of materials can be increased, and the building time and the dismounting time of the drainage devices and the water retaining device can be shortened. U-shaped or inverted-trapezoid-shaped drainage grooves are adopted in the system, so that manufacturing is facilitated, the drainage amount is large, and water can be drained fast. Steel pipes are arranged at the bottoms of protection rods, threads are arranged on the outer portions of the steel pipes, and therefore the protection rods can be screwed in and out of a retention wall conveniently, labor hours are shortened, and meanwhile repeated utilization of the protection rods is achieved. The whole drainage and protection system is simple in structure, the repeatable recycling rate of all components is high, and effective drainage of underground construction can be achieved.

Description

technical field [0001] The invention relates to underground engineering foundation pit drainage and protection, in particular to a recyclable foundation pit drainage and protection system that can be assembled. Background technique [0002] In underground engineering, during foundation pit construction, in order to ensure the normal progress of construction, effective drainage is required. Drainage ditches are often set on the bottom and top surfaces of the foundation pit to drain the water in the foundation pit in an organized manner. Usually, the drainage ditch needs to use rectangular brick drainage ditch, but the brick drainage ditch generally needs to go through the steps of foundation cushion, brick laying on both sides of the drainage ditch, and cement mortar on the brick surface. The construction steps are not only cumbersome, but the construction period is long. At the same time, after the underground project is completed, the bricks used in the drainage ditch are u...

Problems solved by technology

Usually, the drainage ditch needs to use rectangular brick drainage ditch, but the brick drainage ditch generally needs to go through the steps of foundation cushion, brick laying on both sides of the drainage ditch, and cement mortar on the brick surface. The construction steps are not only cumbersome, but the construction period is long. At the same time, after the underground project is completed, the bricks used in the drainage ditch are usually disassembled and treated as construction waste, resulting in a waste of materials and the reuse of the materials used in the drainage ditch cannot be realized. Furthermore, as the price of bricks continues to increase, the construction of drainage ditch Costs are also increasing year by year

[0003] It is precisely because of the important role of the drainage ditch, but the existing technology not only increases the construction cost, but also has a low recycling rate of materials, so there is a need for a new recyclable drainage device suitable for underground engineering

[0004] In addition, it is necessary to install a water retaining wall around the foundation pit to avoid damage to the foundation pit. However, the current construction steps of the water retaining wall are cumbersome, the construction period is long, and the materials cannot be reused, resulting in waste of work costs and materials. At the same time, Drains and retaining walls are artificially built, which is prone to leakage at the joints during the drainage process
