Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the content of the present invention is not limited to the stated scope.

[0046] Such as Figure 1-4 The lowering and drainage system of the sunken foundation pit shown mainly includes the water collection well 1, the drainage well 4, the blind ditch 3 and the open ditch 2; Around the bottom of the foundation pit, two adjacent water collection wells 1 are connected through an open ditch 2; the number of dewatering wells 4 is 4, and they are evenly arranged in the center of the foundation pit. The water well 4 diverges from the center of the "ten" and is connected to the blind ditch 3 diverging from the adjacent dewatering well 4, while the blind ditch 3 diverging to the four sides of the foundation pit is connected to the open ditch 2, forming a criss-cross ditch network. 3 is located inside the open ditch 2.

[0047]The open ditch 2 is connected t...

Abstract

The invention provides a sinking type foundation pit dewatering and draining system. The sinking type foundation pit dewatering and draining system mainly comprises water collecting wells, dewateringwells, blind ditches and open ditches. The water collecting wells are arranged at every corner of the foundation pit. The open ditches are formed in the periphery of the bottom of the foundation pit.Adjacent two water collecting wells are connected by one open ditch. The dewatering wells are uniformly formed in the foundation pit according to on-site requirements. The well openings of the dewatering wells are lower than the bottom plate of the foundation pit. The blind ditches extend in a cross shape with the dewatering wells as the centers. The blind ditches extending from adjacent dewatering wells are connected. The blind ditches extending to the periphery of the foundation pit are connected with the open ditches. In this way, a network of crisscrossing ditches is formed. The dewateringand draining system can well solve the problems that draining of the foundation pit is slow and draining is difficult. The draining efficiency is high. The sinking type dewatering and draining systemdoes not influence running of construction machines in the foundation pit. Construction efficiency and continuity can be guaranteed. The invention further provides a construction method and an application method of the dewatering and draining system.

Description

technical field [0001] The invention relates to a submerged foundation pit drainage system, a construction method and a use method, and belongs to the technical field of foundation pit engineering. Background technique [0002] With the rapid development of my country's economy, more and more high-rise super high-rise buildings are constantly standing in the city in the process of urban construction, and the underground space projects are also increasing and deeper. Skyscrapers are built on high places, and underground lost cities are also built underground. People pay more and more attention to foundation pit engineering. The location designated by the design is carried out, and one of the biggest problems is the drainage of the foundation pit. Due to the effect of groundwater, water often accumulates in the foundation pit, especially when it encounters good water permeability soil. Rapid drainage is necessary to ensure safe and efficient operations in foundation pits. Cont...
