Embodiment 1

[0038] Such as Figure 1~5 Shown, a kind of high water level basement basement waterproof construction method comprises the following steps:

[0039] (1) First, use the water-stop curtain of the foundation pit support to stop the water in the soil layer in the depth range of the foundation pit 18 from the periphery of the foundation pit 17, and at the same time, set a through hole on the ground 17 of the foundation pit support and the periphery of the bottom of the foundation pit. gutter 1;

[0040] (2) Set up more than one drainage ditch 3 made of loose bricks and fiber nets below the interval between the pile caps of the basement floor, and the bottom 2 of the pile caps is 500-1000 mm from the top of the drainage ditch 3;

[0041](3) Corresponding dewatering wells 4 are arranged at the outlet of the drainage ditch 3 around the foundation pit 1, and the dewatering wells 4 are arranged outside the outermost edge 5 of the basement foundation. It communicates with the drainage...

Embodiment 2

[0050] The difference between this embodiment and Embodiment 1 lies in that the planar layout of the drain ditch 3 in the step (2) is a curved structure, and the outlet end of the drain ditch 3 communicates with the dewatering well 4 in the step (3). That is to say, the drainage ditch 3 in the present embodiment can be bent between the caps, as long as the water can be sent to the dewatering well 4.

Abstract

The invention discloses a waterproof construction method for a bottom plate of a high-water-level basement. The method comprises the following steps of: (1) partitioning water on a soil layer in a depth range of a foundation pit from the periphery of the foundation pit by using a waterproof curtain of a foundation pit support, and forming drainage ditches on the ground surface of the foundation pit support and at the bottom periphery of the foundation pit; (2) forming more than one dredging ditch below partitioning positions among pile bearing platforms, wherein the distance between the bottom of each pile bearing platform and the top of the dredging ditch is 500 to 1,000mm; and (3) forming a corresponding dewatering well at the periphery of the foundation pit according to a water outlet end of the dredging ditch, and arranging a submerged pump in the dewatering well, wherein the submerged pump is communicated with the drainage ditches through water suction pipes. The invention also discloses a waterproof system for the bottom plate of the high-water-level basement. By the method and the system, the problems of low dryness of flexible waterproof layer construction surfaces, over-high cost of jet grouting piles, high water seepage degree, high labor consumption, high material consumption and the like in the prior art are solved; and the system has the characteristics of effectively dewatering the basement, shortening construction periods, saving the cost and conveniently controlling construction quality, along with a simple structure, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of basement floor waterproof construction in civil engineering, in particular to a high water level basement floor waterproof construction method and a system thereof. Background technique [0002] With the improvement of the level of underground engineering in architectural design, the use function of the basement will not only be used for underground air defense, underground garages and other purposes. Due to the shortage of urban construction land and following the popular trend of international buildings to expand space underground, the building use space (layer) is deeply expanded underground, and underground offices and underground commercial shopping plazas are becoming more and more diverse. At present, the basements of buildings in the low-lying alluvial areas of the Yangtze River and Pearl River Delta in my country are multi-layered, and the diversification of functions is becoming more and more pr...
