Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

[0037] like figure 1 and 2 As shown, an embedded shallow composite drainage pipe includes a well pipe 1, a water stop ring 2, a water filter well main pipe 3, a water filter well branch pipe 4, and a water filter hole 5.

[0038] Wherein, the water filter well main pipe 3 is vertically pre-buried at the bottom of the sump in the foundation pit, the water filter well main pipe 3 is a barrel-packed structure with a closed bottom, and a plurality of water filter holes 5 are arranged on the side wall of the water filter well main pipe 3 to prevent water seepage. The seepage water in the pit enters in the water filter well main pipe 3 through the water filter hole 5, and the diameter of the water filter well main pipe 3 is determined and adjusted according to the seepage area and the water v...

Abstract

The invention discloses an embedded type superficial layer combination drainage pipe which comprises a filter pipe, a seal ring and a well pipe. Multiple filter holes are formed in the filter pipe andare used for collecting seepage water in a foundation pit; the seal ring is arranged on the top part of the filter pipe and is used for preventing the seepage water from seeping upwards; and the wellpipe is arranged on the top part of the seal ring and communicates with the filter pipe. The subsurface seepage water in the foundation pit is collected by adopting superficial layer combination drainage, the foundation pit is removed by adopting a water pump, and meanwhile, the seal ring effectively prevents the seepage water in a water collecting pit from inversely seeping upwards, so that precipitation construction can be carried out without the need of professionals, the cost is low, and the requirement on local superficial layer precipitation for underground construction can be met.

Description

technical field [0001] The invention relates to the field of building construction waterproofing, in particular to an embedded shallow composite drainage pipe and a construction method. Background technique [0002] In recent years, with the sustained and rapid development of my country's construction industry and other projects involving basic operations, there are more and more underground projects, and the scale is also growing. Underground engineering is difficult to construct due to complex geological conditions. The groundwater level of some underground projects is relatively high, so the groundwater level is often lowered during project construction. [0003] Precipitation methods commonly used at present are: open ditch plus collection well drainage method, light well point method, jet well point method, tube well point method, deep well point method and comprehensive well point method, water stop curtain method, etc. These methods not only require a large amount o...
