Description

Drainage system is stabilized to foundation ditch

Technical Field

The application relates to the technical field of foundation pit drainage systems, in particular to a stable drainage system for a foundation pit.

Background

The foundation pit is a soil pit excavated at the design position of the foundation according to the elevation of the foundation and the plane size of the foundation. During the foundation ditch excavation, ground water level can be higher than the foundation ditch bottom surface, and groundwater can constantly permeate the hole in, because factor influences such as precipitation, the foundation ditch produces ponding easily simultaneously. In order to ensure that construction can be carried out on the bottom surface of a dry foundation pit; meanwhile, the conditions of instability of a foundation pit side slope, basic quicksand, pit bottom uplift, foundation bearing capacity reduction and the like caused by long-time water accumulation on the bottom surface of the foundation pit are reduced. Need be in carrying out the drainage to the foundation ditch bottom after foundation ditch excavation is accomplished for outside the water in the foundation ditch can in time discharge foundation ditch, the condition that reduces foundation ditch ponding appears, makes the side slope and the ground of foundation ditch more firm, makes the construction of foundation ditch safer more

In the related technology, the foundation pit drainage method is usually an open trench plus sump drainage method, during construction, a sump is firstly dug at the bottom of a foundation pit, an open trench is dug at the bottom of the foundation pit, and the open trench is communicated with the sump; meanwhile, the water collecting well is communicated with a water discharging pipe, the water discharging pipe is provided with a water discharging pump, during water discharging, the water seepage on the slope surface of the foundation pit and the rainwater flowing into the foundation pit in rainy days flow into the open ditch firstly and then flow into the water collecting well through the open ditch, and when the water quantity of the water collecting well reaches a certain quantity, the water discharging pump is opened to discharge the water of the water collecting well, so that the water is not easy to accumulate in the foundation pit.

To the correlation technique among the aforesaid, the rainwater of foundation ditch side slope infiltration and inflow foundation ditch often can carry a large amount of gravel and sand for water in the sump pit contains a large amount of gravel and sand, and long-term in the past, gravel and sand can be to the drain pump wearing and tearing, leads to influencing the drainage efficiency of drain pump and drain pump also blockked up by gravel and sand easily, and the inventor thinks that the gravel and sand in the foundation ditch ponding blocks up the drain pump easily and then influences the condition of drain pump drainage efficiency.
