The cast iron pipe used in the traditional well point dewatering method is inserted into the ground, the equipment is heavy and is not easy to move and adjust, the operation process is complicated, and the investment cost is high. In the traditional precipitation, because a water collecting pit, an elevator shaft and other local reducing structures are frequently arranged in a foundation pit, the precipitation of the foundation pit is difficult to control to be 500mm below a base, the base is accumulated with water when a groove is tested, the pit wall has quicksand, the soil at the bottom of the pit is disturbed, the waterproof construction base is not dry, and the potential quality and safety hazards such as water resistance are overcome; meanwhile, the cast iron pipe inserted underground is easy to block and is not easy to clean.
The utility model has the following contents:
an object of the utility model is to provide a simple structure realizes effective precipitation, and avoids the deep basal pit well point dewatering device of pipeline jam.
The utility model discloses by following technical scheme implement: the patent aims at providing a deep foundation pit well point dewatering device which comprises a main pipe, branch pipes and needle tubes; a plurality of branch pipes are arranged on the main pipe in a communicating manner, one ends of the branch pipes are fixedly communicated with the main pipe, the other ends of the branch pipes are fixedly communicated with one end of the needle tube, and the other end of the needle tube is arranged in a tip shape; a plurality of water suction ports are formed in the side wall of the needle tube; the outer side wall of the needle tube is wrapped and fixed with a filter screen.
Further, the device also comprises a water feeding pump, a water source and a water suction pump; the water inlet of the main pipe is communicated with the water outlet of the water feeding pump, the water inlet of the water feeding pump is communicated with the water source, and the water outlet of the main pipe is communicated with the water inlet of the water suction pump.
Further, a check valve is installed in each of the water suction ports.
Furthermore, the branch pipe and the needle tube are both PPR pipes.
The utility model has the advantages that: 1. the utility model has simple structure and easy realization, and the plurality of needle tubes of the utility model are inserted into the foundation pit, and the water pump pumps water, thereby effectively ensuring the construction quality of foundation pit dewatering and shortening the dewatering construction period; effectively solved local elevartor shaft of foundation ditch, sump pit etc. precipitation difficulty, waterproof construction has the problem of quality hidden danger. The operation conditions of constructors are improved, the field base disturbance is greatly reduced, water permeation and water leakage accidents are prevented, and the operation surface is safely and effectively utilized; 2. the branch pipe and the needle tube of the utility model are PPR pipes, the weight is light, the moving and the installation are convenient, and the construction cost is reduced; 3. when the needle tube is inserted into the foundation pit, the water is pumped by the water pump, the water flows out from the tip end of the needle tube, the needle tube is inserted into the designed position by using the slurry wall protection punching method, the operation is convenient, and meanwhile, the slurry wall protection punching method can ensure that the needle tube is not blocked and avoid the blockage of the needle tube.
Description of the drawings:
in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
