Abstract
The utility model relates to an architectural engineering technology field, concretely relates to well point dewatering is structure in pit. Including the well body, the well is internal to be equipped with the filter tube and by the external well water pipe that stretches into in the filter tube of well, the filter tube bottom is equipped with the head that catchments, catchment first lower part for spherical, catchment and link to each other with the inner wall of filter tube behind the upper portion edge bend of head, catchment overhead portion at a kink of formation of buckling, the head that catchments has the filter mantle, filter mantle and catchment and form the filter chamber between the head, the filter mantle bottom is equipped with filter open, be located filter open department in the filter chamber by the lower supreme guard net that is equipped with in proper order, coarse strainer and thin filter screen, the inside wall of kink is equipped with the intercommunication filter chamber and the inside interior apopore of head that catchments, the lateral wall of kink is equipped with the outer apopore about the intercommunication. Precipitation can be accelerated to this structure, avoids the earth's surface to take place to subside.
Description
Technical field
This utility model relates to construction engineering technical field, is specifically related to a kind of well-points dewatering underground structure.
Background technology
The Application of light well point precipitation that construction site base pit dewatering is used, uses the water suction well-point pipe burying many certain depths at construction area underground at ordinary times, installs water suction house steward on ground and pumping equipment constitutes a set of pumping system.Then start water plug from the continuous groundwater absorbing of well-point pipe, make the subsoil water in place be gradually lowered certain depth, thus reach the purpose of precipitation.During well-points dewatering, usually can settle owing to water causing earth's surface with silt.This problem is all there is in current precipitation mechanism in carrying out large-area big water-holding quantity Precipitation Process.
Summary of the invention
The purpose of this utility model is to solve current precipitation mechanism when the precipitation work that the soft water yield of some soil properties is bigger, the problem being easily caused ground settlement existed, it is provided that a kind of well-points dewatering underground structure
In order to reach above-mentioned utility model purpose, this utility model by the following technical solutions:
A kind of well-points dewatering underground structure, including well body, is provided with filter tube and by the external well water pipe extending in filter tube of well in well body；Collecting head it is provided with bottom filter tube; collecting head bottom is spherical; it is connected with the inwall of filter tube after the top edge bending of collecting head; one kink is formed in bending place at collecting head top; collecting head has filter mantle; filter chamber is formed between filter mantle and collecting head; filtration mouth it is provided with bottom filter mantle; it is positioned in filter chamber at filtration mouth and is sequentially provided with catch net, coarse strainer and fie screen from the bottom to top; collecting head upper portion side wall is provided with the interior apopore being communicated with within filter chamber and collecting head, and the lateral wall of kink is communicated with upper and lower outer apopore.
As preferably, the top edge of filter mantle is connected with kink.
As preferably, fie screen top is provided with supporting network.
As preferably, it is extended to the over below filter bowl bottom filter tube, and receives in the mouth of pipe of filter tube.
This utility model compared with prior art, provides the benefit that: this structure can accelerate precipitation, it is to avoid earth's surface settles.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial structurtes schematic diagram of bottom of the present utility model.
In figure: 1 well body, 2 filter tubes, 3 well water pipes, 4 collecting heads, 5 kinks, 6 filter mantles, 7 filter chambers, 8 filter mouth, 9 catch nets, 10 coarse strainers, 11 fie screens, apopore in 12,13 outer apopores, 14 supporting networks.
Detailed description of the invention
Below by specific embodiment, the technical solution of the utility model is further described explanation.
