Abstract
The utility model discloses a kind of deep basal pit explosion discharge structure, including building is in the ground-connecting-wall of foundation ditch surrounding and sets in the precipitation pipe well of bottom of foundation ditch, blast hole and drainage trench, the drainage trench is connected with the precipitation pipe well, in the precipitation pipe well is provided with dewatering pump.This utility model is by using the structure that drainage trench is arranged in bottom of foundation ditch, using drainage trench by foundation ditch due to the reasons such as explosion formed Bedrock Crevice Water drain in dewatering well, it is pumped to outside foundation ditch using the dewatering pump in dewatering well, the Bedrock Crevice Water white-out that effectively foundation ditch explosion can be formed is clean, reaches expected dewatering effect.
Description
Technical field
This utility model is related to a kind of deep basal pit explosion discharge structure, is mainly used in railway traffic engineering and building construction
Deep basal pit substrate blasting engineering draining.
Background technology
The draining of current track traffic engineering and building construction deep basal pit blasting engineering is mainly carried out using dewatering well, precipitation
Well is to ensure one of measure of foundation ditch smooth construction.As basement rock can be shattered by foundation ditch explosion, various cracks are formed, causes basement rock
Crevice water is oozed out from crack, and traditional tube well dewatering pipe well effect is poor, it is impossible to the subsoil water in timely white-out foundation ditch.
The content of the invention
This utility model provides a kind of deep basal pit explosion discharge structure to solve technical problem present in known technology,
The Bedrock Crevice Water white-out that foundation ditch explosion effectively can be formed by the structure is clean, reaches expected dewatering effect.
This utility model is adopted the technical scheme that by solving technical problem present in known technology：A kind of deep basal pit
Explosion discharge structure, including building foundation ditch surrounding ground-connecting-wall and set the precipitation pipe well of bottom of foundation ditch, blast hole and
Drainage trench, the drainage trench are connected with the precipitation pipe well, in the precipitation pipe well are provided with dewatering pump.
Metalling or coarse sands layer are equipped with the drainage trench.
The drainage trench is connected between two precipitation pipe wells.
The depth of the drainage trench is not more than 20cm, and width is less than 20cm.
The diameter of the precipitation pipe well is not less than 315mm.
This utility model has the advantages and positive effects that：By adopting the structure that drainage trench is arranged in bottom of foundation ditch,
Using drainage trench by foundation ditch due to the reasons such as explosion formed Bedrock Crevice Water drain in dewatering well, using in dewatering well
Dewatering pump is pumped to outside foundation ditch, and the Bedrock Crevice Water white-out that effectively can be formed foundation ditch explosion is clean, is reached expected
Dewatering effect.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1st, ground-connecting-wall；2nd, dewatering pump；3rd, precipitation pipe well；4th, blast hole；5th, drainage trench.
Specific embodiment
For the content of the invention of the present utility model, feature and effect can be further appreciated that, following examples are hereby enumerated, and is coordinated
Accompanying drawing describes in detail as follows：
Fig. 1, a kind of deep basal pit explosion discharge structure, including building are referred in the ground-connecting-wall 1 of foundation ditch surrounding and is set
Precipitation pipe well 3, blast hole 4 and drainage trench 5 in bottom of foundation ditch, the drainage trench 5 is connected with the precipitation pipe well 3, described
Dewatering pump 2 is provided with precipitation pipe well 3.
In the present embodiment, metalling is equipped with the drainage trench 5, it is also possible to lay in the drainage trench 5 thick
The larger material layer of layer of sand or other permeabilitys.The drainage trench 5 is connected between two precipitation pipe wells 3, but is not limited to
In this, drainage trench 5 can connect everywhere, or part connection with the connection of precipitation pipe well, can be according to bedrock fracture
Water practical situation determines.The depth of the drainage trench 5 is not more than 20cm, and width is less than 20cm.The diameter of the precipitation pipe well 3
Not less than 315mm.
The construction method of above-mentioned discharge structure：
1) on ground first according to design requirement construction ground-connecting-wall 1 and precipitation pipe well 3, it is ensured that ground-connecting-wall 1 and precipitation pipe well 3 hang down
Straight degree and building-in depth meet requirement.
2) treat that excavation of foundation pit, to the rock basal plane for wanting explosion, sets blast hole 4 at hole bottom with rig.
3) drainage trench 5 is excavated in the position for having Bedrock Crevice Water after the completion of to be blasted, and rubble is laid on drainage trench
Or the material layer that other permeabilitys are larger.
4) by outside the foundation ditch of the Bedrock Crevice Water pump drainage being pooled in precipitation pipe well 3 by drainage trench 5.
Although being described to preferred embodiment of the present utility model above in conjunction with accompanying drawing, this utility model is not
Above-mentioned specific embodiment is confined to, above-mentioned specific embodiment is only schematic, is not restricted, ability
The those of ordinary skill in domain under enlightenment of the present utility model, without departing from this utility model objective and claimed
In the case of scope, many forms can also be made, these are belonged within protection domain of the present utility model.
