Abstract
The utility model provides a kind of base pit dewatering well and crosses water pipe safeguard structure, cross water pipe along the circumferential direction distributing installation on well, cross the side wall of water pipe insertion well, enclosed on the outside of well and be provided with the channel-section steel that notch is inwards set, it is described to cross the inner side that water pipe may be contained within channel-section steel, and setting is closed between channel-section steel and well outer wall, the bottom land of channel-section steel offers water hole.It is poor to solve existing conventional safeguard structure weight capacity, and the stronger safeguard structure construction cost of load-bearing is high, the cycle is long, and tool has some limitations.The utility model belongs to drainage construction field.
Description
Technical field
The utility model is related to a kind of job site waterproof construction, belongs to drainage construction field.
Background technology
Conventional job site waterproof is based on unimpeded.Draining is usually to build weeper drain or take ground away using pipe well
Lower water.The building of weeper drain needs certain water pressure or manually manufactures drainage grade, is seeped water for large area and existing
The construction method of the larger local weeper drain of field construction surface has certain limitation.Water blockoff（Manufacture water-stop curtain）And pipe well
Precipitation is then needed along well-point pipe is buried around foundation ditch, and the construction method cycle is more long, and is covered by neighbour building for surrounding place
The field construction of lid is more inconvenient.And after substantial amounts of underground water is pumped discharge.The buoyancy force of underground water in the region can decline, surrounding
Building and underground utilities will produce differential settlement, the structure safety of the neighbour building of influence.To solve the above problems, design
A kind of base pit dewatering well, but crossing water pipe periphery and need to cover multiple filtration Rotating fields due to this well, its peripheral load-bearing
Greatly, therefore, need to design that a kind of weight capacity is extremely strong, the water of filtering can be effectively ensured again by what water pipe entered well and cross water pipe
Safeguard structure.
The content of the invention
The purpose of this utility model is：A kind of base pit dewatering well is provided and crosses water pipe safeguard structure, it is existing normal to solve
The safeguard structure weight capacity of rule is poor, and the stronger safeguard structure construction cost of load-bearing is high, the cycle is long, and with certain office
Sex-limited problem.
To solve the above problems, intend crossing water pipe safeguard structure using such a base pit dewatering well, cross water pipe circumferentially
Directional spreding is installed on well, crosses the side wall of water pipe insertion well, is enclosed on the outside of well and is provided with notch and inwards sets
Channel-section steel, the water pipe of crossing may be contained within the inner side of channel-section steel, and closed between channel-section steel and well outer wall and set, and the bottom land of channel-section steel is opened
It is provided with water hole.
It is foregoing to cross in water pipe safeguard structure, the steel sleeve that water pipe is a diameter of 100mm is crossed, water pipe is crossed in well base surface mark
The position of 1m is distributed by spacing 150mm and set on height；
It is foregoing cross water pipe safeguard structure in, well be square hoistway structure, the channel-section steel by set along square arrangement four
Section straight trough steel is welded from beginning to end successively, and the model of every section of straight trough steel is 14b, i.e. height 140mm, leg 60mm wide, and waist is thick
8mm。
Compared with prior art, well described in the utility model crosses water pipe safeguard structure on the premise of weight capacity is ensured
Structure is more simple, easy construction, and short construction period, more practical, does not interfere with the structure safety of neighbour building, effectively protects
Hinder the normal operation of base pit dewatering well.
Brief description of the drawings
Fig. 1 is main view cross-sectional view of the present utility model.
Specific embodiment
To make the purpose of this utility model, technical scheme and advantage clearer, below will be new to this practicality by accompanying drawing
Type is described in further detail.
Embodiment：
Referring to the drawings 1, the present embodiment provides a kind of base pit dewatering well and crosses water pipe safeguard structure, and it is a diameter of to cross water pipe 2
The steel sleeve of 100mm, crosses water pipe 2 and is along the circumferential direction distributed setting by spacing 150mm in the position of 1m on the base surface absolute altitude of well 1
In on well 1, the side wall of the insertion well 1 of water pipe 2 is crossed, the outside of well 1 encloses and is provided with the channel-section steel 3 that notch is inwards set,
It is described to cross the inner side that water pipe 2 may be contained within channel-section steel 3, and setting is closed between channel-section steel 3 and the outer wall of well 1, the bottom land of channel-section steel 3 is opened up
There is water hole 31；
Well 1 is square hoistway structure, and the channel-section steel 3 is welded from beginning to end successively by the four sections of straight trough steel set along square arrangement
Form, the model of every section of straight trough steel is 14b, i.e. height 140mm, leg 60mm wide, waist thickness 8mm.
Geofabrics cloth 4, cobblestone 5, geofabrics cloth 4 and rubble filter layer 6, goose ovum are laid successively in the outside of channel-section steel 3
The laying height of stone 5 is 1m, according to 1:1.5 gradient carries out slope, and the laying depth of rubble filter layer 6 is 0.4m, the well of well 1
Maintenance cat ladder 7 is installed in road.
The construction method of the well is as follows：
Step one：Excavation and precipitation foundation ditch；
Step 2：Well structure is constructed, constructed on the basis of precipitation foundation ditch well 1, the 1m on well base surface absolute altitude
Position distribution clipping room away from a diameter of 100mm of 150mm cross water pipe 2, cross the insertion well 1 of water pipe 2 side wall, meanwhile, in mistake
A row is installed in the periphery of water pipe 2 is used to fix the reinforcing bar of channel-section steel 3；
Step 3：Channel-section steel is installed, channel-section steel 3 is installed in the outside of well 1, the processing method of channel-section steel 3 is：
