Abstract
The invention belongs to technical field of buildings, disclosing a kind of underground water pressure relief device and method, underground water pressure relief device is the pressure release that underground water is carried out with the principle of linker；Underground water pressure releasing method includes: to understand level of ground water by geological exploration, data collection；Reasonable measure is taken to reduce the buoyancy of underground structure；Building anti-floating after Structure Calculation pressure release；Waterproof and drainage sunk well after basement pressure release；Corresponding emergency measure.The present invention does not have to external force and removes anti-buoyancy force of underground water, takes measures to reduce external water buoyancy；Need external force that anti-power is gone also to reduce, the quantity of the corresponding anti-float anchor rod for reducing basement or the counterweight for reducing basement anti-floating reduce the anti-floating project cost of underground structure.
Description
Technical field
The invention belongs to technical field of buildings more particularly to a kind of underground water pressure relief device and methods.
Background technique
Currently, the prior art commonly used in the trade is such that
With the continuous development of China's urbanization, urban construction constantly wants space to aerial and underground.Urban construction
Space problem is relatively good in the air solves the problem of but not only to solve soil pressure in the development of the underground space, also relates to ground
The anti-floating of the problem of being lauched underground structure occupies very big specific gravity in project cost.The thinking one of the anti-floating of basement building
All it is " anti-" word as soon as, that is, has great water buoyancy to be gone to resist this buoyancy with great external force, is the equal of to resist strenuously
Power, very stiff and demanding reason.The quantity of the anti-float anchor rod of basement is more, and the counterweight of basement anti-floating is high, the anti-floating of underground structure
Project cost is high.
In conclusion problem of the existing technology is:
(1) it needs to remove anti-buoyancy force of underground water with external force in the prior art, external water buoyancy cannot be reduced.It needs to increase underground
The quantity of the anti-float anchor rod of room or the counterweight of basement anti-floating cause the anti-floating project cost of underground structure high.
Solve the difficulty of above-mentioned technical problem:
When level of ground water increases suddenly in the case where often meeting water level, the measure of anti float being arranged under often chance water level will fail.
It solves the meaning of above-mentioned technical problem: being increased suddenly when meeting level of ground water in the case where imprevision, guaranteed
The safety of underground structure.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of underground water pressure relief device and methods.
The invention is realized in this way a kind of underground water pressure releasing method, the underground water pressure releasing method include:
The first step obtains level of ground water information；
Second step reduces the buoyancy of underground structure；
Third step calculates building anti-floating after pressure release.
4th step, waterproof and draining after carrying out basement pressure release.
Further, waterproof and draining after, also need to carry out corresponding emergency measure.
Another object of the present invention is to provide a kind of underground water pressure relief device for implementing the underground water pressure releasing method, institutes
Underground water pressure relief device is stated to be provided with
Sump；
It is equipped with plain concrete bed course on sump, cobble or scree are provided on sump, is laid on cobble or scree
There are anti-filter geotextiles；
Grit or aggregate chips are provided between cobble or scree and anti-filter geotextiles.
Further, the cobble or scree are fixed with iron pipe, and steel plate water stopper is connected on iron pipe, passes through spiral shell on iron pipe
Line is connect with flow cavitation result valve, is provided with frame column above cobble or scree.
In conclusion advantages of the present invention and good effect are as follows:
Anti- buoyancy force of underground water is removed without external force, takes measures to reduce external water buoyancy.Need external force that anti-power is gone also to subtract
Small, the quantity of the corresponding anti-float anchor rod for reducing basement or the counterweight for reducing basement anti-floating reduce the anti-of underground structure
Floating project cost.
