Abstract

The invention discloses a pressure reduction and water drainage system under an ultra-deep underground space structure bottom plate. The pressure reduction and water drainage system is characterized by being composed of an inverted filter, water drainage pipes, water collection wells and pumping wells, the inverted filter, the water drainage pipes, the water collection wells and the pumping wells are arranged below the bottom plate, and the water drainage pipes form a mesh-shaped water drainage pipe network through a plurality of steel pipes provided with small holes; the water collection wells are arranged at the joints of the water drainage pipes which are longitudinally and transversely intersected; the pumping wells are arranged outside the water drainage pipes and communicated with the water collection wells; underground water is converged to the water collection wells from the drainage pipes in the inverted filter and is pumped out through the pumping wells. Compared with the prior art, the requirement for the anti-crack performance of the bottom plate is low, the pressure reduction effect and the anti-floating effect are good, the surrounding ground surface settlement can be effectively controlled while the bottom plate meets the anti-floating requirement, the number of anti-floating piles which are arranged is greatly decreased, the structure is simple, construction is convenient, the engineering cost is low, and the pressure reduction and water drainage system is particularly suitable for the anti-floating design of an underground space structure which is 30 m deep.

Description

Reduce pressure under a kind of ultra-deep underground space structure base plate drainage system
Technical field
The present invention relates to underground structure anti-floating technical field, specifically reduce pressure under a kind of ultra-deep underground space structure base plate drainage system.
Background technology
Along with the acceleration of urbanization process, the exploitation of the underground space more and more comes into one's own, for the underground building such as Large Underground Emporium, underground parking garage, the uplift pressure that its basement bottom board produces due to underground water and surface water infiltration, anti-floating also becomes the emphasis in engineering design.
At present, measure of anti float in underground construction mainly adopts and arrange anti-float anchor rod and anti-floating pile under base plate, by increase underground structure covering weight or establishing anti-float anchor rod, uplift pile balance buoyancy force of underground water, the method structure stress is reasonable, later maintenance is simple, convenient, but engineering cost drops into comparatively large, and require higher to structure cracking resistance, antifatigue.
Summary of the invention
Reduce pressure under the object of the invention is a kind of ultra-deep underground space structure base plate designed for the deficiencies in the prior art drainage system, under adopting structure base slab, sandstone inverted filter and gridding drainage pipeline networks are set, underground water under base plate is collected in collecting well by the drainage pipeline networks being arranged on sandstone inverted filter and pumps, limited reduction seepage in underground is to the uplift pressure of base plate, effect of easing stress is obvious, while meeting the requirement of structure base slab anti-floating, the ground settlement of surrounding environment is also can be controlled in allowed band, structure is simple, low to the demand of anti-crack of base plate, short construction period, economy is high, anti-floating is effective, especially the Anti-floating design of 30m depth underground space structures is adapted to.
The technical scheme realizing the object of the invention is: reduce pressure under a kind of ultra-deep underground space structure base plate drainage system, be characterized in that this decompression drainage system is made up of rubble inverted filter, gutter, collecting well and the pumped well be arranged under ultra-deep structure base slab, described gutter is be arranged on the steel pipe that in rubble inverted filter, some are evenly covered with into water aperture, and some gutters are to be connected to form latticed drainage pipeline networks in length and breadth; Described collecting well is arranged on the gutter junction of intersecting in length and breadth outside drainage pipeline networks; Described pumped well be arranged on drainage pipeline networks side and with collecting well one_to_one corresponding, pumped well is communicated with collecting well by gutter, and seepage in underground confluxes to collecting well by the gutter in rubble inverted filter, pumps drainage pipeline networks by pumped well.
The cover plate of described collecting well is provided with one way valve.
Described rubble inverted filter lays waterproof geotextiles, under rubble inverted filter, lays permeable geotextiles.
Described gutter outer wrapping geotechnique anti-filter cloth.
The present invention compared with prior art has, decompression low to base plate demand of anti-crack, anti-floating is effective, and easy construction, duration are short, operating efficiency is high, engineering cost is low, while meeting the requirement of structure base slab anti-floating, the ground settlement of surrounding environment is also can be controlled in allowed band, greatly reduces the setting of anti-floating pile, especially adapt to the Anti-floating design of 30m depth underground space structures.
