Abstract
Reduce pressure under the utility model discloses a kind of ultra-deep underground space structure base plate drainage system, be characterized in that this decompression drainage system is made up of the inverted filter be arranged under base plate, gutter, collecting well and pumped well, described gutter establishes the webbed drainage pipeline networks of foraminate steel pipe by some; Described collecting well is arranged on the gutter junction of intersecting in length and breadth; Described pumped well is arranged on the outside of drainage pipeline networks and is communicated with collecting well, and underground water confluxes to collecting well by the gutter in inverted filter, is pumped by underground water by pumped well.The utility model compared with prior art has base plate demand of anti-crack low, decompression, anti-floating is effective, while base plate meets anti-floating requirement, can control effectively to the ground settlement of surrounding, greatly reduce the setting of anti-floating pile, structure is simple, easy construction, engineering cost is low, especially adapts to the Anti-floating design of 30m depth underground space structures.
Description
Technical field
The utility model relates to underground structure anti-floating technical field, and 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.
Utility model content
The purpose of this utility model is the drainage system that reduces pressure under a kind of ultra-deep underground space structure base plate designed for the deficiencies in the prior art, 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 utility model object 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 utility model 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.

Detailed description of the invention
Accompanying drawings 1 ~ accompanying drawing 2, the utility model is made up of the rubble inverted filter 1 be arranged under structure base slab 11, gutter 2, collecting well 3 and pumped well 9, described gutter 2 is for being arranged on the steel pipe that in rubble inverted filter 1, some are evenly covered with into water aperture 8, and some gutters 2 are to be connected to form latticed drainage pipeline networks in length and breadth; Described collecting well 3 is arranged on gutter 2 Nodes that outside is connected in length and breadth; Described pumped well 9 be arranged on drainage pipeline networks side and with collecting well 3 one_to_one corresponding, pumped well 9 is communicated with collecting well 3 by gutter 2, and seepage in underground confluxes to collecting well 3 by the gutter 2 in rubble inverted filter 1, pumps drainage pipeline networks by pumped well 9.
Accompanying drawings 3, described collecting well 3 is arranged on the Nodes that rubble inverted filter 1 internal drainage pipe 2 is connected in length and breadth, and the cover plate of collecting well 3 is provided with one way valve 4.Described rubble inverted filter 1 is arranged on structure base slab 11 times, rubble inverted filter 1 is laid waterproof geotextiles 5, and rubble inverted filter lays permeable geotextiles 6 for 1 time.
Accompanying drawings 4 ~ accompanying drawing 5, described gutter 2 is evenly be covered with the steel pipe into water aperture 8, gutter 2 outer wrapping geotechnique anti-filter cloth 7.
The utility model is construction like this; Being excavated to 0.4 ~ 1.0m under the design elevation of structure base slab 11 is bottom, bottom is laid permeable geotextiles 6, then in permeable geotextiles 6, rubble inverted filter 1 is laid, gutter 2 to be arranged in rubble inverted filter 1 and to be connected to form latticed drainage pipeline networks in length and breadth, rubble inverted filter 1 is laid to the design elevation of structure base slab 11, and rubble inverted filter 1 is laid waterproof geotextiles 5.Collecting well 3 is arranged on gutter 2 Nodes that outside is connected in length and breadth.Pumped well 9 be arranged on drainage pipeline networks side and with collecting well 3 one_to_one corresponding, pumped well 9 is communicated with collecting well 3 by gutter 2.Seepage in underground is confluxed to collecting well 3 by the gutter 2 in rubble inverted filter 1 and forms latticed drainage pipeline networks, by pumped well 9, seepage in underground is pumped drainage pipeline networks when the water of collecting well 3 exceedes certain limit, reduce underground water to the uplift pressure of structure base slab 11, structure base slab 11 is made not only to meet anti-floating requirement, and the ground settlement of surrounding environment is also can be controlled in allowed band, greatly reduce the setting of anti-floating pile, especially adapt to the Anti-floating design of 30m depth underground space structures.
More than just be further described the utility model, and be not used to limit this patent, all be the utility model equivalence enforcement, within the right that all should be contained in this patent.
