Abstract
The invention relates to a comprehensive waterproof and drainage construction method for a basement exterior wall of a super-high-rise building. A horizontal groove with certain slope is dug along a rock and soil interface of a building basement; a plurality of grooves are dug in the rock wall of the building basement along a vertical crack; a rock stratum drain pipe is placed in the groove, a plurality of drain holes corresponding to the vertical crack are formed in the rock stratum drain pipe, and the horizontal groove is communicated with the upper end of the rock stratum drain pipe; a blind ditch is dug at the bottom of the building basement or the lower rock wall and communicated with the lower end of the rock stratum drain pipe; the blind ditch is communicated with a blind ditch drain pipe erected between an indoor drain ditch and an outdoor drain ditch in a downward inclination manner; and finally, the constructions are sequentially performed on the rock wall of the building basement: cement leveling and constructions of a coiled material waterproof layer, a felt slide layer and a reinforced concrete side wall. According to the method, water resistance and drainage are combined, the construction technology is simple, the construction is convenient, drainage, seepage prevention, dredging and discharging are achieved effectively, and the waterproof effect is good.
Description
Technical field
The present invention relates to a kind of anti-draining comprehensive construction method, is the anti-draining comprehensive construction method of a kind of basement in high rise building exterior wall that transfinites specifically.
Background technology
When the stone regional building construction of mountain; in order effectively to protect the urban operating mechanism of periphery; in conjunction with rock behavio(u)r; its building foundation pit adopts machine cuts, vertical cut technology; on in the crag behind the excavation more vertical crack is arranged; soil layer about two meters is arranged at the top, hole, and the soil layer that contains surface water oozes out through interface and crack.As adopt and prevent water-proofing method in the traditional architecture barricade outside the subsides, interior subsides anti-the infiltration for crag are outward blocked up, are prevented acting on, and in the increase of crag bottom infiltration hydraulic pressure, the bottom waterproof is seepage under influence of hydraulic pressure easily.
Summary of the invention
In in the prior art, paste the deficiency that the bottom hydraulic pressure increase that exists in the outer anti-water-proofing method influences waterproof effect, the invention provides simple, the easy construction of a kind of technology, to crag infiltration effective drainage, antiseepage, white-out, the anti-draining comprehensive construction method of the basement in high rise building exterior wall that transfinites of good water-proof effect.
The technical solution used in the present invention is: the anti-draining comprehensive construction method of a kind of basement in high rise building exterior wall that transfinites, and it may further comprise the steps:
(1) dig the level trough of band certain slope along building basement rock, native interface, the level trough groove up;
(2) dig a plurality of grooves in building vertical crack, basement crag upper edge, place the rock stratum gutter in the groove, offer the drain hole in the vertical crack of a plurality of correspondences on the gutter of rock stratum, level trough is communicated with gutter upper end, rock stratum;
(3) in building basement bottom or the bottom crag dig and be with a french drain, french drain is communicated with gutter lower end, rock stratum;
(4) have a down dip between french drain and gutter, indoor and outdoor and set up the blind drainage pipe and be communicated with;
(5) finally construction successively on building basement crag: cement levelling, coil waterproof layer, malthoid sliding layer, steel concrete sidewall.
Further, fill full cobble in described level trough, the french drain.
Again further, establish filter core in the gutter of described rock stratum; The described blind drainage pipe mouth of pipe arranges filter bowl.
Adopt above technical scheme, the invention has the beneficial effects as follows:
1, rock, native interface are offered level trough, collect the part of seeping water down in the earth on the rock by the level trough groove; The rock stratum gutter corresponding with vertical crack is set on the crag, collects in the crag infiltration part down by the corresponding vertical crack of drain hole of rock stratum gutter; The crag bottom arranges the french drain that is communicated with the rock stratum gutter, infiltration part under unified collection earth, the crag, and will descend infiltration part to concentrate by the blind drainage pipe to drain in the gutter of indoor or outdoors, play drainage, white-out effect, effectively avoid the concentrated water leakage that causes of bottom seepage pressure;
2, establish filter core in the gutter of rock stratum, the blind drainage pipe mouth of pipe arranges filter bowl, can effectively filter the sandy soil in the infiltration, prevents line clogging; Guanovulite in the level trough, french drain, when the follow-up levelling waterproofing work of crag, the trough structure is filled solidly on the crag, can effectively guarantee crag safety and levelling quality, plays the infiltration preliminary filtering function simultaneously.
The present invention offers level trough and french drain respectively in the crag upper and lower part, and offer the rock stratum gutter that is communicated with level trough and french drain respectively along the vertical crack of crag, realize the drainage of earth infiltration in the level trough, crag infiltration, following row by the rock stratum gutter, discharged by the blind drainage pipe by french drain, cooperate follow-up levelling and waterproofing work on the crag, realize anti-, draining combination, its construction technology is simple, easy construction, effective drainage, antiseepage, white-out, good water-proof effect.
