Abstract
The invention discloses a building elevator shaft bottom precipitation construction method which comprises the following steps: digging a sump in an elevator shaft, pre-burying metal tubes in the sump, filling cobblestones into the sump to reach the standard height of a bedding, fixing the metal tubes in the sump, adopting a self-priming pump to work, casting a concrete bedding while pumping water, paving waterproof coiled materials , carrying out construction operation of a concrete protective layer, and carrying out construction operation of foundation slabs. The building elevator shaft bottom precipitation construction method can effectively overcome the practical difficulty that due to the fact that water is too much in the elevator shaft, the next process cannot be carried out, ensures normal construction of the bedding and effectively prevents the waterproof roll from protruding out of the foundation bottom due to the water.
Description
Technical field
The present invention relates to a kind of architecture construction method, specifically, relate to a kind of building elevator shaft bottom dewatering construction method.
Background technology
During building foundation construction at present, due to turning one's coat of underground water, it is too much that ponding often appears in elevator shaft, and cause elevator shaft can't carry out the construction of concrete cushion and waterproof roll paving operation, if construction cushion coat and laying water-proof coiled material by force, waterproof roll is easily gone out backplate surface by drum.
On the building site, precipitation all uses foundation ditch perimeter well point dewatering at present, and the method can be controlled foundation ditch water level inside absolute altitude.But there is following defective in the method: the elevator shaft elevation of bottom is all in the foundation ditch bottom; along with increasing of floor; the elevator shaft degree of depth also increases relatively; therefore be easy to occur the phenomenon that the elevator shaft internal water accumulation too much can't drain; therefore can cause very large difficulty to cushion construction; if water is drained and construction cushion coat and waterproof roll by force, waterproof roll can occur and be gone out backplate surface by drum, and the phenomenon that the fish tail and waterproof layer top is split.Therefore the construction of next procedure caused certain difficulty.
Summary of the invention
For above-mentioned deficiency of the prior art, the present invention effectively stops waterproof roll and is gone out backplate surface by drum, cause elevator shaft bottom can't carry out the technical barrier of the construction of concrete cushion and waterproof roll paving operation, and a kind of building elevator shaft bottom dewatering construction method is provided.
The technical solution used in the present invention is:
A kind of building elevator shaft bottom dewatering construction method, the method comprises the steps:
A. elevator shaft bottom is dug 1m～1.2m downwards, make base diameter 500mm～700mm, the sump of top diameter 700mm～900mm; Built-in metal pipe in sump, described metal tube diameter 80mm～120mm;
B. backfill stone in sump, be backfilled to the bed course absolute altitude, and metal tube be fixed in sump;
C. adopt the self prime pump operation of drawing water, the ponding in sump is extracted out, and the Pouring concrete at the same time bed course that is drawing water; Laying water-proof coiled material; In waterproof roll and metal tube junction, use waterproofing unction that metal tube is sealed;
D. carry out the concrete cover construction operation;
E. carry out the sole plate construction operation;
F. metal tube is provided with the annulus seal plate at the sole plate layer:
G. cut off metal tube; The metal tube shutoff is closely knit.
Described metal tube root is provided with the circular hole of diameter 10mm～20mm.
The diameter of the particle of described backfill stone is: 20mm～40mm.
Described metal tube shutoff is that spunyarn and asbestos cement are filled in metal tube, then uses the micro-expansion cement sealing; Perhaps use metal sheet that the metal mouth of pipe is welded and carry out shutoff.
Described annulus seal plate is at least twice.
Described annulus seal plate is arranged on sole plate layer centre position.
The thickness of described annulus seal plate is 3mm～8mm; External diameter 150mm～180mm.
Described annulus seal plate is that welding can be also to weld in advance when construction.
Described metal tube lower end is 1/4th of sump overall height apart from the height of sump bottom.The beneficial effect of the relative prior art of the present invention:
Building elevator shaft bottom dewatering construction method of the present invention can effectively be controlled the practical difficulty that can't carry out next procedure that elevator shaft internal cause ponding too much brings to construction; Guaranteed the normal construction of bed course; Prevent that effectively waterproof roll from bloating foundation bed because of ponding.
