Abstract

This utility model discloses a flow guiding and water draining structure in a deep foundation pit, relating to the field of engineering constructions, specifically to flow guiding and water draining construction technology in a deep foundation pit; the flow guiding and water draining structure disclosed by this utility model comprises water draining blind ditches and water collecting wells, wherein the water draining blind ditches are arranged below a back casting zone and arranged in an inner circumferential side of a shear wall of a peripheral basement respectively; intersection points of the water draining blind ditches are provided with the water collecting wells; according to the water draining structure disclosed by this utility model, accumulated sedimentation of a building is controlled within 30mm without uneven sedimentation or serious potential safety hazards; all basements are not leaked, thus, the structure disclosed by this utility model is accorded with a demand of safety production.

Description

Drainage discharge structure in the deep foundation ditch
Technical field
The utility model relates to the engineering construction field, especially drainage in the deep foundation ditch, drainage construction technology.
Background technology
In the building construction of drainage in deep foundation ditch, draining, if engineering is positioned at the area that building is concentrated, the job location surrounding building is more; Then under the deep situation of job location foundation depth; Do not possess and adopt the conventional drainage and construction method that falls, if, will cause sinking of ground because adopted the conventional drainage construction that falls; Make the ground building settlement that sink, thereby cause the generation of security incident.Therefore, for exempting the surrounding enviroment influence and satisfying construction requirement, need solve drainage, the drainage problem in the deep foundation ditch with specific construction technology.
Summary of the invention
The utility model job location to be solved surrounding building more for a long time; If adopted the conventional drainage construction that falls; Will cause sinking of ground, make the ground building settlement that sink, thereby cause the problem of the generation of security incident; A kind of drainage in the job location surrounding building deep foundation ditch more for a long time, discharge structure of being suitable for is provided, and this structure is guaranteed the problem of basic concrete quality, environmental protection.
Drainage discharge structure in the deep foundation ditch of the utility model is characterized in that comprising weeper drain and collecting well, and weeper drain is separately positioned on below, ater-casting and peripheral basement shear wall inner rim, and the weeper drain interface point is provided with collecting well.
Described weeper drain is to be filled by third kind of stone of 50~100mm, spreads one deck Dense mesh screen above that as forming at a distance from sand bed.On the draining blind shaft the more square one-tenth of backfill secretly put drainage channel.This blind shaft is so that the not infiltration of closed period of underground water during the pump drainage foundation construction and ater-casting.
Third kind of stone packed height of described weeper drain is 50cm, and width is 50~70cm.
Retaining wall seepage part and base plate seep water in a large number and a little can take to concentrate water conservancy diversion in the ponding well with many plastic pipes around the foundation ditch.The uninterrupted pump drainage of concentrating recharges, and guarantees that falling draining can not cause security implication to the foundation ditch retaining wall, simultaneously to the retaining wall shape observation of fissioning, guarantees that sole plate construction period does not produce seeping phenomenon.Guarantee the smooth implementation of base concrete pouring quality and engineering.
Adopt the discharge structure of the utility model, building adds up settlement Control in 30mm, and differential settlement and major safety risks do not occur; None seepage of basement, engineering is accomplished according to the requirement of Construction unit, designing unit smoothly, has not only guaranteed the quality and the progress of engineering; Effectively controlled engineering cost; And improved the construction technology level, and to have controlled preferably with the influence of construction neighboring buildings and resident, the economic security effect is good.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the utility model embodiment 1 section structure sketch map.
Wherein, weeper drain 1, collecting well 2, ater-casting 3.Basement shear wall 4.
The specific embodiment
Embodiment 1: drainage in the deep foundation ditch, discharge structure, and weeper drain 1 is set below building ater-casting 3, and is peripherally descending chamber shear wall 4 inner rims that weeper drain 1 is set, weeper drain 1 interface point is provided with collecting well 2.Weeper drain 1 is filled third kind of stone of 50~100mm, and packed height is 50cm, and width is 50cm, spreads one deck Dense mesh screen above that as separated sand bed, and the square one-tenth of backfill is secretly put drainage channel more afterwards.
