Abstract
A kind of deep basal pit underground space structure of the present invention, including：Foundation ditch, the foundation ditch is drum-shaped；Some pile bodies, are circular layout along the crater wall of foundation ditch, and are mutually twisted together, form circumferentially closed barricade；Inner support structure, is circular layout along barricade inwall, and support is formed to the barricade from the inside of foundation ditch to the soil body；The bottom of the pile body is supported on the bottom surface of the foundation ditch.Using this design, be by pile body as just block body medium, pile body does not produce reaction force to absorb the lateral pressure that the soil body of an outside applies pile body by the soil body being anchored in below foundation ditch bottom surface in itself, but by the way that the lateral pressure is passed into inner support ring beam, more lateral pressures are undertaken by inner support structure, " supportting weak stake by force " effect is reached.The material required for the lateral pressure of the soil body is absorbed by setting up inner support ring beam few more than the material required for the part that pile body is inserted to foundation ditch.
Description
Technical field
The present invention relates to foundation pit supporting construction and construction method, and in particular to a kind of deep basal pit underground space structure and its applies
Work method.
Background technology
At present, with the development of society, urban land resource is more and more rare, building can not meet people more than ground
When demand, increasing underground space utilization demand is may result in, the current underground space is wanted to expand utilization rate, only
It can be the horizontal expansion region of its own, or longitudinally increase the depth of the underground space, in modern city, horizontal expansion underground
The region in space is clearly unlikely, can influence other urban architectures, and this depth for allowing for longitudinally increasing the underground space is obtained
To the concern of increasing building scholars.At present, most deep basal pits is both designed to square, or irregular shape,
During being constructed to the underground space, when particularly carrying out the construction of deep basal pit barricade, although the barricade having is employed
Interlocking pile design to realize earth-retaining and the purpose of sealing simultaneously, however, the earth-retaining for realizing deep basal pit is ensured that, anchor pole warp
Often be used, to strengthen the earth-retaining anti-pressure ability of pile body, the pressure of the deeper soil body of foundation ditch it is bigger, it is necessary to the anchor pole used more
It is many, or, the pile body for making barricade can be all changed into concrete pile body, to improve fold resistance, however, both approaches are all
Higher cost can be caused, furthermore, the degree of packing of its occlusion of the design of above-mentioned interlocking pile barricade when pile body is poured just
Determine, once the degree of packing goes wrong, the later stage is difficult to change, so as to water-stagnating effect can be caused not good.Chinese patent literature
CN103726496A discloses a kind of circular deep foundation ditch hole-drilling interlocking pile supporting and applies formula method, it is proposed that replaced using Circular Pit
Square foundation ditch, is coordinated to realize gear using the occlusion pile body and ring lining structure that are inserted into bottom of foundation ditch and are circular layout
Soil and sealing.Obtained in order that obtaining barricade than larger earth-retaining ability, those skilled in the art would generally use following several sides
Method：1st, increase the diameter of pile body, 2, muscle quantity in increase, 3, increase pile body insert the depth of pile body, 4, increase the quantity of liner
Or diameter；In fact, increase pile body diameter and interior muscle quantity are to improve pile body fold resistance, it is not broken or bending in pile body
In the case of, really play mainly above-mentioned third and fourth way for improving earth-retaining ability.Either use in the prior art
3rd or the 4th way, all it is built upon under the premise of one kind, that is, pile body inserts the soil body of bottom of foundation ditch, with pile body
Main earth-retaining power is provided, and has been Auxiliary support effect using inner lining structure.However, in order to improve identical earth-retaining energy
Increase inner lining structure institute will be far longer than by increasing the material of body of a pile used required for power, the pile body depth that the soil body is inserted by increasing
The material needed to use.Therefore, pile body is inserted into the barrier wall structure below the bottom of foundation ditch soil body in the prior art, is a kind of consumption
