Abstract
A kind of barricade for pattern foundation pit supporting structure of the present invention, wherein, the foundation ditch is drum-shaped, and the barricade includes：Some pile bodies, are circular layout along the crater wall of foundation ditch, and are mutually twisted and together, form circumferentially closed wall；Inner support structure, it is circular layout along wall inwall, support is formed to the wall 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, it is the medium by pile body as just block body, pile body does not produce reaction force to absorb the lateral pressure that the soil body of an outside applies to 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, reach " supportting weak stake by force " effect.It is few more than the material required for the part that pile body is inserted to foundation ditch that the material required for the lateral pressure of the soil body is absorbed by setting up inner support ring beam.
Description
Technical field
The present invention relates to foundation pit supporting construction and construction method, and in particular to a kind of barricade for pattern foundation pit supporting 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 to be less likely, and can influence other urban architectures, this depth for allowing for longitudinally increasing the underground space obtains
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 some barricades employ
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 more, 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 pours just
Determine, once the degree of packing goes wrong, the later stage is difficult to change, so as to which water-stagnating effect can be caused bad.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 is replaced using Circular Pit
Square foundation ditch, coordinated using the occlusion pile body and ring lining structure that are inserted into bottom of foundation ditch and are circular layout to realize gear
Soil and sealing.In order that obtaining barricade obtains bigger earth-retaining ability, those skilled in the art would generally use following several sides
Method：1st, increase pile body diameter, 2, increase in muscle quantity, 3, increase pile body insertion pile body depth, 4, increase liner quantity
Or diameter；In fact, increase pile body diameter and interior muscle quantity simply 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
Power, being inserted by increase required for the pile body depth of the soil body, which increases the material of body of a pile used, will be far longer than increase inner lining structure institute
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
The high barrier wall structure of the more costs of material.
