Description
Technical field
The utility model relates to the technical fields of pattern foundation pit supporting structure at basement height difference in Construction of Basement by stages, refer in particular to
A kind of support system.
Background technique
With China's rapid economic development, real estate development of the city project is increasing.Since development of real estate is related to Pang
Big capital chain, real estate sale prospect are difficult to predict, it is however generally that, development of real estate construction carries out by stages according to architectural design
Exploitation, and development progress is adjusted according to market sale situation.From the angle of Base foundation design, when there are different layers for architectural design
When several basements, theoretically should first construct the deeper part of embedded depth of foundation, and corresponding basement foundation ditch also should first construct
Deep foundation pit, then shallow foundation pit of constructing.It is general first when real estate project is developed but based on the considerations of aforementioned fund and market
It constructs shallower basement, the deep basement of rear construction.The sequence of this exploitation is high for the basement in different development phases
Foundation Pit Support Design at difference proposes challenge.On the one hand, construction space is limited at basement height difference by stages, Design of Main Structure
A series of problems, such as need to considering intensity, the construction joint setting, waterproof of new-old concrete handover, if the position of seam is design of foundation pit increasing
Big difficulty；On the other hand, built basement structure part needs strict control foundation pit deformation during excavation of foundation pit,
Prevent a series of engineering problems such as structure safety, base plate leakage caused by coming to nothing because of bottom plate.It is practical new at this especially in soft soil area
Before type, in order to solve above-mentioned two problems, the general support system for using stake support or piled anchor.Stake support body system cost height, work
Phase is long, and pile-anchor system in the construction process easily disturbs the life of substrate local products, when Soft Soil Layer is thicker, in order to meet the anti-of design
Bearing capacity is pulled out, anchoring section need to penetrate Soft Soil Layer, thus cause biggish environmental risk in terms of pattern foundation pit supporting structure and cause very big
Waste.
Utility model content
The purpose of this utility model is to utilize already present basement on the basis of the support system that original piled anchor, stake are supportted
Structure, using etc. for anchor pole by the way of, a kind of the equal for anchor rod support method and support system of basement supporting by stages is provided.
Technical solution adopted by the utility model: a kind of support system, including proposed basement (6) and existing basement
(5), it is equipped with reserved space between the proposed basement (6) and the existing basement (5), is equipped with branch in the reserved space
The top of fender pile (1), the support pile (1) is equipped with crown beam (2), and the crown beam (2) anchors into be equipped with and wait for anchor pole (3), described etc.
It is welded and fixed with existing basement (5) by getting rid of muscle (4) for the other end of anchor pole (3).
Preferably, tubular pole, cast-in-place concrete pile or steel-pipe pile may be selected in the support pile (1).
Preferably, the edge of the support pile (1) builds brick wall (7).
Preferably, construction is equipped with waterproof layer on the outside of the brick wall (7).
Preferably, described wait is made for anchor pole (3) of bar material.
Preferably, the distance of the reserved space is the thickness of brick wall (7) and the sum of the radius of support pile (1).
Compared with prior art, the utility model has the beneficial effects that (1), compared with existing stake support body system, this is practical
It is novel with etc. for anchor pole substitute support provide support pile need fulcrum power, save a large amount of backing materials, cost can be greatly reduced,
The process for removing support is also saved simultaneously；Under no supporting condition, the difficulty of earth excavation can be reduced, is shortened the construction period；(2) this reality
The fulcrum power that support pile needs is transferred to for anchor pole with novel use etc. and is provided by existing basement, anchor cable construction process is reduced
In to the emptying of existing basement substrate soil, disturb, reduce the risk of existing structure sedimentation and deformation, avoid sinking to leading because of substrate soil
Cause the risk of basement bottom board cracking, leakage；Using etc. for anchor pole compared with anchor cable, eliminate anchor cable and need time for conserving,
It can effectively shorten the duration；In soft clay area, the anchor cable of overlength can be saved, project cost is effectively reduced；(3) the utility model combines
Outer wall of basement uses the construction technology of unilateral formwork, and in the present invention, the occupied space of support system is small, waits for anchor
In the concrete structure that bar can be embedded to when pouring basement side wall and floorslab concrete, main structure post-cast strip may be disposed at hat
Back portion, thus the quantity of structural joint can be effectively reduced, improve the globality of concrete structure.
