Abstract
The utility model discloses a super-giant foundation pit skirt-rim supporting structure, which is a last support of a foundation pit and characterized by comprising a skirt-rim support arranged around the foundation pit. One end of the skirt-rim support is fixedly connected with a central area baseboard, and the other end of the skirt-rim support is fixed on an underground diaphragm wall through an enclosing purlin. Through an optimal design of a bracing of the foundation pit, after the last support but one is finished, and under a working condition that earth is retained to protect a slope around the foundation pit, earth in a central area is excavated to the bottom of the foundation pit, and then the support of the central area baseboard and the skirt-rim support are replaced, finally, the rest earth is excavated to the bottom of the foundation pit, and constructions of surrounding baseboards are finished. The super-giant foundation pit skirt-rim supporting structure can greatly reduce construction cost, increase speed of earth excavation and speed of baseboard formation, reduce maintenance time of the support and shorten construction cycle of an underground structure.
Description
Technical field
The utility model belongs to the Civil Engineering Construction technical field, relates to a kind of foundation ditch supporting form, specifically a kind of shirt rim, last road braced structures of ultra-large type foundation ditch.
Background technology
In the building construction process, important construction link during the excavation of foundation ditch.During excavation of foundation pit, need provide a rational support system to foundation ditch, thus the excavation work that guarantees foundation ditch can carry out safely and effectively, therefore, the key that to set up a rational bracing of foundation pit system be excavation of foundation pit work plays an important role to construction cost and construction period.Supporting for the last road of ultra-large type foundation ditch at present generally adopts full hall to arrange, can satisfy the requirement that foundation ditch supports though adopt full hall to support, but have the construction cost height, it is slower to support curing time length and shoveling and base plate formation speed, shortcomings such as underground structure long construction period.
The utility model content
Technical problem to be solved in the utility model provides a kind of construction cost, quickening shoveling and base plate of can reducing and forms speed, and can reduce the support curing time, shorten the ultra-large type foundation ditch shirt rim braced structures of underground structure construction period, to overcome the above-mentioned defective that prior art exists.
A kind of ultra-large type foundation ditch shirt rim braced structures, it is that the last road of foundation ditch supports, and it is characterized in that, comprises along the shirt rim that the foundation ditch periphery is provided with and supporting, and described shirt rim is supported an end and is fixedlyed connected with the central area base plate, and the other end is fixed on the diaphragm wall by enclosing purlin.
By above disclosed technical scheme as can be known, the utility model passes through the bracing of foundation pit optimal design, after in the end second way supports and finishes, stay under the native bank protection operating mode at the foundation ditch periphery, central excavation zone cubic metre of earth is at the bottom of the foundation ditch, constructing then, central area base plate and shirt rim are supported, support replacement, excavate peripheral surplus earth at last at the bottom of the foundation ditch, and finish peripheral base plate and construct, by ultra-large type foundation ditch shirt rim braced structures, can reduce construction cost greatly, accelerate to cut the earth and base plate formation speed, reduce and support curing time, shorten the underground structure construction period.
Description of drawings
Fig. 1 is the utility model ultra-large type foundation ditch shirt rim support node structural representation.
Fig. 2 is the utility model ultra-large type foundation ditch shirt rim support arrangement figure.
Reference numeral is as follows:
1, the shirt rim is supported 2, central area base plate 3, is enclosed purlin
4, diaphragm wall 5, support bracket 6, upward support together
7, bed course
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As described in Fig. 1, Fig. 2, the utility model ultra-large type foundation ditch shirt rim braced structures, it is that the last road of foundation ditch supports, and comprises along the shirt rim that the foundation ditch periphery is provided with supporting 1, described shirt rim is supported 1 one ends and is fixedlyed connected with central area base plate 2, and the other end is fixed on the diaphragm wall 4 by enclosing purlin 3.
Described shirt rim support 1 is fixedlyed connected with central area base plate 2 by supporting bracket 5.
The above is a better embodiment of the present utility model only, is not to be used for limiting protection domain of the present utility model, and every equal conversion of being done according to the utility model claim is all within protection domain of the present utility model.
