Description

Internal support of foundation pit pile for prestressed pipe vertical supporting structure
Technical field
This utility model is related to the technical field of foundation ditch supporting construction, and particularly internal support of foundation pit pile for prestressed pipe vertically props up Support structure.
Background technology
Deep foundation pit support is guarantee that foundation ditch is stable, often uses inner support supporting construction, inner support supporting construction one As be made up of support pile, vertical supporting post and horizontal inner support beam.The vertical supporting post commonly used at present is formed steel construction column, leads to Crossing the bored concrete pile of certain depth of constructing before excavation of foundation pit to hole, to play wedge action (be empty stake in the range of foundation depth Hole), then enter in bored concrete pile tip cutting and fixedly mount the steel structure column of Site Welding making, this form of construction work operation is various, Rolled steel dosage is big, and the sidewall stability of empty stake holes affects the perpendicularity of steel structure column, and the company of bored concrete pile and steel structure column Connect construction and the field fabrication quality of steel structure column all can directly influence the supporting role of steel structure column, thus having influence on whole The stability of individual inner support system system and supporting effect.
Utility model content
The purpose of this utility model is to overcome the shortcoming of existing inner support steel structure support column, provides a kind of minimizing construction work Sequence, rolled steel dosage 40% can be saved, improve foundation ditch support strength, shorten construction period, keep the stable internal support of foundation pit of foundation ditch pre- Stress pile tube vertical supporting structure.
The purpose of this utility model is achieved through the following technical solutions:Internal support of foundation pit pile for prestressed pipe vertical supporting is tied Structure, it includes foundation ditch, support pile, pile for prestressed pipe vertical supporting post and inner support, and the edge of excavation slope is provided with a row and props up Fender pile, is provided with least one row and inner support opposed pile for prestressed pipe vertical supporting post in foundation ditch, pile for prestressed pipe is vertical Support column is made up of the prefabricated tubular pile that more piece is sequentially connected with, and every two adjacent sections prefabricated tubular pile is all connected by splicing device, prestressing force It is provided with multiple tracks inner support between the support pile that pile tube vertical supporting post stands corresponding thereto.
Described support pile and all vertical setting of pile for prestressed pipe vertical supporting post.
The cross section of described pile for prestressed pipe vertical supporting post is circular or rectangle or abnormal shape.
Described identical length of often section prefabricated tubular pile etc..
Described often section prefabricated tubular pile is fixedly connected by equal diameter splicing device.
The quantity of the described inner support between support pile and pile for prestressed pipe vertical supporting post is twice.
The two ends of described inner support are all fixedly connected with support pile and pile for prestressed pipe vertical supporting post by built-in fitting.
This utility model has advantages below:
1)This utility model utilizes prefabricated tubular pile to substitute the steel lattice column of field fabrication, convenient and swift.
2)This utility model strengthens tubular pile splicing effect and stability using equal diameter splicing device.
3)Pile tube can directly be sink to the supporting course required for supporting, thus effectively reducing the one-tenth of steel structure column bottom bored concrete pile Operation and the material usages such as hole, installation, cast concrete, shorten construction period.
4)Pile tube substitutes steel pile and can save rolled steel dosage 40%, saves vertical supporting post expense 30%.
5)Shorten support system construction period.
