Abstract

The utility model relates to the technical field of geotechnical engineering, particularly relates to the technical field of a precast high strength concrete thin-wall steel pipe pile foundation pit supporting structure, and provides a precast high strength concrete thin-wall steel pipe pile foundation pit supporting structure which comprises precast high strength concrete thin-wall steel pipe piles used for blocking soil in foundation pits, three-axis cement soil mixing piles used for stopping water in the foundation pits and foundation pit inner soil bodies. The precast high strength concrete thin-wall steel pipe piles and the three-axis cement soil mixing piles are respectively arranged on the upper portion of the foundation pit inner soil bodies. The precast high strength concrete thin-wall steel pipe pile foundation pit supporting structure can be recycled and is applied to the excavation of the foundation pits with a deeper depth, and functions of large structural stiffness, soil-blocking and water-stopping are achieved.

Description

A kind of prefabricated high-strength concrete thin-wall steel tube pile pit supporting construction
Technical field
The utility model relates to the geotechnical engineering technical field, especially relates to a kind of technical field of prefabricated high-strength concrete thin-wall steel tube pile pit supporting construction.
Background technology
It is a kind of compound retaining soil waterproof structure that shaped steel forms that in the triaxial cement mixing pile of socket continuously, inserts that the shaped steel cement-soil stirs wall.This structure has that technology is simple, pile-forming speed is fast, and fender body takes up room little, and it is little to surrounding environment influence to construct, and the body of wall barrier performance is good, and shaped steel is recyclable, advantages such as environmental protection and energy saving.But it is less relatively that the shaped steel cement-soil stirs the rigidity of wall, be out of shape greatlyyer, in the engineering that surrounding enviroment protection is had relatively high expectations, should not select for use.Comparatively responsive when the foundation ditch surrounding enviroment to underground SEA LEVEL VARIATION, when major part is the stronger soil layer of water permeability such as sand (powder) property soil in the agitation pile pile body scope, answer careful in selecting.
Summary of the invention
The utility model purpose provide a kind of rigidity of structure big, have retaining native sealing function, reusable edible concurrently, be applicable to the prefabricated high-strength concrete thin-wall steel tube pile pit supporting construction of cutting depth than deep foundation ditch.
A kind of prefabricated high-strength concrete thin-wall steel tube pile pit supporting construction; Comprise the prefabricated high-strength concrete thin steel pipe pile that is used for foundation ditch retaining soil, the triaxial cement mixing pile that is used for the foundation ditch sealing, the inner soil body of foundation ditch, arrange prefabricated high-strength concrete thin steel pipe pile, triaxial cement mixing pile respectively on the top of the inner soil body of foundation ditch.
Interlaced arrangement between the prefabricated high-strength concrete thin steel pipe pile of the utility model, the triaxial cement mixing pile.
The utility model adopts technique scheme; Compared with prior art have following advantage: the utility model adopts prefabricated high-strength concrete thin-wall steel tube pile pit supporting construction; Can give full play to the advantage of prefabricated high-strength concrete thin steel pipe pile; It is big to stir wall form structure rigidity than shaped steel cement-soil, and bending resistance is strong, and malformation is little.Prefabricated high-strength concrete thin steel pipe pile is meant that adopting the trade mark be steel plate (steel band) fluid concrete in the steel pipe that the cans welding is processed of Q235B or Q345B; Through centrifugal forming; Concrete crushing strength is not less than 80MPa, has the foundation pile goods that bear big vertical load and horizontal loading.Prefabricated high-strength concrete thin steel pipe pile is inserted in the triaxial cement mixing pile, and this combining structure can be brought into play the double effects of retaining soil and sealing in underground construction, be a kind of desirable foundation pit supporting construction.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
The specific embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to the utility model:
As shown in Figure 1; A kind of prefabricated high-strength concrete thin-wall steel tube pile pit supporting construction; Comprise the prefabricated high-strength concrete thin steel pipe pile 1 that is used for foundation ditch retaining soil, the triaxial cement mixing pile 2 that is used for the foundation ditch sealing, the inner soil body 3 of foundation ditch, arrange prefabricated high-strength concrete thin steel pipe pile 1, triaxial cement mixing pile 2 on the top of the inner soil body 3 of foundation ditch respectively.
As shown in Figure 1, interlaced arrangement between the prefabricated high-strength concrete thin steel pipe pile 1 of the utility model, the triaxial cement mixing pile 2.
Job practices based on the prefabricated high-strength concrete thin-wall steel tube pile pit supporting construction of the utility model may further comprise the steps:
The first step: according to site condition and computational analysis, confirm model, long, the pile spacing of stake of prefabricated high-strength concrete thin steel pipe pile 1, confirm stake footpath, long, the pile spacing of stake of triaxial cement mixing pile 2;
Second step: construction triaxial cement mixing pile 2;
The 3rd step: vertically lift by crane high-strength concrete thin steel pipe pile 2, be inserted in the triaxial cement mixing pile 1, construct to projected depth;
The 4th step: the inner soil body of excavation pit, construction support system;
The 5th step:, build bed course, construction base plate and agent structure to clearing up, flatten in the end, foundation ditch hole;
The 6th step: backfill, extract prefabricated high-strength concrete thin steel pipe pile according to circumstances.
The utility model adopts technique scheme; Compared with prior art have following advantage: the utility model adopts prefabricated high-strength concrete thin-wall steel tube pile pit supporting construction; Can give full play to the advantage of this structure; It is big to stir wall form structure rigidity than shaped steel cement-soil, and bending resistance is strong, and malformation is little.
