Abstract
The utility model provides a large-diameter arc-shaped steel sheet pile foundation pit supporting structure, and relates to the technical field of geotechnical engineering, in particular to the technical field of large-diameter arc-shaped steel sheet pile supporting structures. The large-diameter arc-shaped steel sheet pile foundation pit supporting structure structurally comprises large-diameter arc-shaped steel sheet piles (1) used for blocking soil and stopping water, and cemented soil deep mixed piles (2), wherein the large-diameter arc-shaped steel sheet piles (1) are arranged continuously, every two adjacent large-diameter arc-shaped steel sheet piles (1) are connected through connectors, and the connectors are located in the cemented soil deep mixed piles (2) to form the large-diameter arc-shaped steel sheet pile foundation pit supporting structure finally; a plug-in type connector pair is used as each connector, namely one end of the connector is provided with a plug (3) and the other end of the connector is provided with a socket (4). The cemented soil deep mixed piles are used for preventing leakage at the connectors. The large-diameter arc-shaped steel sheet pile foundation pit supporting structure achieves the purposes that the steel sheet piles are wide, lateral rigidity is high, water stopping performance is better, the structural style is simple, the construction speed is high, and the large-diameter arc-shaped steel sheet pile foundation pit supporting structure can be used repeatedly and is suitable for soft soil foundation pit projects with a large cutting depth and a high underground water level.
Description
Technical field
The utility model relates to the Geotechnical Engineering field, relates in particular to a kind of major diameter curved plate pile pit supporting construction technical field.
Background technology
The major function of foundation pit supporting construction is gear soil and sealing, and supporting and protection structure can be divided into cast in situs formula and prefabricated assembled two kinds according to manufacture craft.The foundation pit supporting construction of cast in situs generally refers at the construction field (site), first grooving, lay reinforcing cage, the encapsulating compound gel material forms and possesses some strength again, can bear the structure of lateral earth pressure, water pressure, commonly used have bored pile, a diaphragm wall etc., also has and first carry out Soil-cement, insert again shaped steel, as SMW engineering method stake etc.Cast in situs formula supporting and protection structure has the advantages such as good integrity, rigidity are large, the anti-leakage performance is good, applicable geological conditions is extensive, and that its shortcoming is that job site is polluted is large, construction needs that heavy mechanical equipment, construction technology process are comparatively complicated, the construction period is long, construction costs is more high.
Prefabricated assembled foundation pit supporting construction generally refers to that the supporting barricade completes, and only need assemble at the construction field (site) enforcement and get final product, as steel pipe pile, steel sheet pile etc.This kind of support pattern has the advantages such as job site is pollution-free, construction technology is simple, speed of application is fast, the recyclable recycling of supporting and protection structure.But its shortcoming is also comparatively obvious, the steel pipe pile steel using amount is large, larger to soil disturbance, and endurance and stiffness is less, distortion is larger for steel sheet pile.
Summary of the invention
Technical problem: the purpose of this utility model is to provide that a kind of endurance and stiffness is large, form of structure is simple, job practices is quick, cheap, capable of circulation practicality, have the major diameter curved plate pile pit supporting construction of gear soil and water stopping function concurrently.
Technical scheme: a kind of major diameter curved plate pile pit supporting construction of the present utility model comprises major diameter arc-shaped steel sheet pile, for preventing the cement-soil mixing pile of joint seepage.
This structure comprises for keeping off major diameter arc-shaped steel sheet pile, the cement-soil mixing pile of soil and sealing, wherein, major diameter arc-shaped steel sheet pile continuous arrangement, and adjacent two major diameter arc-shaped steel sheet piles connect by joint, this joint is arranged in cement-soil mixing pile, finally forms a major diameter curved plate pile pit supporting construction.
Described joint adopts bayonet joint pair, and an end is that the plug other end is socket.
Beneficial effect: the utility model adopts above technical scheme, possesses compared with prior art following advantage: major diameter curved plate pile pit supporting construction of the present utility model, large than traditional steel sheet pile width, can reach 800mm～1200mm, and the conventional steel sheet pile is only 300mm～500mm, speed of application is faster; It is more reasonable that arc-shaped sections is transmitted soil pressure than conventional steel sheet pile, and lateral rigidity is larger, can effectively control Supporting Structure deformation; The pin and box sub of major diameter arc-shaped steel sheet pile is placed in cement-soil mixing pile, makes it sealing performance better; Construction on Environment is almost pollution-free, and material is capable of circulation repeatedly to be used.
The accompanying drawing explanation
Fig. 1: major diameter curved plate pile pit supporting construction floor map,
Fig. 2: major diameter curved plate pile pit supporting construction elevational schematic view,
In above figure, have: major diameter arc-shaped steel sheet pile 1; Cement-soil mixing pile 2; Plug 3; Socket 4.
The specific embodiment
Below in conjunction with 1 pair of the technical solution of the utility model of accompanying drawing, be elaborated:
A kind of major diameter curved plate pile pit supporting construction of the present utility model, comprise major diameter arc-shaped steel sheet pile 1, cement-soil mixing pile 2, plug 3, socket 4.
As shown in Figure 1, major diameter arc-shaped steel sheet pile 1 of the present utility model, the plug 3 of employing both sides, socket 4 are in the interior grafting of cement-soil mixing pile 2.Major diameter arc-shaped steel sheet pile continuous arrangement, and adjacent two major diameter arc-shaped steel sheet piles connect by joint, and this joint is arranged in cement-soil mixing pile, finally forms a major diameter curved plate pile pit supporting construction.
The utility model adopts a kind of major diameter curved plate pile pit supporting construction job practices, comprises the steps:
The first step: according to engineering geological conditions and the excavation of foundation pit degree of depth, determine that width, thickness, the stake of major diameter arc-shaped steel sheet pile 1 is long, diameter, the cement mixing content of design cement-soil mixing pile 2;
Second step: construction cement-soil mixing pile 2;
The 3rd step: construction major diameter arc-shaped steel sheet pile 1;
The 4th step: excavation of foundation pit and Underground Construction;
The 5th step: Underground Construction is complete, extracts major diameter arc-shaped steel sheet pile 1.
Claims (2)
