Description
Technical Field
The utility model relates to a dedicated stake of foundation engineering, in particular to cavity steel supporting construction device in ultra-deep foundation ditch can have enough to meet need.
Background
The foundation pit is an earth pit excavated at the design position of the foundation according to the elevation of the foundation and the plane size of the foundation, and the foundation pit engineering mainly comprises the design and construction of a foundation pit supporting system and the excavation of earth, so that the foundation pit is a system engineering with strong comprehensiveness. In the foundation pit engineering, an underground space is excavated downwards from the ground, and in order to ensure the stability of the foundation pit engineering and prevent water and sandy soil from entering the foundation pit, a supporting structure is generally arranged around the pit wall of the foundation pit. In the excavation and supporting of a foundation pit, the design of a foundation pit supporting structure directly influences the quality, efficiency and cost of engineering.
The existing foundation pit supporting structure mainly adopts a mode of cofferdam of cast-in-place reinforced concrete and steel sheet piles, and the mode of the cast-in-place reinforced concrete has the advantages of high supporting strength, small deformation, safety and reliability, but has the main defects of long construction period, difficult demolition, no repeated use of materials and higher cost; the mode that adopts steel sheet pile cofferdam has that the installation is dismantled conveniently, repeatedly usable, advantage that the cost is lower, and the cross section of present steel sheet pile has the fore shaft for both ends, and one side has the open-ended shape, wherein the most commonly used is U shaped steel sheet pile, however this kind of steel sheet pile's support intensity is low for cause the steel sheet pile to break the bending easily when being used for the support protection in the deep foundation ditch of degree of depth for the foundation ditch is very easily taken place to collapse, has great potential safety hazard.
Disclosure of Invention
The utility model aims to solve the technical problem that a cavity steel supporting construction device in can having enough to meet need super deep foundation ditch is provided, and this kind of cavity steel supporting construction device supports intensity height in can having enough to meet need super deep foundation ditch, can effectively resist the pressure that comes from sand and water to can used repeatedly.
In order to solve the technical problems, the technical scheme is as follows:
cavity steel supporting construction device in can having enough to meet need ultra-deep foundation ditch, its characterized in that: including steel-pipe pile main part and two bar hasp boards, the steel-pipe pile main part has interior cavity, and steel-pipe pile main part both sides are located respectively to two bar hasp boards, and the length direction of bar hasp board is unanimous with the axial of steel-pipe pile main part, and bar hasp inboard border and steel-pipe pile main part outer wall fixed connection, the outside border of bar hasp board are equipped with the fore shaft, and the fore shaft on two bar hasp boards matches each other.
When the turnover ultra-deep foundation pit inner cavity steel supporting structure device is used for constructing an ultra-deep foundation pit cofferdam, the inner cavity steel supporting structure devices are sequentially connected according to needs, locking notches on adjacent sides of the two adjacent inner cavity steel supporting structure devices are connected with each other, and water-stopping materials are adopted for splicing joints, so that cofferdams with various shapes are formed. Because the inner cavity steel supporting structure device takes the steel pipe pile main body as a main component part, the tubular structure has stronger deformation resistance, particularly bending resistance, and more stable structure and higher supporting strength compared with a plate-shaped structure, the inner cavity steel supporting structure device can effectively support the foundation pit wall with deeper depth, and has strong waterproof and sand-proof soil capability and supporting force. After the foundation pit construction is completed, the internal cavity steel supporting structure devices can be disassembled and reused.
Preferably, the inner side edge of the strip-shaped locking plate is integrally connected with the outer wall of the steel pipe pile main body.
The inner side edge of the strip-shaped locking plate can also be connected with the outer wall of the steel pipe pile main body in a welding mode.
In a preferable scheme, the cross section of the steel pipe pile body is circular, regular polygonal (such as regular hexagon), trapezoid (such as isosceles trapezoid) or oval.
The beneficial effects of the utility model reside in that: the cavity steel supporting structure device in the ultra-deep foundation pit can form cofferdams with various shapes according to needs, is high in strength and good in waterproof performance, can effectively resist pressure from sand and water, and can be used repeatedly.

Detailed Description
The invention will be further described with reference to the following drawings and specific embodiments:
example 1
Cavity steel supporting construction device in ultra-deep foundation ditch that can have enough to meet need as shown in fig. 1-2, including steel-pipe pile main part 1 and two bar hasp boards 2, the cross section of steel-pipe pile main part 1 is regular hexagon, steel-pipe pile main part 1 has interior cavity 101, 1 both sides of steel-pipe pile main part are located respectively to two bar hasp boards 2, the length direction of bar hasp board 2 is unanimous with the axial of steel-pipe pile main part 1, 2 inboard borders of bar hasp board and 1 outer wall fixed connection of steel-pipe pile main part, the outside border of bar hasp board 2 is equipped with fore shaft 201, the fore shaft 201 on two bar hasp boards 2 matches each other.
When the turnover ultra-deep foundation pit inner cavity steel supporting structure device is used for constructing an ultra-deep foundation pit cofferdam, the inner cavity steel supporting structure devices are sequentially connected according to needs, the locking notches 201 on the adjacent sides of the two adjacent inner cavity steel supporting structure devices are mutually connected, and water-stopping materials are adopted for the joints to be twisted and sewed, so that cofferdams with various shapes are formed. Because the inner cavity steel supporting structure device takes the steel pipe pile main body 1 as a main component part, the tubular structure has stronger deformation resistance, particularly bending resistance, and more stable structure and higher supporting strength compared with a plate-shaped structure, the inner cavity steel supporting structure device can effectively support the foundation pit wall with deeper depth, and has strong waterproof and sand-proof soil capability and supporting force. After the foundation pit construction is completed, the internal cavity steel supporting structure devices can be disassembled and reused.
