Abstract
The utility model discloses a kind of composite pile, pile body top is steel pipe pile, and the bottom of pile body is prestress high intensity concrete stake, and steel pipe pile is fixed with prestress high intensity concrete stake and is connected.The steel pipe pile on pile body top welds with the prestress high intensity concrete stake of pile body bottom.Beneficial effect: novel structure, has given full play to material property, has saved material, has reduced engineering cost.Shown by field trial, this composite pile security performance is good.
Description
Technical field
The utility model relates to a kind of stake, particularly a kind of composite pile.
Background technology
At present, along with expanding economy and social progress, port and pier and high level, super highrise building emerge in large numbers like the mushrooms after rain, and this has higher requirement to pile foundation.Pile foundation is not only born vertical load but also can be born the moment of flexure produced because of horizontal loading.As a kind of important pile base model, steel pipe pile can bear vertical load also can play the characteristic of the good anti-bending strength of steel to bearing capacity of improving the standard.Under horizontal loads, the moment of flexure of pile foundation die-offs from top to bottom along the degree of depth, and maximal bending moment position occurs in the top of stake.If whole pile body is all steel pipe piles, the bottom of pile body need not be born larger moment of flexure and bring larger waste, substantially increases the construction cost of engineering.
Summary of the invention
The purpose of this utility model larger waste in use can occur increases the problem of engineering cost and a kind of composite pile of providing to solve existing steel pipe pile.
The pile body top of the composite pile that the utility model provides is steel pipe pile, and the bottom of pile body is prestress high intensity concrete stake, and steel pipe pile is fixed with prestress high intensity concrete stake and is connected.
The steel pipe pile on pile body top welds with the prestress high intensity concrete stake of pile body bottom.
Use principle of the present utility model:
According to the rule that the moment of flexure of pile foundation under horizontal loads die-offs from top to bottom along the degree of depth, by the upper design of stake be the good steel pipe pile of anti-bending strength and the bottom prestress high intensity concrete stake that to be anti-bending strength more weak, select suitable position to be coupled together by modes such as welding.Shown by field trial, this composite pile has given full play to material property, especially has outstanding performance in horizontal bearing capacity, and different materials pile-type connecting portion is functional.
The beneficial effects of the utility model:
Novel structure, has given full play to material property, has saved material, has reduced engineering cost.Shown by field trial, this composite pile security performance is good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
1, steel pipe pile 2, prestress high intensity concrete stake.
Detailed description of the invention
Refer to shown in Fig. 1:
The pile body top of the composite pile that the utility model provides is steel pipe pile 1, and the bottom of pile body is prestress high intensity concrete stake 2, and steel pipe pile 1 is fixed with prestress high intensity concrete stake 2 and is connected.
The steel pipe pile 1 on pile body top welds with the prestress high intensity concrete stake 2 of pile body bottom.
Use principle of the present utility model:
According to the rule that the moment of flexure of pile foundation under horizontal loads die-offs from top to bottom along the degree of depth, by the upper design of stake be the good steel pipe pile 1 of anti-bending strength and the bottom prestress high intensity concrete stake 2 that to be anti-bending strength more weak, select suitable position to be coupled together by modes such as welding.Shown by field trial, this composite pile has given full play to material property, especially has outstanding performance in horizontal bearing capacity, and different materials pile-type connecting portion is functional.
