Abstract
The utility model relates to a latch type steel pipe pile, in particular to a steel pipe pile, which is used for building a bridge pier cofferdam in a deep water channel and is mainly used for solving the problem that a double-wall steel cofferdam is generally used for building the bridge pier cofferdam in the deep water channel. The latch type steel pipe pile is characterized in that a steel plate and a channel steel are welded into a whole. The latch type steel pipe pile is integrally lifted and sunk in the bridge pier construction field. Large lifting equipment is necessary. The construction period is long. The safety monitoring risk is high. Furthermore, the material consumption is high; the cost is high; and the material recovery rate is low. The latch type steel pipe pile comprises a steel pipe. Two semi-U-shaped steel plate piles are welded and fixed on the steel pipe. The bending end of one semi-U-shaped steel plate pile is opposite to the bending end of the other semi-U-shaped steel plate pile. A reinforced rib plate is arranged between the steel pipe and the steel plate pile. One end of the reinforced rib plate is welded and fixed on the steel pipe. The other end of the reinforced rib plate is welded and fixed on the steel plate pile. The latch type steel pipe pile has the advantages that: the large lifting equipment is unnecessary; and the latch type steel pipe pile has the advantages of shortened construction period, good safety, low cost, convenience for construction and high material recovery rate.
Description
Technical field:
The utility model relates to a kind of steel pipe pile of when deep water river is built the bridge pier cofferdam, using.
Background technology:
China railways and highway construction development are rapid, and bridge construction then becomes the key project in the communications and transportation construction.Double-walled steel cofferdams that adopt when deep water river is built the bridge pier cofferdam at present more, it is the integral body that steel plate and channel-section steel are welded into, integral lifting, sinking at the Bridge Pier Construction scene; Need large-scale lifting appliance; Long construction period, the security monitoring risk is high, and its consumable quantity is big in addition; Cost is high, and material yield rate is low.
Summary of the invention:
The utility model technical problem to be solved provides a kind of bayonet type steel pipe pile, and it can carry out assembly unit at the construction field (site), does not need large-scale lifting appliance, saves the duration, and safety is good, and cost is low, and material yield rate is high.
Above-mentioned purpose is achieved in that it comprises steel pipe, is welded with two and half U-shaped steel sheet piles on the steel pipe, the curved end of the curved end of one of them half U-shaped steel sheet pile and another half U-shaped steel sheet pile towards on the contrary.
In order to increase rigidity and intensity, can between steel pipe and steel sheet pile, establish deep floor, deep floor one end is weldingly fixed on the steel pipe, and the other end is weldingly fixed on the steel sheet pile.
The assembling method and the advantage of the utility model are: several these devices are bolted together, form the cofferdam, the curved end that is about to the steel sheet pile of another steel pipe pile that the curved end of the steel sheet pile of a steel pipe pile is adjacent is pegged graft; Because it is a monomer structure, can singlely lift by crane, sink at the construction field (site), so do not need large-scale lifting appliance; Save the duration, safety is good, and cost is low; Convenient construction, material yield rate is high.
Description of drawings:
Fig. 1 is the main TV structure sketch map of the utility model; Fig. 2 is the plan structure sketch map of the utility model; Fig. 3 is the sketch map that assembles of two adjacent the utility model.
The specific embodiment:
With reference to Fig. 1,2; It comprises steel pipe 1; A U-shaped steel sheet pile is cut open from the centre; Be divided into two and half U-shaped steel sheet piles 2, this two and half U-shapeds steel sheet pile all is the U-shaped back welding to be connect be fixed on the steel pipe, the curved end of the curved end of one of them half U-shaped steel sheet pile 3 and another half U-shaped steel sheet pile towards on the contrary.
Between steel pipe 1 and steel sheet pile 2, establish deep floor 4, deep floor one end is weldingly fixed on the steel pipe, and the other end is weldingly fixed on the steel sheet pile.
Claims (2)
1. the bayonet type steel pipe pile comprises steel pipe (1), it is characterized in that: be welded with two and half U-shaped steel sheet piles (2) on the steel pipe, the curved end (3) of the curved end of one of them half U-shaped steel sheet pile (3) and another half U-shaped steel sheet pile towards on the contrary.
2. according to the described bayonet type steel pipe pile of claim 1, it is characterized in that: between steel pipe (1) and steel sheet pile (2), establish deep floor (4), deep floor one end is weldingly fixed on the steel pipe, and the other end is weldingly fixed on the steel sheet pile.
