Description

Novel prefabricated PHC tubular pile Technical Field The utility model relates to the technical field of PHC pipe piles, in particular to a novel prefabricated PHC pipe pile. Background PHC pipe pile is short for prestressed high-strength concrete pipe pile, adopts pretensioned prestressing centrifugal forming process, is made through high-temperature steam curing, and can be widely applied to various building engineering and road and bridge engineering, including high-rise, multi-layer building, large-span structure, industrial factory building and the like. Through retrieving, the bulletin number is CN210315506U, and the name is a prefabricated PHC tubular pile, including hollow pile body, the one end of pile body is equipped with the pile head, discovers through research analysis that, though having the partial soil body that makes prefabricated PHC tubular pile below get into the pile body, the lateral displacement of the soil body around the prefabricated PHC tubular pile is less with surging, and the vertical compression volume of the stake side soil body of adjacent prefabricated PHC tubular pile is less, and the higher effect of quality of pile group construction still exists following defect to a certain extent. If the two sides of the pipe pile cannot be protected, because the outer surfaces of the two sides of the pipe pile are wrapped by metal materials, rust can easily occur in the storage process, and the two ends of the pipe pile cannot be subjected to rust protection, polishing and rust removal are required before welding the two pipe piles during construction, so that the labor intensity of personnel is increased, the construction efficiency is affected, meanwhile, the limiting function is not provided in the connection process of the two pipe piles, the alignment between the two pipe piles is easily affected by rotation, and in order to solve the technical problem, a novel prefabricated PHC pipe pile is designed. Disclosure of utility model The utility model aims to provide a novel prefabricated PHC pipe pile, which has the functions of rust prevention and protection, does not need polishing and rust removal, reduces labor intensity of personnel, can limit during connection, accelerates alignment speed, improves construction efficiency, and solves the problems that rust prevention and rust removal are needed before welding, labor intensity of personnel is increased, the alignment cannot be carried out in the connection process, and construction efficiency is affected. In order to achieve the above purpose, the novel prefabricated PHC pipe pile comprises a pipe pile body, wherein a limiting slot is formed in the top of the pipe pile body, a limiting bump is fixedly connected to the bottom of the pipe pile body, a protective sleeve is sleeved on the top and the bottom of the pipe pile body in a sliding mode, waterproof cloth strips are fixedly connected to the inner side of the protective sleeve, elastic binding strips are sewn on the outer surfaces of the waterproof cloth strips, and magic tapes are sewn on the surfaces of the elastic binding strips. Preferably, the protective sleeve comprises a sleeve, a cover plate is fixedly connected to the outer side of the sleeve, and protective iron sheets are embedded in the sleeve and the cover plate. Preferably, the sleeve and the cover plate are both made of polypropylene materials, and a rubber buffer pad is glued on the inner side of the cover plate. Preferably, the velcro is divided into a fur velcro and a fur velcro, the fur velcro is fixedly connected with the left side of the rear side of the elastic bandage, and the fur velcro is fixedly connected with the front surface of the elastic bandage. Preferably, the tubular pile body comprises a pile body, wherein the top and the bottom of the pile body are fixedly connected with backing plates, and the top and the bottom of the outer surface of the pile body are fixedly sleeved with protection steel rings. Compared with the prior art, the utility model has the following beneficial effects: The lag cover is at the both ends of tubular pile body, and elastic bandage twines on waterproof cloth strip's surface and is taut with the power, ties waterproof cloth strip and avoids rainwater and protection steel ring contact, can rust-resistant protection to the protection steel ring like this, does not need personnel to polish rust cleaning, alleviates personnel's intensity of labour. Through setting up spacing slot and spacing lug, can carry out spacingly when two tubular piles splice, make in the spacing slot of another tubular pile one end is inserted to spacing lug of one tubular pile one end, can prevent like this that the tubular pile of top from taking place to rotate when the welding, effectual improvement efficiency of construction.
