Fast piling device

Abstract

The invention discloses a fast piling device. The fast piling device comprises a pile body and a pile head which are fixedly connected. The pile head comprises a concrete body and at least two steel plates, wherein the concrete body and the at least two steel plates are fixedly connected. The concrete body is of a cavity rotating body structure. The at least two steel plates are evenly distributed in the circumferential direction of the concrete body. The length directions of the steel plates are parallel to the axial direction of the concrete body. The bottoms of the steel plates are each of a gathered shape structure. According to the technical scheme, in the construction process of a steel pipe pile, the pile side friction force and pile end resistance can be reduced, a hard clamping layer can be quickly penetrated, the piling speed is effectively improved, and more using value is achieved.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a quick piling device. Background technique [0002] Steel pipe piles are the product of the rapid development of civil construction in my country, and they are mainly used for the infrastructure in the construction of wharves and ports. At present, during the pile sinking construction of steel pipe piles, the static pressure method is generally adopted. Although this method has the advantages of high driving resistance, little impact on the surrounding environment, and short construction period, it has the advantages of pressing in, but it is not suitable for piles mixed with pebbles. When the hard ground such as sand grain layer or rock plate, or the reinforced concrete structure obstacle existing underground, will cause relatively large vibration and pile driving speed due to the increase of pile end resistance, and will produce certain The amount of soil squeezed will have...

Problems solved by technology

At present, during the pile sinking construction of steel pipe piles, the static pressure method is generally adopted. Although this method has the advantages of high driving resistance, little impact on the surrounding environment, and short construction period, it has the advantages of pressing in, but it is not suitable for piles mixed with pebbles. When sandy layer or rock plate and other hard geology, or encountered underground reinforced concrete structure obstacles, due to the increase of pile end resistance, it will lead to relatively large vibration and pile driving speed, and will produce certain The amount of squeezed soil will affect the surrounding environment
