Description

Precast pile splicing device permeates water

Technical Field

The utility model belongs to the technical field of precast piles, and particularly relates to a water-permeable precast pile splicing device.

Background

A precast pile is a pile (such as a wood pile, a concrete square pile, a prestressed concrete pipe pile, a steel pile and the like) made of various materials and in various forms on a co-production construction site, when in use, pile sinking equipment is used for driving the pile into the soil, pressing or vibrating the pile into the soil, wherein the concrete precast pile can bear larger load, is firm and durable and has high construction speed, and becomes one of pile types widely applied in the prior construction, but due to the influence of factors such as transportation and the like, the concrete precast pile can only be processed in sections, for the construction site using a longer precast column, the pile splicing construction of the sectioned precast pile is required in the field construction process, the prior precast pile is widely used in the field of construction, two concrete square piles which are adjacent up and down need to be connected together in the construction process, the prior art adopts the welding direction for connecting the two adjacent precast piles, in the welding process, low-carbon steel plates are embedded in the side faces and the end faces of four corners of the end parts of the upper pile and the lower pile, and the surfaces of the low-carbon steel plates are kept clean. When the lower pile is driven to the operation height convenient for welding (about 1m from the ground and the pile tip is enabled to avoid a hard soil interlayer), the upper pile is lifted by the pile frame and is aligned to the lower pile head. The verticality is corrected in two directions which mutually form 90 degrees by using an instrument, the uneven position of a joint gap is filled with an iron sheet and is firmly welded with an embedded iron plate on the end face of the pile. The inspection is errorless the back, with spot welding with four corners angle connector and pre-buried steel sheet temporary welding, inspect position and straightness back that hangs down once more, weld by two welders diagonal angle symmetry immediately, it is crooked to prevent that the node from arousing the end body because temperature stress produces welding deformation in the welding, need guarantee the coaxial coupling of both sides prefab all the time at the pile extension in-process, the precision that this kind of pile extension mode required is high, the construction degree of difficulty is big, work efficiency is low, and weld seam intensity is lower, anti transverse load is not enough, the prefab that leads to both ends takes place easily and breaks under the transverse load effect of job site, connection work at every turn needs two staff's cooperation at least in addition just can accomplish, consuming time and consuming effort, the practicality is not strong.
