A construction device for friction piles

Abstract

The invention relates to a construction device of a friction pile. The construction device of the friction pile comprises a support plate, wherein an annular plate is fixedly arranged above the support plate through a fixing device; a center line of the annular plate is collinear to a center line of the support plate; two annular rails are arranged on a top surface of the support plate; a same annular rail is arranged on a bottom surface of the annular plate; the annular rail on the bottom surface of the annular plate is located right above the annular rail located on the outer side of the topsurface of the support plate; two sliding blocks are movably arranged in the annular rails on the outer side of the support plate and the bottom surface of the annular plate; a same sliding block ismovably arranged in the annular rail on the inner side of the support plate; the sliding blocks can slide along the corresponding annular rails; each sliding block is provided with a power device which is a motor; bottom surfaces of the sliding blocks located on the outer side are fixedly connected with cylinder bodies of first air cylinders; and piston rods of each two vertical first air cylinders are fixedly connected with a top surface or a bottom surface of a strip plate. A reinforcing steel bar is fixed onto a main bar of a reinforcement cage through a welding device, so that a cut-off template can be quickly installed and fixed, the labor force is saved, and the work efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to a construction device for friction piles. Background technique [0002] With the construction of large-scale projects such as high-rise, super-high-rise and long-span bridges, large-diameter super-long foundation piles are widely used as the foundation of such projects because of their advantages such as high bearing capacity and small deformation. At present, foundation piles in construction engineering generally mainly bear the load imposed by the superstructure, that is, the vertical downward load applied on the top of the foundation pile. Due to the large difference in relative displacement between the upper soil layer and the lower soil layer of large-diameter super-long piles, When the side friction resistance of the upper part of the foundation pile reaches the peak value, the side friction resistance of the lower part of the foundation pile may not be ful...

Problems solved by technology

However, at present, the fixed installation of the partition formwork is carried out entirely by manpower, the work efficiency is extremely low, and this work will consume a lot of physical strength of the staff, and often requires multiple groups of staff to complete the operation in turn, making the project cost higher
