Construction device, construction system and construction method for disengaging type pile plate structure

Abstract

The invention relates to the technical field of geotechnical engineering. The invention particularly relates to a construction device, a construction system and a construction method for a disengagement type pile plate structure. The constructiodevice comprises a construction template for pouring a bearing plate, and at least two truss type bearing beams are arranged at the bottom of the construction formwork. Jacking devices are arranged at the bottoms of the two ends of the truss type bearing beam correspondingly. The jacking devices are used for jacking the corresponding truss type bearingbeams, the construction formwork comprises an L-shaped steel formwork body, a plane steel formwork body and a U-shaped baffle, the plane steel formwork body is detachably connected with the L-shaped steel formwork body, the plane steel formwork body is detachably connected with the U-shaped baffle, the U-shaped baffle is detachably connected with the L-shaped steel formwork body, and the L-shapedsteel formwork body and the plane steel formwork body are both arranged on the truss type bearing beam. According to the construction device for the disengagement type pile plate structure, after pouring of the bearing plate is finished, the bearing plate can be effectively disassembled and repeatedly used, so that construction consumables are reduced, engineering investment is reduced, and the situation that foundation upheaval acting force is transmitted to the bearing plate is avoided.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a construction device, a construction system and a construction method for a hollow pile-slab structure. Background technique [0002] The uplift deformation of rock and soil foundations is a key problem to be solved in many projects nowadays. In the field of high-speed ballastless railways, frost heaving of permafrost, expansive rock (soil) expansion, red bed soft rock arching, saline soil (rock) salt Arching of the foundation caused by swelling and other factors is a new type of problem for railway builders. Due to the extremely strict requirements on the deformation control of high-speed ballastless railways, once the deformation of the foundation uplift exceeds the limit, it is easy to cause cracks in the ballastless track slabs of high-speed railways, causing major ballastless track defects, affecting the stability and comfort of train operation, and causing...

Problems solved by technology

[0006] The purpose of the present invention is to: for the prior art, the bottom formwork and support columns used for pouring the load-bearing slab are difficult to effectively dismantle and reuse the formwork and support columns after the load-bearing slab is poured, and the construction consumables are large, which increases the project investment. The load-bearing plate needs to bear the uplift force transmitted from the support column to the formwork, which may cause uneven uplift of the load-bearing plate and affect the smoothness of the track. A construction device, construction system and construction method for a hollow-out pile-slab structure are provided , after the bearing plate is poured, it can be effectively dismantled and reused, thereby reducing construction consumables, reducing project investment, and avoiding the transmission of the foundation uplift force to the bearing plate
