Abstract

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 void-type pile-slab structure, including a construction formwork for pouring a load-bearing slab, and at least two truss-type bearing plates are arranged at the bottom of the construction formwork Beam, the bottom of both ends of the truss-type load-bearing beam are respectively equipped with jacking devices, which are used to lift the corresponding truss-type load-bearing beam. The construction formwork includes L-shaped steel formwork, plane steel formwork and U-shaped baffle, and plane steel formwork The L-shaped steel formwork is detachably connected, and the flat steel formwork is detachably connected with a U-shaped baffle. A construction device for a hollow-out pile-slab structure of the present invention can be effectively dismantled and reused after the bearing slab is poured, thereby reducing construction consumables and project investment, and avoiding the transmission of foundation uplift force to the bearing slab .

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...
