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

Embodiment 1

[0071] like Figure 1-7 As shown, a construction device for a void-type pile-slab structure described in this embodiment includes a base 11, a jack 12, a truss-type load-bearing beam 3, an L-shaped steel formwork 21, a plane steel formwork 22, and a U-shaped block plate 23. The base 11 is poured with concrete and placed in the cutting foundation 5; the jack 12 and the truss-type load-carrying beam 3 are sequentially arranged on the base 11 from bottom to top; the L-shaped steel formwork 21 and the plane steel formwork 22 are vertically erected along the line On the truss load beam 3 ; the U-shaped baffle 23 is placed on the joist 42 .

[0072] The truss-type load-bearing beam 3 is made of segmental assembled rigid structure, and the length of each segmental rigid truss is not greater than the distance from the edges on both sides of the load-bearing plate 43 to the toe of the cutting slope. The function of the truss-type load-bearing beam 3 is to carry the L-shaped steel for...

Embodiment 2

[0078] like Figure 1-7 As shown, a construction device for a hollow pile-slab structure described in this embodiment differs from Embodiment 1 in that it includes a construction formwork 2 for pouring a bearing plate 43, and at least two truss-type The load-carrying beam 3 is arranged at the bottom of the construction formwork 2 for stably supporting the construction formwork 2. The construction formwork 2 is a box-shaped member with an open top, and the construction formwork 2 is set as a L-shaped steel formwork 21. The structural member spliced ​​by plane steel formwork 22 and U-shaped baffle 23, after the loading plate 43 is poured, the construction formwork 2 can be split into L-shaped steel formwork 21, plane steel formwork 22 and U-shaped baffle 23, so that the effective dismantling of the construction formwork 2 can be realized very simply, and the situation that the foundation uplift works and transmits the load-bearing plate 43 through the construction formwork 2 doe...

Embodiment 3

[0090] like Figure 8-10 As shown, a construction system described in this embodiment includes a foundation 5 and the construction device as described in Embodiment 1 or 2, the base 11 is a structural member formed by pouring concrete, and the base 11 is arranged on In the foundation 5 , all the truss-type load-bearing beams 3 are longitudinally spaced along the line, and the U-shaped baffles 23 are placed on the joists 42 .

[0091] During installation, since the bearing plate 43 extends longitudinally along the line, all the truss-type load-bearing beams 3 are distributed longitudinally along the line to facilitate better disassembly in the later stage. Good strength, avoiding the settlement of the base 11 during the jacking process of the jack 12, causing the truss-type load-bearing beam 3 to tilt and slide. The U-shaped baffle 23 is placed on the joist 42, relying on the joist that has been made 42 to support and position the U-shaped baffle 23, so as to ensure the precis...

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...
