Embodiment 1

[0041] Such as figure 1 As shown, a foundation pit cushion layer of this embodiment includes a template 300. The template 300 includes an upper template layer 310, a middle template layer 320, and a lower template layer 330 that are sequentially connected by pouring. The middle template layer 320 is integrally formed and The upper surface and the lower surface of the middle template layer 320 are respectively provided with extension sections extending outward and spaced apart, so that the upper surface of the middle template layer 320 and the upper template layer 310, the lower surface of the middle template layer 320 and the lower template The layers 330 each have a gap cavity 340 surrounded by extension sections.

[0042] In this embodiment, the upper surface and the lower surface of the template 300 are provided with waterproof layers, and the gap cavity 340 in the template 300 includes a large gap cavity assembly and a small gap cavity assembly. The large gap cavity assembly c...

Embodiment 2

[0045] The manufacturing system of a foundation pit cushion layer of this embodiment is used to manufacture the template 300 in embodiment 1. The manufacturing system is as figure 2 , image 3 , Figure 4 As shown, it includes a fixing mechanism 400 for fixing the template 300 and a leveling mechanism 500 for leveling the template 300. The fixing mechanism 400 includes a main body 410, a guide post 440, a drive shaft 450 and a pressing plate 430, and the guide post 440 is arranged at In the main body 410, the top end of the guide post 440 extends out of the main body 410 and is provided with a pressing plate 430, the template 300 is sleeved on the guide post 440 through a mounting hole, and is located below the pressing plate 430, and the drive shaft 450 is used to drive the guide post 440 to move up and down; As a result, the pressing plate 430 is driven to press the template 300 downwards or detach from the template 300 upwards, so as to achieve compression and reinforcement o...

Embodiment 3

[0051] The manufacturing system of a foundation pit cushion in this embodiment is basically the same as the above embodiment, and further, such as image 3 with Figure 4 As shown, the main body 410 in this embodiment is provided with a longitudinal hole 411 for placing the guide post 440 and a transverse hole 412 for placing the drive shaft 450. The longitudinal hole 411 and the transverse hole 412 intersect perpendicularly; the lower part of the guide post 440 is provided with The through hole 441 in the column through which the drive shaft 450 passes. The diameter of the through hole 441 in the column is larger than the diameter of the drive shaft 450. The lower surface of the inner wall of the through hole 441 in the column is a lower wedge surface 442, and the lower surface of the drive shaft 450 is cut A mating inclined surface 451 adapted to the lower wedge surface 442 is formed; a telescopic elastic member 460 (such as a telescopic spring) is arranged in the cavity formed...

Abstract

The invention discloses a foundation pit cushion layer and a manufacture system thereof, and belongs to the field of construction engineering. The foundation pit cushion layer comprises a template, the template comprises an upper template layer, a middle template layer and a lower template layer mutually connected in sequence by pouring, the middle template layer is formed in one body, the upper surface and the lower surface of the middle template are correspondingly provided with extension sections extending outward and spacing distribution, and gaps between the upper surface of the middle template layer and the upper template layer, and the lower surface of the middle template layer and the lower template layer are provided with gap cavities surrounded by the extension sections. According to the foundation pit cushion layer and the manufacture system thereof, the shortcoming of certainly defective using performance of the cushion layer in the prior art is overcome, through a three-layer composite structure of the template, tensile strength and bending resistance of the template can be effectively improved, change amounts of the template affected by the temperature can be reduced,and the contraction rate of thermal expansion and cold contraction of the template is reduced; and through a fixing mechanism, the template is reinforced when pouring, installation and disassembly are convenient, and operation is easy.

Description

Technical field [0001] The invention relates to the technical field of construction engineering, more specifically, to a foundation pit cushion and a manufacturing system thereof. Background technique [0002] The foundation pit cushion is the working surface constructed in the foundation pit. The function of the cushion is as follows: 1. Protect the foundation soil from the disturbance of rain, construction personnel and construction machinery; 2. Provide work for waterproofing measures for the foundation floor 3. Provide a working surface for the construction of the positioning axis; 4. Provide a working surface for tying the foundation steel bars. Therefore, the waterproof and anti-seepage and surface smoothness of the foundation pit cushion are very important and determine the construction of the foundation slab. At present, there are various structural designs for foundation pit cushions, but the pursuit of improving cushion performance in actual use has always been a hot sp...
