Problems solved by technology

However, the processing method of the brick tire mold itself also has some disadvantages
[0003] Brick tire formwork first needs to build bricks in the foundation pit. Since construction workers need to go down the foundation pit to build bricks, a large construction space is required, which requires a larger area to be excavated when excavating the foundation pit. After the construction of these brick tire molds is completed, a large gap will inevitably be formed between the brick tire molds and the outer wall of the foundation pit, thus requiring a large amount of backfill soil, which greatly wastes manpower and material resources, increases the construction procedure, and delays the construction time.
From this point of view, the brick tire mold itself is a processing method with many processes, a large workload, and cannot be formed at one time.
In addition, the brick tire mold requires a large amount of clay bricks, which will cause great harm to the environment

Embodiment 1

[0016] Pouring tire mold of the present invention comprises the following steps:

[0017] The first step is to discharge the accumulated water in the foundation pit;

[0018] The second step is to excavate the earthwork to the design depth of the foundation pit;

[0019] The third step is as image 3 As shown, the first template 3 is supported along the inner wall of the membrane foundation pit 102;

[0020] The fourth step is as Figure 4 As shown, concrete is poured between the outer wall 101 of the foundation pit and the first formwork 3 and compacted by vibrating to complete the pouring of the tire mold 2;

[0021] The fifth step is as Figure 5 As shown, after the strength of the concrete reaches the standard, the template 3 is removed to complete the pouring of the entire tire mold.

[0022] From the perspective of this embodiment, when pouring the tire mold structure described in this embodiment, only a circle of formwork 3 is supported on the inner side of the tir...

Embodiment 2

[0024] In the process of pouring the tire mold 2, since the outside of the tire mold 2 directly uses the excavated outer wall 101 of the foundation pit as a template, the condition of the outer wall 101 of the foundation pit affects the pouring of concrete.

[0025] If the outer wall 101 of the foundation pit seeps into the foundation pit, it will definitely affect the strength of the tire mold.

[0026] If the stability of the outer wall 101 of the foundation pit is poor, the soil layer on the outer wall 101 of the foundation pit falls off into the foundation pit, which will affect the smooth progress of concrete pouring. In the process of pouring concrete, once the soil layer of the outer wall 101 of the foundation pit collapses or falls into the concrete, not only will the strength of the concrete be reduced, but also the regularity of the shape of the tire mold 2 will be broken, resulting in uneven stress.

[0027] In this embodiment, some processes will be added to deal w...

Embodiment 3

[0037] Such as Figure 7 , Figure 8 with Figure 9 As shown, the difference with embodiment 2 is that when the fifth step of embodiment 2 is carried out, the steel formwork 5 is not raised after the concrete injection is completed, but the steel formwork 5 is lifted while injecting concrete, and at the same time Vibrate. This embodiment is suitable for deep foundation pits. The deeper the foundation pit, the more concrete needs to be injected. If the steel formwork is lifted after the concrete is poured, it will inevitably be squeezed by the outer wall 101 of the foundation pit and the concrete on the steel formwork 5. Due to the strong friction formed by the pressure, a large mechanical force is needed to lift the steel formwork out of the foundation pit. If just mention steel formwork 5 after concrete pouring is finished, just need to overcome powerful pressure and frictional force, as the power of machinery is less, just can't finish this work. On the contrary, the con...

Abstract

The invention discloses a moulding bed structure and a pouring method and relates to treatment before foundation concrete is poured in the building construction. The moulding bed structure and the pouring method aim at solving the problems that in existing brick moulding bed construction, a large number of clay bricks are needed, one-time forming can not be achieved, and a large amount of backfill is needed after construction is completed. The structure and the pouring method save time and labor and facilitate environmental protection. The moulding bed structure is composed of a moulding bed, an outer foundation pit wall and an inner moulding bed foundation pit wall, wherein the moulding bed is formed by being poured on the outer foundation pit wall in the longitudinal direction; the moulding bed makes tight contact with the outer foundation pit wall. The pouring method of the moulding bed structure comprises the steps of earth excavation, foundation pit dewatering, supporting of a moulding bed inner side formwork, pouring of the moulding bed, detaching of the formwork and the like.

Description

technical field [0001] The invention relates to reinforcement of building foundation pits, in particular to foundation tire molds. Background technique [0002] At present, in the process of building construction, brick tire molds are often used. This processing method is simpler and more economical than other methods. However, the processing method of the brick tire mold itself also has some disadvantages. [0003] Brick tire formwork first needs to build bricks in the foundation pit. Since construction workers need to go down the foundation pit to build bricks, a large construction space is required, which requires a larger area to be excavated when excavating the foundation pit. After the construction of these brick tire molds is completed, a large gap will inevitably be formed between the brick tire molds and the outer wall of the foundation pit, thereby requiring a large amount of backfill, which greatly wastes manpower and material resources, increases the constructi...
