Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a soft soil foundation deepening pit brick formwork. Background Art

[0002] Brick formwork is made of standard bricks into a formwork. After it has a certain strength, concrete pouring work is carried out. Brick formwork is generally used for the side walls of basement floor slabs. Due to outdoor waterproofing, waterproofing must be done on the cushion layer, and the waterproofing must extend to the brick formwork so that after the concrete is poured, the waterproofing can be turned up to the side wall concrete wall. If the side wall of the floor slab is made of formwork, waterproofing cannot be done, so the method of using bricks as formwork is adopted. In addition, in some places where the formwork cannot be removed after pouring concrete or it is very difficult to remove it, bricks are used instead of general formwork.

[0003] At present, the construction process of brick formwork requires excavation of foundation pedestal, removal of pile heads, cleaning of foundation pit, concrete cushion, laying of brick formwork lines, brick placement, masonry, hanging of lines, inspection, and finally reinforcement and plastering of brick formwork.

[0004] In soft soil foundation projects, due to the obvious thixotropy of silty soil, the soil is disturbed during construction, the structure is destroyed, and the foundation pit is difficult to dig to the designed depth, resulting in the inability to proceed with construction normally. Therefore, it is necessary to set up a pit wall reinforcement structure in the foundation pit to prevent the collapse of the soil around the foundation pit. However, in the existing reinforcement process, workers generally make temporary reinforcement structures on the construction site using stones or wooden boards to form reinforcement structures. However, this method requires making them during brick formwork construction each time, which is not only time-consuming and labor-intensive, but also the reinforcement is not stable enough and is prone to collapse risks.
