Problems solved by technology

[0003] However, there are deficiencies in the above-mentioned structure. When the caisson is constructed in the above-mentioned structure, the caisson deflection is likely to occur, the well body is not vertical, and the upper level has a height difference, and it is difficult to sink. Insufficient excavation depth, excessive frontal resistance, too long sinking time, and increased recovery of lateral pressure

Abstract

The invention provides an open caisson construction formwork and a construction method thereof. The open caisson construction formwork comprises an annular open caisson block arranged in a soil layer, wherein a cylindrical supporting pile foundation is arranged in the annular open caisson block, a plurality of vertical connecting columns are arranged on the outer side of the annular open caisson block, the vertical connecting columns are distributed in an annular array mode, the vertical connecting columns are fixedly sleeved with the same annular outer ring, the annular outer ring is matched with the annular open caisson block, a supporting mechanism, a telescopic mechanism and a positioning mechanism are arranged in the annular open caisson block, the supporting mechanism comprises a square latticed column, and the square latticed column comprises four pieces of vertical angle steel, a plurality of pieces of transverse section steel and a plurality of pieces of inclined section steel. The open caisson construction formwork and the construction method thereof have the beneficial effects that it is convenient to use, supporting can be simply and effectively conducted in the open caisson construction period, manpower intervention is reduced, the working efficiency is improved, and it is simple and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of caisson construction, and in particular relates to a caisson construction template and a construction method thereof. Background technique [0002] The caisson is a shaft-shaped structure. It excavates the soil in the well, relies on its own gravity to overcome the friction of the well wall and sinks to the design elevation, and then seals the bottom with concrete and fills the well hole to make it a bridge pier or other structures. The foundation is generally used in the construction of foundation pits of large bridge piers, sewage pumping stations, large-scale equipment foundations, civil air defense shelters, shield assembly wells, underground lanes and station hydraulic foundation construction enclosures. In related technologies, a A caisson formwork and a construction method thereof, comprising several standard section formworks, each standard section formwork comprising a formwork unit and a support...
