Inclined type pier body pouring system

Abstract

The invention provides an inclined type pier body pouring system. The inclined type pier body pouring system comprises a concrete formwork, a supporting device and a tensile force device. The concrete formwork comprises a plurality of formwork units which are enclosed to form a pouring cavity, wherein at least one formwork unit which is taken as a pressure side face is subjected to maximum inclined pressure, and a side face opposite to the pressure side face is defined as a tensile force side face; the supporting device abuts against the outside of the pressure side face; and the tensile force device is arranged in the concrete formwork and comprises horizontal pulling rods and diagonal pulling rods, wherein the horizontal pulling rods are horizontally connected to the pressure side face and the tensile force side face, and the diagonal pulling rods are connected with bottom parts of the pressure side face and the tensile force side face. According to the inclined type pier body pouring system, through implementing for the scheme, safety of construction in inclined type pier body or tower column construction can be improved, and construction cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an inclined pier pouring system. Background technique [0002] With the rapid development of transportation in our country, the types of bridges are also changing with each passing day. In the construction of bridges, generally according to the terrain of the bridge structure, for the auxiliary pier or transition pier body of the main bridge, inclined portal piers will be selected. In the inclined portal type pier, the top of the pier is provided with a transverse tie beam, and the pier body is a solid structural pier inclined outward. When constructing the inclined portal type pier, it needs to be considered that the inclined pier body or tower formwork needs to bear the concrete side pressure during the concrete pouring process due to the inclination of the pier body. In the prior art, the methods for bearing the lateral pressure caused by concrete pouring include hy...

Problems solved by technology

[0003] Among the above-mentioned methods of resisting concrete lateral pressure, although the construction of hydraulic climbing formwork has high safety and mature operation technology, the investment and cost of this treatment process are large; although the construction of cantilever formwork can better resist concrete lateral pressure , but this treatment process requires the use of tower cranes to lift during the pouring process, which has poor safety and high cost investment; the construction method using self-made triangular trusses is consistent with the cantilever formwork and requires external force, that is, tower cranes during the pouring process The safety is not good; the construction method of the stiff skeleton can resist the lateral pressure of the concrete lifted by the inclined structure by welding the tie rods to the stiff skeleton. The process is complicated and the cost is high
