Abstract

The invention relates to a support removing device for bridge construction. The support removing device comprises an outer cylinder, an inner cylinder, packing, a water inlet pipe, a water outlet pipe, PVC hoses, a high pressure water pump and a waste water recovery tank. A support removing method matched with the support removing device includes the following steps that step 1, before the cast construction of a bridge, the outer cylinder is placed on a support body, a bracket is placed on a top plate of the inner cylinder, and then PVC hoses are connected to the water inlet pipe and the wateroutlet pipe respectively; step 2, after the construction and curing of the cast-in-place bridge are completed, the PVC hoses are connected to the high pressure water pump and the waste water recoverytank; step 3, the high pressure water pump is opened and water is pumped into the outer cylinder; step 4, as the upper packing is dissolved and discharged, the packing gradually compresses, the innercylinder gradually declines, and support removal is achieved. The device and the method solve the problems that the operation is inconvenient and it is difficult to achieve balance in the prior art,and have positive technical significance.

Description

technical field [0001] The invention relates to a falling frame device and method for bridge construction, belonging to the field of building construction equipment. Background technique [0002] With the vigorous development of our country's economy, bridge construction has entered a stage of comprehensive development, and the construction methods of bridge engineering must also keep up with the pace. [0003] At present, in bridge construction, the drop frame device of the cast-in-place box girder formwork bracket mostly adopts the sand box device, that is, the steel cylindrical sand cylinder is filled with sand, and the sand cylinder is relied on to provide bearing capacity for the surrounding sand. After the construction is completed, the sand box is opened. When the valve on the cylinder is closed, the sand flows out of the pores, and the bearing capacity disappears, that is, the falling frame is completed. The device and method mainly have the following disadvantages:...
