Hydraulic construction method for slip form of concrete gate pier

Abstract

A concrete gate pier slip form hydraulic construction method comprises the following steps that S1, a part of gate piers are poured firstly, and an assembly platform is installed on the gate piers; s2, mounting a ring beam 1; s3, mounting a beam support 3, an elevated beam 2 and a lifting frame 6; s4, a protection device 9 is installed; s5, a rain and sun shading shed 10 is installed; s6, installing an up-and-down ladder stand and a horizontal and vertical measuring instrument; s7, hydraulic control equipment 5 and a center hole type hydraulic jack 7 are installed; s8, the climbing rods 12 are installed, the perpendicularity of the climbing rods 12 is checked, sliding and lifting are started, and each pair of center hole type hydraulic jacks 7 are staggered corresponding to the joints of the corresponding climbing rods 12; s9, after sliding to a designated position, an auxiliary platform 8 is installed, and a maintenance water pipe 11 is additionally installed; s10, correcting the deviation; after the sliding formwork is adopted, a support is not needed any more, an upper ladder stand and a lower ladder stand only need to be additionally arranged at the gate groove position to meet passing of constructors, and occupation and consumption of turnover materials are reduced.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering construction equipment or devices, and in particular relates to a hydraulic construction method of a concrete gate pier slip-form. Background technique [0002] In water conservancy projects, the discharge structure is a very common water conservancy facility, and the gate pier is an important water conservancy structure. The concrete pouring of the gate pier in the water conservancy project is generally constructed by a combination of standard formwork and special-shaped formwork, but for river bed type large piers. Generally, the overflow dam section occupies a wide range of the dam body structure and has a large number of gate piers. Most of the riverbed dams use staged diversion, which has strict requirements on the construction period of diversion and interception. This method has a slow construction speed and affects the construction progress. [0003] Due to the use of...

Problems solved by technology

[0004] The support structure generally adopts the method of erecting supports. Supports need to be erected around the pier for placing construction materials, pouring concrete, turnover formwork, maintenance, construction personnel going up and down the pier, etc. The supports rise with the height of the pier, occupying A large amount of materials, if multiple gate piers are constructed at the same time, the occupation of turnover materials will be even greater, which will have a great impact on construction costs
