Problems solved by technology

[0002] In the field of concrete pouring technology for water conservancy and hydropower engineering buildings, the traditional method is to pour concrete with bulk formwork, pour one piece with bulk formwork, and maintain one piece. After the concrete reaches the design strength, the bulk formwork is removed piece by piece, and then divided. Block pouring, repeat the above method until the concrete pouring is completed, the pouring construction by this method is complicated, labor-intensive and time-consuming, and the quality of concrete pouring is not easy to guarantee, such as concrete hanging curtains, wrong platform, deformation, honeycomb, etc., and the temperature deformation of concrete is not easy to control And other issues

Embodiment

[0025] Example: Pier hydraulic leveling internal climbing sliding formwork and its method of pouring concrete

[0026] (1) The production of sliding formwork, the production steps are as follows:

[0027] 1. Assembling the main truss beams around the gate pier, the upper and lower beams of the main truss beams are made of [10 channel steel, the longitudinal vertical beams between the upper and lower beams, and the connecting beams are welded between the vertical beams, and the vertical beams are made of channel steel. The beam is angle steel, the upper and lower beams of the main truss beam are welded to the vertical bar of the lifting frame, and the enclosure is welded to the vertical bar of the lifting frame, and the four enclosures around the pier are welded into a square overall enclosure;

[0028] 2. Weld the pendant on the back of the steel formwork, and weld the four formworks into a square whole and hang them on the square enclosure, and then bind the steel bars of the...

Abstract

The invention relates to a pier hydraulic leveling inner-climbing climbing form and a concrete pouring method thereby. The form consists of a slip form truss, a form system, an operating platform, a hydraulic lifting system and an accuracy control system, wherein two slip form truss girders are crosswise arranged, both ends of the two slip form truss girders are respectively connected with lifting frames, a wreath is in a quadrate or an elliptical shape and is fixed to the lifting frames, a quadrate or an elliptical form is hung and fastened on the wreath, the operating platform is divided into an upper layer and a lower layer which are both fixedly connected with the lifting frames, a hydraulic console is placed on the operating platform and a jack is installed on a crossbeam. The jack is controlled by the hydraulic console to lead the crossbeam to rise, the lifting frames are driven to upwards climb simultaneously with the wreath and the form which are connected with the lifting frames, and the concrete is poured in layers and lifted in several times; when the concrete is poured to the pier top, the climbing speed is lowered, and the form is finished and repaired after concrete pouring and is cured through water drenching after final set.

Description

1. Technical field [0001] The invention relates to the technical field of concrete pouring for water conservancy and hydropower engineering buildings, in particular to a hydraulically leveled internal climbing sliding formwork for gate piers and a method for pouring concrete. 2.
