Single-side side wall slip form and construction method

Abstract

Disclosed are a single-side slide wall slip form and a construction method thereof. The slip form is composed of form plates, lifting frames, back ridges, platforms, back connectors, a guide rail, guide wheel mechanisms, hydraulic jacks, limiting levelers, climb poles and a tube frame by bolt connection. Webs welded on a face plate of each form plate are provided with bolt holes and are suspended on the back ridges which are in channel shapes and made of steel, and thirty four form plates are connected to form a 30m high form plate set which inclines by 0.3%-0.5%. Each lifting frame is made of steel channels and steel angles by connecting. The back connectors are steel plates. The form plates, the platforms and the back connectors are integrally connected with the lifting frames, and are connected with the hydraulic jacks to drive the slip form to ascend. The lifting frames are fixedly connected with the lower back ridges through diagonal braces. The guide rail is made of steel channels and connected with rock anchor bolts by welding. Each guide wheel mechanism comprises guide wheels, a support and shafts and is mounted between the back ridges, and the support is connected with the guide rail through the shafts. The climb poles are made of steel tubes and fixed, and the jacks climb along the climb poles. The limiting levelers are used for adjusting climbing position. The tube frame is used for guaranteeing stable climbing. The construction method includes: casting when the slip form climbs, and concreting once.

Description

1. Technical field [0001] The invention belongs to the technical field of hydropower engineering, and particularly relates to construction equipment and a method for underground concrete pouring of large-scale hydropower projects. 2. Background technology [0002] In the past, the traditional small formwork method was used for concrete pouring of the single-sided side wall of the underground gate pier and gate chamber of large hydropower projects in China. Considering the Xiluodu project, the size of the single-sided high side wall is about 84m in length and 57m in height. The size of the traditional small formwork is generally: length: 1.5m, width: 0.3m, generally rectangular, and due to inevitable errors during manufacture and installation, the quality of the pouring is not high. As far as the pouring process is concerned, due to the limitation of the size of the traditional small formwork, during the pouring process, if the pouring is completed by one-time pouring, a lar...
