Face slab dam rolling and slope fixing device and face slab dam rolling and slope fixing construction method

Abstract

The invention discloses a face slab dam rolling and slope fixing device and a face slab dam rolling and slope fixing construction method, and relates to the field of building construction. The face slab dam rolling and slope fixing device comprises special formworks and a formwork transfer trolley, wherein each special formwork comprises an oblong bottom plate; and the bottom plate is provided with a positioning and connecting plate, a separation plate, a movable track and a rack track. The face slab dam rolling and slope fixing construction method comprises the following steps of: mounting a first layer of special formwork; primarily rolling a bedding material; mounting a second layer of special formwork by using the formwork transfer trolley after mortar strength is allowed; lifting the second layer of special formwork by using the formwork transfer trolley to perform mortar pouring; lifting the first layer of special formwork by using the formwork transfer trolley and then translating to a third layer for mounting; performing rolling construction; and circularly repeating to finish dam face slab rolling and slope fixing. According to the face slab dam rolling and slope fixing device and the face slab dam rolling and slope fixing construction method, a concrete face slab rock fill dam bedding layer and slope fixing mortar are formed at one time, the construction quality of an upstream slope face of the face slab dam bedding material is improved, the construction progress of a dam is quickened, safe construction is facilitated, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a face dam rolling slope consolidation device and a face dam slope consolidation construction method. Background technique [0002] At present, concrete face rockfill dams are widely used in construction projects. RCC face rockfill dams built with modern technology have a history of about 40 years in foreign countries and more than 20 years in my country. For concrete face rockfill dams, the construction of the upstream slope of the cushion material is the key to the quality of the face plate, the construction progress of the dam and the construction cost. For decades, the slope rolling method has been used in the upstream slope construction of the cushion material of concrete face rockfill dams at home and abroad. According to this traditional construction method and process, the cushion material must be overfilled upstream by about 30cm. Before the panel construction, slo...

AI Technical Summary

Problems solved by technology

It takes 2-3 hours to fill the cushion material after the extrusion wall is formed, and the construction progress is limited

Extrusion wall bottom and top thicknesses are very different, providing a very uneven foundation for the panel, which may have an adverse effect on panel forces

Therefore, this technology has not been adopted in high dams
