Description

Retaining wall template

Technical Field

The utility model belongs to the technical field of retaining wall equipment, a retaining wall template is related to.

Background

The concept and the design theory of the modern reinforced soil are proposed by a French engineer Henri Vidal in the 60 th century in 20 th, and the first reinforced soil highway retaining wall in the world is successfully constructed and completed in the France Pone Nie Er Si, the invention is introduced in Japan in 1967, and the research is carried out in the 70 th year, and the special research is carried out on the anti-seismic performance of the invention; the technology is used when No. 39 California roads are built in 1972 in the United states, special organizations are established to conduct research and application work, and reinforced retaining wall technology is successively used and popularized in other countries; the reinforced retaining wall is developed and applied at the end of the 70 th century in China, the first reinforced retaining wall in China is an experimental building which is located in a field dam mining area and has 3 seats and 2-4 m of height, the engineering success causes interest in the domestic civil construction industry, and the reinforced retaining wall is rapidly developed and popularized in the industries of highways, railways, water transportation, coal, forestry, urban construction and the like in China due to the advantages of light dead weight, attractive appearance, good anti-seismic performance, economy, strong adaptability and the like. The reinforced retaining wall is a light retaining structure, is a structure formed from wall face plate, tie bar and filler, and utilizes the friction force between filler and tie bar to balance the horizontal soil pressure of filler acted on the wall surface so as to make the reinforced retaining wall form a whole body, and can resist the soil pressure of its rear filler.

The template is an important component for controlling the quality of the reinforced retaining wall and is also related to personnel safety and equipment loss. The traditional cast-in-place reinforced retaining wall template usually adopts a customized integrated steel template according to the one-step casting height of a retaining wall. Because the reinforced retaining wall is provided with the unidirectional geogrids in the vertical direction at certain intervals, a geogrid notch needs to be reserved in the middle of the integrated steel template.

The conventional custom-made integrated steel form has the following problems: firstly, when the steel template is installed, the unidirectional geogrids need to penetrate into the notches of the geogrids one by one, and the operation is inconvenient; secondly, after the geogrid passes through the steel formwork from the notch, a certain gap exists between the geogrid and the steel formwork, when reinforced retaining wall concrete is poured, concrete slurry is easy to leak out from the gap, so that a pitted surface or even a honeycomb is formed at the retaining wall, and the appearance quality of the retaining wall is poor; thirdly, when the template is removed, the steel template needs to be removed in a mode of horizontally lifting backwards so that the steel template is separated from the geogrid through the notch, and in the process, the geogrid is easy to damage and break, and even the geogrid is pulled out of the retaining wall concrete; and the dismantling speed is slow and time-consuming.
