Gravity retaining wall structure with culvert and its construction method

Abstract

The invention discloses a gravity type retaining wall structure with a culvert and a construction method thereof. A gravity type retaining wall (1) and a culvert concrete body (15) form an integral structure by virtue of an underground part (13) of the retaining wall culvert, a culvert body formed by a culvert space (9) in a prefabricated culvert pipe (14) and the culvert concrete body (15) and the gravity type retaining wall (1) are arranged in parallel, the culvert concrete body (15) is located below the foot of the outer side of a wall body of the gravity type retaining wall (1), and a retaining wall foundation (6) and a culvert foundation (7) are combined as a foundation of a combined structure. According to the gravity type retaining wall structure, the gravity type retaining wall and a ditch or a pipe culvert which needs to be formed at the bottom of a side slope are integrated, so that the systemic structure is enhanced, the requirement of plane space is lowered, the foundation excavation depth is reduced, the retaining effect of the retaining wall on the side slope is strengthened, the overturning resistant capability is increased, and additionally, the problems of required space for bottom drainage or pipeline installation of the side slope and stable support of the side slope are solved.

Description

technical field [0001] The invention belongs to the technical field of slope support engineering, and in particular relates to a gravity retaining wall structure with a culvert and a construction method thereof. Background technique [0002] Retaining wall is a commonly used slope support measure, mainly including gravity retaining wall and buttress retaining wall. Gravity retaining walls can be divided into inclined retaining walls, inclined retaining walls, vertical retaining walls and counterweight retaining walls. The materials of the retaining wall mainly include concrete and mortar masonry, etc., and the construction methods are mainly stacking and vertical casting. [0003] Generally, the outside of the bottom of the slope needs to construct drainage or pipe culverts parallel to the slope. Ditches or pipe culverts generally need to keep a certain safe distance from the retaining wall, but the space in the lower part of the slope is often limited, which brings proble...

AI Technical Summary

Problems solved by technology

The retaining wall is to solve the stability problem of the side wall of the hydropower station at the foot of the dam. Located inside the counterweight platform 2 of the retaining wall, the channel 3 in the retaining wall reduces the weight of the counterweight platform, which is detrimental to the stability and anti-overturning effect of the retaining wall. In order to remove the adverse effects of internal holes on the integrity and stress adjustment of the retaining wall, It is necessary to increase the volume of the counterweight platform where the hole is located, and the passage is a city gate type, and the inner mold needs to be poured

[0005] For general natural slopes and artificial slopes formed by excavation, there are no patents and documents on the integration of retaining walls and culverts; no patents and documents on culverts arranged in close parallel to the outer foot of gravity retaining walls, and no culvert retaining Patents and documents of wall concrete pouring using finished pipes as internal molds
