example

[0075] The construction method of the present invention is used in the construction of retaining walls involving high slope landslides in the Xunye Road reconstruction section of the Zhaojin Red Tourist Town Project in Tongchuan City, Shaanxi Province, Anju 1st Road in Xi’an City, and Xi’an City Management Office Complex. among them:

[0076] The slope on the north side of Xunye Road is an old landslide. The front edge of the landslide is about 230.0m wide, about 180.0m long along the main sliding direction, and 170° in the main sliding direction. The maximum thickness of the sliding body is about 13.0m, and the volume is about 8.7×104m3. A medium-sized soil landslide. The upper part of the sliding surface is steep, the middle and lower part is gentle, the slope is about 60°, and the overall shape is semi-circular arc.

[0077] The new landslide is located in the center of the front edge of the old landslide. The landslide slides due to road construction and excavation. The length...

Abstract

The invention discloses a high-side-slope large-curve retaining wall building construction method. According to the method, through controlling the slope ratio of a high-side-slope retaining wall, large-curve measurement and settlement observation, reasonably arranging drainage holes and increasing the thickness and area of a sand-gravel reversed filtering layer, the construction difficulty and the measurement control precision requirement are reduced, the construction work procedure is simplified, the construction quality is ensured, the construction period is also shortened, the breakthrough achievement is obtained in the aspect of synthetically governing the landslide mass, and precious experience is provided for construction of similar ultra-high-side-slope and oversized curve retaining wall building engineering.

Description

Technical field [0001] The invention relates to a construction method of retaining wall masonry, in particular to a construction method of high slope and large curve retaining wall, belonging to the technical field of building construction. Background technique [0002] With the acceleration of the urbanization process, due to the topography and geomorphic conditions of the mountainous counties, the roads and buildings on the hillside site divide the natural hillside. Due to the limited space and the artificial influence of the later construction of the hillside site, there is an overall landslide on the slope. In order to solve the natural disasters caused by landslides, effective prevention and control are needed. Retaining wall masonry is a structure to prevent landslides. [0003] Because of topographical constraints, the masonry of retaining walls with high slopes and large curves has been increasingly used. However, the construction of high-slope and large-curved retaining w...
