Three-dimensional continuous frame type reinforced concrete structure retaining wall

Abstract

The invention belongs to the field of construction engineering, and relates to a three-dimensional continuous frame type reinforced concrete structure retaining wall. The three-dimensional continuous frame type reinforced concrete structure retaining wall comprises piles which are fixedly connected through a ground beam. Columns are fixedly connected to a base plate, the columns are in rigid connection through girders so that a frame can be formed, and a shingle is arranged on the outer vertical face of the frame. The three-dimensional continuous frame type reinforced concrete structure retaining wall is simple in structure, the frame type structure is adopted, a frame body is rooted into a stable foundation supporting layer, the lateral pressure of a side slope soil layer is dispersed through the girders and the columns, the overlarge local pressure of a wall body can be avoided, anti-sliding capacity, shear capacity and bearing capacity are enhanced, the stability and the durability of the retaining wall are guaranteed, the potential risks of engineering can be greatly reduced, and the three-dimensional continuous frame type reinforced concrete structure retaining wall is suitable for enclosing and retaining side slope soil mass in loose sandy soil, recent fill and soil piling and filling areas which can not be closely grained easily.

Description

technical field [0001] The invention belongs to the field of construction engineering, and relates to a retaining wall, in particular to a three-dimensional continuous frame reinforced concrete structure retaining wall which is suitable for slope soil on both sides or one side of buildings, roads and railways, and acts as a support wall. Background technique [0002] In construction projects, retaining walls used to support and retain slope soils are widely used in areas with different elevations or to deal with local height differences, such as roads, railways and other side or side slope soils. Retaining walls include gravity type, semi-gravity type, anchor type, cantilever type and support arm type, anchor plate, reinforced soil, sheet pile type, etc. However, subject to traditional thinking patterns and economic factors, retaining walls The gravity type has always been the most commonly used, and the masonry masonry is more common. [0003] The gravity retaining wall h...

Problems solved by technology

[0005] Aiming at the defects in the existing retaining wall form, construction engineering technicians proposed a frame-type retaining wall scheme, such as patent 201110235978, which discloses an open-type reinforced concrete frame retaining wall, which is composed of a retaining wall, and a retaining wall It is composed of triangular cable-stayed walls (attached walls) connected as a whole, forming a continuous T-shaped structure. Although it can be anchored by attached pilasters to enhance stability, it can increase the stability of the retaining wall, save materials, and reduce cost, but the existing buttress-type retaining wall and prefabricated retaining wall form are still retained, and the lack of a bottom plate, the increase in pressure generated by the attached wall to the ground will easily cause the structure to become unstable, and cannot effectively resist the filling. The lateral pressure does not fundamentally change the compressive capacity of the retaining wall, so it is not suitable for slightly higher retaining wall projects, and can only be used to maintain the stability of relatively low slopes.

[0006] There are also researchers who have designed a new type of retaining wall, which is composed of a vertical plate and a frame. The soil in the frame is filled with equal and opposite earth pressure on both sides to maintain the stability of the retaining wall (Ma Chengjun et al., 1997), which is actually a square frame retaining wall with a small scope of application. It is mainly used for retaining soil on both sides of the channel in the irrigation area at the same time, which cannot meet the needs of maintaining the stability of the slope soil in the process of road construction and other building construction.
