Problems solved by technology

However, in many projects, the top of the retaining wall is the red line of the project, or there are some pipelines or foundations of buildings (structures) in the fill behind the wall, which limits the use of oblique anchor cables

Embodiment 1

[0036] The original height of the gravity-type retaining wall in the family apartment area of ​​a factory was 6.0m, and the height of the rear retaining wall increased to 9.0m with the increase of the fill behind the wall. After 2 to 3 years of operation, it was found that the back of the retaining wall appeared A large number of "bulging", cracks and other phenomena, the total length of the retaining wall with instability phenomenon is 50.0m. The preliminary reinforcement plan is to use lattice beams and columns + oblique prestressed anchor cables. However, since the red line of the retaining wall is located at the top of the retaining wall, local villagers do not allow this plan to be implemented. Later, vertical prestressed anchors are adopted. Cable + reinforced concrete cantilever retaining wall for reinforcement, so far, the operation is in good condition.

[0037] The cantilever retaining wall and the ground beams described in this embodiment are all made of reinforced ...

Abstract

The invention provides a method for reinforcing a gravity type retaining wall. A cantilever type retaining wall (4) is additionally arranged nearby the wall foot of the gravity type retaining wall (1), a vertical pre-stressed anchor cable (3) is additionally arranged at the bottom of the cantilever type retaining wall (4), the position between the gravity type retaining wall and the cantilever type retaining wall is filled with rubble concrete (6), and therefore the overall stability of a side slope and the retaining walls can be improved through a three-pronged mode. According to the method for reinforcing the gravity type retaining wall, the deformation resistant capability is strong, the construction working face is small, the mode that hole drilling is conducted firstly, and then the cantilever type retaining wall (4) is constructed is adopted, hole drilling on the cantilever type retaining wall (4) can be avoided, and the construction difficulty is reduced; and the construction period is short, the construction cost is low, and large application value and social benefits are achieved.

Description

technical field [0001] The invention relates to building technology, in particular to building reinforcement technology, in particular to a reinforcement method for gravity retaining walls. Background technique [0002] Gravity retaining wall has been widely used in the construction industry due to its wide source of raw materials, low cost and easy construction. Especially in mountainous areas, it has become the most widely used slope support type. However, due to the defects of this kind of retaining wall, such as weak anti-deformation ability, it is prone to instability problems, such as cracks, bulges, uplifts at the bottom of the wall, and even Landslides, etc. If these problems are not dealt with in time, they will bring great safety hazards, cause financial and material losses, and seriously threaten life safety. [0003] In order to prevent the above hidden dangers, gravity retaining walls usually need to be reinforced. The most common reinforcement methods for grav...
