Embodiment Construction
[0016] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0017] The implementation of the present invention will be described in detail below in conjunction with specific drawings.
[0018] Such as Figure 1~3 Shown is a preferred embodiment provided by the present invention.
[0019] The retaining wall 11 provided in this embodiment is a masonry rubble retaining wall 11, which is then filled with soil. The horizontal thrust of the rock and soil behind the retaining wall 11 produces an overturning moment on the retaining wall 11, and the retaining wall 11 is required. The moment generated by its own gravity is used to balance the outer surface of th...

The invention relates to a construction method for reinforcing a retaining wall, and discloses a construction method for reinforcing a mortar rubble retaining wall and a structure of the mortar rubble retaining wall. The construction method for reinforcing the mortar rubble retaining wall comprises the following steps that (1) a reinforced concrete face plate and vertical ribs are poured on the outer side face of the mortar rubble retaining wall, and sleeves are reserved in the reinforced concrete face plate and the vertical ribs; (2) a jumbolter is used for drilling in a wall and a wall rear rock-soil body through the sleeves; (3) anchor rods are arranged, one end of each anchor rod is arranged in an anchor rod hole, and the other end of each anchor rod extends out of the reinforced concrete vertical ribs; (4) grouting is carried out on drilled holes, and tension locking is carried out after grout solidifies and the design strength is achieved. When the construction method for reinforcing the mortar rubble retaining wall is used, a reinforced structure of the retaining wall can be formed on the outer side of the retaining wall; due to the facts that firstly, the reinforced concrete face plate and the vertical ribs are formed on the outer side face of the retaining wall, and then drilling is carried out on the wall body through the reserved hollow sleeves, dropping of large-area rubble on the retaining wall can be avoided, the integral structure of the retaining wall cannot be damaged, the retaining wall is well protected, and collapse of the retaining wall in the process of construction is avoided.
Description
technical field [0001] The invention relates to the technical field of reinforcement construction methods for retaining walls, in particular to a reinforcement construction method for masonry rubble retaining walls. Background technique [0002] The masonry rubble retaining wall is a common retaining structure, which has the advantages of convenient construction, simple structure, and low cost, and is especially suitable for construction in places with sufficient stone sources. However, due to the low tensile strength of the wall, the overturning moment caused by the earth pressure acting on the back of the wall is completely balanced by the anti-overturning moment generated by the self-weight of the wall. Therefore, the masonry quality of the wall body of the retaining wall greatly affects the stability and service life of the retaining wall. However, the retaining wall is prone to factors such as poor quality of wall masonry, loose fill behind the wall, blockage of draina...
