Problems solved by technology

Due to the large height difference of the fill slope, in order to ensure that the retaining wall has sufficient capacity to balance the thrust of the fill slope, the existing technology usually increases the thickness of the reinforced concrete retaining wall to increase the internal force of the retaining wall, but such a In the future, the project cost will be greatly increased; another method is to increase the distance between the buttress columns, but the height difference of the existing fill slopes is very large. As the depth increases, the soil pressure increases. It is difficult to effectively reduce the construction cost by the method

Embodiment Construction

[0023] Best practice:

[0024] Refer to attached figure 1 , the design and construction method of reinforced concrete retaining wall, including the following steps:

[0025] 1. Calculate the design height of the segmented soil wall slab based on the actual situation of the site and the performance of the filler and the required height of the overall reinforced concrete retaining wall, so as to reasonably plan the number, elevation, length and thickness of the balance slab;

[0026] 2. Carry out foundation construction on reinforced concrete wall panels;

[0027] 3. Pouring the first section of reinforced concrete wall panels and rib columns at a set height, and filling the back of the wall: including compacting, making filter and drain holes, and leveling the back filling of the wall;

[0028] 4. Provide the first balance board, which includes a platform board and ribs. The balance board is installed on the side of the second reinforced concrete wall panel fill, and one end ...

Abstract

The invention relates to a construction method for a retaining wall, in particular to a design and construction method for a reinforced concrete retaining wall. During construction, a sectional construction mode is adopted, balance plates are mounted on one side of a side slope of a retaining wall during construction, earthwork is filled in the side slope, construction of an Nth balance plate and an N+1th reinforced concrete wallboard is sequentially carried out until the designed integral height of the retaining wall is achieved, accordingly, the balance plates lead the retaining wall to generate torque resisting to the side slope filled with the earthwork under effects of gravity of the earthwork above the balance plates when the side slope filled with the earthwork generates thrust to the retaining wall, internal stress of the reinforced concrete retaining wallboards is balanced, safety and reliability of the retaining wall are improved, the wallboards do not need to be thickened, the construction method is simple and feasible, engineering cost is greatly lowered, and construction land is reduced.

Description

technical field [0001] The invention relates to a construction method of a retaining wall, in particular to a design and construction method of a reinforced concrete retaining wall. Background technique [0002] When the substation or power plant site area is located in a mountainous area, high fill slopes are often formed due to topographical reasons, and reinforced concrete retaining walls are often required due to land use restrictions. Due to the large height difference of the fill slope, in order to ensure that the retaining wall has sufficient capacity to balance the thrust of the fill slope, the existing technology usually increases the thickness of the reinforced concrete retaining wall to increase the internal force of the retaining wall, but such a In the future, the project cost will be greatly increased; another method is to increase the distance between the buttress columns, but the height difference of the existing fill slopes is very large. As the depth increa...
