What is a retaining wall ? To be honest, Xiao Bian can only understand the meaning of the surface before he finds it, but he can't make up his mind. After the search, Xiaobian found that it was wrong. Renovation of the following Xiaobian home renovation will bring the retaining wall profiles as well as retaining wall construction plan, think up posture friends on Check it out.
What is a retaining wall ?
Retaining wall refers to a structure that supports roadbed filling or hillside soil, preventing filling or soil deformation and instability. In the cross section of the retaining wall, the part directly contacting the supported soil is called the wall back; the part opposite to the back of the wall is called the wall; the part directly contacting the ground is called the base; The top surface of the wall is called the top of the wall; the front end of the base is called the wall toe; the back end of the base is called the wall.
Retaining wall construction plan :
1. Measurement and stakeout: Use the total station to release the edge of the retaining wall, draw out the excavation range, nail the pile, and arrange the control pile near the construction site.
2 , cleaning the foundation pit and substrate treatment: according to the measurement of the foundation pit construction range and design depth for excavation. The wall foundation should be placed on a reliable rock formation, and the foundation is buried in the strong weathering layer of the bedrock 1 ~ 2m . If the foundation is not in conformity with the design, the supervision engineer is requested to change the construction plan.
3 , template installation
Template making: Steel templates should use standardized combination templates. The assembly of the composite steel formwork shall comply with the current national standard. Various bolt connections should comply with relevant standards. The steel formwork and its fittings shall be processed according to the standard processing drawings, and the finished product may be used after passing the inspection.
B template installation: the template and the steel bar installation work should be carried out in coordination, and the template for preventing the binding of the steel bar should be installed after the steel bar is installed. When installing the side template, prevent the template from shifting and deforming. The base side mold can be fixed and fixed outside the template. The tie rods placed in the concrete shall be taken according to the requirements of pulling out or not pulling out the rods. For small structures, metal wires can be used instead of tie rods. After the template is installed, the plane position, top elevation, node contact and vertical and horizontal stability should be checked. After passing the concrete, concrete can be poured. When pouring concrete, if it is found that the template has the possibility of exceeding the allowable deviation deformation value, it should be corrected in time. The template must be equipped with an anti-overturning facility during the installation process.
4. Concrete production and transportation
Concrete mixing: When mixing concrete ingredients, the various scales should be kept accurate. The water content of the aggregate should be checked frequently. During the rainy season, the number of measurements should be increased, and the amount of aggregate and water should be adjusted accordingly. The concrete mixture should be evenly mixed and the color should be the same. There should be no segregation and bleeding phenomenon when transported to the site. Concrete is transported by tankers for concrete, so that the pouring work is uninterrupted. The uniformity and the specified slump are maintained while transporting the concrete to the pour site. After stirring at the transport distance by the tanker should be transported to the remote site concrete pouring again for 1-2 minutes, then concrete construction. It is strictly forbidden to use unqualified concrete for construction.
Pouring of concrete: Before the concrete is poured, the brackets, formwork and steel bars should be inspected and recorded, which can be poured after meeting the design and construction requirements. The water in the formwork before the concrete is poured should be cleaned up. If there is a gap in the template, use a sponge strip or double-sided tape to fill tightly. The mold should be coated with a release agent ( no oil such as waste engine oil ) .
5 , concrete health and template removal
After the pouring is completed, it should be covered and sprinkled as soon as possible after initial setting. The surface of the concrete should not be damaged or contaminated when covered. When the concrete is covered with the formwork, the formwork should be kept moist during the curing period. The maintenance standard is to keep the concrete surface moist, and the curing days are not less than 7 days. Demolition of the formwork: The removal of the formwork shall be carried out in the order of the design requirements. When there is no requirement for the design, the first branch shall be dismantled and the rear branch shall be dismantled first. The unloading brackets and arches shall be carried out according to the proposed unloading procedure, and shall be unloaded in several cycles. The amount of unloading shall be small and gradually increase thereafter. In the longitudinal direction, the symmetry should be unbalanced and unloaded in the horizontal direction. When removing the formwork, unloading the bracket and the arch frame, it is not allowed to use violent tapping and strong twisting. After the template and bracket are removed, they should be repaired and sorted and stored properly.
6 , settlement joint setting
By design position setting settlement joint, when the retaining wall, according to the position of settlement joint section construction, retaining wall construction is completed, the settlement joint oakum along with pitch, outer, top tripartite packing, depth 10 ~ 20cm.
The above is what Xiaobian brought to you.  What is a retaining wall ?
