The construction plan of the reinforced concrete retaining wall with a height of 12 m is urgently re

First of all, the basic situation of the retaining wall should be understood according to the design drawings, including the height and length of the retaining wall, the thickness of the masonry, the embedded depth of the foundation, the thickness of the foundation structure and the foundation, etc., to determine the method of excavation of the retaining wall foundation (manual or mechanical), and then the retaining wall is laid out according to the drawings, and then the retaining wall foundation is excavated to the design elevation, the foundation is leveled and compacted, and finally the foundation of the retaining wall is poured, and if the foundation is higher, it is poured in layers.

Retaining wall refers to the structure that supports the subgrade fill or hillside soil and prevents the deformation and instability of the fill or soil.

In the retaining wall cross-section, the part that is in direct contact with the supported soil body is called the wall back; The part opposite the back of the wall and the part that is open is called the wall; The part that is in direct contact with the foundation is called the substrate; The top surface of the wall, opposite to the base, is called the top of the wall; The front end of the base is called the wall toe; The back end of the substrate is called the heel.

According to its stiffness and displacement mode, it can be divided into rigid retaining wall, flexible retaining wall and.

There are three types of temporary support.

According to the environmental conditions, it can be divided into general area retaining wall, flooded area retaining wall and ** regional retaining wall.

In general, retaining walls in general areas are divided into shoulder walls, embankment walls, cutting walls and hillside walls according to the location of the retaining walls. The retaining wall installed on the embankment slope is called the embankment wall; A retaining wall with the top of the wall located on the shoulder is called a shoulder wall; The retaining wall that is arranged on the slope of the cutting is called the cutting wall; The retaining wall that is installed on the hillside and supports the overburden soil or broken rock layer that may collapse on the hillside is called the hillside wall.

According to the structural characteristics, it can be divided into stone gravity type, stone masonry constant weight type, reinforced soil gravity type, concrete semi-gravity type, reinforced concrete cantilever type and arm type, anchor type and anchor plate type, vertical prestressed anchor type, etc.

According to the wall material, it can be divided into stone retaining wall, concrete retaining wall, reinforced concrete retaining wall, steel plate retaining wall, etc.

According to the force mode, it is divided into inclined retaining wall and load-bearing retaining wall.

The foundation of the retaining wall is also called the foundation, and the construction process is probably like this:

1. First of all, it is necessary to understand the basic situation of the retaining wall according to the design drawings, such as the height and length of the retaining wall, the thickness of the masonry, the embedded depth of the foundation, the thickness of the basic structure and the foundation, etc., to determine the method of retaining wall foundation excavation (manual or mechanical);

2. Carry out retaining wall pay-off according to the drawings;

3. The retaining wall foundation is excavated to the design elevation, and the foundation is leveled and compacted;

4. Pouring the foundation (foundation) of the retaining wall, if the foundation is higher, it is poured in layers;

5. When the foundation reaches the strength requirements, the next process will be carried out.

Hello dear! We'll be happy to answer for you. The retaining wall is 3 meters high and the reinforcing steel bar is long due to the blanking

Hello dear, 1) Plate short span reinforcement: length: according to the reinforcement is the bottom or the trapped is the top, according to the calculation method of bottom gluten and gluten; Number of roots:

Directly take the number of input reinforcement roots; If the plate is laid out only with bottom gluten or gluten, the opening reinforcement calculates only the reinforcement at the bottom or top, and if both the bottom and the gluten are arranged, the opening reinforcement calculates the reinforcement at the bottom and top at the same time. When the number of reinforcements is even, half is calculated according to the bottom gluten and half is calculated according to the gluten; When the number of reinforcements is odd, it is calculated according to (n-1) 2+1 according to the bottom reinforcement, and (n-1) 2 according to the gluten. 2) Plate length span reinforcement:

Length: width of the opening + 2 * number of lae roots: directly take the number of input reinforcement roots When the slab hole is close to the support at the edge of the slab, the slab length spans the reinforcement and extends into the wall according to the bottom balance calendar or the top reinforcement 3) Oblique reinforcement length:

Length: 2*Anchorage value; Number of reinforcements: The number of reinforcement directly entered is calculated according to the length of the stressed ribs.

This requirement can now be entered in other reinforcements, and can be set later when there is more demand.

Your description is very general and cannot give a detailed description of the construction environment.

3---4 m high reinforced concrete retaining wall:

Construct a large sample.
