Description

box retaining wall

Technical field:

The utility model relates to a structure supporting and retaining a side slope, in particular to a factory prefabricated box-type retaining wall made of reinforced concrete.

Background technique:

During the construction of foundation engineering facilities, maintaining slope stability is an important content, and building retaining walls to support slopes is one of the commonly used methods. There are many forms and types of retaining walls, such as mortar block stone retaining walls, reinforced concrete retaining walls, anchor retaining walls, reinforced soil retaining walls, etc., and the construction of these retaining walls will take a long time. The construction period is relatively short, and these retaining walls will not meet the requirements.

Invention content:

In view of this, the purpose of this utility model is to provide a retaining wall made of prefabricated reinforced concrete boxes, which can avoid the long construction period of traditional retaining walls.

In order to achieve the above object, the technical solution of the utility model is:

The box-type retaining wall of the utility model is characterized in that: it includes several layers of cuboid boxes stacked together, and each layer of box bodies is also composed of several identical boxes side by side, and the width of each box body in each layer is automatically It decreases layer by layer from bottom to top, and the box is filled with sand and soil. The space between the upper and lower boxes and the bottom box and the ground are connected and fixed by piles.

The two sides of the above-mentioned boxes are provided with vertical grooves and vertical ridges, so that two boxes are inserted and fixed through the vertical grooves and vertical ridges.

The top surface of the above-mentioned box body is an opening, and the remaining surfaces are reinforced concrete cast soil slabs.

Above-mentioned box height is 0.5-1.5m, and length and width are 1-2m.

There are 4 holes on the bottom panel of the above-mentioned box body, which are used for piercing and nailing of the cylindrical pile body cast by reinforced concrete.

Two steel bar pull rings are fixed on the top of the above box to facilitate hoisting.

Flowers and plants are planted on the porous soil between the above-mentioned box bodies.

The box body is composed of 5 reinforced concrete slabs, the top surface is an opening, and 4 holes with a diameter of 20 cm are left on the bottom plate to pass through the pile body. There are 2 grooves and 2 holes on both sides of the box body. A convex strip is used to block each other between the adjacent boxes to increase the overall stability. The two steel bar pull rings on the top of the box are used for lifting by a crane; 10mm rebar, surrounded by a cylinder of concrete with tapered ends.

The working principle of the utility model is that the box is filled with soil and compacted, the hole at the bottom of the box is nailed into the pile, the friction between the box and the foundation soil and the friction between the pile and the foundation soil The interaction of the retaining wall together prevents the retaining wall from sliding and overturning; the boxes are stacked layer by layer, and the width of the upper part is slightly smaller than that of the lower part, and the upper part of the box does not cover the soil part of the lower part of the box to plant flowers and plants ,beautify environment.

The retaining wall of the utility model is entirely composed of reinforced concrete components prefabricated in the factory. It only needs to level the site and hoist it with a crane. It has a simple structure, fast construction speed and good stability, and can be applied to slopes such as embankments, river banks, roads and railways. engineering support.

Detailed ways

The box-type retaining wall of the utility model, as shown in Figure 1, comprises several layers of cuboid boxes 1 stacked together, and each layer of boxes is also composed of several identical boxes side by side, and each box width of each layer It decreases layer by layer from bottom to top, and the box is filled with sand 3, and the upper and lower boxes and between the bottom box and the ground are connected and fixed by piles 2.

Both sides of the above-mentioned boxes are provided with vertical grooves 4 and vertical protruding strips 5, so that two boxes can be inserted and fixed through the vertical grooves and the vertical protruding strips.

The top surface of the above-mentioned box body is an opening, and the remaining surfaces are reinforced concrete cast soil slabs.

Above-mentioned box height is 0.5-1.5m, and length and width are 1-2m.

Four holes 6 are provided on the bottom panel of the above-mentioned box body, which are used for piercing and nailing of the cylindrical pile body formed by reinforced concrete casting.

Two steel bar pull rings are fixed on the top of the above box to facilitate hoisting.

Flowers and plants are planted on the porous soil between the above-mentioned box bodies.

During the specific construction, first excavate the foundation pit K at the position of the proposed retaining wall, the depth of the pit is 50cm, and then the crane hooks the steel bar pull rings on both sides of the box body 1, lifts it and puts it into the foundation pit, and lifts the adjacent boxes one by one body 1, so that the grooves 4 and convex strips 5 of two adjacent boxes 1 are locked to each other, and the pile body 2 is nailed into the bottom plate hole 6 of each box body 1, so that the pile body 2 enters the bottom foundation soil layer Inside, fill the soil around the slope into the box 1 and compact it, so far the construction of the first layer of retaining wall is completed; lift the box 1 with a smaller width and the same length as the first layer of retaining wall, Put it on the top of the filling soil of the first layer of retaining wall, and close to the rear of the first layer of boxes, the adjacent boxes 1 are stuck to each other, nailed into the pile 2 and filled and compacted the soil; the same method Construction of the third layer of retaining wall, ... until the design height of the retaining wall; the exposed soil between the upper and lower adjacent two-layer box body 1 can be planted with flowers and plants for greening.

After the utility model is implemented, it has the following obvious benefits:

(1) The construction is simple and fast, all the components of the retaining wall are prefabricated in the factory, and only need to be installed on site, saving time and effort, and can be mass-produced at one time, saving costs; (2) Good stability, the box is nailed by piles It has good anti-skid and anti-overturning properties, and the boxes are locked by grooves and convex strips, and the lateral stability is good; (3) The outlet between the upper and lower adjacent two-layer boxes The soil is exposed, and flowers and plants are planted for greening, so as to avoid the problem of single tone of the traditional retaining wall.
