Tunnel type material (soil) blocking wall and construction method

Abstract

The invention discloses a tunnel type material (soil) blocking wall and a construction method. The structure at least comprises a material (soil) blocking wall bottom plate; two vertical walls are arranged on a bottom plate of the material (soil) blocking wall at intervals; more than one material (soil) blocking wall partition plate is arranged between the two vertical arms at intervals; the material (soil) blocking wall partition plate and the material (soil) blocking wall bottom plate are arranged in parallel. The material (soil) blocking wall bottom plate, the material (soil) blocking wall vertical wall and the material (soil) blocking wall partition plate jointly form a multi-cavity tunnel in the length direction of the material (soil) blocking wall. Due to the arrangement of the double vertical walls, the vertical walls are mainly stressed by pulling force and pressing force (one vertical wall is pulled and the other vertical wall is pressed). The change of the stress form is more beneficial for the reinforcing steel bar and the concrete to exert the performance of respective materials.

Description

Technical Field

[0001] The present invention relates to a tunnel-type retaining wall (for soil) and a construction method thereof. Background Art

[0002] In industrial enterprises, due to production needs, it is often necessary to store a large amount of bulk materials. To save the storage site for materials, it is necessary to increase the stacking height of the bulk materials, which requires a retaining wall to support the bulk materials. In some industrial enterprises, the stacking height of the bulk materials reaches nearly 20 m, and the height of the retaining wall for supporting them also reaches more than 10 m. In the fields of transportation, municipal engineering, etc., in order to obtain more land area, it is often necessary to support the soil mass at the place with height difference on the site, and the support of the soil mass is usually achieved by setting up a retaining wall. In the prior art, the retaining walls usually include the following types: 1. Gravity retaining wall; 2. Cantilever retaining wall; 3. Counterfort retaining wall. The prior art retaining walls have the following different disadvantages: The gravity retaining wall occupies a large area and is not suitable for use when the height of the retaining wall is greater than 8 m; When the height of the cantilever retaining wall is greater than 8 m, the cost will increase significantly; When the height of the counterfort retaining wall is greater than 8 m, it has good economy. From the characteristics of the existing retaining walls, the tall retaining walls for bulk materials in industrial enterprises and the tall retaining walls in the fields of transportation and municipal engineering are preferably the counterfort retaining walls for bulk materials (soil). However, since there are counterforts arranged at intervals behind the wall panels of the counterfort retaining wall for bulk materials (soil), the stored materials between the counterforts cannot be taken out by equipment, forming dead materials, and the counterforts affect the operation of the material-taking equipment. Therefore, the counterfort retaining wall for bulk materials (soil) is not suitable for the tall retaining walls in industrial enterprises. In the fields of municipal engineering and transportation, it is usually necessary to build a road on the top of the counterfort retaining wall, and a large number of various pipelines usually need to be buried under the road. The counterforts of the counterfort retaining wall will affect the laying of various pipelines. Therefore, the use of the counterfort retaining wall in the fields of municipal engineering, transportation, etc. is restricted. Summary of the Invention

[0003] In order to overcome the disadvantages of the prior art, the present invention provides a tunnel-type retaining wall (for soil).

[0004] To achieve the above object, a tunnel-type retaining wall (for soil) of the present invention at least includes:

[0005] A retaining wall (for soil) bottom plate;

[0006] Two vertical walls are arranged at intervals on the retaining wall (for soil) bottom plate;

[0007] One or more retaining wall (for soil) partitions are arranged at intervals between the two vertical walls;

[0008] The retaining wall (for soil) partitions are arranged parallel to the retaining wall (for soil) bottom plate;

[0009] So that the retaining (soil) wall base plate, the retaining (soil) wall vertical wall, and the retaining (soil) wall partition jointly form a multi-cavity tunnel along the length direction of the retaining (soil) wall.

[0010] To achieve the above object, the construction method of the tunnel-type retaining (soil) wall of the present invention includes the following steps:

[0011] 1) Implement the retaining (soil) wall base plate;

[0012] 2) After the retaining (soil) wall base plate reaches a certain strength, implement two first-stage retaining (soil) wall vertical walls in parallel on the retaining (soil) wall base plate, and implement the first retaining (soil) wall partition on the two first-stage retaining (soil) wall vertical walls;

[0013] 3) After the two first-stage retaining (soil) wall vertical walls and the first retaining (soil) wall partition reach a certain strength; implement two second-stage retaining (soil) wall vertical walls and the second retaining (soil) wall partition correspondingly on the first retaining (soil) wall partition.

[0014] 4) And so on until the height of the predetermined requirement is reached.

[0015] A tunnel-type retaining (soil) wall of the present invention uses a multi-cavity tunnel along the length direction of the retaining (soil) wall jointly composed of the retaining (soil) wall base plate, the retaining (soil) wall vertical wall, and the retaining (soil) wall partition as a supporting structure for the material (soil). Compared with the traditional cantilever retaining wall, the tunnel-type retaining (soil) wall changes the stress form of the retaining wall in terms of structural stress. Under the action of the material (soil) pressure, the stress of the vertical wall of the cantilever retaining wall is mainly in the form of bending moment. Due to the setting of the double vertical walls in the tunnel-type retaining (soil) wall, the stress of the vertical wall is mainly in the form of tension and compression (one vertical wall is in tension and the other is in compression). The change in the stress form is more conducive to the respective performance of steel bars and concrete. In terms of construction, the traditional cantilever retaining wall must be constructed by using high formwork support, which is difficult and dangerous to construct. The tunnel-type retaining (soil) wall can be constructed layer by layer with each cavity like constructing an ordinary shear wall building, which is convenient and less dangerous to construct. In terms of use, when the tunnel-type retaining (soil) wall is used in an industrial material yard, its cavity can be used as a pedestrian passage and a passage for industrial pipelines. When used in the municipal and transportation fields, its cavity can be used as a passage for municipal pipelines, having the function of one wall serving two purposes. In terms of cost, through trial calculation, for a 11m-high retaining wall, when using the tunnel-type retaining wall compared with the cantilever retaining wall, the concrete consumption is 54.22% of that of the cantilever retaining wall, the steel bar consumption is 102.8% of that of the cantilever retaining wall, the formwork consumption is 235.74% of that of the cantilever retaining wall, and the total cost is 84.91% of that of the cantilever retaining wall. Therefore, this tunnel-type retaining (soil) wall has the characteristics of wide applicability, reasonable stress, simple structure, convenient construction, and low cost.
