Retaining wall

Abstract

The invention provides a retaining wall. Each building block is provided with two anchoring hole sets which are distributed left and right. Each anchoring hole set at least comprises an up-down through hole (2) and connecting holes (3) used for arranging anti-corrosion rods (4). The base (1) is connected with the anti-corrosion rods (4) used for connecting the through holes (2). A staggered distribution structure is adopted between every two adjacent building block layers. A piece of geotechnical cloth (6) laid along the retaining wall surface is arranged between the retaining wall surface and a backfilling body (5). A plurality of geogrids (7) are sequentially arranged in the retaining wall height direction from bottom to top. Each geogrid (7) is arranged between two corresponding up-down adjacent building block layers in a clamped mode, and all the geogrids (7) all extend into the backfilling body (5). Pieces of geotechnical cloth (6) are all arranged between the lowest geogrid (7) and the base (1) as well as between all the up-down adjacent geogrids (7). The retaining wall has the advantages that stability of the retaining wall can be guaranteed while construction convenience is improved.

[0002] The Chinese invention patent application with the application publication number CN 102322040 A discloses a kind of ecological prefabricated block revetment, and its technical scheme is "the upper part of the revetment is made of plant-type cavity block Dry laying The lower part of the revetment is made of fish nest cavity blocks Dry laying formed; the plant-type cavity blocks are built into step-wise For revetment, the plant-type cavity block is provided with a cavity that penetrates up and down, and the cavity of the plant-type cavity block is filled with soil material, and plants are planted in the soil material; the fish nest type The cavity block is provided with a through cavity along the direction of water flow, and a hole is provided on the water side; the fish nest type cavity block and the plant type cavity block are both made of permeable concrete or impervious When the cavity block is made of impermeable concrete, a water-permeable hole is provided on the backwater surface", although the idea of ​​the fish nest block at the bottom and the planting block at the top is disclosed, As a result, the revetment has the advantages of both fish farming and planting plants, but it basically does not have the ability to resist soil pressure, and the ability to resist the impact of water flow is also weak, such as image 3 , once the soil layer attached to the right side of each block moves to the left, the revetment cannot stop the movement of the soil at all, and revetment instability is very easy to occur. Trying to keep the soil layer stable through the gravity of the blocks, but it is obviously useless under the strong soil pressure. Therefore, the bank revetment is ideal according to the current disclosure. The stability and durability of the bank revetment are extremely poor, and it does not have Engineering significance, in addition, this judgment can also be confirmed from another angle, that is, according to the content disclosed in the application specification, the revetment adopts dry-laying, and it can be seen from paragraph 0023 of the specification that the dry-laying mentioned is "do not use cement slurry seat "Building concrete cavity prefabricated blocks in a row", that is to say, simple stacking without using cement slurry as a binder, so the lateral bearing capacity of the revetment is imaginably fragile

[0003] The Chinese invention patent application with the application publication number CN 103993580 A discloses a river retaining wall, and its technical solution is "a river retaining wall, including a base plate, a single block and a cover plate, and a through hole is opened in the middle of the single block. The cavity, the retaining surface and appearance surface of the through cavity and the inner side of the cover plate are respectively provided with vertically downward anchor holes or anchor grooves, and the cover plate and block monomers are stacked on the base plate from top to bottom in sequence. The inner surface of the block monomer and the cover plate are flush with and perpendicular to the base plate, and the corresponding anchor holes or anchor grooves on the retaining surface of the block monomer and the cover plate penetrate up and down and are perpendicular to the base plate. The corresponding anchor holes or anchor grooves on the appearance surface respectively penetrate up and down and are perpendicular to the base plate, respectively insert steel bars into the penetrated anchor holes or anchor grooves and then pour concrete.” The core purpose of this application is to “make the structure more secure and stable, The earth pressure resistance and pullout resistance of the retaining wall are doubled, and the service life is long, especially suitable for water conservancy and flood control projects, large rivers, and large rivers. There are great deficiencies in aspects and operability of construction. Specifically, in terms of ecology, this application only realizes the planting considerations of plants, and the specific details of block 4 (block monomer C4) are disclosed by this application. As can be seen from the structure, although the plants can obtain moisture and nutrition of the soil layer from the opening 44, if the plants want to expose the wall surface, they can only get out from the opening of the cover plate 5 on the top surface or the seam left by the wall, especially the seam. drilled out, such as Figure 1-2 As shown, the growth of plants is greatly restricted, and it is impossible for plants to form multi-level coverage in the vertical direction of the wall; in terms of construction operability, it can be seen from the structure of the application that "the cover plate and the single block Stacked on the base plate from top to bottom, the inner surface of the block monomer and the cover plate are flush and perpendicular to the base plate, and the corresponding anchor holes or anchor grooves on the retaining surface of the block monomer and the cover plate penetrate up and down And perpendicular to the base plate, the corresponding anchor holes or anchor grooves on the appearance surface of each layer of block monomer are respectively penetrated up and down and perpendicular to the base plate, and the anchor holes or anchor grooves after penetration are respectively inserted into steel bars and then poured with concrete. , needs to meet various verticals, the purpose is to adjust the alignment of the upper and lower anchor holes or anchor grooves of each layer, and then insert a whole connecting steel bar from top to bottom and then pour concrete, because the retaining wall is composed of multi-layer block layers Stacked, as attached to the application specification figure 1 , 2 As shown, the blocks 2, 3, and 4 are all three layers, and the steel bar 12 needs to pass through nine layers to realize the connection and fixation of these nine layers, which leads to problems in actual construction. First, the dimensions of each component are required to be accurate , and then requires the construction personnel to stack very accurately, which is time-consuming and labor-intensive, and due to the accumulated errors and the influence of the actual construction environment, the alignment of the anchor holes or anchor grooves is not ideal, so the reinforcement is not easy to insert, even if it is inserted After the reinforcement, the concrete is not easy to pour in, the construction is very inconvenient, time-consuming and laborious, and the construction quality is difficult to be guaranteed, which leads to hidden dangers in the stability of the entire retaining wall
