[0054] Embodiment 1
[0055] The modular prefabricated assembly provided by the embodiment of the utility model includes a complete prefabricated component 100 and a reinforcement member 200; the complete prefabricated component 100 includes a hollow main body 110, the main body 110 is square, and the four corners of the top surface and the four corners of the bottom surface of the main body 110 are provided with protruding limiting portions 120, and the limiting portions 120 are square; the complete prefabricated component 100 is provided with a first reinforcement hole 121, the first reinforcement hole 121 penetrates the complete prefabricated component 100 along the height direction of the complete prefabricated component 100, and the reinforcement member 200 passes through the first reinforcement hole 121.
[0056] Specifically, see Figure 1 and Figure 2 The complete prefabricated components 100 can be combined to form an integral part of the assembled retaining wall, and the reinforcement 200 can reinforce the complete prefabricated components 100 and the foundation so that the wall itself is connected to the foundation as a whole. Furthermore, the complete prefabricated component 100 can be made of concrete, reinforced concrete or other materials. The complete prefabricated component 100 has a spatial H-shaped structure, is spatially symmetrical, and has the same overall outer contour length, width and height, in the form of a cube. The complete prefabricated component 100 is hollow as a whole, and has eight protruding limit portions 120 on the periphery. A first reinforcement hole 121 is provided in the center of the limit portion 120, through which the reinforcement 200 can pass.
[0057] The complete prefabricated components 100 in the modular prefabricated assembly can be prefabricated in the factory, transported to the construction site after production, and assembled using the reinforcement 200. The first reinforcement hole 121 is used to allow the reinforcement 200 to pass through, so that the reinforcement 200 can be assembled with multiple complete prefabricated components 100 or the complete prefabricated components 100 can be installed on the ground. The complete prefabricated component 100 is square in shape as a whole, and a limiting portion 120 is provided. The multi-layer complete prefabricated components 100 can be limited by the limiting portion 120 for preliminary fixation to form an assembled retaining wall. The complete prefabricated components 100 are prefabricated in the factory, which solves the problem that the technical level of the construction workers affects the quality of the retaining wall; the use of modular prefabricated components can realize assembled construction, and assembled construction can solve the problems of long construction period and high labor consumption. At the same time, the reinforcement member 200 is used to connect two adjacent complete prefabricated components 100, or to connect the complete prefabricated component 100 to the ground, thereby enhancing the strength of the retaining wall, so that it can bear greater geotechnical pressure than conventional retaining walls.
[0058] The following is a detailed description of the shape and structure of the modular prefabricated components:
[0059] In an optional solution of the embodiment of the utility model, the main body 110 is provided with a square hole 111 , the axis of the square hole 111 is colinear with the axis of the main body 110 , and penetrates the main body 110 along the height direction of the main body 110 .
[0060] Specifically, see Figure 1 The cross section of the square hole 111 is set to be square, and is set to be square.
[0061] A square hole 111 is provided at the center of the main body 110 , so that the main body 110 has a hollow structure, and the limiting portion 120 can extend into the square hole 111 for limiting.
[0062] In an optional solution of the embodiment of the utility model, the length, width and height of the limiting portion 120 are equal and are all set to L; the length and width of the main body 110 are equal and are set to 4L, and the height of the main body 110 is set to 2L.
[0063] Specifically, see Figure 1 The specific value of L can be set according to actual needs and is not limited in this practical embodiment.
[0064] The length, width and height of the limiting portion 120 are equal and are all set to L; the length and width of the main body 110 are equal and are set to 4L, and the height of the main body 110 is set to 2L; the complete prefabricated component 100 is realized as a whole in a cubic shape.
[0065] In an optional solution of the embodiment of the utility model, the length and width of the square hole 111 are equal, and both are set to 2L.
[0066] Specifically, the dimensions of the various parts of the complete prefabricated component 100 satisfy a certain proportional relationship, that is, the length, width and height of the limiting portion 120 are the same, all of which are 1 / 4 of the total length of the complete prefabricated component 100, and the net distance between the limiting portions 120 is twice the width of the limiting portions 120. This proportional relationship enables the complete prefabricated component 100 to be fully mosaic-assembled, thereby increasing the integrity and structural strength of the retaining wall.
[0067] The length and width of the square hole 111 are equal, and are both set to 2L; so that the volume of the square hole 111 can match the four limiting parts 120 of the upper layer and the lower layer.
[0068] In an optional solution of the embodiment of the utility model, the length of the reinforcement member 200 is greater than 4L.
[0069] Specifically, in this embodiment, the reinforcement member 200 may be composed of reinforcing bars and bonding materials. The reinforcement member 200 may pass through the first reinforcement hole 121 in the complete prefabricated component 100 to enter the foundation, or multiple complete prefabricated components 100 may be connected and reinforced to form a wall structure of an assembled retaining wall with good bearing capacity. The reinforcement member 200 is embedded in the foundation to provide anchoring force for the assembled retaining wall, which can improve the anti-overturning and anti-slip capabilities of the assembled retaining wall and significantly improve the ability of the assembled retaining wall to withstand horizontal loads. The depth of the reinforcement member 200 embedded in the foundation and the required strength of the reinforcement member 200 itself are determined by the force magnitude of the assembled retaining wall, and are not limited here. The reinforcement bar material of the reinforcement member 200 may be, but not limited to, anchor rods, anchor cables and other materials, and the bonding material may be, but not limited to, concrete mortar, epoxy resin and other anchoring materials. Furthermore, the reinforcing bars are placed in the first reinforcing holes 121 and the foundation boreholes, and the reinforcing bars are connected to the complete prefabricated component 100 and the foundation as a whole by injecting adhesive material into the first reinforcing holes 121 and the boreholes.
[0070] The length of the reinforcement member 200 is greater than 4L, so that both ends of the reinforcement member 200 can extend out of the complete prefabricated component 100 to achieve the reinforcement function.
[0071] In an optional solution of the embodiment of the utility model, the horizontal cross-section of the reinforcement member 200 is set to be circular, and the cross-section of the first reinforcement hole 121 is correspondingly set to be circular.
[0072] Specifically, the diameter of the first reinforcement hole 121 is equal to the diameter of the reinforcement member 200 .
[0073] The cross section of the first reinforcement hole 121 is set to be circular, which is convenient for processing and manufacturing.
[0074] In an optional solution of the embodiment of the utility model, the four limiting parts 120 located on the top surface of the main body 110 are all provided with a first reinforcement hole 121 .
[0075] Specifically, the first reinforcement hole 121 passes through from the limiting portion 120 located on the top surface of the main body 110 to the limiting portion 120 correspondingly located on the bottom surface of the main body 110. Figures 11 to 15 The complete prefabricated components 100 and the reinforcements 200 can be flexibly assembled to form assembled retaining walls of various shapes according to different application scenarios and needs, including but not limited to retaining walls with trapezoidal and rectangular cross-sections, which can meet the support needs of various engineering rock and soil bodies; compared with traditional masonry retaining walls, the assembled retaining walls formed by the complete prefabricated components 100 and the reinforcements 200 have the advantages of modular manufacturing components, high construction efficiency, small and high strength walls, strong anti-overturning and anti-slip capabilities, and adaptability to a wide range of scenarios, and have great application value in the field of geotechnical engineering support and protection.
[0076] A plurality of first reinforcement holes 121 are provided to enhance the connection strength.
[0077] Embodiment 2
[0078] The assembled retaining wall provided in the embodiment of the utility model includes the modular prefabricated components described in the first embodiment, and therefore also includes all the beneficial effects in the first embodiment, which will not be described in detail here.
[0079] In an optional scheme of an embodiment of the utility model, the assembled retaining wall includes a plurality of modular prefabricated components; the complete prefabricated components 100 in the plurality of modular prefabricated components are arranged in multiple layers, and each layer includes a plurality of closely arranged complete prefabricated components 100; each layer of complete prefabricated components 100 is staggered and alternated, and the four limiting portions 120 of the complete prefabricated components 100 of the upper layer are respectively embedded in the square holes 111 of the four adjacent complete prefabricated components 100 of the lower layer.
[0080] Specifically, see Figures 8 to 10 Each layer is staggered and alternated, and one quarter of each of the four adjacent main bodies 110 of the previous layer is just embedded in the hollow part of a main body 110 of the next layer, and the first reinforcement holes 121 of the multi-layer complete prefabricated components 100 are correspondingly connected; an assembled retaining wall is formed according to the height and width requirements.
[0081] The multi-layered complete prefabricated components 100 and the reinforcement members 200 form an assembled retaining wall.
[0082] In an optional solution of the embodiment of the utility model, the assembled retaining wall further includes an incomplete prefabricated component 300 , and the incomplete prefabricated component 300 is used for plugging and matching with the complete prefabricated component 100 .
[0083] Specifically, see Figures 3 to 7The incomplete prefabricated component 300 is a part of the complete prefabricated component 100 and can have various forms according to different segmentation methods.
[0084] The complete prefabricated components 100 and the incomplete prefabricated components 300 are combined to form an assembled retaining wall with a solid wall body and a flat wall surface.
[0085] In an optional solution of the embodiment of the utility model, the incomplete prefabricated component 300 includes an embedded part and a reinforcement part, the embedded part is connected to the reinforcement part, and the reinforcement part is provided with a second reinforcement hole 310.
[0086] Specifically, the embedding part and the reinforcement part are integrally formed, and the reinforcement member 200 extends into the second reinforcement hole 310. The incomplete prefabricated component 300 is used as a matching component when the complete prefabricated component 100 is assembled to form a retaining wall, that is, in a specific case, to fill the space left after the complete component is inlaid and assembled, so that the retaining wall is full and the wall surface is flat. Under the condition that the proportional relationship of the sizes of the various parts of the prefabricated component is met, the size and material of the prefabricated component can be determined according to the force required for the retaining wall.
[0087] The embedding portion is used to be embedded in the gap of the wall constructed by a plurality of complete prefabricated components 100 , and the reinforcing member 200 is used to be connected with the reinforcing member 200 .
[0088] The following is a detailed description of the construction steps of the prefabricated retaining wall:
[0089] Step S1: prepare the retaining wall foundation in advance and anchor the reinforcement member 200 according to the spacing of the first reinforcement holes 121;
[0090] Step S2: insert the main body 110 of the first layer into the reinforcement member 200 through the first reinforcement hole 121, and install the main body 110 of the second layer in the same manner as the two adjacent layers of complete prefabricated components 100;
[0091] Step S3: Repeat step S2 to finally form the required height;
[0092] Step S4: Fill the first reinforcement hole 121 with the setting material until the final setting is completed.
[0093] More specifically:
[0094] (1) Factory prefabricated components. Factory prefabricated components adopt modular sizes to facilitate production and on-site assembly. The dimensions of each part of the complete prefabricated component 100 meet a certain proportional relationship, that is, the length, width and height of the limiter 120 are the same, all of which are 1 / 4 of the total length of the complete prefabricated component 100, and the net distance between the limiters 120 is twice the width of the limiter 120. The specific dimensions are determined according to the requirements of the prefabricated retaining wall. Considering the needs of assembly and hoisting transportation, the dimensions of the complete prefabricated component 100 and the incomplete prefabricated component 300 should not be too large. The proportional relationship of the dimensions of each part of the incomplete prefabricated component 300 must meet the proportional relationship of the dimensions of each part of the complete prefabricated component 100, and the specific dimensions consistent with the latter are adopted. If required, both the complete prefabricated component 100 and the incomplete prefabricated component 300 can be made of concrete and steel mesh (or steel cage), and the amount of steel mesh (or steel cage) is determined according to different bearing capacities.
[0095] (2) Site foundation preparation. If it is not necessary to anchor the foundation with the reinforcement member 200 to increase the anti-overturning and anti-slip capabilities of the retaining wall, the retaining wall foundation only needs to level the site, compact the foundation, and meet the foundation bearing capacity. When it is necessary to anchor the foundation with the reinforcement member 200, it is necessary to drill holes according to the designed position (the position of the first reinforcement hole 121 of the limiter 120) after leveling the site and compacting the foundation. The diameter and depth of the drill hole are determined according to the required anchoring force, see Fig.16 In the middle A.
[0096] (3) On-site modular prefabricated component assembly. According to the retaining wall design, the first layer of prefabricated components is assembled first. The first reinforcement hole 121 of the prefabricated component limiter 120 should be aligned with the foundation drill hole, see Fig.16 At B in the middle. After that, all the prefabricated components on the upper part are assembled, and the retaining wall is Fig.16 Center C.
[0097] (4) Construction of reinforcement member 200. After the prefabricated components of the retaining wall are assembled, reinforcing bars (anchor rods, anchor cables, etc.) are placed in the first reinforcement holes 121 and the foundation holes according to the design, and bonding materials (concrete mortar, etc.) are injected into the first reinforcement holes 121 and the foundation holes as required, see Fig.16 In the middle D.
[0098] (5) Complete the construction. For the reinforcement materials that are bonded to the entire length, cut them off and take anti-corrosion measures on the top. For the reinforcement materials that are anchored at the ends, anchor them at the ends and take anti-corrosion measures. Fig.16 Middle E.
[0099] For large-scale prefabricated assembled retaining walls, segmented construction can be adopted.
[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
