Description

Technical Field

[0001] This utility model relates to the field of support structure technology, and in particular to a support structure combining H-beams and prefabricated retaining plates. Background Technology

[0002] In urban infrastructure construction, pipeline laying, renovation, and maintenance are common types of projects. In particular, when the project involves traffic facilities, existing structures, underground pipelines, etc. in the built-up area, support measures are often required to ensure the safe implementation of the project and reduce the impact on the surrounding environment.

[0003] The selection of support methods should comprehensively consider factors such as construction conditions, surrounding environment, engineering geology, pit dimensions, and load conditions. Among them, steel structure support methods are widely used in pit support due to their advantages such as a wide variety of types, ease of combination, convenient construction, and reusability.

[0004] When the retaining piles are spaced out, attention should be paid to protecting the soil between the piles to prevent soil erosion from affecting the safety of the foundation pit and the surrounding environment. For example, CN201810282650.8 discloses a composite retaining pile wall consisting of retaining piles, a retaining wall, and a pile foundation. The pile foundation is connected to the retaining wall via a pile cap, and the retaining piles are further connected to the retaining wall via a connecting beam, forming a composite retaining pile wall structure. The retaining piles transfer their horizontal bearing capacity to the retaining wall through the connecting beam, effectively improving the overturning and sliding resistance of the buttress-type retaining wall. The pile foundation bears the vertical load transferred from the upper retaining wall through the pile cap, effectively controlling settlement deformation. For example, CN03113876.4 relates to a soil support structure, the purpose of which is to avoid the use of reinforced concrete in retaining walls and reduce project costs. The steps include: forming a retaining support structure with cement-soil pile walls and ground anchors, which can be combined into A-frame, portal frame, multi-row anchored, and soil-retaining platform types as needed. CN201210102998.7 relates to a deep foundation pit support structure, including soil nailing retaining piles attached to the sidewall of the foundation pit. A water-stopping support pile row with one end embedded in the soil below the foundation pit is provided on the outside of the soil nailing retaining piles. A horizontal anti-lateral capping beam is provided in the middle of the water-stopping support pile row, and anti-lateral reinforcement pile row is provided below the anti-lateral capping beam. This deep foundation pit support structure retains soil by attaching soil nailing retaining piles to the sidewalls of the foundation pit. The water-stopping support piles support the soil nailing retaining piles while preventing water seepage. Further reinforcement piles are installed on the outside of the water-stopping support piles to provide additional support for the soil nailing retaining piles and the water-stopping support piles. This effectively ensures the strength of the support structure and provides better and safer protection for the deep foundation pit.

[0005] However, the existing support structure is not convenient enough to operate and needs to be improved to meet better usage requirements. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings and defects of existing technologies by providing a support structure combining H-beams and prefabricated retaining plates. This support structure combining H-beams and prefabricated retaining plates is easy to process, the size of the retaining plates can be flexibly adjusted according to actual conditions to meet engineering requirements, and the retaining plates can be reused, thus exhibiting good economic efficiency.

[0007] This utility model is implemented as follows:

[0008] A support structure combining H-beams and prefabricated retaining plates includes prefabricated retaining plates and supports for assembling the prefabricated retaining plates together. There are at least two supports arranged relatively apart. Positioning grooves are formed on two sides along the length of each support. The two ends of the prefabricated retaining plates are engaged in the two opposite positioning grooves of the two supports and assembled together with the supports.

[0009] As one embodiment, there are multiple prefabricated retaining walls, and the multiple prefabricated retaining walls have the same structure and size.

[0010] As one embodiment, the prefabricated retaining plate is a rectangular plate.

[0011] As one embodiment, the prefabricated retaining plate has at least two perforated steel blocks on one side along its length, arranged at intervals.

[0012] As one embodiment, the prefabricated retaining plate consists of two front panels and an end plate that connects the front and rear panels at both ends.

[0013] As one embodiment, the end plate is a channel steel with a U-shaped groove structure on the inner side and a flat surface on the outer side.

[0014] In one embodiment, the bracket is composed of H-beams and angle steel connected together. There are two angle steels, which are symmetrically fixed to the two sides of the web of the H-beams and arranged near one end of the H-beams.

[0015] As one embodiment, a positioning groove is formed between each angle steel and the end plate of the corresponding H-beam.

[0016] As one embodiment, the angle steel is welded and fixed to the H-beam, so that the positioning slot forms a structure with a fixed slot width.

[0017] As one embodiment, the angle steel and the H-beam are fixed by bolts with adjustable positions, so that the positioning slot forms a structure with variable slot width.

[0018] This utility model presents a support structure combining H-beams and prefabricated retaining walls. The positioning grooves formed between the angle steel and the flanges of the H-beams facilitate the positioning and installation of the retaining walls, enhancing the convenience of construction. As the foundation pit is excavated layer by layer, the retaining walls can automatically sink under their own weight, achieving real-time protection of the soil between piles and improving the safety of the foundation pit.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0026] See Figures 1 to 4 As shown in the exemplary embodiment of this application, the support structure combining H-beams and prefabricated retaining plates includes prefabricated retaining plates 1 and brackets for assembling the prefabricated retaining plates together. There are at least two brackets arranged relatively apart. Positioning slots are formed on two sides along the length direction of the brackets. The two ends of the prefabricated retaining plates 1 are engaged in the two opposite positioning slots of the two brackets and assembled together with the brackets.

[0027] In one embodiment, there are multiple prefabricated retaining plates 1, and the multiple prefabricated retaining plates have the same structure and size. In one embodiment, the prefabricated retaining plate is a rectangular plate. In one embodiment, one side of the prefabricated retaining plate along its length has at least two perforated steel blocks 4, arranged at intervals. In one embodiment, the prefabricated retaining plate consists of two front panels and end plates connecting the front and rear front panels at both ends. The front panels are steel plates of a certain thickness. In one embodiment, the end plates are channel steel, with a U-shaped channel structure on the inner side and a flat surface on the outer side, and they are welded together.

[0028] In one embodiment, the support is constructed by connecting H-beams 2 and angle steels 3. Two angle steels are symmetrically fixed to both sides of the web of the H-beams, with one end closer to the H-beam. In another embodiment, each angle steel forms a positioning groove with the corresponding end plate of the H-beam, the width of which is adapted to the thickness of the prefabricated retaining plate.

[0029] As one implementation, the angle steel and the H-beam are welded together to form a fixed-width positioning groove. Alternatively, welding can be omitted, and bolts can be used to connect the angle steel and the H-beam. Figure 1 As shown. In one embodiment, the angle steel and the H-beam are fixed together by adjustable bolts, creating a variable-width positioning groove. Specifically, an adjustment hole can be made on the web of the H-beam, and a fixing hole can be made at the connection between the angle steel and the H-beam. The H-beam and the angle steel can be locked together with bolts. The adjustment hole can be an oblong hole. After adjustment, the angle steel is locked with bolts, thus adapting to the assembly needs of prefabricated retaining walls of different thicknesses. Multiple adjustment holes can also be arranged evenly, and one hole can be selected for bolt connection to fix the angle steel and the H-beam as needed.

[0030] In some embodiments, the upper and lower ends of the prefabricated retaining plate 1 can also be made with a convex-concave structure, such as the lower end of the prefabricated retaining plate 1 being a groove and the upper end being a corresponding boss. This allows the prefabricated retaining plates 1 to be inserted together when they are vertically connected, and no large gaps will be formed between the two prefabricated retaining plates 1.

[0031] In an exemplary embodiment of this application, the support structure combining H-beams and prefabricated retaining plates can be manufactured and used in the following manner (taking the positioning slot forming a fixed slot width structure as an example).

[0032] 1. An angle steel is installed on each side of the web of the H-beam, and a positioning groove is formed between the angle steel and the flange of the H-beam. The angle steel and the H-beam are connected by welding.

[0033] 2. Channel steel is installed at the top and bottom of the retaining plate, and the panel is made of steel plate. The steel plate is tightly attached to the flange of the channel steel and connected by welding.

[0034] 3. Arrange square steel blocks on top of the retaining wall, with holes in the middle of the blocks for hoisting, positioning, and installation.

[0035] 4. Insert H-beams with angle steel at intervals into the ground. After the foundation pit has been excavated to a certain depth, insert the first retaining plate into the positioning slot.

[0036] 5. As the foundation pit is excavated layer by layer, the retaining plates gradually move down and are inserted one by one from the top of the positioning slots.

[0037] This utility model presents a support structure combining H-beams and prefabricated retaining walls. The positioning grooves formed between the angle steel and the flanges of the H-beams facilitate the positioning and installation of the retaining walls, enhancing the convenience of construction. As the foundation pit is excavated layer by layer, the retaining walls can automatically sink under their own weight, achieving real-time protection of the soil between piles and improving the safety of the foundation pit.
