Description

TECHNICAL FIELD

[0001] The utility model relates to civil engineering technical field, concretely is a brick - gabion - geogrid combined formula reinforced earth retaining wall. BACKGROUND

[0002] In the civil engineering field, the retaining wall is an indispensable structure, which is widely used in many engineering fields such as roads, railways, water conservancy, buildings, mines and urban infrastructure. Its main function is to resist lateral soil pressure, prevent soil collapse, landslide or deformation due to its own gravity or external load, so as to ensure the stability and safety of the engineering structure and the integrity of the surrounding environment.

[0003] In the early engineering practice, people often use some original methods to achieve the support and protection of the soil. For example, using natural topography, simply cutting or filling the slope to achieve the purpose of stabilizing the soil. However, this method is only suitable for the case where the terrain is relatively favorable and the soil pressure is small. For many complex geological and topographical conditions, its limitations will be highlighted.

[0004] With the development of society and the demand of engineering construction, the utilization of land resources is increasingly sufficient, and more engineering projects need to be carried out in areas with large terrain undulations and complex geological conditions. This leads to the need for large-scale filling or excavation of soil during construction, which poses a serious challenge to the lateral stability of the soil. The traditional simple treatment method cannot meet the requirements of engineering safety and quality, so various types of retaining walls have emerged.

[0005] The height of the traditional gabion retaining wall is limited, usually not more than 8 meters, and the recommended height is below 6 meters. Under extreme conditions such as high intensity earthquakes, its stability faces great challenges, and it is difficult to meet the needs of complex engineering environments. Therefore, it is of great significance to develop a reinforced earth retaining wall structure with wider application range and higher stability. UTILITY MODEL CONTENTS

[0006] The utility model aims at providing a brick-gabion-geogrid combined reinforced earth retaining wall to solve the problems in the above background technology.

[0007] In view of the above problems, the technical scheme provided by the utility model is:

[0008] A brick-gabion-geogrid combined reinforced soil retaining wall, comprising a steel reinforcement cage, the steel reinforcement cage being a cube, the steel reinforcement cage comprising six groups of steel reinforcement meshes, the six groups of steel reinforcement meshes constituting six faces of the steel reinforcement cage; the steel reinforcement mesh comprising a square frame, a plurality of horizontal rods and a plurality of vertical rods, the plurality of horizontal rods being distributed equidistantly in the interior of the square frame in the longitudinal direction, the plurality of vertical rods being distributed equidistantly in the interior of the square frame in the transverse direction; a connecting piece, the connecting piece connecting adjacent steel reinforcement meshes together; a geogrid, the geogrid being laid on the ground, a plurality of the steel reinforcement cages being installed on the geogrid.

[0009] Further, the square frame is made of a smooth round steel rod with a diameter of 12 mm.

[0010] Further, the horizontal rods and the vertical rods are made of smooth round steel rods with a diameter of 8 mm.

[0011] Further, the connecting piece is made of a smooth round steel rod with a diameter of 8 mm and is in a spiral shape, the connecting piece being wound on the abutting edges of adjacent square frames, the connecting piece serving to tightly connect adjacent steel reinforcement meshes together. By being wound on the abutting edges of adjacent square frames, the connecting piece enhances the structural integrity of the steel reinforcement cage as a whole, prevents displacement or separation of the steel reinforcement meshes during use, and ensures the stability of the steel reinforcement cage.

[0012] Further, the square frame at the bottom of the steel reinforcement cage is fixed on the geogrid by lashing.

[0013] Further, the geogrid is a steel-plastic geogrid and serves as a basic support structure laid on the ground. A plurality of the steel reinforcement cages are installed on the geogrid, and the square frame at the bottom of the steel reinforcement cage is fixed on the geogrid by lashing, so that the steel reinforcement cage and the geogrid form an organic whole. The geogrid can effectively disperse the soil pressure and enhance the stability of the whole retaining wall structure, and works together with the steel reinforcement cage to jointly bear various loads from the filled soil and the outside.

[0014] Further, the size of the steel reinforcement cage is adapted to the filled bricks.

[0015] Compared with the prior art, the utility model has the advantages that:

[0016] 1. The design of the cubic steel reinforcement cage and the reasonable distribution of the steel reinforcement inside the steel reinforcement cage, in combination with the connecting mode of the spiral connecting piece, make the steel reinforcement cage itself have strong rigidity and stability, can effectively resist lateral soil pressure and other external forces, and reduce the risk of deformation.

[0017] 2. The modular design of the reinforcement cage and the relatively simple connection mode (such as wire fixing) with the geogrid make the construction process more simple and efficient, which can shorten the construction period and reduce the construction cost;

[0018] 3. The different parts of the reinforcement cage are made of round steel bars with different diameters, and the geogrids with appropriate materials are selected, which fully play the mechanical properties of the materials and realize the reasonable use of the materials under the premise of ensuring the structural performance, thereby reducing the engineering cost;

[0019] 4. The combined reinforced soil retaining wall can adapt to different soil conditions and engineering environments, and through adjusting the size of the reinforcement cage, the spacing of the steel bars and the parameters of the geogrid, various engineering requirements can be met, and the combined reinforced soil retaining wall has strong universality.

Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Please refer to Figure 1 - Figure 3The utility model provides a technical scheme: a brick - gabion - geogrid combined formula reinforced earth retaining wall, including reinforced cage 100, reinforced cage 100 is cubic, and reinforced cage 100 includes six groups of steel mesh, and six groups of steel mesh form six faces of reinforced cage 100, and the steel mesh includes square frame 1001, a plurality of horizontal rods 1002, a plurality of vertical rods 1003, a plurality of horizontal rods 1002 are longitudinally distributed in the inside of square frame 1001 at equal distance, a plurality of vertical rods 1003 are transversely distributed in the inside of square frame 1001 at equal distance, connecting piece 200, connecting piece 200 connects adjacent steel mesh together, geogrid 300, geogrid 300 is laid on the ground, and the reinforced cage 100 is set to a plurality of, and a plurality of reinforced cage 100 is installed on geogrid 300.

[0026] Wherein, square frame 1001 is made of diameter 12 millimeter's plain round steel, horizontal rod 1002, vertical rod 1003 are made of diameter 8 millimeter's plain round steel, connecting piece 200 is made of diameter 8 millimeter's plain round steel, and is spiral, and connecting piece 200 is wound on the edge of adjacent square frame 1001.

[0027] Specifically, the bottom square frame 1001 of the reinforced cage 100 is fixed on the geogrid 300 by wire tying, and the geogrid 300 is a steel-plastic geogrid, and the size of the reinforced cage 100 is matched with the filled brick.

[0028] In a certain road slope protection engineering, the brick-gabion-geogrid combined reinforced earth retaining wall of the utility model is used.

[0029] Firstly, according to the engineering design requirement, the size of the reinforced cage 100 is determined as 2 meters long, 2 meters wide and 1.5 meters high, and the steel mesh is processed according to the size. The square frame 1001 is made of diameter 12 millimeter's plain round steel, and the horizontal rod 1002 and the vertical rod 1003 are arranged uniformly in the frame at an interval of 0.2 meters, and are connected into a firm steel mesh by spot welding. Six pieces of steel mesh are prepared in this way, then five groups of steel mesh are connected into a reinforced cage 100 by using diameter 8 millimeter's spiral connecting piece 200, and the prepared reinforced cage 100 has an opening for placing brick.

[0030] The geogrid 300 is made of the reinforcing bar meeting the engineering strength requirement, and is laid on the ground after being leveled and compacted. Then, the prepared reinforced cage 100 is transported to above the geogrid 300, the square frame 1001 of the bottom surface of the reinforced cage 100 is aligned with the geogrid 300, and the opening is ensured to face upward, and the two are tightly fixed together by wire tying.

[0031] Fill the steel reinforcement cage 100 with bricks of appropriate size, and make sure that the bricks are arranged closely and neatly during the filling process, so as to fully exert the load bearing capacity of the steel reinforcement cage 100 and enhance the overall rigidity of the wall. Finally, cover the opening with the remaining piece of steel mesh, and fix it to the steel reinforcement cage 100 by using the connecting member 200.

[0032] Repeat the above steps to fix a certain number of steel reinforcement cages 100 on the geogrid 300, and fill them with bricks.

[0033] During the construction process, strictly follow the design specifications and construction technology, and conduct quality inspection on each connecting part and construction link. After a period of use and observation, the reinforced earth retaining wall is stable in structure, and does not show obvious deformation and damage phenomenon when bearing the soil pressure and external environmental influence, effectively ensuring the safety and stability of the road slope, proving the feasibility and effectiveness of the utility model in practical engineering.

At the same time, the spacing and strength parameters of the tensile reinforcement of the geogrid 300 are adjusted to adapt to the smaller engineering scale and the relatively weak soil bearing capacity. The construction process is similar to the above-mentioned road slope protection project. During the use process after the construction is completed, the retaining wall also shows good stability, meets the retaining requirements of the construction site, and further verifies the applicability and adjustability of the utility model.
