Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an anti-deformation geogrid. Background Art

[0002] Geogrid is a major geosynthetic material. Compared with other geosynthetics, it has unique properties and functions. It is often used as reinforcement for reinforced soil structures or reinforcement for composite materials. Geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, glass fiber geogrids, and polyester warp-knitted polyester geogrids. The grid is a two-dimensional grid or a three-dimensional grid screen with a certain height made of high molecular polymers such as polypropylene and polyvinyl chloride through thermoplasticization or molding. When used in civil engineering, it is called a geogrid. During foundation pit construction, geogrids usually need to be installed in the foundation pit, but geogrids are easily deformed due to soil compression, which affects the use effect. Therefore, an anti-deformation geogrid is proposed to prevent deformation and facilitate construction. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides an anti-deformation geogrid.

[0005] By adopting the above technical solution, the prefabricated baffles are prefabricated in the factory and transported to the site for direct installation. When the base height is ≤600mm, there is no need to set supports on the inner sides of the four prefabricated baffles. It is only necessary to drive multiple support rods at intervals around the bottom of the prefabricated baffles to fix them. The bottom concrete cushion layer is poured later, and the surrounding areas are backfilled with soil after pouring. When the base height is ≥600mm, the bottom ends of the first column and the second column are first buried in the foundation pit, and the surrounding areas are backfilled with soil to fix them. The first layer of prefabricated baffles are inserted into the first column. After the installation is completed in sequence, the second layer of prefabricated baffles are installed. The protrusions and the slots at the bottom of the prefabricated baffles are conducive to the splicing of the upper and lower prefabricated baffles. There is no need to set supports on the inner sides of the first layer of prefabricated baffles. The bottom concrete cushion layer is poured later, and the surrounding areas are backfilled with soil after pouring. This facilitates construction, improves strength and stability, and prevents deformation due to soil compression.

[0006] Specifically, the prefabricated baffles of the first layer are inserted into the inner side of the first column, and adhesive is applied to the top of the prefabricated baffles of the first layer, between the prefabricated baffles and the first column, and between the prefabricated baffles and the second column.

[0007] By adopting the above technical solution and setting the adhesive, the stability of the upper and lower prefabricated baffles after splicing can be improved, and the connection reliability and waterproof effect between the prefabricated baffle and the first column and between the prefabricated baffle and the second column can be improved.

[0008] Specifically, the first column and the second column are both made of concrete, and the embedding depth of the first column and the second column is both 40 mm.

[0009] By adopting the above technical solution, the arrangement of the first column and the second column not only facilitates the installation of the prefabricated baffle, but also improves the overall stability.

[0010] Specifically, the plurality of support rods are made of threaded steel bars with a length of 20 cm and a diameter of 12 mm, and the distance between two adjacent support rods is 1 m.

[0011] By adopting the above technical solution and setting the support rods, the stability of the prefabricated baffle can be improved.

[0012] Specifically, the adhesive is cement epoxy resin mortar or waterproof sealing structural adhesive.

[0013] Specifically, the lateral support member includes a connecting plate, connecting bolts and a support rod. The connecting plate, the first column and the second column are each provided with four screw holes adapted to the connecting bolts. The connecting plate is connected to one end of the support rod. A pad is fixed to the end of the support rod away from the connecting plate. A threaded rod is provided on one side of the support rod. The bottom end of the threaded rod is conical in structure. A screw hole adapted to the threaded rod is provided on the pad.

[0014] By adopting the above technical solution, after the pad is placed in the foundation pit, the threaded rod is rotated and the bottom end of the threaded rod is inserted into the soil, which can improve the stability of the first column and the second column.

[0025] During use, when the pedestal height is ≤600mm, there is no need to set supports on the inner sides of the four prefabricated baffles 1. It is only necessary to drive a plurality of support rods 4 at intervals around the bottom of the prefabricated baffles 1 to fix them. Later, the bottom concrete cushion layer is poured. After pouring, the surrounding area is backfilled with soil; when the pedestal height is ≥600mm, first bury the bottom ends of the first column 3 and the second column 6 in the foundation pit, backfill with soil around them to fix them, insert the end of the first layer of prefabricated baffles 1 into the first column 3, and after the installation is completed, install the second layer of prefabricated baffles 1. The protrusions 2 and the slots at the bottom of the prefabricated baffles 1 are conducive to the splicing of the upper and lower prefabricated baffles 1. There is no need to set supports on the inner side of the first layer of prefabricated baffles 1. Later, the bottom concrete cushion layer is poured. After pouring, the surrounding area is backfilled with soil, which facilitates construction and improves strength and stability.

[0026] In order to improve the strength and sealing of the joints, the prefabricated baffle 1 of the first layer is inserted into the inner side of the first column 3, and adhesive is coated on the top of the prefabricated baffle 1 of the first layer, between the prefabricated baffle 1 and the first column 3, and between the prefabricated baffle 1 and the second column 6.
