Description

Technical Field

[0001] The invention relates to the technical field of underground support anchoring, and in particular to an underground support anchoring structure for building construction. Background Art

[0002] Anchor support is a kind of active reinforcement and stabilization technology for rock and soil. The anchor rod (cable) as its main technical body has one end anchored into the stable soil (rock) mass and the other end connected to various forms of support structures. Through the tensile action of the rod body, the potential energy of deep strata is called upon to achieve the purpose of stabilizing the foundation pit and the building.

[0003] The invention with the existing authorization announcement number CN213390228U discloses a prestressed steel rod structure for supporting crane beams on rock walls of underground factories, including an anchor pier head, a tensioning section and an anchoring section through which steel rods are passed. The steel rods in the tensioning section are wrapped with factory pre-grouting, plastic corrugated sleeves, plastic smooth sleeves and on-site cement grouting from the inside to the outside, and the steel rods in the anchoring section are wrapped with factory pre-grouting, plastic corrugated sleeves and on-site cement grouting from the inside to the outside.

[0004] Although the above-mentioned technical scheme can effectively solve the problems such as the difficulty in forming the rock platform of the rock wall crane beam under soft rock geological conditions, the long-term creep of the rock mass, and the difficulty in ensuring that the support form of ordinary mortar anchor rods can form an integral force structure for the rock wall crane beam and the side wall rock mass, so that the rock wall crane of the underground powerhouse of the hydropower project under soft rock geological conditions can operate safely and stably, the diagonal brace anchor rods of the above-mentioned technical scheme are difficult to adapt to the grip in different geological environments. If the geological soil is relatively loose and sandy, the poured concrete is difficult to solidify due to the high water content. If the concrete hardness standard cannot be met, the strength of the diagonal brace anchor rod will be greatly reduced. Therefore, technical personnel in this field provide an underground support anchor structure for construction to solve the problems raised in the above-mentioned background technology. Summary of the invention

[0005] In view of this, it is necessary to provide an underground support anchoring structure for construction to solve the problem that concrete is difficult to achieve ideal strength under geological conditions with high water content.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] See also Figures 1 to 4 The present invention provides an underground support anchoring structure for construction, comprising a storage tube 1, six filter tubes 2 are threadedly connected to the inner wall of the storage tube 1, two fastening rings 3 are threadedly connected to the outer surface of each filter tube 2, and the side surfaces of each group of fastening rings 3 close to each other are in contact with the outer surface of the storage tube 1, a sponge 4 is fixedly connected to the inner wall of each filter tube 2, a primary filter cotton 5 is fixedly connected to the inner wall of each filter tube 2, a secondary filter cotton 6 is fixedly connected to the inner wall of each filter tube 2, a tertiary filter cotton 7 is fixedly connected to the inside of each filter tube 2, two threaded plugs 8 are threadedly connected to the outer surface of each filter tube 2, a ground nail tube 9 is fixedly connected to the bottom surface of the storage tube 1, and four penetration holes 10 are opened on the outer surface of the ground nail tube 9.

[0019] The storage tube 1 is used to store water that seeps underground. When used in conjunction with six filter tubes 2, the water that seeps from the bottom can be diverted into the interior of the storage tube 1. The dense holes on the surface of the threaded plug 8 and the sponge 4 can isolate larger stones and clods of earth. The multi-layer filtration of the primary filter cotton 5, the secondary filter cotton 6 and the tertiary filter cotton 7 ensures that sewage cannot enter the interior of the storage tube 1, and prevents the filter tube 2 from being blocked and losing its continuous water absorption function. The cooperation of the storage tube 1 and the filter tube 2 can achieve the purpose of sustainable absorption of underground seepage water, prevent excessive seepage from affecting the solidification of the concrete above, and avoid the effect of moisture on the quality of the concrete.

[0020] Furthermore, a baffle 11 is fixedly connected to the upper surface of the storage tube 1, and twelve limiting rods 12 are fixedly connected to the inner wall of the baffle 11. The baffle 11 is used to connect the upper and lower parts. The twelve limiting rods 12 can be used to install the extended edge of the baffle 11 to increase the resistance of the baffle 11.

[0021] Furthermore, a movable plate 13 is movably hinged on the outer surface of each limiting rod 12, and each movable plate 13 is located inside the baffle 11. The limiting rod 12 is used to limit the movable plate 13, so that the movable plate 13 can freely adapt to the angle inside the baffle 11, thereby increasing the friction between the storage tube 1 and the pit.

[0022] Furthermore, three support rods 14 are fixedly connected to the upper surface of the baffle 11, and three tightening rings 15 are fixedly connected to the outer surfaces of the three support rods 14. The three support rods 14 and the three tightening rings 15 are welded and assembled into an outer ring frame to play a role of overall support.

[0023] Furthermore, a thin plate 16 is provided above the baffle 11, and a plurality of leakage holes 17 are provided on the outer surface of the thin plate 16. The bottom surface of the thin plate 16 is in contact with the upper surface of the baffle 11. The poured concrete can be gathered by the thin plate 16 to ensure the integrity of the entire pillar. Part of the concrete leaks out from the leakage holes 17 to fill the gap between the pit and the support rod 14, thereby achieving external caulking to adapt to the pit, increasing friction and load-bearing capacity. The internal main body is cylindrical to ensure integrity and durability.

[0024] Furthermore, a steel ring 18 is provided inside the thin plate 16, and the bottom surface of the steel ring 18 contacts the upper surface of the baffle 11. The steel ring 18 is used to increase the overall strength of the internal body and can be continuously connected to the building structure above the ground.

[0025] Furthermore, eight connectors 19 are fixedly connected to the outer surface of the steel bar ring 18. The eight connectors 19 are all located above the thin plate 16. The connectors 19 can be used to connect and extend the length of the steel bars, and also have the function of protecting the steel bars and reducing oxidation reactions.

[0026] Working principle: when in use, first use an external crane to put the whole device into the pit prepared in advance. During the descent, use the limit rod 12 to limit the movable plate 13, so that the movable plate 13 can freely adapt to the angle inside the baffle 11, so as to increase the friction between the storage tube 1 and the pit. At this time, if the location of the drill pit is sandy, water is likely to accumulate inside the pit. At this time, if the height of the accumulated water reaches the height of the filter tube 2, first use the dense holes on the surface of the threaded plug 8 and the sponge 4 to isolate larger stones and soil blocks, and then the accumulated water slowly penetrates into the interior of the filter tube 2. At this time, use the multi-layer filtration of the first-level filter cotton 5, the second-level filter cotton 6 and the third-level filter cotton 7 to ensure that sewage cannot enter the interior of the storage tube 1. The first-level filter cotton 5 is a filter cotton of fifty nanometers, the second-level filter cotton 6 is a filter cotton of thirty nanometers, and the third-level filter cotton 7 is a filter cotton of ten nanometers. This is pouring concrete into the pipe. First, the poured concrete can be gathered by using the thin plate 16 to ensure the overall integrity of the final pillar. Part of the concrete leaks out from the leakage hole 17 and fills the gap between the hole and the support rod 14, thereby achieving external caulking to adapt to the hole, increasing friction and load-bearing capacity. The internal body is cylindrical to ensure integrity and durability. Finally, after the pouring is completed, the connector 19 is installed on the outer surface of the steel bar to prevent the steel bar from oxidation and rusting, etc. Finally, six filter tubes 2 are used to allow the water that penetrates the bottom to continue to flow into the interior of the storage tube 1. During this period, the concrete will not be affected by excess external water, and can achieve the ideal strength while ensuring the stability of the pillar.
