Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, and in particular to an advanced consolidation grouting structure for the excavation of surge tanks. Background Technology

[0002] In water conservancy and hydropower engineering construction, surge tanks are a common and very important hydraulic structure. Due to limitations imposed by topography, geology, and the overall project layout, surge tanks are often located in Class IV or V surrounding rock geological areas, with some sections even situated within overburden layers. During excavation, deformation and collapse of the well walls frequently occur, posing significant challenges to the excavation process. To prevent deformation and collapse during excavation, current methods typically involve simultaneous excavation and application of anchor spraying and steel supports.

[0003] However, in the use of existing grouting structures, the connection between the two grouting pipes is not very firm, and they may break when grouting is carried out after being placed underground, which affects the construction progress and poses certain safety risks. Therefore, this application provides an advanced consolidation grouting structure for pressure regulating well excavation to meet the requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an advanced consolidation grouting structure for the excavation of pressure regulating wells, so as to solve the problem that the connection between the two grouting pipes is not very firm when the existing grouting structure is used, and may break when grouting is carried out after being placed underground.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An advanced consolidation grouting structure for excavating pressure regulating wells includes a fixed pipe, a fixing plate inserted into the lower surface of the fixed pipe, a connecting pipe sleeved on the upper surface of the fixed pipe, a connecting plate inserted into the lower surface of the connecting pipe, a connecting bolt threaded through one side of the connecting plate, a washer sleeved on the surface of the connecting bolt, and a fixing component inserted into the lower surface of the connecting pipe.

[0007] Optionally, the fixing assembly includes a fixing seat, a mating pad, a telescopic rod, a spring, and a fixing head. The mating pads are inserted into both sides of the fixing seat, and the telescopic rod is inserted into one side of the mating pad. The surface of the telescopic rod is provided with a spring, and a fixing head is sleeved on one end of the telescopic rod.

[0008] Optionally, the mating pad is made of rubber, and the spring is located between the mating pad and the fixing head.

[0009] Optionally, the surface of the fixing tube is provided with a plurality of fixing holes, and the fixing holes are spaced equally apart.

[0010] Optionally, the surface of the connecting pipe is provided with a plurality of mating holes, and the spacing between the mating holes is equal.

[0011] Optionally, the fixed tube is provided with eight fixing reinforcing ribs inside.

[0012] Optionally, the inside of the connecting pipe is provided with eight butt reinforcing ribs.

[0013] Optionally, the upper surface of the fixing tube is provided with multiple fixing rods, and threaded holes are provided on both sides of the fixing tube.

[0014] Optionally, the upper surface of the connecting pipe is provided with a plurality of connecting rods, and threaded holes are provided on both sides of the connecting pipe.

[0015] Optionally, the upper surface of the fixed tube is provided with multiple placement slots, and the upper surface of the connecting tube is provided with multiple placement slots.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above scheme, external piling equipment is used to drill holes of a predetermined depth into the ground at designated locations. After workers align the fixed pipe and the connecting pipe, they compress the telescopic rods and springs on both sides of the fixing seat, allowing the fixing head to enter the placement groove inside the fixed pipe. The springs then release the telescopic rods, connecting and fixing the fixed pipe and the connecting pipe. After workers insert the connecting plate into both sides of the fixed pipe, they secure the connecting plate and the fixed pipe again with connecting bolts. Adding reinforcing ribs to the inside of the fixed pipe and the connecting pipe increases their strength, achieving a convenient and quick connection that is more secure and reliable. The operation is simple and flexible, improving compressive and deformation resistance, thereby reducing the risk of loose connections in the grouting pipe and ensuring its stability on the ground. The occurrence of cracks reduces the service life of the grouting pipe. When the hole depth is too deep, multiple connecting pipes can be connected. The workers compress the telescopic rods and springs on both sides of the fixing seat, so that the fixing head enters the placement groove inside another connecting pipe. Then, the spring causes the telescopic rod to pop out, connecting and fixing the connecting pipe to the other connecting pipe. After the workers insert the docking plate into both sides of the other connecting pipe, the docking plate and the other connecting pipe are fixed again with the docking bolts. When the grouting pipe reaches the hole depth, it is placed into the hole, and the fixing plate on the lower surface of the fixing pipe is inserted into the ground. Grout is injected into the grouting pipe, and the grout flows out into the underground gaps through the fixing holes on the surface of the fixing pipe and the docking holes on the surfaces of the multiple connecting pipes, filling the underground gaps and improving the integrity and strength of the bedrock.

[0031] like Figures 1 to 4As shown, an embodiment of this utility model provides an advanced consolidation grouting structure for pressure regulating well excavation, including a fixed pipe 1, a fixing plate 2 inserted into the lower surface of the fixed pipe 1, a connecting pipe 3 sleeved on the upper surface of the fixed pipe 1, a plurality of connecting holes 9 with equal spacing on the surface of the connecting pipe 3, eight connecting reinforcing ribs 11 inside the connecting pipe 3, a plurality of connecting rods on the upper surface of the connecting pipe 3, threaded holes on both sides of the connecting pipe 3, a plurality of placement grooves on the upper surface of the connecting pipe 3, a connecting plate 4 inserted into the lower surface of the connecting pipe 3, a connecting bolt 5 threaded through one side of the connecting plate 4, a washer 6 sleeved on the surface of the connecting bolt 5, and a fixing component 7 inserted into the lower surface of the connecting pipe 3. The device includes a fixing base 701, a mating pad 702, a telescopic rod 703, a spring 704, and a fixing head 705. The mating pad 702 is inserted into both sides of the fixing base 701. The mating pad 702 is made of rubber. The telescopic rod 703 is inserted into one side of the mating pad 702. The surface of the telescopic rod 703 is provided with a spring 704, which is located between the mating pad 702 and the fixing head 705. The fixing head 705 is sleeved on one end of the telescopic rod 703. The surface of the fixing tube 1 has multiple fixing holes 8 with equal spacing between them. The interior of the fixing tube 1 is provided with eight fixing reinforcing ribs 10. The upper surface of the fixing tube 1 is provided with multiple fixing rods. The two sides of the fixing tube 1 are provided with threaded holes. The upper surface of the fixing tube 1 is provided with multiple placement grooves.

[0032] By using external piling equipment to drill holes of a predetermined depth at designated locations, and aligning the positions of the fixed pipe 1 and the connecting pipe 3, the workers compress the telescopic rods 703 and springs 704 on both sides of the fixed seat 701, causing the fixing head 705 to enter the placement groove inside the fixed pipe 1. Then, the springs 704, carrying the telescopic rods 703, pop out, connecting and fixing the fixed pipe 1 and the connecting pipe 3. After inserting the connecting plate 4 into both sides of the fixed pipe 1, the connecting bolts 5 are used to further secure the connecting plate 4 and the fixed pipe 1. By adding reinforcing ribs 10 and 11 inside the fixed pipe 1 and the connecting pipe 3, the strength of the fixed pipe 1 and the connecting pipe 3 is increased, achieving a convenient and quick connection between the fixed pipe 1 and the connecting pipe 3. The connection is more secure and reliable, the operation is simple and flexible, and the compressive and deformation resistance is improved, thereby reducing the risk of loose connections in the grouting pipe and ensuring its stability underground. The current rupture reduces the service life of the grouting pipe. When the hole depth is too deep, multiple connecting pipes 3 can be connected. The workers compress the telescopic rods 703 and springs 704 on both sides of the fixing seat 701, so that the fixing head 705 enters the placement groove inside another connecting pipe 3. Then, the spring 704 pops out with the telescopic rods 703, so that the connecting pipe 3 and the other connecting pipe 3 are connected and fixed. After the workers insert the connecting plate 4 into both sides of the other connecting pipe 3, the connecting bolts 5 are used to fix the connecting plate 4 and the other connecting pipe 3 again. When the grouting pipe reaches the hole depth, the grouting pipe is put into the hole, so that the fixing plate 2 on the lower surface of the fixing pipe 1 is inserted into the ground. Grout is injected into the grouting pipe, and the grout flows out into the underground gaps through the fixing holes 8 on the surface of the fixing pipe 1 and the connecting holes 9 on the surfaces of the multiple connecting pipes 3, filling the underground gaps and improving the integrity and strength of the bedrock.

[0033] The working principle of the technical solution provided by this utility model is as follows: A hole of predetermined depth is drilled into the ground at a designated location using external piling equipment. After the workers align the positions of the fixed pipe 1 and the connecting pipe 3, they compress the telescopic rods 703 and springs 704 on both sides of the fixed seat 701, causing the fixing head 705 to enter the placement groove inside the fixed pipe 1. Then, the springs 704, carrying the telescopic rods 703, spring out, connecting and fixing the fixed pipe 1 and the connecting pipe 3. After the workers insert the connecting plate 4 into both sides of the fixed pipe 1, they use connecting bolts 5 to further secure the connecting plate 4 and the fixed pipe 1. The strength of the fixed pipe 1 and the connecting pipe 3 is increased by adding fixing reinforcing ribs 10 and connecting reinforcing ribs 11 inside the fixed pipe 1 and the connecting pipe 3. When the hole depth is too deep, multiple connecting pipes can be connected. 3. For connection and use, the operator compresses the telescopic rods 703 and springs 704 on both sides of the fixing seat 701, so that the fixing head 705 enters the placement groove inside the other connecting pipe 3. Then, the spring 704 and the telescopic rods 703 pop out, connecting and fixing the connecting pipe 3 and the other connecting pipe 3. The operator inserts the docking plate 4 into both sides of the other connecting pipe 3, and then fixes the docking plate 4 and the other connecting pipe 3 again with the docking bolts 5. When the grouting pipe reaches the hole depth, the grouting pipe is put into the hole, so that the fixing plate 2 on the lower surface of the fixing pipe 1 is inserted into the ground. Grout is injected into the grouting pipe, and the grout flows out into the underground gaps through the fixing holes 8 on the surface of the fixing pipe 1 and the docking holes 9 on the surfaces of the multiple connecting pipes 3, filling the underground gaps to improve the integrity and strength of the bedrock.
