Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] An embodiment of an efficient deep inclined shaft grouting grounding device convenient for installation according to the present invention is as Figures 1 to 10 shown.

[0031] An efficient deep inclined shaft grouting grounding device convenient for installation is installed in a grounding hole opened on a deep inclined shaft 600. The grounding hole is inclined. The device includes a grounding member 100, a grouting cylinder 200, and a support frame 300. The grouting cylinder 200 is arranged in the vertical direction, and the arrangement direction of the grouting cylinder 200 is called the first direction. The grounding member 100 is installed in the grouting cylinder 200 and is coaxial with the grouting cylinder 200. The support frame 300 is sleeved outside the grouting cylinder 200, and the support frame 300 can expand or contract along the second direction, and the second direction is the radial direction of the grouting cylinder 200. In the initial state, there is a gap between the support frame 300 and the soil where the grounding hole is located.

[0032] The grouting cylinder 200 has an open state and a closed state. When in the closed state, the flow of the slurry in the grouting cylinder 200 to the support frame 300 is restricted; when in the open state, the slurry in the grouting cylinder 200 is allowed to flow to the support frame 300. In the initial state, the grouting cylinder 200 is in the closed state, and when the grouting cylinder 200 is in the open state, the support frame 300 can expand along the second direction and be inserted into the soil where the grounding hole is located.

[0033] In this embodiment, by setting the grounding member 100, the grouting cylinder 200 and the support frame 300 to cooperate, during use, first a grounding hole is opened on the deep inclined shaft 600, and then the grounding member 100, the grouting cylinder 200 and the support frame 300 are integrally extended into the grounding hole. At this time, the grouting cylinder 200 is in the closed state, and the support frame 300 does not contact the soil where the grounding hole is located. Then grout is injected into the grouting cylinder 200, and the slurry will fill the grouting cylinder 200. After the slurry fills the grouting cylinder 200, the grouting pressure is increased to make the grouting cylinder 200 in the open state, and the slurry will flow from the grouting cylinder 200 to the support frame 300, and continue to fill the gap between the grouting cylinder 200 and the grounding hole. Only one grouting operation is required, which greatly improves the working efficiency. And at this time, the support frame 300 will expand along the second direction and be inserted into the soil where the grounding hole is located, using the soil to support the support frame 300, and through the support frame 300 to support and position the grouting cylinder 200 and the grounding member 100, weakening the influence of the grouting pressure on the support frame 300, the grouting cylinder 200 and the grounding member 100, preventing the support frame 300, the grouting cylinder 200 and the grounding member 100 from being pushed out of the grounding hole by the grouting pressure, and when the slurry fills the internal space of the grounding hole, the slurry will gradually diffuse into the surrounding soil, filling the cracks in the surrounding soil to form a root system and improving the grounding ability.

[0034] In a further embodiment, a plurality of slurry outlets 210 are opened on the grouting cylinder 200. A baffle 220 is provided on each slurry outlet 210. The baffle 220 is an arc-shaped plate and is coaxially arranged with the grouting cylinder 200. The baffle 220 is rotatably mounted on the slurry outlet 210 of the corresponding grouting cylinder 200 around the first direction. In the initial state, the baffle 220 blocks the corresponding slurry outlet 210, and at this time the grouting cylinder 200 is in the closed state.

[0035] In the initial state, the baffle 220 blocks the corresponding slurry outlet 210. After the slurry fills the grouting cylinder 200, the grouting pressure is increased, so that the baffle 220 can rotate around the first direction to open the slurry outlet 210, and at this time the grouting cylinder 200 is in the open state.

[0036] In a further embodiment, a plurality of slurry outlets 210 that are alternately distributed in sequence along the first direction are respectively referred to as a first outlet and a second outlet; both ends of the baffle 220 in the circumferential direction of the grouting cylinder 200 are respectively referred to as a first end and a second end. At the first outlet, the first end of the baffle 220 is rotatably mounted on the grouting cylinder 200 around the first direction and blocks the first outlet corresponding to the baffle 220. At the second outlet, the second end of the baffle 220 is rotatably mounted on the grouting cylinder 200 around the first direction and blocks the second outlet corresponding to the baffle 220.

[0037] By changing the installation directions of the baffle 220 at the first outlet and the baffle 220 at the second outlet, the opening directions of the baffle 220 at the first outlet and the baffle 220 at the second outlet are made opposite to prevent the baffle 220 from pushing the support frame 300 to rotate and improve the stability of the support frame 300.

[0038] In a further embodiment, the support frame 300 includes a plurality of support rings 310. The plurality of support rings 310 are sequentially arranged in the first direction and are connected by a plurality of support rods 320. The support rods 320 are arranged along the first direction. The support ring 310 is a multi-pointed star structure and has elasticity, enabling the support frame 300 to expand or contract along the second direction. The end of the support ring 310 close to the grouting cylinder 200 along the second direction is referred to as the inner end, and the end of the support ring 310 far from the grouting cylinder 200 along the second direction is referred to as the outer end, and the plurality of support rods 320 are all located at the inner end of the support ring 310. The outer end of the support ring 310 is a blade-like structure, which is convenient for inserting into the soil.

[0039] Specifically, the support ring 310 is a six-pointed star structure. Each slurry outlet channel includes six slurry outlets 210. The support rods 320 are arranged in one-to-one correspondence with the slurry outlets 210. In the initial state, each support rod 320 abuts against the baffle 220 on the slurry outlet 210 corresponding to it.

[0040] Furthermore, the plurality of support rings 310 arranged in sequence in the first direction are also connected by a plurality of fixing rods 330. The fixing rods 330 are arranged along the first direction.

[0041] By providing the fixing rods 330, the stability of the connection between the plurality of support rings 310 is further improved.

[0042] Alternatively, the support ring 310 can also be a four-pointed star or a five-pointed star structure. The inner ends of the support rings 310 are arranged in one-to-one correspondence with the slurry outlets 210. That is, when the support ring 310 is a four-pointed star structure, each slurry outlet channel includes four slurry outlets 210. When the support ring 310 is a five-pointed star structure, each slurry outlet channel includes five slurry outlets 210.

[0043] Further, the lower end of the grouting cylinder 200 is penetrated and fixedly connected with a receiving plate 260. The receiving plate 260 is a circular plate, and the diameter of the receiving plate 260 is larger than that of the grouting cylinder 200. The lower end of the support frame 300 can abut against the receiving plate 260.

[0044] The support frame 300 is supported by arranging the receiving plate 260.

[0045] When the baffle 220 rotates in the first direction to open the slurry outlet 210, the baffle 220 will synchronously push the corresponding support rod 320. The support rod 320 will move in the second direction. The support rod 320 is used to cause the support frame 300 to expand in the second direction, so that the overall shape of the support frame 300 deforms, and the outer end of the support frame 300 is further inserted into the soil where the grounding hole is located. See Figure 9 and Figure 10 as shown.

[0046] In a further embodiment, a high-efficiency grouting grounding device for a deep inclined shaft that is easy to install further includes a connecting cylinder 400. The connecting cylinder 400 is arranged along the first direction. The connecting cylinder 400 is installed at the upper end of the grouting cylinder 200 and is communicated with the grouting cylinder 200. A feed port 410 is provided on the connecting cylinder 400.

[0047] During use, an external high-pressure pump is connected to the feed port 410 through a grouting pipe. The high-pressure pump is used to make the damping material slurry enter the feed port 410 through the grouting pipe. The high-pressure pump and the grouting pipe are not shown in the attached drawings of the specification.

[0048] In a further embodiment, a limiting ring 230 is coaxially arranged in the grouting cylinder 200. The limiting ring 230 is connected to the grouting cylinder 200 through a plurality of connecting rods 240. Specifically, three connecting rods 240 are provided, and the three connecting rods 240 are evenly distributed in the circumferential direction of the limiting ring 230.

[0049] A lead wire cylinder 420 is coaxially and fixedly arranged in the connecting cylinder 400. The diameter of the lead wire cylinder 420 is smaller than that of the connecting cylinder 400. The upper and lower ends of the lead wire cylinder 420 are penetrated. The grounding member 100 includes a grounding wire 110 and a grounding rod 120. The grounding wire 110 and the grounding rod 120 are arranged in sequence and fixedly connected in the first direction. The grounding wire 110 and the grounding rod 120 are of an integrally formed structure. The grounding wire 110 is inserted into the lead wire cylinder 420, and the grounding rod 120 is inserted into the limiting ring 230.

[0050] Further, a plurality of limiting rings 230 are provided. The plurality of limiting rings 230 are sequentially arranged in the grouting cylinder 200 along the first direction. The plurality of limiting rings 230 are connected by limiting rods 250. The limiting rods 250 are arranged along the first direction.

[0051] By setting the limit ring 230, when in use, the grounding part 100 is inserted into the limit ring 230 to limit the grounding part 100 and improve the stability of the grounding part 100.

[0052] Specifically, a snap ring 430 is provided at the lower end of the connecting cylinder 400. The snap ring 430 is provided on the inner peripheral wall surface of the connecting cylinder 400. A boss 270 is provided at the upper end of the grouting cylinder 200. The boss 270 is provided on the outer peripheral wall surface of the grouting cylinder 200. The snap ring 430 is snap-connected to the boss 270.

[0053] Furthermore, a slurry blocking ring 500 is further included in the efficient deep inclined shaft grouting grounding device which is easy to install. The slurry blocking ring 500 is pressed on the ground where the grounding hole is located and is sleeved with the connecting cylinder 400. A pressing plate 440 is provided on the outer peripheral wall surface of the connecting cylinder 400. The pressing plate 440 is a circular plate. The radius of the inner circle of the slurry blocking ring 500 is smaller than the radius of the pressing plate 440. The upper end surface of the slurry blocking ring 500 can abut against the lower end surface of the pressing plate 440. When the grounding hole is inclined, the pressing plate 440 is inclined relative to the connecting cylinder 400 so that the pressing plate 440 can abut against the slurry blocking ring 500.

[0054] By setting the slurry blocking ring 500, the overflow of the slurry from the grounding hole can be blocked.

[0055] Specifically, the connecting cylinder 400 includes two cylinder bodies 401. The cross sections of the two cylinder bodies 401 are both semi-circular. The two cylinder bodies 401 are connected by a plurality of bolts 402.

[0056] During installation, first, the slurry blocking ring 500 is sleeved on one of the cylinder bodies 401, and then the boss 270 of the grouting cylinder 200 is snap-connected to the snap ring 430 of the connecting cylinder 400. Then, the grounding rod 120 is inserted into the limit ring 230, and the grounding wire 110 is inserted into the lead cylinder 420 so that the upper end of the grounding rod 120 abuts against the lower end of the lead cylinder 420 to limit the grounding rod 120. Then, the two cylinder bodies 401 are connected by bolts 402, and the support frame 300 is sleeved on the grouting cylinder 200. The overall structure is simple and the installation is convenient.

[0057] Combined with the above embodiments, the specific working process is as follows:

[0058] During installation, first, the slurry blocking ring 500 is sleeved on one of the cylinder bodies 401, and then the boss 270 of the grouting cylinder 200 is snap-connected to the snap ring 430 of the connecting cylinder 400. Then, the grounding rod 120 is inserted into the limit ring 230, and the grounding wire 110 is inserted into the lead cylinder 420 so that the upper end of the grounding rod 120 abuts against the lower end of the lead cylinder 420 to limit the grounding rod 120. Then, the two cylinder bodies 401 are connected by bolts 402, and the support frame 300 is sleeved on the grouting cylinder 200 to complete the installation.

[0059] After installation, during use, first drill a grounding hole in the deep inclined shaft 600, and then insert the grounding part 100, grouting cylinder 200 and support frame 300 as a whole into the grounding hole, and press the slurry blocking ring 500 on the ground where the grounding hole is located. Refer to Figure 7 and Figure 8 as shown.

[0060] At this time, the grouting cylinder 200 is in a closed state, and the support frame 300 does not contact the soil where the grounding hole is located. Then, grout is injected into the grouting cylinder 200, and the slurry will fill the grouting cylinder 200. After the slurry fills the grouting cylinder 200, increase the grouting pressure so that the baffle 220 can rotate around the first direction to open the slurry outlet 210. When the baffle 220 rotates around the first direction to open the slurry outlet 210, the baffle 220 will synchronously push the corresponding support rod 320, and the support rod 320 will move along the second direction. Use the support rod 320 to promote the expansion of the support frame 300 along the second direction, causing the overall deformation of the support frame 300, and further inserting the outer end of the support frame 300 into the soil where the grounding hole is located. Refer to Figure 9 and Figure 10 as shown.

[0061] After the slurry outlet 210 is opened, the slurry will flow from the grouting cylinder 200 to the support frame 300, and continue to fill the gap between the grouting cylinder 200 and the grounding hole. Only one grouting operation is required, which greatly improves the work efficiency. And after the outer end of the support frame 300 is inserted into the soil where the grounding hole is located, use the soil to support the support frame 300, and support and position the grouting cylinder 200 and the grounding part 100 through the support frame 300, weakening the influence of the grouting pressure on the support frame 300, grouting cylinder 200 and grounding part 100, and preventing the support frame 300, grouting cylinder 200 and grounding part 100 from being pushed out of the grounding hole by the grouting pressure. And when the slurry fills the internal space of the grounding hole, the slurry will gradually diffuse into the surrounding soil, filling the cracks in the surrounding soil, forming a root system, and improving the grounding ability.

[0062] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
