Abstract
Description
Technical Field
[0001] This invention relates to the field of power engineering technology, specifically to a grouting and reinforcement device for the entrance and exit of a directional drilling traction pipe in power engineering. Background Technology
[0002] A traction pipe is a type of pipeline that can cross railways and highways. It is typically installed under the roadbed with a cement sleeve or steel sleeve, and the traction pipe is pulled through the sleeve to ensure the safety of the pipeline and the railway or highway. It is particularly suitable for municipal water supply and drainage, power, communication, gas pipeline and other projects, and is especially suitable for crossing rivers, railways and densely built-up areas.
[0003] During the construction of directional drilling traction pipe, it is necessary to excavate a trench in the ground. After breaking the hole, the soil at the hole opening is often prone to collapse due to the loose soil. Therefore, it is necessary to reinforce the entrance and exit of the directional drill.
[0004] The current reinforcement method is reinforced concrete grouting reinforcement. Before grouting, the steel bars need to be bent and shaped to ensure a stable pouring effect. Then the steel bars need to be driven into the ground. A lot of time is also needed before and after construction to build and dismantle the steel bars and formwork before pouring. The construction process is quite complicated and affects work efficiency. Summary of the Invention
[0005] The purpose of this invention is to provide a grouting and reinforcement device for the entrance and exit of directional drilling traction pipe construction in power engineering in order to solve the above-mentioned problems, as detailed below.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] This invention provides a grouting and reinforcement device for the entrance and exit of a directional drilling traction pipe in power engineering. It includes two semicircular plates, both ends of which can be joined to form a ring via bolts. Several ear plates are fixedly connected to the circumference of the two semicircular plates. A soil-breaking cone rod is rotatably connected to the middle ear plate of each semicircular plate, and both soil-breaking cone rods have spiral patterns. Reinforcing cones can be detachably installed on the remaining ear plates. Four evenly distributed pressure plates are provided inside the two semicircular plates, and the pressure plates can move radially along the semicircular plates. L-shaped templates are provided on both sides of the ring formed by the combination of the two semicircular plates, and bolts are provided on the side walls of the semicircular plates to fix the position of the L-shaped templates.
[0008] Preferably, the bolted connector includes sleeves fixed to the ends of two semicircular plates, with the same bolt inserted into both sleeves, and a nut threaded onto the end of the bolt.
[0009] Preferably, one of the semicircular plates has protruding rods fixedly connected to both ends, and the other semicircular plate has recessed holes at both ends that are adapted to the insertion of the protruding rods.
[0010] Preferably, the soil-breaking cone has a hollow groove inside, and a number of through holes communicating with the outside are opened on the side of the hollow groove near the tip. A top rod is inserted into each of the through holes, and a plug rod for driving the top rods to extend out of the soil-breaking cone is inserted into the hollow groove.
[0011] Preferably, the push rods are staggered in pairs, the ends of the push rods are designed with pointed tips, and the ends of the push rods are provided with anti-detachment rings to prevent them from falling out of the through holes.
[0012] Preferably, the ear plate is fixedly connected to an insertion sleeve for inserting a reinforcing cone. The tail end of the reinforcing cone is threadedly connected to the insertion sleeve through an opening thread. Each insertion sleeve is designed to be inclined and face the axis of the annulus formed by the two semicircular plates.
[0013] Preferably, a threaded rod is rotatably connected to the semicircular plate. The threaded rod is distributed along the axis of the annulus formed by the two semicircular plates. A threaded sleeve is threadedly connected to the threaded rod. A hinge seat is fixedly connected to both the threaded sleeve and the inner wall of the semicircular plate. A linkage arm is rotatably connected to each of the two hinge seats. The other end of each linkage arm is rotatably connected to the middle of the pressure plate.
[0014] Preferably, the bolt fastener includes two threaded rods fixedly connected to the side wall of the semi-circular plate. The L-shaped template has two insertion holes for inserting the threaded rods. Two nuts are threadedly connected to the threaded rods, and the two nuts are located on the inner and outer sides of the L-shaped template, respectively.
[0015] Preferably, a pipe-through groove is provided in the middle of the splicing end of the two L-shaped templates, and a pipe diameter marking line is provided on both pipe-through grooves.
[0016] The beneficial effects are:
[0017] By pushing the semicircular plate to insert the tips of two soil-breaking cones into the trench wall, and simultaneously rotating the two soil-breaking cones for initial reinforcement, the semicircular plates are moved into the trench wall. Then, insert rods are inserted into the hollow trench, causing several top rods to extend for secondary reinforcement. Subsequently, reinforcing cones are inserted into the insert sleeves in the remaining ear plates for tertiary reinforcement. Then, two L-shaped templates are installed on both sides of the ring formed by the two semicircular plates. Finally, grout is injected into the gap between the two L-shaped templates and the trench wall to complete the reinforcement. The operation is quick and convenient, with good fixing effect. The templates are easy to disassemble, improving practicality. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0030] See Figures 1-8 As shown, the present invention provides a grouting reinforcement device for the entrance and exit of directional drilling traction pipe construction in power engineering, including two semicircular plates 1. The two ends of the two semicircular plates 1 can be spliced into a ring shape by bolts. Several ear plates 2 are fixedly connected to the circumference of the two semicircular plates 1. A soil-breaking cone rod 3 is rotatably connected to the middle ear plate 2 of the two semicircular plates 1, and both soil-breaking cone rods 3 are provided with spiral patterns. Reinforcing cones 4 can be detachably installed on the remaining ear plates 2. Four evenly distributed pressure plates 5 are provided inside the two semicircular plates 1, and the pressure plates 5 can move radially along the semicircular plates 1. L-shaped templates 6 are provided on both sides of the ring formed by the combination of the two semicircular plates 1, and bolt fasteners 7 are provided on the side walls of the semicircular plates 1 to fix the position of the L-shaped templates 6.
[0031] Reference Figure 5 As shown, the bolted connector includes inserts 101 fixed to the ends of two semicircular plates 1. The same bolt 102 is inserted into the two inserts 101. The end of the bolt 102 is threaded with a nut 103. Both ends of one semicircular plate 1 are fixedly connected with protruding rods 104. Both ends of the other semicircular plate 1 are provided with recessed holes 105 that are adapted to the insertion of the protruding rods 104. First, the protruding rods 104 are inserted into the recessed holes 105 to complete the initial connection of the two semicircular plates 1. Then, the bolt 102 is inserted into the two inserts 101 at the same time. Finally, the nut 103 is rotated at the end of the bolt 102 to complete the splicing and fixing of the two semicircular plates 1.
[0032] Reference Figure 3 As shown, the soil-breaking cone 3 has a hollow groove 301 inside. Near the tip of the hollow groove 301, there are several through holes 303 communicating with the outside. A top rod 304 is inserted into each through hole 303. Insert rods 302 are inserted into the hollow groove 301 to drive the top rods 304 out of the soil-breaking cone 3. The top rods 304 are distributed in pairs and staggered. The ends of the insert rods 302 are designed with pointed tips, and the ends of the top rods 304 are provided with anti-detachment rings to prevent them from falling out of the through holes 303. By rotating the soil-breaking cone 3, it can be rotated and inserted into the vertical wall of the soil trench. Then, insert rods 302 are inserted into the hollow groove 301 (which can be done by hammering with tools such as hammers). The tips of the insert rods 302 abut against the tail ends of the top rods 304 in sequence, supporting the top rods 304 to extend out of the through holes 303 in sequence and penetrate the soil layer, which can further improve the firmness of the soil-breaking cone 3 in the soil layer.
[0033] Reference Figure 5As shown, an insertion sleeve 401 for inserting a reinforcing cone 4 is fixedly connected to the ear plate 2. The tail end of the reinforcing cone 4 is threaded to the insertion sleeve 401 through a thread 402. Each insertion sleeve 401 is designed to be inclined and faces the axis of the ring formed by the two semicircular plates 1. The reinforcing cone 4 can be inserted into the other insertion sleeves 401. Since the insertion sleeve 401 is designed to be inclined, the reinforcing cone 4 is inserted at an incline when it penetrates the soil wall, which can improve the reinforcement effect. After the tail end of the reinforcing cone 4 approaches the insertion sleeve 401, the reinforcing cone 4 can be rotated and fixed in the insertion sleeve 401 through the thread 402.
[0034] Reference Figure 4 As shown, a threaded rod 501 is rotatably connected to the semicircular plate 1. The threaded rod 501 is distributed along the axis of the ring formed by the two semicircular plates 1. A threaded sleeve 503 is threadedly connected to the threaded rod 501. A hinge seat 502 is fixedly connected to both the threaded sleeve 503 and the inner wall of the semicircular plate 1. A linkage arm 504 is rotatably connected to each of the two hinge seats 502. The other end of each linkage arm 504 is rotatably connected to the middle of the pressure pipe plate 5. By rotating the threaded rod 501, the threaded sleeve 503 can be moved to its outer side. The two hinge seats 502 move closer to each other, supporting the other end of the two linkage arms 504 away from the threaded rod 501. At the same time, the pressure pipe plate 5 is driven to abut against the surface of the traction pipe, and the position of the two semicircular plates 1 on the outside of the traction pipe is initially positioned. After the soil-breaking cone 3 and the reinforcing cone 4 are fully inserted into the soil, the threaded rod 501 can be rotated again to drive the pressure pipe plate 5 to be further clamped and fixed on the outside of the traction pipe.
[0035] Reference Figure 1-2 As shown, the bolt fastener 7 includes two threaded rods 701 fixedly connected to the side wall of the semi-circular plate 1. The L-shaped template 6 has two insertion holes 703 for inserting into the threaded rods 701. Two nuts 702 are threadedly connected to the threaded rods 701, and the two nuts 702 are located on the inner and outer sides of the L-shaped template 6 respectively. First, one nut 702 is rotated on the threaded rod 701 so that it is located on the inner side. Then, the L-shaped template 6 is fitted onto the threaded rod 701 through the insertion hole 703. Then, the other nut 702 is also rotated on the threaded rod 701. Through the clamping and cooperation of the two nuts 702, the L-shaped template 6 can be positioned and fixed.
[0036] Reference Figure 6 As shown, the two L-shaped templates 6 are provided with pipe grooves 9 in the middle of their splicing ends, and both pipe grooves 9 are provided with pipe diameter marking lines 8. The pipe grooves 9 can be cut to the size of different types of traction pipes through the pipe diameter marking lines 8, so that the pipe grooves 9 fit tightly with the side wall of the traction pipe, which is convenient for subsequent grouting.
[0037] In use, two semicircular plates 1 are joined together to form a ring using bolts and fitted onto the outside of the traction pipe. Then, by rotating the threaded rod 501, the threaded sleeve 503 is moved toward the semicircular plate 1, thereby moving the pressure plate 5 toward the surface of the pipe to abut. Then, the semicircular plate 1 is pushed to drive the tips of the two soil-breaking cone rods 3 into the vertical wall of the trench. At the same time, the two soil-breaking cone rods 3 are rotated for initial reinforcement, causing them to move the two semicircular plates 1 into the vertical wall of the trench. Then, the insertion rod 302 is inserted into the hollow trench 301, causing several top rods 304 to extend for secondary reinforcement. Then, the reinforcing cone 4 is inserted into the insertion sleeve 401 in the remaining ear plates 2 for tertiary reinforcement. Then, two L-shaped templates 6 are placed on both sides of the ring formed by the two semicircular plates 1 and fitted onto the threaded rod 701. The position of the L-shaped templates 6 can be adjusted and fixed by rotating the nut 702. Finally, grout is injected into the gap between the two L-shaped templates 6 and the vertical wall of the trench to complete the reinforcement.
[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
