Description
Technical Field
[0001] The present invention belongs to the technical field of tunnel construction and relates to a multi-adjustable guided drilling pipe shed device. Background Art
[0002] At present, in urban construction projects, due to the need to make full use of underground space, a large number of pre-reinforcement and pre-support measures have emerged, which play a crucial role in ensuring the safety of the tunnel construction process. The pipe shed advanced support method is a new technology with a relatively perfect construction process, high reliability, and good control effect on soil settlement in soft surrounding rocks, fractured rocks with many bedding planes, and poor geological sections.
[0003] In recent years, the pipe shed support technology has developed rapidly and has been gradually widely adopted in the construction of subway shield tunnels for supporting and reinforcing the strata. The pipe shed support technology has the advantages of a long advanced support distance and a large stiffness, and can better be applied to work surfaces that cannot be self-stabilized by drilling and water-bearing strata. The pipe shed and the tunnel structure jointly form a support system, which can effectively control the deformation of the surrounding rock.
[0004] The current prior art: A guided drilling pipe shed for a rectangular mined tunnel (application number CN202020696947.1, publication date 20200605): mainly solves the connection of the guiding bit for the drilling azimuth of the pipe shed, the pipe shed for the advanced support of the tunnel soil body, and the drilling end of the pipe shed; A pipe shed construction method that is conducive to settlement control and can be guided to dry-form holes (application number CN201910552786.0, publication date 20190924): mainly solves the problem that the pipe shed is jacked into the hole by rotation to minimize the settlement caused by drilling, and a wire guide is used for monitoring and timely deviation correction, which is conducive to the accuracy of the pipe shed drilling direction; A pipe shed construction guiding and deviation correction device for sandy cobble strata (application number CN202011367213.X, application date 20210209): mainly solves the problems that often occur in the construction of pipe sheds in sandy cobble strata, such as uncontrollable driving accuracy and large deviations.
[0005] Although the existing pipe shed support technology has the above application advantages, it also has certain defects, mainly including the following points:
[0006] First, during the pipe shed construction process, inaccurate angle positioning of the pipe shed will lead to interference between adjacent pipe sheds during on-site installation or damage to other pipeline facilities in the stratum. At the same time, when the soil is excavated, the pipe shed has not reached the preset position, which will affect its support effect. Especially in the sand and gravel strata, the construction of advanced pipe sheds is difficult, mainly because the pebbles have the characteristics of large particle size, high content, and poor self-stabilization ability. As a result, the construction in the sand and gravel strata often has problems such as uncontrollable setting accuracy and large deviation, which limits the use of super-long pipe shed support structures in sand and gravel strata. The deviation correction drill used in the existing pipe shed construction is not suitable for construction in sand and gravel strata.
[0007] Secondly, the pipe-roof support method is mainly to reinforce the tunnel face area, install a bracket on the tunnel face, set pipe-roof pipes on the bracket along the circumference of the tunnel face, and drive the pipe-roof pipes into the tunnel along the excavation direction of the tunnel; the mountain around the tunnel exerts a large pressure on the pipe-roof pipes, which can easily cause the pipe-roof pipes to be dislocated. Although the bracket plays a certain supporting and fixing role on the pipe-roof pipes, the bracket is connected to the outer end of the pipe-roof pipe, and the end of the pipe-roof pipe driven into the tunnel is prone to tilt toward one side of the tunnel along the radial direction of the tunnel. The dislocation of the pipe-roof pipe causes the pipe-roof to deform, affecting the safety of tunnel excavation.
[0008] Then, the commonly used pipe shed construction method is the "wired guided one-time pipe shed construction method". This method uses the pipe shed as the drill rod, uses mud wall protection to form holes, and annular grouting inside and outside the pipe. Because the hole is larger than the diameter of the pipe shed, it is difficult to achieve full grouting, which can easily cause road subsidence. In addition, the construction requires mud, which is difficult to handle and easily causes environmental pollution.
[0009] Finally, due to the different sizes of pipe racks currently available, each time the pipe rack is constructed, it is necessary to replace the pipe rack connecting device with a corresponding size, which is costly, cumbersome to install, and not very firm. Summary of the invention
[0010] In order to achieve the above-mentioned purpose, the present invention provides a multi-adjustable guided drilling pipe-roof device, which solves the problems of excessive settlement easily caused by existing pipe-roof construction technology, difficulty in monitoring the up and down deviation of the drill bit, limited drill rod length, and cumbersome replacement of drill rods of different sizes.

Specific embodiments
[0032] 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.
[0033] As Figures 1 - 7 shown, the present invention provides a multi-adjustable guiding drilling pipe shed device, including a guiding drill bit 1, a pipe shed connecting pipe main body, a pipe shed internal main body, a pipe shed external main body, and an external device;
[0034] The pipe shed external main body includes an X-shaped blade 6 and a knob-type transmission joint 7;
[0035] The pipe shed internal main body includes a guide rod 4, a guiding detection eye 2, a laser emitter 23, and a laser receiving plate 24;
[0036] The external device includes a guiding display 9 and a magnetic switch 10;
[0037] The main body of the pipe shed connecting pipe includes a slide rail block 12, a drill pipe, an X-shaped slide bar 14, a vertical bar 13, and a rubber pad; the drill pipe includes a first connecting pipe 5 and a second connecting pipe 3.
[0038] Further, the guiding drill bit 1 is connected to the positioning hole at the upper end of the drill pipe of the main body of the pipe shed connecting pipe through a telescopic blocking contact 11; the guiding rod 4 of the main body inside the pipe shed is rotatably connected to the drill pipe of the main body of the pipe shed connecting pipe; the external main body of the pipe shed is fixed on the drill pipe; the external device is wirelessly connected to the laser receiving plate 24 of the main body inside the pipe shed and the magnetic seat 8 at the bottom of the guiding drill bit 1 respectively.
[0039] Further, the guiding drill bit 1 is composed of three conical steel sheets, which is a triangular tip cone shape, and the side surface is inclined with the bottom surface. The telescopic blocking contacts 11 are arranged in an equidistant circular arrangement around the magnetic seat 8 at the bottom of the guiding drill bit 1, and four telescopic blocking contacts 11 are arranged to achieve the purpose of reliably connecting the guiding drill bit 1 and the drill pipe. The magnetic seat 8 and the magnetic switch 10 of the external device are wirelessly connected. When the magnetic seat 8 is energized, it obtains magnetism, and when it is powered off, it loses magnetism. The magnetic switch 10 controls the on and off of the magnetic seat 8; the telescopic blocking contact 11 is elastically telescopic and is installed in the groove of the guiding drill bit 1. The telescopic blocking contact 11 includes a ferromagnetic metal layer, and when the magnetic seat 8 is energized, it can be attracted by the magnetism of the magnetic seat 8, so that the part of the telescopic blocking contact 11 that pops out of the groove retracts into the groove, and the drill bit and the drill pipe are separated; when the magnetic seat 8 is powered off, the telescopic blocking contact 11 pops out and is stuck into the positioning hole at the upper end of the main body of the pipe shed connecting pipe, so that the drill bit and the drill pipe are connected together.
[0040] Further, the main body inside the pipe shed includes a guiding detection eye 2. The lower end of the guiding detection eye 2 is rotatably connected to a laser emitter 23. The laser emitted by the laser emitter 23 under the influence of gravity always remains perpendicular to the lower direction; a laser receiving plate 24 is fixedly installed inside the drill pipe directly below the laser emitter 23. When the drilling angle deflects, the position where the laser emitted by the laser emitter 23 is incident on the laser receiving plate 24 will also change. Since the positions where the laser is incident on the laser receiving plate 24 are different due to different deflection angles, it is possible to sense at any time whether the drilling direction of the guiding drill bit 1 deviates, so as to correct the deviation in time. The guiding rod 4 is fixedly connected to the tail of the guiding detection eye 2. The laser receiving plate 24 and the guiding display 9 of the external device are wirelessly connected. The position of the laser on the laser receiving plate 24 is displayed on the guiding display 9 to observe the drilling direction of the guiding drill bit 1 at any time.
[0041] Furthermore, a slider 26 is fixedly installed outside the first connecting pipe 5, and a slide rail is fixedly installed inside the second connecting pipe 3. The drill pipe is mainly connected in a segmented and staggered manner, that is, a first connecting pipe 5 is arranged between two second connecting pipes 3, and the slider 26 is slidably installed in the slide rail of the second connecting pipe 3. A positioning hole corresponding to the size and position of the telescopic blocking contact 11 on the guiding drill bit 1 is arranged at the upper end of the second connecting pipe 3.
[0042] Furthermore, the pipe shed connecting pipe body further includes a circular cylinder 25. The circular cylinder 25 is sleeved on the guide rod 4, and the circular cylinder 25 is rotatably connected to the guide rod 4 through spherical beads. The spherical beads are rotatably installed between the annular groove on the rod body of the guide rod 4 and the annular groove of the circular ring. The circular cylinder 25 is fixedly connected to the first connecting pipe 5 through a vertical rod 13, and the circular cylinder 25 is slidably connected to the second connecting pipe 3 through four sliding rods 14. The four sliding rods 14 are in an X shape. A rubber pad is provided at the connection between the vertical rod 13 and the first connecting pipe 5, which can increase the friction at the connection between the vertical rod 13 and the first connecting pipe 5 while protecting the integrity of the structure, and can further prevent misalignment caused by vibration during drilling. The sliding rods 14 and the vertical rod mainly serve to prevent the drill pipe from being bent under pressure. One end of the sliding rod 14 is fixedly connected to the circular cylinder 25, and the other end is fixedly connected to a slide rail block 12 slidably installed in the slide rail of the second connecting pipe 3. The length of the guide rod 4 is greater than the length of the drill pipe. By stretching the guide rod 4, the overall sliding of the four sliding rods 14 and the sliding of the first connecting pipe 5 in the second connecting pipe 3 can be driven. Also, because the upper end of the first connecting pipe 5 sliding down to the end can drive the upper second connecting pipe 3 to move downward or the lower end of the first connecting pipe 5 sliding up to the end can drive the lower second connecting pipe 3 to move upward, that is, the sliding between the second connecting pipe 3 and the first connecting pipe 5 is driven. Therefore, the drill pipe can be telescopic.
[0043] Furthermore, the external main body of the pipe shed includes X-shaped blades 6 arranged in an X shape. The X-shaped blades 6 are fixed outside the second connecting pipe 3 of the drill pipe to facilitate drilling.
[0044] Furthermore, the external main body of the pipe shed includes a knob-type transmission joint 7, and the knob-type transmission joint 7 includes a first elastic ring 15; the first elastic ring 15 is fixedly connected to the lower end of the drill pipe; one end of a screw 17 is connected to the first elastic ring 15 through a screw base 21, and the other end of the screw 17 is rotatably connected to the inner side of a second elastic ring 22. The screws 17 are evenly distributed between the first elastic ring 15 and the second elastic ring 22; a first arc-shaped cushion block 16 is arranged between the screw base 21 and the first elastic ring 15, and a second arc-shaped cushion block 18 is arranged between the screw 17 and the second elastic ring 22 to play a role in adjusting the force; a rubber ring is installed inside the first elastic ring 15 to play a buffering role and prevent the vibration of the drill pipe from affecting the entire pipe shed device; the second elastic ring 22 and a third elastic ring 19 are rotatably connected through a spherical ball 20. By rotating the screw 17 to change the distance between the first elastic ring 15 and the second elastic ring 22, the size of the first elastic ring 15 can be changed (compressed or stretched), achieving that the size becomes larger when rotating clockwise and smaller when rotating counterclockwise; the screws 17 and the screw bases 21 are arranged at equal distances and equal angles along the circumference of the first elastic ring 15, so that the drill pipe is subjected to the action of lateral restraint force and can be more firm and reliable; the advantage of the knob-type transmission joint 7 is that drill pipes of different sizes can be limited to achieve the purpose of facilitating the replacement of the drill pipe. While the drill pipe is driven to rotate by an electric device, the third elastic ring 19 remains stationary.
[0045] Furthermore, the number of the screw bases 21 and the screws 17 is four or six. The screws 17 are installed in the screw bases 21, and the threads of the screws 17 match the threads of the screw bases 21. The screws 17 can be screwed in and out of the screw bases 21 (so as to realize the adjustable overall length of the screws 17 and the screw bases 21), realize the adjustable distance from the top end of the screw 17 to the center of the first elastic ring 15. Through the adjustment of the extended lengths of the four or six screws 17 in this device, the screws 17 are in close contact with the inner wall of the second elastic ring 22, and the axial position of the placed drill pipe is fixed by fixing the first elastic ring 15.
[0046] Furthermore, an injection molding layer, an anti-rust layer and a warning layer are sequentially sprayed from the inside to the outside on the outer surfaces of the guide bit 1, the drill pipe and the X-shaped blade 6; the injection molding layer is a high-molecular wear-resistant material; the anti-rust layer includes an epoxy zinc-rich primer, a chlorinated rubber topcoat and an epoxy mica iron intermediate coat located between the epoxy zinc-rich primer and the chlorinated rubber topcoat; the warning layer is a yellow or black reflective warning tape or reflective color film or reflective paint, which can prevent rust.
[0047] In some embodiments, during installation, first, the second connection pipe 3 of the drill pipe is slidably connected to the first connection pipe 5. After the drill pipe connection is completed, the guiding drill bit 1 is then connected to the second connection pipe 3 of the drill pipe through the telescopic blocking contact 11. After the connection is completed, the sliding rod 14 and the vertical rod 13 are respectively fixedly connected to the circular ring cylinder 25. At this time, the guide rod 4 can be rotationally connected to the above-mentioned part together. The guide rod 4 is fixedly connected to the guiding detection eye 2, and then the above-mentioned part is installed into the drill pipe together. A magnetic switch 10 is arranged on the guiding display 9, and the magnetic switch 10 controls the presence or absence of magnetism of the magnetic seat 8 on the guiding drill bit 1.
[0048] In some embodiments, during installation, first, the guiding detection eye 2 is fixedly installed inside the guiding drill bit 1. The display screen on the display is used to display the drilling azimuth of the guiding drill bit 1. The part of the telescopic blocking contact 11 on both sides of the guiding drill bit 1 that protrudes from the groove is pressed into the groove on both sides of the drill bit. After being inserted into the drill pipe, the part of the telescopic blocking contact 11 that is pressed into the groove pops out when it encounters the positioning hole, so that the guiding drill bit 1 is fixed inside the drill pipe.
[0049] In some embodiments, when driving the drill pipe into the soil mass, when the guiding drill bit 1 deviates from the predetermined track in a certain direction in the soil mass due to some reason, the drilling direction is monitored through the guiding display 9. When it is observed on the guiding display 9 that the drill bit direction deviates, the direction can be manually adjusted. The deflection azimuth of the drilling is monitored through the wirelessly connected guiding display 9. After the drill pipe erection is completed, the magnetic switch 10 that controls the magnetic seat 8 is turned on, so that the part of the telescopic blocking contact 11 inside the guiding drill bit 1 that protrudes from the groove is attracted by the magnetic force, and thus contracts into the inside of the guiding drill bit 1. Then, the guiding drill bit 1 is pulled out of the drill pipe through the magnetic guide rod 4 for recycling and reuse.
[0050] The installation process of the present invention is as follows:
[0051] First, the guiding drill bit 1 is installed inside the top end of the second connection pipe 3, and the installation is carried out based on the principle of mutual attraction of the opposite-sex magnets of the telescopic blocking contact 11. The first connection pipe 5 is installed between the two second connection pipes 3, and the two are slid relative to each other through the slider 26 on the outside of the first connection pipe 5 and the slide rail on the inside of the second connection pipe 3 to complete the installation of the drill pipe. The length of the drill pipe can be adjusted by sliding to adapt to the initial support pipe shed length setting under different conditions.
[0052] A guide rod 4 is rotatably installed inside the drill pipe through the circular ring cylinder 25. The guiding detection eye 2 is installed at the top end of the guide rod 4 to observe the change of the drilling direction at any time during the drilling process and prevent the drilling from deviating from the preset direction.
[0053] A laser emitter 23 is rotatably installed below the guiding detection eye 2 of the guide rod 4, and a laser receiving plate 24 is fixedly arranged inside the drill pipe below the laser emitter 23. The laser receiving plate 24 is wirelessly connected to the guiding display 9. Whether the guiding drill bit 1 and the entire direction of pipe roof drilling deviate up and down can be displayed on the guiding display 9. If deviation occurs, timely correction is required: take out the entire pipe roof, adjust the drilling direction again, and then put it into the borehole.
[0054] An X-shaped blade 6 is fixedly installed on the second connecting pipe 3 outside the drill pipe to perform rotary cutting on the soil during drilling; an X-shaped sliding rod 14 and a vertical rod 13 are fixedly installed between the drill pipe and the guide rod 4 to play a role in adjusting the length of the guide rod and supporting the inside of the pipe roof, preventing the pipe roof from being bent under pressure in the soil mass with relatively high pressure, and affecting subsequent grouting and the stress performance of the pipe roof.
[0055] By rotating and adjusting the length between the screw 17 and the screw base 21 in the knob-type transmission joint 7, the first ring 15 is opened, the drill pipe is installed into the first ring 15, and then the screw 17 is rotated to clamp the drill pipe. The drill pipe is driven to rotate by an electric device to make the entire device drill forward.
[0056] Each embodiment in this specification is described in a related manner. For the same or similar parts between each embodiment, reference can be made to each other. The key point of each embodiment is to illustrate the differences from other embodiments.
[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
