Description

Technical Field

[0001] The present invention relates to the technical field of tunnel boring, and in particular to a tunnel integrated trolley based on the full-face drill and blast method and its construction method. Background Art

[0002] At present, tunnel construction has basically achieved mechanized construction, and the large machine matching construction has become the standard. The large machine matching is actually different processes corresponding to different operation machines. On the one hand, when the current process is operating, other machines have to wait in a suitable area, resulting in problems such as waiting for machine process connection and low construction efficiency; on the other hand, the more operation machines there are, the more complex the transfer and scheduling are, and it is inevitable to avoid each other. Adding avoidance chambers increases the construction cost, and at the same time, coexisting with operators in the same complex environment, the safety of personnel and machines is low; finally, different professional machines need to be equipped with professional operators, who require high professional levels and high wage levels, are less replaceable, and the labor cost is high.

[0003] Although there are also similar multi-functional integrated machine equipment for tunnel full-face drill and blast method construction on the market, such as a full-face construction process based on a tunnel excavation and support integrated trolley in ZL202110714087.9, its functions are relatively single, generally only including general functions such as drilling and installation of steel arch frames, and other operation function modules need to be realized through the mode of replacement. As is well known, due to the narrow space in the tunnel, the replacement is difficult and time-consuming, and the replacement requires the cooperation of professional personnel, which undoubtedly increases the construction difficulty of the integrated trolley; at the same time, it is also counterproductive in terms of saving time, improving efficiency, and reducing costs. Summary of the Invention

[0004] The technical problems to be solved by the present invention are: the connection waiting between each operation process, the waiting of machine operations, the large number of professional operators, and the complex scheduling of machines brought by the current large machine matching construction in tunnels; the situation where multi-machine transfer and scheduling on the construction site coexist with construction workers in the same complex environment, and the safety of construction workers and construction machines is limited; the large machine matching construction machines alternate between transfers back and forth, resulting in low efficiency.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a tunnel integrated trolley based on the full-face drill and blast method, including a gantry. Multi-functional legs connected by bolts are symmetrically arranged at the front, middle, and lower part of the gantry. A single-side double-track chassis for support and driving is bolted below the gantry. Rock drilling and grouting arm modules and a grouting mixing system and a water system supporting the rock drilling and grouting arm modules are installed on both sides inside the gantry. Charging and wet spraying arm modules and an air compression system, an admixture system, and a concrete pumping system supporting the charging and wet spraying arm modules are installed on both sides at the upper end of the gantry. An underbreak removal operation arm module is installed at the very front of the gantry.

[0006] On both sides of the gantry, the first-layer structure and the second-layer structure are symmetrically connected by bolts.

[0007] At the exact middle position of the top layer of the gantry, a steel arch installation system is installed for swinging and lifting the steel arch, transporting the steel arch axially, and vertically lifting and jacking the steel arch.

[0008] The steel arch installation system includes single-piece or multi-piece steel arches to be lifted, transported, and installed by jacking, a swinging device, a lifting power device, a transfer walking and lifting assembly, a receiving and installing disc structural member, a walking track, and an intermediate transposition row of columns.

[0009] The charging wet shotcreting boom module is movably installed above the first-layer structure, and the charging wet shotcreting boom module includes a sprocket chain drive component, a walking track, a support and roller component, a pitching swing oil cylinder, a multi-stage telescopic boom, a hanging basket balance oil cylinder, an artificial charging hanging basket, and a wet shotcreting assembly.

[0010] The rock drilling and grouting injection boom module includes a sprocket chain drive component, a walking track, a support and roller component, a pitching swing oil cylinder, a multi-stage telescopic boom, an axial swing oil cylinder, a radial swing oil cylinder, and a drilling, anchoring, and grouting integrated working device.

[0011] The overbreak removal operation boom module includes a sliding component, a slewing drive, a mounting seat, a main boom pitching oil cylinder, a main boom, a vibratory hammer, a vibratory hammer pitching oil cylinder, an auxiliary boom, and an auxiliary boom pitching oil cylinder.

[0012] When receiving materials, the power receiving and installing disc structural member is at the lowest position, which is 2 cm to 10 cm lower than the highest position to which the single-piece or multi-piece steel arches are lifted.

[0013] When the single-piece or multi-piece steel arches are separated from the swinging device and transported forward to the intermediate transposition row of columns, during the transportation process, the bottom of the single-piece or multi-piece steel arches is raised by 2 cm to 10 cm relative to the corresponding position of the intermediate transposition row of columns to prevent the steel arches from interfering and colliding with the intermediate transposition row of columns.

[0014] During transposition, the transfer walking and lifting assembly is lowered to drive the receiving and installing disc structural member to descend until the single-piece or multi-piece steel arches are 2 cm to 10 cm behind the upper surface of the receiving position of the receiving and installing disc structural member before they can move, to prevent the receiving and installing disc structural member from interfering and colliding with the steel arches.

[0015] When continuing to transport, the transfer walking and lifting assembly is lifted, the single-piece or multi-piece steel arches are separated from the intermediate transposition row of columns, and their bottom is raised by 2 cm to 10 cm relative to the corresponding position of the intermediate transposition row of columns before they can continue to move forward, to prevent the steel arches from interfering and colliding with the intermediate transposition row of columns.

[0016] A construction method for a tunnel integrated trolley based on the full-section drill and blast method. The equipment enters the site and walks to the working face by itself. After measuring and positioning the position, the rock drilling and grouting injection arm module extends out of the gantry to drill blast holes at the working face. After the operation is completed, the rock drilling and grouting injection arm module retracts into the gantry. At the same time, the charging and wet spraying arm module extends out of the gantry to carry out the charging operation at the working face. After the operation is completed, the charging and wet spraying arm module retracts into the gantry. At the same time, the whole machine retreats to a safe distance to wait for the blasting construction. Then, the dust is reduced and the smoke is exhausted for the dust generated by the blasting construction. The whole machine walks to the working face by itself. The under-excavation removal and risk elimination arm module carries out the under-excavation repair and surrounding rock risk elimination operations. Then, the loader and the dump truck carry out the mucking operation. The charging and wet spraying arm module extends out of the gantry for the initial spraying operation of the working face and the tunnel body. At the same time, the under-excavation removal and risk elimination arm module makes way in real time according to needs. Then, the charging and wet spraying arm module retracts into the gantry. At the same time, single or multiple steel arch frames are transported from the tunnel entrance to the lifting and swinging device of the steel arch frame installation system at the rear of the equipment, and the steel arch frame is lifted, transported, and repositioned. The equipment moves to the working face, and the equipment re-measures and positions. The steel arch frame installation system is lifted until the steel arch frame is closely attached to the tunnel or the tunnel body. A cushion block is placed at the bottom of the steel arch frame for bearing, and at the same time, the connecting bars of the steel arch frame are welded to the previous steel arch frame and the mesh is overlapped and welded. The steel arch frame installation system retreats to the rearmost part of the whole machine. At the same time, the equipment retreats to vacate the working space for the locking foot bolt operation of the rock drilling and grouting injection arm module. The rock drilling and grouting injection arm module carries out the locking foot bolt operation, welds the steel arch frame and the locking foot bolt, and the system bolt drills and grouts. The charging and wet spraying arm module extends out of the gantry for the secondary spraying operation of the tunnel body. The charging and wet spraying module retracts into the gantry to restore the transfer state. The single-cycle primary support operation is completed.

[0017] During the system bolt drilling and grouting operation, the grouting mixing system and the water system make slurry, and then pump it to the drill-anchor-grout integrated working device;

[0018] The air compression system supplies air, and the admixture system pumps the accelerator. Then, the mixer truck transports the concrete to the concrete pumping system at the rear of the whole machine, and pumps the concrete to the charging and wet spraying arm module, where the compressed air and the accelerator are mixed at the spray nozzle, so as to cooperate with the charging and wet spraying arm module to extend out of the gantry for the initial spraying operation of the working face and the tunnel body;

[0019] When the rock drilling and grouting injection arm module extends out of the gantry to drill blast holes at the working face, the rock drilling and grouting injection arm module is supplied by an external pressure water system.

[0020] The beneficial effects of the present invention are:

[0021] (1) The tunnel integrated trolley and its construction method based on the full-section drill and blast method of the present invention integrate the common functions of tunnel construction such as rock drilling and hole making, charging, under-excavation repair and risk elimination, wet spraying, steel arch frame installation, bolt, installation and grouting, and spray dust reduction into an integrated trolley, which greatly reduces the connection waiting time of each construction operation process, the waiting time of the machine operation, and the number of professional operators, and reduces the difficulty of machine scheduling;

[0022] (2) This equipment completely solves the current situation where multiple machines are transferred and dispatched at the tunnel construction site and construction workers coexist in the same complex environment, greatly improving the safety of construction workers and construction machinery.

[0023] (3) This construction method can effectively solve the construction mode of the large machine supporting construction machinery transferring back and forth and alternating operations, greatly improving the construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The walking tracks 502 are generally arranged in pairs. In the non - working state, the support and roller component 503 retracts into the gantry 3 under the action of the sprocket - chain drive component 501. Before retracting, the axial swing oil cylinder 506 rotates counter - clockwise by 90°, turning the drilling - anchoring - grouting integrated working device 508 towards the outside of the gantry 3. Preferably, the retraction distance should be greater than or equal to the maximum length of the rock - drilling and grouting arm module 5. In the working state, it extends to the front - most end of the gantry 3, and the axial swing oil cylinder 506 rotates clockwise by 90°, restoring the drilling - anchoring - grouting integrated working device 508 to the vertical state shown in the figure.

Under the combined pitching actions of the pitching swing oil cylinder 504, the multi - stage telescopic arm 505, the axial swing oil cylinder 506, the radial swing oil cylinder 507, and the drilling - anchoring - grouting integrated working device 508, the full coverage of rock - drilling and hole - making on the heading face 1801 and the integrated operation of drilling, anchoring, and grouting of the advanced small - diameter pipe can be realized.

[0042] See Figure 4 、 Figure 5, This state is for the charging wet shotcreting boom to extend and unfold, face charging, and wet shotcreting state. The charging wet shotcreting boom module 12 includes a sprocket chain drive component 1201, a traveling track 1202, a support and roller component 1203, a pitching swing cylinder 1204, a multi-stage telescopic boom 1205, a hanging basket balance cylinder 1206, an artificial charging hanging basket 1207, and a wet shotcreting assembly 1208. The traveling tracks 1202 are generally arranged in pairs; in the non-working state, the support and roller component 1203 retracts into the gantry 3 under the action of the sprocket chain drive component 1201, and preferably the retraction distance should be greater than or equal to the maximum length of the charging wet shotcreting boom module 12, and extends to the front end of the gantry 3 in the working state; the pitching swing cylinder 1204 has the functions of pitching and left-right swinging; the main function of the hanging basket balance cylinder 1206 is to keep the hanging basket 1207 level and assist in adjusting the spraying angle of the wet shotcreting assembly 1208, and the wet shotcreting assembly 1208 itself has the ability of radial rotation and axial rotation ≥±90°; under the combined action of the pitching swing cylinder 1204, the multi-stage telescopic boom 1205, the hanging basket balance cylinder 1206 and the artificial charging hanging basket 1207, full coverage of face 1801 charging can be achieved; under the combined action of the pitching swing cylinder 1204, the multi-stage telescopic boom 1205, the hanging basket balance cylinder 1206 and the wet shotcreting assembly 1208, full coverage of wet shotcreting (primary shotcreting 3 cm - 6 cm and secondary shotcreting) operation for one footage of face 1801 and tunnel body 1802 can be achieved. When in the wet shotcreting state of face 1801, the artificial charging hanging basket 1207 can be quickly disassembled and detached from the charging wet shotcreting boom module 12. On the one hand, it can save energy and reduce consumption during wet shotcreting, and on the other hand, it can provide a better view for wet shotcreting.

[0043] See Figure 6 , Figure 7, This state is the state of under-excavation trimming and risk removal after the face blasting. The under-excavation risk removal operation arm module 14 includes a sliding component 1401, a slewing drive 1402, a mounting seat 1403, a main arm pitching oil cylinder 1404, a main arm 1405, a vibratory hammer 1406, a vibratory hammer pitching oil cylinder 1407, a secondary arm 1408, and a secondary arm pitching oil cylinder 1409. The sliding component 1401 can slide left and right at the front of the gantry 3 and bear the axial and radial loads transmitted by the front operations. On the one hand, by moving left and right, it can greatly reduce the lengths of the main arm 1405 and the secondary arm 1408 to cover the entire tunnel body 1802. On the other hand, during rock drilling, bolt rod placement and grouting, and wet shotcreting with explosives, it can avoid each working arm by changing its position. The slewing drive 1402 is bolted to the mounting seat 1403 and the sliding component 1401 on its upper and lower sides respectively. It is a finished component of a mature motor, motor + worm and gear + slewing bearing, which can achieve 360° rotation and bear axial and radial loads. The mounting seat 1403 provides support for the main arm pitching oil cylinder 1404 and the main arm 1405. The combined action of the main arm pitching oil cylinder 1404, the main arm 1405, the vibratory hammer 1406, the vibratory hammer pitching oil cylinder 1407, the secondary arm 1408, and the secondary arm pitching oil cylinder 1409 can realize the under-excavation trimming and risk removal operations at different heights and different distances in front of the tunnel body 1802, and can also handle the trimming work of the face 1801.

[0044] See Figure 8, This state is the state of receiving and lifting the steel arch. The steel arch installation system 11 includes single or multiple steel arches 1101 to be lifted, transported, and jacked for installation, a swinging device 1102, a lifting power device 1103, a transfer walking and lifting component 1104, a receiving and installation disc structural member 1105, a walking track 1106, and an intermediate transfer row column 1107. The single or multiple steel arches 1101 are assembled and formed with the steel mesh and connecting bars on them at the tunnel entrance or in the processing plant, transported from the tunnel entrance to the swinging device 1102 by a transportation tool, and through clockwise swinging and its up and down lifting on the lifting power device 1103, the single or multiple steel arches 1101 are lifted twice on the swinging device 1102 to reach the receiving height position of the predetermined receiving and installation disc structural member 1105 and wait for receiving. There are 2 sets of swinging devices 1102, one set on each side, symmetrically arranged, and rotated 360° through a common rotary drive to compensate for the lifting height through rotation. There are 2 sets of lifting power devices 1103, one set on each side, symmetrically arranged, providing the lifting power for the swinging device 1102, and its power form can be a conventional sprocket chain drive, or a gear rack drive, or a hydraulic cylinder drive, etc. The power receiving and installation disc structural member 1105 has two positions, the front position is the steel arch installation position, and the rear position is the steel arch receiving position. When receiving, the power receiving and installation disc structural member 1105 is at the lowest position, 2 cm to 10 cm lower than the highest position of the single or multiple steel arches 1101. When installing, the power receiving and installation disc structural member 1105 is at the highest position, close to the tunnel body 1802. There are 2 sets of transfer walking and lifting components 1104, one set on each side, symmetrically arranged, bolted to the receiving and installation disc structural member 1105 at the upper part and rolling on the walking track 1106 at the lower part. Its walking power can be a conventional sprocket chain drive, or a gear rack drive, or a hydraulic cylinder drive, etc. The lifting of the transfer walking and lifting component 1104 is driven by a common hydraulic cylinder + sleeve form. The walking tracks 1106 are generally arranged in pairs and used in supporting the transfer walking and lifting component 1104. The intermediate transfer row column 1107 is bolted to the top of the gantry 3 at the middle positions on both sides.

[0045] See Figure 9 , This state is the state of the receiving and installation disc structural member receiving materials. The receiving and installation disc structural member 1105 is moved under the steel arch through the transfer walking and lifting component 1104. The transfer walking and lifting component 1104 lifts, and the single or multiple steel arches 1101 are separated from the swinging device 1102 and transferred forward to the intermediate transfer row column 1107. During the transfer process, the bottom of the single or multiple steel arches 1101 is raised 2 cm to 10 cm relative to the corresponding position of the intermediate transfer row column 1107.

[0046] See Figure 10, This state is the transposition state of single or multiple steel arch frames 1101 on the material receiving and installation disc structure member. The material receiving and installation disc structure member 1105 moves to directly above the middle transposition row column 1107 through the transfer walking and lifting assembly 1104. The transfer walking and lifting assembly 1104 descends, driving the material receiving and installation disc structure member 1105 to descend until the single or multiple steel arch frames 1101 are 2 cm to 10 cm away from the upper surface of the material receiving position of the material receiving and installation disc structure member 1105, and the single or multiple steel arch frames 1101 are supported by the upper part of the middle transposition row column 1107; the transposition of the single or multiple steel arch frames 1101 is just the opposite of the process of lowering them to the middle transposition row column 1107. The transfer walking and lifting assembly 1104 moves backward, driving the material receiving and installation disc structure member 1105 to move backward. The installation position at the front of the material receiving and installation disc structure member 1105 moves to directly in the middle of the middle transposition row column 1107, directly below the single or multiple steel arch frames 1101. The transfer walking and lifting assembly 1104 lifts, and the single or multiple steel arch frames 1101 are separated from the middle transposition row column 1107. After the bottom of the single or multiple steel arch frames 1101 is raised 2 cm to 10 cm relative to the corresponding position of the middle transposition row column 1107, it continues to move forward (towards the tunnel face 1801).

[0047] See Figure 10 Figure 11 , Figure 10 Figure 12 , This state is when the single or multiple steel arch frames 1101 reach the foremost position and start the jacking and installation state. The transfer walking and lifting assembly 1104 moves the material receiving and installation disc structure member 1105 and the single or multiple steel arch frames 1101 thereon to the very front of the equipment. The transfer walking and lifting assembly 1104 continues to lift until the upper part of the single or multiple steel arch frames 1101 closely adheres to the tunnel wall 1802. The rock drilling and grouting arm module 5 starts to drill and install the locking foot bolts to fix the steel arch frame. At the same time, the operators weld and fix the current steel arch frame to the previous steel arch frame through the connecting bars to form an integral whole.

[0048] See Figure 10 Figure 11 , Twelve , The single or multiple steel arch frames in the tunnel reach the foremost position and start the jacking and installation state.

[0049] See Figure 10 Figure 13, This state is the drilling, anchoring and grouting operation state of the system anchor bolts and the foot-locking anchor bolts. The integrated drilling, anchoring and grouting working device 508 extends to the foremost end of the gantry 3. Through the combined action of the pitching swing cylinder 504, the multi-stage telescopic arm 505, the axial swing cylinder 506, the radial swing cylinder 507 and the pitching action of the integrated drilling, anchoring and grouting working device 508, the integrated construction operation of the system anchor bolts (radial) and the foot-locking anchor bolts of the steel arch in a standard footage of the tunnel body 1802 is realized. After the anchor bolt construction is completed, the wet shotcrete boom module 12 performs secondary spraying on the area of the current single or multiple steel arches 1101, and sprays until the concrete completely covers the lower part of the steel arch.
