This is very important for cities with heavy traffic, dense population, numerous ground buildings and complex underground pipelines, which will create a clean, comfortable and beautiful environment for the cities.
The pipe-jacking construction is a construction method of underground pipelines developed after shield construction, does not need to excavate a surface layer, and can pass through highways, railways, rivers, ground buildings, underground structures, various underground pipelines and the like. In the pipe jacking construction, by means of the thrust of a main jacking oil cylinder, an inter-pipeline relay and the like, a tool pipe or a heading machine is pushed from a working well through a soil layer until the tool pipe or the heading machine is hoisted in a receiving well. Meanwhile, the pipeline following the tool pipe or the heading machine is buried between the two wells, so that the construction method for laying the underground pipeline without excavating is realized.
In the construction of rock layer pipe jacking, the blade is seriously worn. The jacking head with the larger cross section area makes the jacking pipe construction difficult to advance under the action of front rocks, and the traditional method is to cut small pits on the upper layer of the rocks and crush rock layers from the upper part, so that the jacking pipe tunneling construction efficiency is reduced, and the construction period is prolonged.
If the strength of the large sheet on the top is large enough, the driving of the top with a large section in the rock layer needs a large-power device for driving. Under the condition of considering the cost, most of power equipment cannot meet the requirement that the large-section ejector head can quickly and comprehensively crush and tunnel the rock stratum. On the basis of current power equipment, adopt the drill bit to make a hole on the rock layer working face that the top was tunneled to reduce the intensity of rock layer, the blade on the top of being convenient for is lower to the cutting of rock layer, and the efficiency of construction of this kind of mode is lower.
Therefore, the problems of difficult tunneling and insufficient power of low-cost power equipment exist in the large-section pipe jacking construction of the rock layer, so that the design of the pipe jacking device which is based on the existing power equipment and is convenient for efficient large-section pipe jacking construction is necessary.
The invention designs a municipal pipe jacking device easy to construct, and solves the problems.

As shown in fig. 1, 2 and 3, firstly, the hydraulic column B54 is started to lock the relative rotation between the cylindrical shell 12 and the gear ring C24, and the power device 31 is started to drive the round block 10 to drive the tool post a6 and the tool bit 8 on the tool post B9 to cut and tunnel the front rock working face; secondly, unlocking the relative rotation locking of the cylindrical shell 12 and the gear ring C24, locking the relative rotation of the cylindrical shell 12 and the cylinder 1, driving the rotating shaft 32 to drive the drill bit 33 to feed and drill a rock stratum working surface by starting the power equipment 31, and retracting the drill bit 33 after the drilling is finished; finally, the relative rotation of the cylindrical shell 12 and the ring gear C24 is locked again, and the power unit 31 is started to perform normal excavation.
In the invention, a large gap is formed between the inner wall of the cylinder 1 and the outer cylindrical surface of the cylindrical shell 12, so that rock stratum scraps and silt cut by the cutter head 8 can reach the spiral lifting device 68 through the gap between the inner wall of the cylinder 1 and the outer cylindrical surface of the cylindrical shell 12, and further can be timely and effectively cleaned by the spiral lifting device 68.
The power plant 31 and the screw lift 68 of the present invention are both of the prior art.
The working process of the invention is as follows: in the initial state, the drill 33 is located in the movable hole 7 of the corresponding tool apron a6, the stop block 63 located inside the cylindrical shell 12 in the sliding sleeve 61 is inserted into the corresponding stop groove a67 of the gear ring C24 to lock the relative rotation of the gear ring C24 and the cylindrical shell 12, the stop block 63 located outside the cylindrical shell 12 in the sliding sleeve 61 is not inserted into the stop groove B3 on the inner wall of the cylinder 1, and the stop block 63 located outside the cylindrical shell 12 is opposite to the corresponding stop groove B3 on the inner wall of the cylinder 1.
When the pipe jacking construction method is used for pipe jacking construction, the power equipment 31 is started firstly, the output shaft of the power equipment 31 drives the gear A29 to rotate, the gear A29 drives the gear ring A20 to rotate relative to the cylindrical shell 12 through the three gears B26, the gear ring A20 drives the gear ring B22 to rotate relative to the cylindrical shell 12 through the three gears C27, and the gear ring B22 drives the gear ring C24 to rotate relative to the cylindrical shell 12 through the three gears D28. Since the relative rotation of ring gear C24 and cylinder shell 12 is locked by five stoppers 63, ring gear C24 does not rotate relative to cylinder shell 12 but brings cylinder shell 12 into synchronous rotation relative to cylinder 1. The cylindrical shell 12 drives six tool apron A6 and tool apron B9 to rotate through the connecting column 11 and the round block 10, the six tool apron A6 drives the circular ring A4 to rotate relative to the cylinder 1, and the tool bits 8 on the tool apron A6 and the tool apron B9 drill and tunnel a rock stratum working face.
Meanwhile, the cylindrical shell 12 drives all the rotating shafts 32 and the drill bits 33 on the rotating shafts 32 to revolve around the central axis of the circular block 10, the cylindrical shell 12 drives the ring plate D50 to rotate relative to the ring plate E52 through the ring sleeve B46 and the ring sleeve C48 which are axially slidably matched with each other, and the all the rotating shafts 32 drive the ring plate B40 to rotate relative to the ring plate C42 through the ring plate a36 and the shaft sleeve 39 which are rotationally matched with the rotating shafts.
When the cutter head 8 on the cutter seat A6 and the cutter seat B9 meets hard rock stratum working faces and drilling and tunneling are difficult, all the hydraulic columns B54 are controlled to extend, the hydraulic columns B54 simultaneously drive five sliding blocks 58 to slide on the end face of the cylindrical shell 12 in the direction away from the central axis of the cylinder 1 along the radial direction through a ring sleeve C48 and five connecting rods 66, the five sliding blocks 58 respectively drive corresponding sliding sleeves 61 to synchronously move through corresponding L-shaped rods 60, each sliding sleeve 61 drives corresponding two limiting blocks 63 to synchronously move through a pressure spring 65 and a guide block B64, and the five limiting blocks 63 close to the central axis of the cylinder 1 are quickly separated from corresponding limiting grooves A67 and lock the gear ring C24 and the cylindrical shell 12 to rotate relatively. If the five limit blocks 63 far away from the central axis of the cylinder 1 are not opposite to the corresponding limit grooves B3 on the inner wall of the cylinder 1, the five limit blocks 63 far away from the central axis of the cylinder 1 will quickly abut against the inner wall of the cylinder 1, and the pressure spring 65 is further compressed to store energy. With the continuous rotation of the cylindrical shell 12, the five limit blocks 63 far away from the central axis of the cylinder 1 finally respectively oppose the corresponding limit grooves B3 and are instantly inserted into the corresponding limit grooves B3 under the reset action of the corresponding pressure springs 65 to complete the locking of the relative rotation of the cylindrical shell 12 and the cylinder 1. If the five limit blocks 63 far away from the central axis of the cylinder 1 are right opposite to the corresponding limit grooves B3 on the inner wall of the cylinder 1, the five limit blocks 63 far away from the central axis of the cylinder 1 are quickly inserted into the corresponding limit grooves B3 to quickly complete the locking of the relative rotation of the cylinder shell 12 and the cylinder 1.
At the moment when the relative rotation of the cylinder case 12 and the cylinder 1 is locked, the rotation of the cylinder case 12 with respect to the cylinder 1 is stopped, the rotation of the tool holder a6 and the tool holder B9 is stopped, and the entire rotary shaft 32 and the drill 33 are stopped from revolving around the central axis of the cylinder 1. The output shaft of the power device 31 drives the gear A29 to rotate relative to the cylindrical shell 12, the gear A29 drives the three gears B26 to rotate, the three gears B26 drives the gear ring A20 to rotate relative to the cylindrical shell 12, and the gear ring A20 drives the three gears C27 meshed with the gear ring A and six gears E34 in the same circle to rotate. The three gears C27 drive the gear ring B22 to rotate relative to the cylindrical shell 12, and the gear ring B22 drives the three gears D28 meshed with the gear ring and six gears E34 in the same circle to rotate. The three gears D28 drive the ring gear C24 to rotate relative to the cylindrical shell 12, and the ring gear C24 drives the six gears E34 which are meshed with and in the same circle to rotate. Six sets of eighteen shafts 32 are driven by gears E34 to rotate relative to cylindrical shell 12.
And starting all the hydraulic columns A44 to perform extension movement, driving all the rapidly-rotating shafts 32 to axially move towards the rock stratum working face relative to the cylindrical shell 12 by the hydraulic columns A44 through the shaft sleeve 39 and the ring plate A36, and driving the drill bit 33 at the tail end of the rotating shafts 32 to drill the rock stratum working face. When the drilling depth of the drill bit 33 reaches the requirement, all the hydraulic columns A44 are controlled to perform contraction movement, and the hydraulic columns A44 drive the drill bit 33 on the rotating shaft 32 to quickly break away from the drilling hole on the rock stratum working surface through the shaft sleeve 39 and the ring plate A36. And then all the hydraulic columns B54 are started to perform contraction movement, the hydraulic columns B54 drive the five limit blocks 63 far away from the central axis of the cylinder 1 to quickly separate from the corresponding limit grooves B3 through a series of transmission, the locking of the relative rotation of the cylinder shell 12 and the cylinder 1 is released, and meanwhile, the five limit blocks 63 close to the central axis of the cylinder 1 quickly move towards the gear ring C24.
If the five stoppers 63 near the central axis of the cylinder 1 are not opposed to the corresponding stopper grooves a67 on the inner wall of the cylinder 1, the five stoppers 63 near the central axis of the cylinder 1 are quickly abutted against the ring gear C24, and the pressure spring 65 is further compressed to store energy. With the gear ring C24 continuing to rotate relative to the cylindrical shell 12, the five limit blocks 63 near the central axis of the cylinder 1 finally respectively oppose the corresponding limit grooves a67 and are momentarily inserted into the corresponding limit grooves a67 under the reset action of the corresponding pressure springs 65 to complete the locking of the relative rotation of the cylindrical shell 12 and the gear ring C24. If the five limit blocks 63 close to the central axis of the cylinder 1 are just opposite to the corresponding limit grooves A67 on the gear ring C24, the five limit blocks 63 close to the central axis of the cylinder 1 are quickly inserted into the corresponding limit grooves A67 to quickly lock the relative rotation of the cylinder shell 12 and the gear ring C24. While the gear ring C24 and the cylindrical shell 12 are locked in relative rotation, the power device 31 drives the cylindrical shell 12 to rotate relative to the cylinder 1 through a series of transmissions, and the cylindrical shell 12 drives five limiting blocks 63 far away from the central axis of the cylinder 1 through five sliding sleeves 61 to be staggered with corresponding limiting grooves B3 and move towards the direction of the next limiting groove B3. When the limiting blocks 63 are not opposite to the corresponding limiting grooves B3, all the hydraulic columns B54 are started to perform extension movement, the hydraulic columns B54 drive the five limiting blocks 63 far away from the central axis of the cylinder 1 to quickly abut against the inner wall of the cylinder 1 through a series of transmission, the pressure spring 65 is further compressed to store energy, the five limiting blocks 63 close to the central axis of the cylinder 1 quickly separate from the corresponding limiting grooves A67, and the locking of the gear ring C24 and the cylinder shell 12 in relative rotation is released. When the five limit blocks 63 far away from the central axis of the cylinder 1 are opposite to the corresponding limit grooves B3, the five limit blocks 63 far away from the central axis of the cylinder 1 are instantaneously inserted into the corresponding limit grooves B3 under the reset action of the corresponding pressure springs 65 and complete the locking of the relative rotation of the cylinder shell 12 and the cylinder 1. At this time, the power device 31 drives all the drill bits 33 to rotate rapidly through a series of transmission, all the rotating shafts 32 and the drill bits 33 on the rotating shafts 32 revolve around the central axis of the cylinder 1 by 72 degrees on the basis of the previous drilling, and the drill bits 33 revolve to between two adjacent drilling holes on the same circle. The entire hydraulic column a44 is activated to perform the extension movement again, and the hydraulic column a44 drives the entire drill bit 33 through a series of transmissions to drill the formation face again. Since the six sets of boreholes drilled this time are staggered from the six previously drilled sets of boreholes.
Thus, the relative rotation between the cylindrical shell 12 and the cylinder 1 is locked and unlocked continuously for four times, so that the drilled holes drilled by the six groups of drill bits 33 at each time are staggered with the previous six groups of drilled holes, the radian between two adjacent drilled holes on the same circle is smaller and does not coincide, the density of the drilled holes on the rock stratum working face is increased, the actual action area of the rock stratum working face and the tool bit 8 is effectively reduced, and the tool bit 8 on the tool bit A6 and the tool bit B9 can drill and tunnel harder rock strata more easily. When the drill bit 33 finishes drilling and retracts to the initial position, all the hydraulic columns B54 are started to retract, the hydraulic columns B54 drive five limiting blocks 63 close to the central axis of the cylinder 1 through a series of transmissions to quickly lock the gear ring C24 and the cylinder shell 12 to rotate relatively, and the power equipment 31 drives the cutter head 8 on the cutter seat A6 and the cutter seat B9 to efficiently drill and tunnel the rock stratum working face full of drilled holes through a series of transmissions.
The actual action area of the cutter head 8 on the rock stratum working face, the cutter seat A6 and the cutter seat B9 is effectively reduced by drilling holes in the rock stratum working face, so that the cutter head 8 can drill and tunnel the rock stratum more easily, and the working efficiency of pipe jacking construction is improved.
During the drilling and excavation of the rock formation, rock formation debris or silt is conveyed to the ground by the spiral lifting device 68 for deslagging. When the pipe jacking construction is finished, the operation of the power equipment 31 is stopped.
In conclusion, the beneficial effects of the invention are as follows: according to the invention, the cutter seat A6 and the cutter seat B9 stop tunneling when encountering harder rock layers, the drill bits 33 of the plurality of rotating shafts 32 with smaller diameters are used for drilling the working surface of the harder rock layers, so that the strength of the working surface of the harder rock layers is reduced, then the cutter seat A6 and the cutter seat B9 are driven to drive the cutter head 8 arranged on the cutter seat A6 and the cutter seat B9 to cut and tunnel the working surface of the rock layers which are fully drilled, the abrasion of the cutter head 8 on the cutter seat A6 and the cutter seat B9 is effectively reduced, the service life of the cutter head 8 is prolonged, the maintenance cost is reduced, and the efficiency of pipe jacking construction is improved. Meanwhile, the driving of the working face of a harder rock stratum can be completed by effectively utilizing the power equipment 31 with lower power through the mode of reducing the rock stratum strength by drilling with the drill bit 33 on the rotating shaft 32, the efficiency of pipe jacking construction is further improved, and the cost of the power equipment 31 is reduced.
