Description

Inclined shaft construction method and construction system

Technical Field

The invention belongs to the technical field of tunneling, and particularly relates to a construction method and a construction system for an inclined shaft.

Background

Inclined shaft tunnels are used in the fields of pumped storage, mines and the like. The traditional inclined shaft construction still adopts the method that a raise boring machine is used for excavating pilot tunnel firstly, and then the blasting mode is utilized for carrying out the expansion and excavation construction so as to achieve the design hole diameter. However, the tunnel formed by the blasting method has poor quality and low precision, and has a great potential safety hazard.

The mechanical construction method using the full-face tunnel boring machine has the advantages of high efficiency, good safety and the like, and is also applied to inclined shaft construction in recent years. Inclined shaft construction systems generally include an originating rack that provides support for the tunneling apparatus prior to entry into the tunnel, and a tunneling apparatus that functions as both a forward propulsion and support. In order to ensure stability and safety in the tunneling process, pipe joint support is generally used synchronously in the excavating process. The existing manners for realizing the pipe piece support are generally two, one is based on the existing shield machine, namely, a pipe piece splicing machine and a pipe piece material conveying system are configured, and after each tunneling process, the pipe piece is spliced into pipe sections on site; and the other is based on the existing pipe pushing machine, a pushing system is configured, and the pushing system is used for pushing all the pipe joints which are looped and the main machine of the heading machine simultaneously.

For inclined shaft tunnels with smaller diameters, such as tunnels with the diameter of about 3m, the inner space is narrow, the pipe segment erector and the pipe segment material conveying system are difficult to arrange, and the inclined shaft tunnel is more suitable for construction by adopting a pipe push bench. However, unlike a horizontally tunneling tunnel, when a pipe-jacking machine is used for tunneling an inclined shaft tunnel, a part of the component force of the gravity of the pipe joint directly acts on the pushing system, and in order to meet the pushing force of the main machine of the tunneling machine for pushing broken rock, particularly a hard rock tunnel with higher surrounding rock grade, the inclined shaft tunnel needs to be provided with an oil cylinder with higher power, but in practice, the price of the oil cylinder with higher gauge is far higher than that of an oil cylinder with common specification, which can cause the overall high cost of inclined shaft construction.

For small diameter tunnels, push bench has many applications. However, a part of the weight of the pipe joint of the inclined shaft tunnel can act on the pipe joint pushing device, and the pushing force of the main machine for breaking rock is added, so that a pipe joint pushing oil cylinder with higher gauge needs to be arranged. However, the high-specification pipe joint pushing cylinder has higher price, so that the whole inclined shaft construction system has higher cost.

In order to solve the problems, the core technical concept of the invention is that the jacking force of the main machine for breaking the rock and the jacking force of the pipe joint for forward pushing are respectively provided by two cylinders, the supporting device on the main machine is used for supporting the tunnel wall and the self-contained pushing cylinder of the main machine for forward pushing the broken rock, the pipe joint pushing cylinder only needs to push the pipe joint and the supporting device of the main machine for forward pushing, the main machine pushing cylinder and the pipe joint pushing cylinder can be cylinders with small specifications, and the whole cost is still lower.

In order to avoid the slip of the main machine 1 of the heading machine relative to the movable frame 301 when the movable frame 301 swings and rises, the movable frame 301 is further provided with a stopping device for limiting the position of the main machine 1 of the heading machine, specifically, the stopping device in this embodiment is a stopping pin 305, and the stopping pin 305 can be inserted into a corresponding position of the main machine 1 of the heading machine.

Of course, the supporting shield 101 can also directly adopt the supporting shield 101 on the double-shield TBM in the prior art, and the basic function of the supporting shield is to tightly support the tunnel wall by using the supporting shoes.

In order to avoid slipping of the heading machine host 1 off the originating bench 3 at the time of originating, the present embodiment provides a retaining hole (not shown in the figure) in the support shield 101 for a plug-in engagement with the retaining pin 305.

In addition, in order to meet the smooth discharge of the dregs, the back of the cutter head 104 is also provided with a dregs plate, a belt conveyor is arranged in the center of the excavation bin between the cutter head 104 and the front shield 105, and the dregs plate scoops the excavated rock dregs and then falls on the belt conveyor to be conveyed backwards.

The conveying equipment for conveying the pipe piece or other materials comprises a pipe piece crane 4, wherein the pipe piece crane 4 is arranged above the pipe section pushing device 2 and plays a role in lifting the pipe piece from the rear to the position of the pipe section pushing device 2. The split type pipe piece 501 lifted by the pipe piece crane 4 is shown in fig. 5, the pipe section 5 can be formed by splicing three split type pipe sections 501 by bolts 502, and the concrete pipe piece 501 can be a steel pipe piece or a concrete pipe piece. In other embodiments, the pipe joint 5 may be assembled in advance from the outside, and lifted directly from the pipe segment crane 4 to the position of the pipe joint pushing device 2.

The embodiment mainly comprises the following steps when in construction:

s1, performing foundation construction in an originating hole, assembling the originating rack 3, and retracting an adjusting oil cylinder 302 of the originating rack 3 to enable the movable rack 301 to be in a horizontal state.

S2, assembling the main machine 1 of the heading machine outside the hole, conveying the main machine 1 to a movable frame 301 of the starting bench 3, or directly assembling the main machine 1 of the heading machine inside the hole, conveying the main machine to the movable frame 301, inserting a stop pin 305 into a stop hole of the supporting shield 101, and extending an adjusting oil cylinder 302 of the starting bench 3 to enable the main machine 1 of the heading machine to be in a certain gradient state.

S3: after the pipe joint pushing cylinder 201 extends out and the pushing plate 202 is propped to the bottom of the supporting shield 101, the stop pin 305 is pulled out from the stop hole of the supporting shield 101, the pushing plate 202 is stressed, a supporting reaction force is provided for forward pushing of the main engine pushing cylinder 102, debugging equipment is started, and jacking is prepared.

S4: the main drive 109 drives the cutterhead 104 to rotate, the main engine propulsion oil cylinder 102 stretches out, the cutterhead 104 cuts the face, and slag stones fall into the belt conveyor through a slag plate on the back of the cutterhead 104 and are discharged backwards. Meanwhile, the posture of the front shield 105 can be adjusted through the hinged oil cylinder 106, so that the construction precision is improved; the rock slag is discharged out of the main machine through the belt conveyor, and along with the extension of the pipe joint 5, the rock slag is discharged out of the hole through the slag chute 503 by means of self gravity and the existing initial speed, so that slag discharge is realized.

S5: after the cutter head 104 is tunneled to a set distance, the stop pin 305 is inserted into a stop hole of a pipe joint, the pipe joint pushing oil cylinder is retracted, the pipe piece crane 4 lifts the pipe piece to an assembling position, and after the assembly of the segmented pipe piece 501 is completed, the stop pin 305 is pulled out of the stop hole of the pipe joint 5, and the host is propelled.

S6: repeating the step 4-5 until the host completely enters the rock stratum;

s7: the supporting shoe device of the supporting shield 101 stretches out to tightly support the wall of the hole, the main drive drives the cutterhead to rotate, the main engine propulsion oil cylinder stretches out to push the cutterhead to tunnel to a set distance (the annular width of the pipe joint 5);

s8: the stop pin is inserted into a stop hole of the pipe joint, the main engine propulsion oil cylinder is retracted, the pipe piece crane 4 lifts the pipe piece to an assembling position, and the pipe joint 5 is assembled;

s9: the retaining pin is pulled out of a retaining hole of the pipe joint, the supporting shoe device of the supporting shield 101 is retracted, the supporting state is released, the pipe joint pushing cylinder 201 pushes the pipe joint 5 and the supporting shield 101 to rise to a set distance (the annular width of the pipe piece 5), the main machine pushing cylinder 102 is retracted synchronously in the rising process, and the pipe joint pushing cylinder and the pipe joint play a role in supporting the tail of the main machine 1 of the heading machine in the retracting process;

s10: repeating the steps 7-9 to finish the construction of the inclined shaft;

s11: after the host computer goes out of the tunnel, the host computer is directly transferred to the next position from the upper part for construction.

As can be seen from the analysis of the above process, after the main machine enters the hole, the thrust force required by the main machine 1 of the heading machine to press the broken rock forward in this embodiment is provided by the main machine thrust cylinder 102 and the support shield 101. The pipe joint pushing cylinder 201 only pushes the pipe joint 5 and the supporting shield 101 for retracting the supporting shoe, that is, a bearing part (which may be an end face of the supporting shield shell 1011) for bearing the thrust of the pipe joint is arranged on the supporting shield 101. Therefore, the main engine propulsion cylinder 102 and the pipe joint pushing cylinder 201 do not need to select cylinders with higher specifications, and the overall cost is still lower.

In this embodiment, in order to ensure the stability of the support, a support device that provides a support reaction force for the main engine propulsion cylinder 102 is selected as the support shield 101. In other embodiments, the supporting device may be a structure of an inner supporting beam and supporting shoes, the supporting shoes are sleeved on the periphery of the inner supporting beam and may be in an X-shaped arrangement, retaining holes matched with retaining pins of the starting platform 3 are formed in the main beam, and a bearing part for bearing the thrust of the pipe joint is formed in the inner supporting beam.

Meanwhile, in order to control the posture of the front shield and facilitate direction adjustment, the main machine 1 of the heading machine of the embodiment is further provided with a telescopic outer shield connected with the front shield 105 through a hinged oil cylinder, and in other embodiments, the main machine propulsion oil cylinder has certain direction adjustment capability and can be not provided with the telescopic outer shield. At this time, one end of the main engine propulsion cylinder may be directly connected to the front shield, that is, the front shield body of the main engine propulsion cylinder has only the front shield.

In this embodiment, when the host starts, the pipe joint pushing cylinder 201 provides a supporting reaction force for the host pushing cylinder, and in other embodiments, regarding the construction method, the supporting shield 101 and the starting bench 3 may not be separated, i.e. the stopping pin is not pulled out first, and the starting bench 3 is used to fix the position of the supporting shield 101, so as to provide a supporting reaction force for the host pushing cylinder.

In other embodiments, the support shield 101 or other form of support means may also be provided with connection structures for connection to the pipe sections, so that when the first pipe section is installed, the pipe section is connected to the support shield 101 or other form of support means and the pipe sections installed later are connected one after the other. Thus, after the main machine 1 of the heading machine enters a tunnel, the supporting shield 101 supports the tunnel wall tightly, and the tension at a determined position can be ensured for the pipe joint at the rear side of the main machine through the connecting structure.
