It is used for evacuation of personnel in the event of an accident, and it is also convenient for rescue workers to quickly carry out rescue work. The construction method usually used for the communication channel is the frozen soil method, but this method has the disadvantages of long freezing time, difficult to control ground subsidence, low construction efficiency, and high project cost.

[0043] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] See Figures 1 to 8 As shown, a connection channel construction equipment capable of synchronous construction includes: a tunneling mechanism 1 for tunneling the connection channel; a main trolley 2 for carrying and transporting the tunneling mechanism 1, the main trolley 2 includes a lifting platform 201, and the lifting platform 201 is located at the starting and ending positions of the connection channel; a translation device 3 for translating the tunneling mechanism 1, the translation device 3 includes a translation track 301, and the translation track 301 is used to be placed in the connection channel; a reaction force support assembly 64 for transmitting the reaction force during the tunneling of the tunneling mechanism 1 to the main tunnel segment 12, the reaction force support assembly 64 includes a support frame through which the main tunnel construction vehicle 9 can pass, and the support frame is used to support on the side of the main tunnel away from the connection channel; a propulsion device 5 for propelling the tunneling mechanism 1, the propulsion device 5 includes a propulsion drive 502, and the propulsion drive 502 is located between the lifting platform 201 and the support frame; a support assembly 6 for supporting the inside and sides of the box culvert 13, and the lifting platform 201 and the support frame are placed on the support assembly 6.

[0045] The present invention is not only applicable to the main tunnel with a box culvert 13, and the main tunnel without a box culvert 13 can be adapted by slightly changing the structure; the connection channel tunneling machine of the present invention is not limited to a circular cross-section and can adapt to special-shaped cross-section types such as rectangular and horseshoe-shaped; according to different engineering situations, the connection channel may have horizontal, vertical, and inclined installation forms, and the present invention only needs to adjust the layout of the corresponding equipment to achieve various working conditions. For example Figure 3As shown, due to the narrow space inside the connection passage and the heavy weight of the main machine, it is impossible to use a crane for hoisting. Therefore, the translation device 3 can be used to translate the main machine trolley 2 to the designated position. The translation device 3 can adopt the structural form of a translation track 301 and an electric pulley. An electric pulley is installed at the bottom of the main machine trolley 2 to travel along the translation track 301. It can also adopt the structural form of a steel structure and a translation oil cylinder 302. The translation oil cylinder 302 is fixed to the steel structure, and the main machine trolley 2 is placed on the steel structure. The main machine trolley 2 is pushed forward by the translation oil cylinder 302. The oil cylinder can also be replaced by a cylinder. It can also adopt the structure of matching a gear and a rack to be able to translate the main machine trolley 2 in a step-changing manner. The support assembly 6 includes an internal support 601 of the box culvert installed inside the box culvert 13 and a side support 602 of the box culvert installed on the side of the box culvert 13.

[0046] Preferably, as Figure 2 shown, the construction equipment further includes a hoisting assembly 7 for hoisting segments and muck.

At the same time, it can realize the up and down lifting to meet the requirements of different hoisting positions and heights. The lifting frame 703 includes a plurality of oil cylinders and a transverse frame. The stepless lifting can be realized through the oil cylinders, and the transverse frame is fixed on the tops of all the oil cylinders. The traveling mechanism 702 includes a track fixed on the transverse frame and an electric pulley slidably installed on the track. The hoisting driving member 701 can adopt an electric hoist, and the electric hoist is installed on the electric pulley. Wheels are arranged at the bottom of each oil cylinder to realize the overall movement of the hoisting assembly 7. The hoisting assembly 7 can be integrally assembled outside the tunnel and towed into the tunnel.

[0047] Preferably, the tunneling mechanism 1 includes a cutter head 101, a shield 102, a driving device 103, a mucking system 104 and a deviation rectifying device 105. The cutter head 101 is fixed to the front end of the shield 102. The driving device 103, the mucking system 104 and the deviation rectifying device 105 are fixed inside the shield 102. The driving device 103 is drivingly connected to the cutter head 101. The cutter head 101 rotates to excavate the rock and soil of the working face, and is used to directly break the high-strength main tunnel segment 12. Generally, a composite cutter head is adopted, mainly in the form of full-face disc cutters, and at the same time, cutters and scrapers are configured to assist in cutting. The shield 102 is mainly used to support the stability of the surrounding strata, and at the same time provides installation interfaces for various internal devices such as the main drive, hydraulic, and electrical components. The driving device 103 is the power source for driving the rotation of the cutter head 101, and different driving types such as electric drive and hydraulic drive can be adopted. The deviation rectifying device 105 is controlled by multiple groups of articulated cylinders in a partitioned manner, and a stroke sensor is provided in each area. The turning and attitude adjustment of the tunneling machine are realized by controlling the stroke of the articulated cylinders in groups. The tunneling mechanism 1 can adopt an earth pressure balance tunneling machine, a slurry balance tunneling machine, a TBM (Full Face Rock Tunnel Boring Machine, full-face rock tunneling machine) hard rock cross-passage tunneling machine or other types of tunneling machines, or a pipe-jacking tunneling machine, a shield tunneling machine, a TBM hard rock tunneling machine or other types of tunneling machines, and can be arbitrarily combined. The method of transporting the tunneling mechanism 1 into the tunnel is not limited to transporting it into the tunnel by a flatbed truck, and it can be transported into the tunnel by means of self-provided wheel pairs.

The sealing assembly 8 can prevent groundwater from entering the main tunnel. The sealing brush 801 can adopt a wire brush structure or a rubber skin structure, etc. The sleeve is connected to the main tunnel segment 12 by welding or a detachable connection method. The sealing assembly 8 at the receiving position of the cross-passage can be installed according to the tunneling direction of the cross-passage construction equipment and each tunneling parameter and dimension, so as to smoothly complete the fully enclosed receiving work.

[0049] Preferably, the muck discharging system 104 includes a screw conveyor 1041 and a slurry pipeline 1042. A soil bin for connecting the screw conveyor 1041 and the slurry pipeline 1042 is provided behind the cutter head 101. By reserving two muck discharging methods of the screw conveyor 1041 and the slurry pipeline 1042, different muck discharging methods are adopted according to different working conditions. When the formation water pressure is small and the formation is a rock stratum, the screw conveyor 1041 is used for muck discharging. When the formation water pressure is high, the slurry pipeline 1042 can be used for muck discharging. The two modes can be quickly switched online. Further, in addition to the two muck discharging methods of the screw conveyor 1041 and the slurry pipeline 1042, the muck can also be discharged by a muck truck, and different muck discharging methods can be adopted according to different working conditions.

The upper support beam 403 is connected between the upper support shoe plate 404 and the rear backing plate 401. The lower support beam 402 is connected between the lower support shoe plate 404 and the rear backing plate 401. The shape of the support frame is similar to a box structure, and it mainly has two functions. One is to evenly transfer the reaction force during the tunneling of the tunneling machine to the main tunnel segment 12, and the other is to leave a passage for the entry and exit of materials during the construction of the main tunnel. The reaction force support system is mainly composed of steel structures and is modularly combined. The rear backing plate 401, the lower support beam 402, the upper support beam 403 and the support shoe plates 404 are connected to each other by bolts / pins and other means. The lower support beam 402 is installed in a groove reserved in advance in the main tunnel culvert 13. A buffer material such as nylon / polyurethane / rubber is applied to the outside of the support shoe plates 404 to reduce damage to the main tunnel segment 12. The support frame is made of steel structure, and it can also be connected by oil cylinders or other means as long as a box-shaped frame form is formed.

[0051] Preferably, the propulsion device 5 further includes a mounting frame 501. The number of the propulsion driving members 502 is multiple, and the multiple propulsion driving members 502 are evenly spaced and fixed on the mounting frame 501. The mounting frame 501 is attached to the rear backing plate 401. The propulsion device 5 uses the reaction force support system as the backseat force and mainly plays the role of propelling the main machine.

[0052] Preferably, the lifting platform 201 includes a plurality of lifting driving members 202, and the plurality of lifting driving members 202 are supported on the support assembly 6. One main machine trolley 2 is provided at each of the starting end and the receiving end in the two main tunnels, which mainly functions to carry and transport the tunneling mechanism 1, the starting sleeve, and the receiving sleeve, and to adjust the attitude of the main machine. In this embodiment, the lifting platform 201 is composed of a steel structure, four lifting cylinders, and a unloading tooling 203. The lifting driving member 202 can be an oil cylinder. The lifting platform 201 can quickly adjust the attitude of the tunneling mechanism 1 at various angles through the lifting driving member 202 to adapt to starting and receiving at different angles. The lifting platform 201 is generally transported into the tunnel by a flatbed truck or by its own wheels.

[0053] Preferably, the construction equipment further includes an auxiliary trolley 10 for assisting in construction, and the auxiliary trolley 10 is located in the main tunnel of the connecting passage. The auxiliary trolley is a trolley with rubber-coated wheels and is directly pulled into the tunnel as a whole from outside the tunnel. Hydraulic systems, electrical systems, control systems, grouting and friction reduction systems and other auxiliary systems are provided on the auxiliary trolley 10. The connection relationships and layout relationships among the various systems are all prior arts and will not be elaborated here.

[0054] As Figures 5 to 8 shown, the present invention also provides a construction method using the above-mentioned connecting passage construction equipment capable of synchronous construction, including the following steps:

[0055] Install the connecting passage construction equipment capable of synchronous construction in the upper main tunnel and the lower main tunnel. Specifically, install the support assembly 6 inside and on the side of the support culvert 13, install the support frame on the support assembly 6, and support the support frame on the side of the main tunnel away from the connecting passage;

[0056] Transport the tunneling mechanism 1 and the lifting platform 201 as a whole from the main tunnel to the starting portal position of the connecting passage, and install the propulsion driving member 502 between the lifting platform 201 and the support frame;

[0057] Adjust the angle of the attitude of the tunneling mechanism 1 through the lifting platform 201;

[0058] Apply a propulsion force to the tunneling mechanism 1 by the propulsion driving member 502 propping against the support frame. The tunneling mechanism 1 constructs the connecting passage from the upper main tunnel. During the construction process, the tunneling mechanism 1 and the lifting platform 201 are integrally translated forward through the translation track 301, and the main tunnel conducts synchronous construction. The main tunnel construction vehicle 9 passes through the support frame;

[0059] The construction of the connecting passage is completed, and the tunneling mechanism 1 is received in the lower main tunnel, and the connecting passage construction equipment capable of synchronous construction is disassembled.

[0060] Specifically, after the support assembly 6 is installed and before the lifting platform 201 is installed, the installation operation of the auxiliary trolley 10 is carried out. When adjusting the attitude angle of the tunneling mechanism 1 through the lifting platform 201, the attitude angle of the tunneling mechanism 1 is adjusted through multiple lifting cylinders of the lifting platform 201, which can adapt to different axis angles of the connecting passage, realize horizontal and oblique construction, then connect the sleeve with the main tunnel segment 12, and then conduct a watertight test to detect the sealing performance of the tunneling faceplate and the sleeve. After the construction of the connecting passage is completed, grouting is carried out outside the connecting passage segment 11 to stop water, the sleeves at the starting and receiving positions are removed, and then the equipment is disassembled in the reverse process.

[0061] The connecting passage construction equipment of the present invention that can be constructed synchronously provides a support platform for the connecting passage construction equipment by arranging the support assembly 6 inside and on the side of the culvert 13, solving the technical problem that the existing connecting passage construction equipment is not applicable to the connecting passage construction of the main tunnel with a culvert 13. During the construction of the connecting passage, the support frame allows the main tunnel construction vehicle 9 to pass through, so that it will not affect the tunneling and material transportation of the main tunnel boring machine, enabling the main tunnel tunneling and the connecting passage tunnel branch tunneling to be mechanized synchronously, greatly improving the construction efficiency; a method for mechanically constructing a connecting passage in a main tunnel with a culvert 13 is proposed; the T-shaped tunnel branch of the connecting passage can select different directions such as horizontal and oblique, with wide adaptability; during the entire mechanical construction process, the design change of the existing structure of the original main tunnel is small, and it has a fast method for equipment assembly, transportation, and positioning, with high efficiency.
