One end of the jacking tunneling equipment is fixed (fixed end), and the other end (jacking end) is provided with a counterforce structure (for example, a counterforce frame). The counterforce structure is connected to the fixed end of the jacking tunneling equipment through a force transmission structure (for example, a pull rod). Thus, the counterforce structure can provide a jacking force to one side of the fixed end to jacks the main machine and / or the pipe segment to be laid in the direction of the fixed end, thereby gradually punching a liaison channel between the two main tunnels of the starting end tunnel and the receiving end tunnel.

Specific implementation

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] The utility model provides a kind of pushing tunneling equipment, which is commonly used equipment in tunnel construction. For example, when tunnel construction is carried out by mechanical method, it is often necessary to involve the excavation and laying of bypass channel (such as the communication passage of subway). Taking the communication passage as an example, it needs to open the pre-supporting trolley during the construction, install and fix the pushing tunneling equipment, and face the counter-force structure of the pushing tunneling equipment to the main tunnel segment on the opposite side of the originating direction. Further, the counter-force structure is forced to push from the originating side to the receiving side, so that the pushing tunneling equipment can push the main machine and / or the to-be-laid segment to the receiving side to carry out construction.

[0024] For the basic structure and working principle of the pushing tunneling equipment, please refer to the prior art disclosed in Chinese patents CN219910759U, CN219840653U and CN218780355U (also the applicant's prior application), which will not be repeated here.

[0025] It can be understood that in addition to the bypass construction, the jacking excavation equipment also has many other application scenarios in tunnel construction. It can be used for transverse jacking, and can also be used for longitudinal or inclined jacking. In addition to subway construction, jacking excavation equipment has wide application prospects in underground pipeline laying, municipal pipe gallery construction, mining excavation and other engineering fields.

[0026] The jacking excavation equipment needs to provide jacking force through the reaction force structure to jacking the target object forward. In tunnel construction, the reaction force structure is generally a reaction force frame and a reaction force oil cylinder installed on the reaction force frame, and the target object is generally the main machine of the tunneling machine or the pipe segment to be laid.

[0027] The jacking mode of the reaction force structure in the prior art mainly includes two kinds: one is the prior art such as CN115163102B, which installs a hydraulic cylinder (equivalent to a power unit of the reaction force structure) on a fixed part to be directly connected with the fixed end, and through the action force of the hydraulic cylinder, the jacking excavation equipment pushes the target object forward; the second is the prior art such as CN218093039U, which installs a hydraulic cylinder (equivalent to a power unit) on a reaction force frame, and adopts a pull rod to connect the reaction force frame and the starting sleeve. Therefore, the jacking force provided by the hydraulic cylinder makes the pull rod be tensioned. The tension force makes the pull rod similar to the arm that grips the starting sleeve, and the tension of the arm makes the reaction force structure be able to stably jacking excavation.

[0028] Through the analysis of the prior art, it can be known that if the power unit is directly connected with the fixed end, the strong jacking force of the power unit when jacking will directly act on the fixed end, which is easy to cause damage to the fixed end, whether the fixed end is a pipe segment or a starting sleeve. Therefore, it is necessary to set a force transmission structure such as a pull rod. If the power unit is installed on the reaction force frame, and the reaction force frame and the starting sleeve are connected by the pull rod, the problem of strong force damage caused by the direct action of the power unit on the fixed end can be avoided. However, since the power unit and the reaction force frame are generally large in volume and weight, the tension provided by the reaction force structure to the pull rod will still act on the starting sleeve. This causes the starting sleeve to be subjected to excessive force, which may cause problems such as deviation and deformation, resulting in deviation of the excavation direction or obstruction of the main machine work.

[0029] In summary, for the jacking excavation equipment, it is necessary to set a force transmission structure, but how to avoid the influence and damage of the tension of the jacking excavation equipment on the starting sleeve during work is also a technical problem to be solved by those skilled in the art.

[0030] To this end, the utility model provides a kind of push advancing equipment, it is used to advance construction by originating side A to receiving side B, and push advancing equipment includes: originating sleeve 100, originating sleeve 100 is fixedly installed in originating side A;Push end 200, push end 200 includes power unit 210, and power unit 210 is used to supply power, so that push end 200 is pushed to the direction of receiving side B;Force transmission structure 300, one end of force transmission structure 300 is connected with push end 200, and the other end is fixedly installed in originating side A, and not directly connected with originating sleeve 100.

[0031] Specifically, originating sleeve 100 is used as the fixed structure of advancing starting end, and it is used to provide initial orientation and sealing function for main machine 700 of advancing equipment.The installation mode of originating sleeve 100 is fixed on the inner wall of tunnel in originating side A by pre-buried bolt or welding or concrete pedestal, and its axis coincides with the tunnel axis.The role of push end 200 is to push main machine 700 and / or to-be-installed segment 800 along originating sleeve 100 from originating side A to receiving side B.The push end 200 of the utility model includes power unit 210, and power unit 210 is installed on counter-force frame.Power unit 210 is specifically hydraulic cylinder, and it is connected with hydraulic pump by oil circuit, and hydraulic pump inputs hydraulic oil to hydraulic cylinder by control valve, and under the pressure action of hydraulic oil, the piston of hydraulic cylinder moves in cylinder barrel, thereby pushing piston rod to output push force to target object main machine 700 and / or to-be-installed segment 800.

[0032] The role of force transmission structure 300 is to transmit the counter-force of push end 200 to originating side A, so that push advancing equipment forms stable stress system.One end of force transmission structure 300 is connected with push end 200, and the other end is fixedly installed in originating side A.The above connection relationship makes the role of force transmission structure 300 similar to the arm that grips the fixed end of originating side A, and the tension of arm makes the counter-force structure including power unit 210 be able to stably push advancing.The utility model can adopt support component or structure to support and fix counter-force structure, and under the condition that equipment condition allows, force transmission structure 300 can also be selected to support counter-force structure directly.

[0033] As mentioned above, the starting sleeve 100 can provide initial guidance for the main machine 700, and the stability of the starting sleeve 100 affects the tunneling direction and the tunneling effect. In order to protect the starting sleeve 100 and avoid the tension of the force transmission structure 300 causing the starting sleeve 100 to be deformed or deviated, the connection relationship between the force transmission structure 300 and other components is improved in the utility model. Compared with the mounting and fixing mode of directly fixing the force transmission structure 300 to the starting sleeve 100 in the prior art, the utility model fixes the force transmission structure 300 at other positions, so that the force transmission structure 300 is not directly connected with the starting sleeve 100. Therefore, the utility model can avoid the problems of deviation and deformation of the starting sleeve 100 caused by strong tension.

[0034] It also needs to be explained that if the one end of the force transmission structure 300 away from the jacking end 200 is mounted and fixed to the receiving side B, the force transmission structure 300 needs to pass through the main tunnel segment to realize the installation, and this process needs to drill a hole in advance, and the construction process and the installation structure are relatively complex. Therefore, the utility model fixes the one end of the force transmission structure 300 away from the jacking end 200 to the starting side A, which not only simplifies the construction process, but also makes the structure more compact, and the construction of the starting side A is not affected by the receiving side B. Even if the receiving side B does not have construction conditions, the starting side A can still be constructed normally.

[0035] As shown in Figure 1 , in order to avoid the problems of deviation and deformation of the starting sleeve 100 caused by strong tension, the first embodiment of the utility model fixes the force transmission structure 300 to the tunnel segment 400 of the starting side A.

[0036] It can be understood that Figure 1 the tunnel segment 400 of the starting side A is the main tunnel segment of the starting side A, and the starting sleeve 100 can also be fixed to the tunnel segment 400 during the construction of the jacking tunneling equipment. The main machine 700 needs to pass through the tunnel segment 400 and jacks to the receiving side B. The tunnel segment 400 of the starting side A can be a concrete segment or a steel segment. For the steel segment, the force transmission structure 300 can be connected with the tunnel segment 400 by welding. For the concrete segment, the force transmission structure 300 can be anchored to the tunnel segment 400.

[0037] Exemplarily, as shown in Figure 1 , the anchor block 410 is installed on the tunnel segment 400, and the force transmission structure 300 is connected with the tunnel segment 400 through the anchor block 410. The anchor block 410 can be connected with the steel plate or steel bar pre-buried in the segment 400 through an anchor bolt.

[0038] As shown in Figure 2 and Figure 3As shown in the second embodiment of the utility model, the force transmission structure 300 is installed and fixed on the anchoring platform 420 of the tunnel segment 400 at the originating side A. Specifically, the tunnel segment 400 has an inner concave arc surface, and the anchoring platform 420 is arranged on the inner concave arc surface. The force transmission structure 300 is connected with the anchoring platform 420.

[0039] It can be understood that the anchoring platform 420 is a structure artificially applied on the inner concave arc surface of the tunnel segment 400. The anchoring platform 420 can be a steel structure, a concrete structure, or a reinforced concrete structure. The anchoring platform 420 not only facilitates the installation of the force transmission structure 300, but also facilitates the fixation of other structures such as the originating sleeve 100.

[0040] By installing and fixing the force transmission structure 300 on the tunnel segment 400 at the originating side A, the force transmission structure 300 can be prevented from affecting the originating sleeve 100 when subjected to tension. In addition, the tunnel segment 400 usually adopts a steel structure or a concrete structure or a reinforced concrete structure. The material properties facilitate the installation and fixation of the force transmission structure 300. The force transmission structure 300 can be reliably installed and fixed by only the anchoring block 410 and / or the anchoring platform 420.

[0041] As shown in the third embodiment of the utility model, the force transmission structure 300 is installed and fixed on the force transmission structure mounting portion 500. Specifically, the jacking and tunneling equipment further comprises a force transmission structure mounting portion 500 arranged outside the originating sleeve 100. The force transmission structure 300 is installed and fixed on the force transmission structure mounting portion 500. Figure 4 Figure 5 In other words, the utility model sets the force transmission structure mounting portion 500 for the force transmission structure 300, which is independent of the originating sleeve 100. The force transmission structure mounting portion 500 is specially used for realizing the installation and fixation of the force transmission structure 300. In order to ensure uniform stress, the force transmission structure mounting portion 500 can be sleeved on the outer periphery of the originating sleeve 100, so that the plurality of force transmission structures 300 can be uniformly arranged along the circumference of the originating sleeve 100.

[0042] The force transmission structure mounting portion 500 can be a cylindrical structure surrounding the originating sleeve 100, or a shelf or box frame structure arranged outside the originating sleeve 100. Preferably, in order to avoid transmitting the tension from the force transmission structure 300 to the originating sleeve 100, there is no connection relationship between the force transmission structure mounting portion 500 and the originating sleeve 100. The force transmission structure mounting portion 500 can be installed and fixed on the tunnel segment 400 at the originating side A.

[0043] The force transmission structure mounting portion 500 can be a cylindrical structure surrounding the originating sleeve 100, or a shelf or box frame structure arranged outside the originating sleeve 100. Preferably, in order to avoid transmitting the tension from the force transmission structure 300 to the originating sleeve 100, there is no connection relationship between the force transmission structure mounting portion 500 and the originating sleeve 100. The force transmission structure mounting portion 500 can be installed and fixed on the tunnel segment 400 at the originating side A.

[0044] ​Preferably, the force transmission structure mounting portion 500 is an outer ring sleeve which is sleeved outside the originating sleeve 100. It can be understood that the radial dimension of the outer ring sleeve is slightly larger than the originating sleeve 100, and it is connected and fixed with the tunnel segment 400 of the originating side A by anchoring or welding. The outer ring sleeve only surrounds the outer periphery of the originating sleeve 100, and the two do not directly contact.

[0045] Compared with the first and second embodiments of the utility model, by setting the force transmission structure mounting portion 500, the length of the force transmission structure 300 can be shortened, the moment can be shortened, thereby protecting the force transmission structure 300, and reducing the stress of the force transmission structure 300 away from the jacking end 200 side.

[0046] It can be understood that in the utility model, the force transmission structure 300 can be any one of a rigid force transmission structure, a flexible force transmission structure, a driving force transmission structure, and can realize force transmission. Exemplarily, the rigid force transmission structure can be a pull rod, and the pull rod can be a threaded steel pull rod. The flexible force transmission structure can be a cable. The driving force transmission structure can be an oil cylinder or an electric cylinder.

[0047] When the jacking end 200 is in a non-working state, the force transmission structure 300 is in a relaxed state and is not tensioned. When the jacking end 200 is in a working state, the force transmission structure 300 is subjected to tension and is tensioned due to the action of the power unit 210.

[0048] As shown in FIG. 1, Figures 1 to 5 In order to facilitate the installation of the force transmission structure 300, the jacking and tunneling equipment further comprises a connecting piece 600, which is used to connect the force transmission structure 300 with the originating side A and / or the jacking end 200; wherein the connecting piece 600 is connected with the originating side A and / or the jacking end 200, and at least part of the force transmission structure 300 is inserted through the connecting piece 600.

[0049] In other words, the connecting piece 600 can be arranged on the originating side A, or can be arranged on the jacking end 200. In the first embodiment of the utility model, the force transmission structure 300 is installed on the segment 400 of the originating side A through the connecting piece 600. Similarly, in the second and third embodiments of the utility model, the force transmission structure 300 is respectively installed on the anchoring platform 420 above the segment 400 and the outer ring sleeve outside the originating sleeve 100 through the connecting piece 600.

[0050] For the force transmission structure 300 in the form of a pull rod or a cable, the connecting piece 600 is preferably made of a metal piece, which is provided with a through hole, and the pull rod or the cable penetrates through the through hole to be relatively fixed with the connecting piece 600. For the force transmission structure 300 in the form of a pull rod, a nut can be used to tighten the pull rod to prevent the pull rod from coming out of the through hole of the connecting piece 600.

[0051] Preferably, to ensure uniform force transmission, the force transmission structure 300 is configured as multiple and / or multiple groups. For example, the force transmission structure 300 can be a single group, with multiple force transmission structures 300 arranged circumferentially around the starting sleeve 100. Alternatively, the force transmission structure 300 can be arranged in groups of two to six, with two to six groups of force transmission structures 300 arranged circumferentially around the starting sleeve 100.

[0052] like Figures 1 to 5 As shown, when the force transmission structure 300 is configured as multiple and / or multiple groups, at least two force transmission structures 300 in all force transmission structures 300 share a connector 600. For example, the connector 600 is provided with multiple through holes, and each force transmission structure 300 in the same group passes through a through hole into the connector 600.

[0053] The structure in which at least two of the force transmission structures 300 share a single connector 600 facilitates the installation and fixing of the force transmission structures 300, simplifies the construction process, and improves construction efficiency.

[0054] In this utility model, the force transmission structure 300 can be a single integral structure, or it can include at least two separate parts. For example... Figure 4 and Figure 5 As shown, the force transmission structure 300 includes a first force transmission component 310 and a second force transmission component 320 that are detachably connected. The first force transmission component 310 and the second force transmission component 320 can be interconnected via a connector 330. For example, the first force transmission component 310 and the second force transmission component 320 are threadedly connected to the connector 330 respectively. Setting the force transmission structure 300 as a separate and detachable structure of at least two parts facilitates the lowering of the tube segment 800 to be installed and prevents the force transmission structure 300 from obstructing the entry of the tube segment 800 between the push end 200 and the main unit 700. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
