[0050] In addition, in order to improve the stability of the needle beam and inverted arch trolley after being assembled on the tunnel construction site, the farthest end of the needle beam base 12 away from the needle beam 11 is provided with a circular arc side surface. The topmost surface and the bottommost surface of the needle beam 11 in the height direction are provided with rails to reduce the friction force when sliding with the beam frame part 20.

[0051] Specifically, as shown in Figure 2 the needle beam transverse moving mechanism 14 comprises a base 141, a translation seat 142 and a first telescopic cylinder 143, wherein the base 141 is fixed on the top end surface of the needle beam base and extends along the width direction of the needle beam 11; one end of the translation seat 142 is slidably fixed with the needle beam base 12 through the base 141, the other end is fixedly arranged with the needle beam 11 in an integrated and co-moving manner; one end of the first telescopic cylinder 143 is fixed on the base 141, and the other end is fixedly arranged with the translation seat 142 in an integrated and co-moving manner.

[0054] Preferably, the steel bar trolley device includes a steel bar lifting trolley and a steel bar installation trolley arranged in front of the steel bar installation trolley, and two layers of push-pull working platforms are arranged on the steel bar trolley.

[0055] In this embodiment, the steel bar trolley device includes a steel bar lifting trolley and a steel bar installation trolley arranged in front of the steel bar installation trolley; the steel bar lifting trolley is used to lift the steel bars in the transport vehicle to the platform on the steel bar lifting trolley, thereby playing a role of transferring and temporarily storing the steel bars; the steel bar installation trolley is a working place for the operator to make, bind and install the steel bars; two layers of push-pull working platforms are arranged on the steel bar trolley, the push-pull structure can greatly save space, the structure of the steel bar trolley is more compact, more working platforms are provided for the steel bar trolley, and the movement of the trolley is not affected.

[0056] More preferably, the steel bar trolley comprises a support frame, a walking part and a steel bar conveying part, wherein the walking part is arranged at the bottom end of the support frame and moves together with the support frame; the steel bar conveying part is fixed on the support frame and is rotatably arranged relative to the support frame; the steel bar conveying part comprises a placing platform, a top platform and a transfer device, the placing platform is horizontally fixed on the support frame and extends along the length direction of the support frame; the top platform is fixed on the placing platform and extends along the length direction of the support frame; the transfer device is arranged between the placing platform and the top platform and is arranged to switch the hoisting of the steel bar between the placing platform and the top platform.

[0057] Preferably, the two-lining trolley comprises a portal assembly, a variable-diameter telescopic assembly, a lining formwork assembly and an extension assembly.

[0058] The lining formwork assembly comprises a plurality of arc-shaped formworks connected in sequence and arranged at the periphery of the portal assembly in a detachable manner.

[0059] The variable-diameter telescopic assembly is arranged between the portal assembly and the lining formwork assembly and drives the lining formwork assembly to increase or decrease in diameter through telescoping.

[0060] The extension assembly is arranged at the gap of the lining formwork assembly when the diameter of the lining formwork assembly is increased.

[0061] The lining formwork assembly is arranged in two groups in a left-right symmetrical manner along the central axis of the lining trolley; at least one pair of arc-shaped formworks among the adjacent arc-shaped formworks are detachably connected; and the extension assembly is detachably arranged between the adjacent arc-shaped formworks.

[0062] In this embodiment, the two-lining trolley is provided with the lining formwork assembly composed of a plurality of arc-shaped formworks, the variable-diameter telescopic assembly and the extension assembly, so that the diameter of the lining trolley can be quickly and adaptively adjusted according to the actual situation of the tunnel under construction, thereby improving the use range. Compared with the traditional way, when the diameter changes, a new synchronous lining trolley needs to be designed and manufactured and transported to the construction site, which greatly improves the construction efficiency and reduces the waste of manpower, financial resources and time.

[0063] Preferably, the portal assembly comprises a portal body, a gantry and a gantry telescopic part.

[0064] The portal body is arranged on the track at the bottom of the tunnel.

[0065] The bench is detachably arranged on the portal body.

[0066] The bench telescoping part is arranged between the bench and the portal body.

[0067] In this embodiment, the portal assembly comprises the portal body and the bench, and the bench telescoping part is arranged between the portal body and the bench. When the diameter of the two-lining trolley is increased or reduced, the portal body at the lower part remains unchanged, and the bench at the upper part is extended or retracted through the bench telescoping part arranged between the portal body and the bench, so that the center of the lining formwork assembly is raised or lowered, so that the overall framework of the portal assembly is adapted to the diameter change of the two-lining trolley, so as to better support and bear other components, and meanwhile, the force angle change caused by the diameter change of the lining formwork assembly is adapted, and the force condition of the entire portal assembly is improved.

[0068] More preferably, the portal assembly further comprises a first adjusting part or / and a second adjusting part.

[0069] The first adjusting part is detachably arranged between the portal body and the bench.

[0070] The second adjusting part is detachably arranged between the bench and the lining formwork assembly.

[0071] In this embodiment, when the telescoping of the variable-diameter telescoping assembly is completed, the lining formwork assembly itself has a large weight, and if the lining formwork assembly is continuously borne by the variable-diameter telescoping assembly for a long time, the telescoping performance of the variable-diameter telescoping assembly will be damaged, and even the variable-diameter telescoping assembly will be damaged, so that the two-lining trolley cannot be used. Therefore, the second adjusting part is arranged at the contact position between the bench and the lining formwork assembly, and the second adjusting part bears the weight of the lining formwork assembly, so that the service life of the two-lining trolley is improved. Meanwhile, the distance adjusted by the second adjusting part is adapted to the diameter change amount of the tunnel variable cross-section, and the telescoping change amount of the variable-diameter telescoping assembly is no longer used to adapt to the diameter change amount of the tunnel variable cross-section, so that the precision of the diameter change is improved.

[0072] Preferably, the split TBM synchronous lining construction device further comprises a belt supporting trolley, a transformer supporting trolley, a continuous belt conveyor, and a drag pump.

[0073] The belt supporting trolley is used to support the continuous belt conveyor, water pipes, cables, and air pipe accessories in the construction process.

[0076] In this embodiment, the separated TBM synchronous lining construction device is additionally provided with a support trolley, a transformer support trolley, a continuous belt conveyor and a trailing pump. Because each trolley is used in a skip work mode and there is a certain distance between the synchronous lining devices, the continuous belt conveyor, water pipes, cables and air pipes arranged between the distances lack support points. Therefore, the belt support trolley is arranged between the synchronous lining devices to eliminate the adverse effects on the power supply, communication, ventilation, water supply and drainage and spoil transportation required for TBM construction. The continuous belt conveyor is responsible for continuously conveying spoil and other construction waste outside the tunnel to meet the needs of construction. The transformer support trolley is used to move the transformer and power distribution cabinet accessories into the tunnel along with the construction progress to ensure stable power supply in the tunnel. More preferably, the transformer support trolley is provided with a transformer damping assembly to reduce the influence of vibration generated during tunnel construction on the electrical equipment of the transformer and power distribution cabinet accessories and improve the stability of power supply of the transformer and power distribution cabinet accessories. The trailing pump is matched with the secondary lining trolley to convey concrete for secondary lining and complete secondary lining pouring. More preferably, the trailing pump is a single-track trailing pump, which can greatly reduce the occupation of the transportation track.

[0077] Preferably, referring to Figure 4 , the separated TBM synchronous lining construction device further comprises a pipeline crossing device.

[0078] In this embodiment, the pipeline crossing device is additionally provided in the separated TBM synchronous lining construction device. During the movement of the needle beam inverted arch trolley, the reinforcement trolley, the secondary lining trolley and the maintenance trolley, the pipeline crossing device is used for pipeline crossing. If the traditional method is used, various fixed supports such as installation brackets are arranged on the tunnel wall to support various pipelines and lines. Because each trolley often needs to move up and down, left and right and forward and backward, the fixed supports and the pipelines arranged on the fixed supports will interfere with the movement of the trolley. At this time, the fixed supports and the pipelines arranged on the fixed supports need to be removed to meet the needs of the trolley moving up and down, left and right and forward and backward. The above-mentioned various situations will greatly waste time, manpower and material resources and also seriously affect the continuity and efficiency of construction. The pipeline crossing device is used for pipeline crossing to avoid interference with the pipelines during the movement of various trolleys and also does not need to dismount the fixed supports such as installation brackets while supporting the pipelines, which improves the continuity and efficiency of construction and greatly saves time, manpower and material resources.

[0079] Specifically, referring to Figure 4 , the pipeline crossing device comprises a walking support 21, a support seat 22 arranged above the walking support 21 and a pipe supporting frame 23.

[0080] The walking support 21 is arranged on the lifting mobile device and moves relative to the mobile device in the vertical direction;

[0081] The pipe supporting frame 23 is arranged above the support base 22 and slides left and right to support the pipeline.

[0082] In this embodiment, a pipeline crossing device is provided, and the pipe supporting frame is used to support the pipeline, so that the pipeline carried on the pipe supporting frame does not affect the movement of the mobile device when the mobile device moves up and down, forward and backward, and left and right. For example, a two-lining trolley is used in tunnel construction, which needs to move up and down, forward and backward, and left and right in the tunnel. The two-lining trolley is used as a mobile device, and the walking support is arranged on the lifting mobile device. The walking support is arranged on the tunnel track, and the pipeline of the tunnel construction is arranged on the pipe supporting frame. 1. When the two-lining trolley needs to move up and down, the walking support moves relative to the mobile device. That is, when the two-lining trolley moves up and down, the two-lining trolley slides up and down relative to the walking support, and the height of the pipeline carried in the pipe supporting frame above remains unchanged. For example, the pipeline crossing device is installed on the lining trolley, the walking support of the pipeline crossing device passes through the sliding hole of the lining trolley portal bottom longitudinal beam, and slides up and down relative to the lining trolley bottom longitudinal beam. At this time, the pipeline carried in the pipe supporting frame does not move. 2. When the two-lining trolley moves forward and backward in the tunnel, the walking support moves forward and backward, and the pipe supporting frame moves forward and backward. The pipe supporting frame moves forward and backward relative to the pipeline, and the pipeline arranged on the pipe supporting frame does not move, and does not interfere with the forward and backward movement of the lining trolley. 3. When the two-lining trolley moves left and right in the tunnel, the walking support moves left and right, and the support base slides left and right relative to the pipe supporting frame. Because the weight of the pipeline is large, and the friction force between the support base and the pipe supporting frame is small, the pipe supporting frame and the pipeline carried on the pipe supporting frame do not move, and do not interfere with the left and right movement of the lining trolley. In summary, the pipeline crossing device supports the pipeline, and avoids affecting the up and down, forward and backward, and left and right movement of the lining trolley. Under the action of the pipeline crossing device, the device for fixing the pipeline does not need to be disassembled during the working process of various trolleys, reduces the wear of the pipeline, improves the engineering quality, and reduces the labor intensity.

[0095] If the traditional way is adopted, various types of fixed supports such as mounting brackets are arranged on the tunnel wall to support various lines. Because various types of trolleys often need to move up and down, left and right, and forward and backward, the fixed supports and the lines arranged on the fixed supports will interfere with the movement of the trolleys. At this time, the fixed supports and the lines arranged on the fixed supports need to be removed to meet the needs of the trolleys moving up and down, left and right, and forward and backward.
