Description

Technical Field

[0001] The utility model relates to the technical field of tunnel lining trolleys, in particular to a secondary lining and trench integrated lining trolley for tunnels. Background Art

[0002] The tunnel lining trolley is a construction equipment used for tunnel lining. In the construction of some tunnel linings, there is trench construction in the tunnel. The current common practice is to carry out tunnel lining and trench lining separately. This practice has clear processes and the tunnel lining and trench lining do not interfere with each other. However, there are two disadvantages. One is that the construction period is long and the efficiency is low. The tunnel lining and trench lining are constructed separately. The trench lining can only be carried out after the tunnel lining is completed, or the tunnel lining can be carried out after the trench lining. The construction period is long and the efficiency is relatively low. The second is that the equipment cost is high. The tunnel lining and trench lining are constructed separately, which requires two sets of equipment, the lining trolley and the trench trolley, which is costly.

[0003] How to design a tunnel secondary lining and trench integrated lining trolley that is ingenious in conception, easy to operate, simple to use, shortens the tunnel construction period, improves construction efficiency, and reduces construction costs is a problem that needs to be solved at present.

[0007] As a further optimization scheme of the above-mentioned tunnel secondary lining and trench integrated lining trolley, the trench formwork support system includes a trench formwork support frame and a trench formwork support screw, wherein the trench formwork support frame is fixed on the trolley door frame, and the inner large formwork is hung under the trench formwork support frame through a cylinder, and the trench formwork support frame is used to bear the weight of the inner large formwork.

[0008] As a further optimization scheme for the above-mentioned tunnel secondary lining and trench integrated lining trolley, the trench formwork control system includes a trench formwork horizontal displacement cylinder group and a trench formwork vertical displacement cylinder group. One end of the trench formwork horizontal displacement cylinder group is connected to the trolley gantry through a cylinder pin, and the other end is connected to the top of the inner large formwork through a cylinder pin. The position of the inner large formwork in the horizontal direction is adjusted by adjusting the extension length of the piston rod of the trench formwork horizontal displacement cylinder group.

[0027] The working process of this utility model is as follows:

[0028] The primary lining pouring of the tunnel secondary lining and trench integrated lining trolley can be divided into three steps, as follows:

[0029] 1. Set up the mold

[0030] (1) Trolley template stand

[0031] ① Control the trolley travel mechanism 105 to adjust the trolley's front and rear positions so that the trolley template overlaps the inner side of the lined tunnel.

[0032] ② Adjust the trolley lifting and transverse movement mechanism 106 to align the trolley center with the tunnel design center, and to make the center of the trolley top template flush with the tunnel design height.

[0033] ③ Adjust the side mold cylinder of the trolley template so that the trolley side mold reaches the designed position to complete the positioning of the trolley template.

[0034] ④ Install the trolley screw system 104 to form a rigid support between the trolley template system 101 and the trolley gantry 102. The trolley body mold is now completed.

[0035] (2) Trench formwork

[0036] ① Adjust the trench template horizontal displacement cylinder group 20301 so that the horizontal position of the large template 20102 inside the trench meets the design requirements.

[0037] ② Adjust the vertical displacement cylinder group 20302 of the trench template to compact the bottom of the large template 20102 inside the trench with the trench ground to prevent the concrete from falling from the bottom of the trench template and complete the positioning of the trench template.

[0038] ③Install the trench template support screw 20202 to support and fix the two large trench inner templates 20102 to each other.

[0039] ④Install the small template 20101 on the outside of the trench and complete the trench template erection.

[0040] 2. Pouring

[0041] (1) When pouring trench concrete, the trench concrete should be poured first. The two sides should be poured symmetrically, and the height difference of the concrete liquid level on both sides should not be too large.

[0042] (2) Secondary lining concrete pouring: After the trench concrete pouring is completed, the secondary lining concrete pouring can be carried out. There is no pause between the trench concrete pouring and the secondary lining concrete pouring.

[0043] When pouring the secondary lining concrete, it is also necessary to pour it symmetrically on both sides, and the height difference of the concrete liquid level on both sides must not be too large until the pouring of the trolley arch is completed.

[0044] 3. Demolding

[0045] After the trolley lining is poured, the demoulding can be carried out when the concrete reaches a certain strength. The demoulding sequence is to first demould the trench formwork, and then demould the trolley formwork. The implementation method is as follows:

[0046] (1) Demolding of trench formwork

[0047] ①Remove the small template 20101 on the outside of the trench.

[0048] ②Remove the trench formwork supporting screw 20202.

[0049] ③ Operate the trench template horizontal displacement cylinder group 20301 to make the large template 20102 inside the trench move horizontally toward the center line of the tunnel, so that the trench template is separated from the trench wall.

[0050] ④ Operate the vertical displacement cylinder group 20302 of the trench template to make the large template 20102 inside the trench leave the ground and maintain a certain height above the ground, thereby completing the demoulding work of the trench template.

[0051] (2) Demolding of the trolley template

[0052] ① Remove the trolley screw system 104.

[0053] ② Contract the trolley template side form oil cylinder 101 to separate the trolley side form from the tunnel side wall and keep a certain distance from the side wall.

[0054] ③ Adjust the trolley lifting and transverse movement mechanism lifting cylinder 106 to lower the height of the trolley and complete the demoulding work of the trolley template.
