The drainage ditch is very important in the tunnel, and its main function is to drain water and clean up garbage. If the accumulated water, collected water or other sewage in the tunnel cannot be discharged from the tunnel in time, some chemical elements contained in it may corrode the roadbed, shock-absorbing rubber pads and other easily corroded parts. For example, the vibration isolator will lose its shock-absorbing function due to corrosion, which may easily cause driving safety accidents, or if there is too much rainwater overflowing the track, it will bring great safety hazards to driving safety.

[0004] In the prior art, the tunnel track bed drainage ditch template includes two parts: the ditch template and the lifting device. The ditch template can be a wooden template, a steel template, etc., and the lifting device is generally composed of a steel structure. During the construction of the track bed ditch, a transition section is generally provided. The size of the transition section drainage ditch is different from that of the general track bed ditch.

DETAILED DESCRIPTION

[0019] The utility model is further described below with reference to specific embodiments.

[0020] Embodiment 1: A universal integral roadbed ditch center template structure mainly includes a hoisting device 3 and a supporting device 4, and also includes a tunnel 1, a floating plate steel structure mesh, and a drainage ditch template 5.

[0021] The hoisting device 3 comprises a crossbeam 3.1, a clamping plate 3.2, a sliding channel 3.3, a bolt hole 3.4, and a positioning gasket 3.5.

[0022] The supporting device 4 comprises an upper supporting leg 4.1, a lower supporting leg 4.2, a pin rod 4.3, an upper pin hole 4.4, an upper bolt hole 4.5, a lower bolt hole 4.6, and a lower pin hole 4.7.

[0023] like Fig.10 As shown, the cross beam 3.1 is a rectangular channel steel structure without a cover, with convex plates on the upper part of both ends of the cross beam 3.1, and the lower part is dug out to fit the bottom edge of the rail, and bolt holes 3.4 are provided on the bottom plates at both ends of the cross beam 3.1; Fig.23 As shown, the clamping plates 3.2 are placed at the bottom of both ends of the cross beam 3.1, and the cross beam 3.1 is connected to the rails by bolts.

[0024] like Figure 7 As shown, the middle bottom plate of the cross beam 3.1 is provided with a sliding channel 3.3, which is a rectangular structure, passes through the bottom plate of the cross beam 3.1, and has a concave groove at the edge of the sliding channel 3.3. The positioning gasket 3.5 is mainly embedded in the sliding channel 3.3. One type is a detachable gasket, such as Fig.18 As shown, convex plates are provided at both ends of the positioning gasket 3.5 to cooperate with the concave groove provided on the edge of the sliding channel 3.3; its advantage is that the position of the concave groove of the sliding channel 3.3 is determined in advance, and the gasket is directly inserted into it, which not only limits the horizontal movement of the bolt, but also accurately positions the bolt, so that drainage ditch templates 5 of different standards can be hoisted, such as 400mm or 600mm in width or other sizes. Commonly used drainage ditch templates 5 can be applied to different templates by simply adjusting the position of the gasket.

[0025] The support device 4 is connected to the lifting device 3 through bolts and positioning gaskets 3.5. Figure 6As shown, the upper leg 4.1 is in contact with the lower leg 4.2 and is fastened by a pin rod 4.3 to limit their free movement; the upper and lower legs are basically the same, the lower leg 4.2 is slightly larger than the upper leg 4.1, and the sides of the upper and lower legs are provided with several pin holes, which are mainly used to adjust the leg height and stabilize the leg structure; the upper and lower legs are both L-shaped structures, and the bottom (upper part) is provided with a rectangular thin plate fixedly connected to the side L plate, and a bolt hole is provided in the center of the rectangular thin plate; the upper leg 4.1 is connected to the positioning gasket 3.5 by bolts, and the lower leg 4.2 is connected to the drainage ditch template 5 by bolts.

[0026] The legs are configured as L-shaped plates with a plurality of pin holes on both sides. The pin rods 4.3 are horizontally inserted into the pin holes on both sides of the L-shaped plates. The design of the L-shaped plates can save material costs, and the insertion of the pin rods 4.3 can also enhance the stability of the support device 4.

[0027] Preferably, the pin 4.3 may also be 7-shaped, T-shaped, or other rod-shaped structures, with the head slightly protruding, or the protruding portion being embedded in the pin hole, so that the pin can be more stably inserted into the leg.

[0028] Embodiment 2: Based on the technical solution of embodiment 1, preferably, another non-detachable gasket such as Fig.26 As shown, grooves are provided at both ends of the positioning gasket 3.5 to adapt to the improved sliding channel 3.3. The improved sliding channel 3.3 is provided with a convex plate in the channel to allow the positioning gasket 3.5 to slide in the channel and limit the vertical movement of the positioning gasket 3.5. The advantage is that the scale of the sliding channel 3.3 is more precise, and the positioning gasket 3.5 can be applied to a larger range of more irregular drainage ditch templates 4.

[0029] Embodiment 3: A method for using a universal integral roadbed ditch center template.

[0030] First, the track 2 is fixed at the center position in the tunnel 1 using an existing support device, and a bundled steel mesh is set at the bottom of the tunnel 1.

[0031] Secondly, place the gutter template 5 at the center of the track 2, place the crossbeam 3.1, place three to four crossbeams 3.1 for each section of rail, and fasten them with clamps 3.2.

[0032] Next, place the positioning gasket 3.5 at the designated position, that is, the distance suitable for the width of the gutter template 5, and then use bolts to connect the upper leg 4.1 to the beam 3.1; the lower leg 4.2 is connected to the rectangular hole on the gutter template 5 by bolts, adjust the height of the gutter template 5, and use the pin rod 4.3 to insert it into the pin holes of the upper and lower legs to tighten the gutter mold.

[0033] Finally, concrete is poured into the base of the tunnel 1 to cast the ballast bed. Due to the obstruction of the drainage ditch template 5, a rectangular trough-shaped drainage ditch will be formed in the center of the ballast bed 1.1. By adjusting the height of the supporting device, a drainage ditch with a certain inclination angle can be obtained to facilitate drainage of the tunnel.

[0034] During disassembly, first remove the fastening of the cross beam 3.1, then remove the connection between the cross beam 3.1 and the upper leg (4.1), pull out the pin 4.3, then remove the connection between the lower leg 4.2 and the gutter template 5, and finally remove the gutter template 5. After the disassembly operation is completed, the next operation position can be moved to.

[0035] Embodiment 4:

[0036] like Figure 29-31 As shown, this embodiment is a simple embodiment, and only two types of gutter templates with fixed distances are hoisted, one is a short rail sleeper gutter width of 400mm, and the other is a trapezoidal rail sleeper width of 600mm. Its advantages are: only four fixed bolt holes need to be set in the middle of the beam, the inner two correspond to the 400mm gutter template, and the outer two correspond to the 600mm gutter template. The lower part is provided with adjustable legs, which is consistent with the leg setting in the above embodiment. The advantage of this method is that the design is simple and convenient, and there is no need to move and adjust the positioning gasket. It only needs to select the appropriate bolt hole for installation, and the installation steps are the same as the above embodiment.

[0037] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
