Description

Technical Field

[0001] The invention relates to the technical field of tunnel engineering, and in particular to a device for constructing a central ditch of a tunnel engineering. Background Art

[0002] A tunnel is a structure built underground or underwater or in a mountain to lay a railway or build a road for motor vehicles to pass through. During the tunnel construction process, the central ditch, as the main drainage structure facility, plays an important role in its construction.

[0003] At present, the existing template installation and disassembly of the central ditch of the construction is relatively laborious, the template is very easy to deform, seriously damaged, and has poor flexibility. Therefore, we propose a device for the construction of the central ditch of the tunnel engineering. Summary of the invention

[0004] In order to solve the above technical problems, the present invention proposes a device for constructing a central ditch in a tunnel engineering.

[0005] The technical solution of the present invention is achieved in this way:

[0006] A device for constructing a central ditch in a tunnel project comprises side plates for supporting two side wall templates of the tunnel ditch, a bottom plate connected between the bottoms of the two side plates, and an adjustment component connected between opposite surfaces of the two side plates, wherein the adjustment component is used to control the synchronous relative movement or opposite movement of the two side plates.

[0007] Furthermore, the bottom plate and the side plates are detachably connected via bolts.

[0008] Furthermore, the adjustment assembly includes a middle adjustment component connected between the middle positions of the opposite surfaces of the two side panels and a lateral adjustment component located on the lateral side of the middle adjustment component in the length direction of the side panel, the middle adjustment component includes a middle thread sleeve and a middle screw rod threadedly connected to both ends of the middle thread sleeve, the lateral adjustment component includes a lateral thread sleeve and a lateral screw rod threadedly connected to both ends of the lateral thread sleeve, and the middle screw rod and the lateral screw rod are both connected to the side panel at one end facing the side panel.

[0009] Furthermore, the outer end of the middle screw rod is rotatably connected to the middle connecting seat, and the outer end of the lateral screw rod is rotatably connected to the lateral connecting seat. The middle connecting seat and the lateral connecting seat are both fixed on the side plate, and the middle screw rod and the lateral connecting seat are rotatably connected on the vertical plane.

[0012] Furthermore, a slot entrance for the slide bar to enter the strip slot is provided on an inner side of the top end of the strip slot.

[0013] Furthermore, the width of the strip groove is greater than the outer diameter of the slide bar, so that the slide bar can be displaced in the strip groove along the height direction.

[0014] Furthermore, a baffle plate capable of being inserted into the strip-shaped groove is disposed on the top of the lateral connecting seat, and the distance between the baffle plate and the inner wall surface of the outer side of the strip-shaped groove is adapted to the outer diameter of the sliding rod.

[0015] Furthermore, the middle silk sleeve and the lateral silk sleeve are both provided with through holes.

[0016] The present invention has the following beneficial effects:

[0017] The present invention can not only fine-tune the width of the top opening between the two side panels by adjusting the components, but also shrink the entire device during the construction process, and can lift the device as a whole, reducing the workload of disassembly.

[0019] Figure 2 is a schematic diagram of a second embodiment of the present invention;

[0020] Figure 3 The present invention Figure 2 Enlarged view of point A in . DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1As shown, a typical embodiment of the present invention provides a device for constructing a central drainage ditch in a tunnel engineering, including a side plate 1 for supporting two side wall templates of the tunnel ditch, a bottom plate 2 connected between the bottoms of the two side plates 1, and an adjustment component connected between the opposite surfaces of the two side plates 1, wherein the adjustment component is used to control the synchronous relative movement or opposite movement of the two side plates 1.

[0023] The two side panels 1 are supported on the side surfaces of the two side wall templates of the tunnel ditch, and the two side panels 1 are connected by the bottom plate 2, so that a relatively stable state is formed between the two side panels 1 and the bottom plate 2, which can improve the stability of the side wall template supporting the tunnel ditch. By setting an adjustment component, when the adjustment component causes the two side panels 1 to move away from each other, the template can be fixed to the tied steel bars through the side panels 1, and at the same time, the deviation of the template during the concrete process can be reduced. When the adjustment component causes the two side panels 1 to move relative to each other, the pressure on the template can be removed, which is better adapted to the demolding operation.

[0024] On this basis, the bottom plate 2 is detachably connected to the side plate 1 by bolts. When the device is taken out, if the whole device cannot be taken out directly, the bolts between the bottom plate 2 and the side plate 1 can be removed, and then the bottom plate 2 and the side plate 1 can be taken out in blocks.

[0025] The adjustment assembly includes a middle adjustment component 3 connected between the middle positions of the opposite surfaces of the two side panels 1 and a lateral adjustment component 4 located on the lateral side of the middle adjustment component 3 in the length direction of the side panel 1. The middle adjustment component 3 includes a middle threaded sleeve 3.1 and a middle screw rod 3.2 threadedly connected to both ends of the middle threaded sleeve 3.1. The lateral adjustment component 4 includes a lateral threaded sleeve 4.1 and a lateral screw rod 4.2 threadedly connected to both ends of the lateral threaded sleeve 4.1. The middle screw rod 3.2 and the lateral screw rod 4.2 are both connected to the side panel 1 at one end thereof facing the side panel 1.

[0026] By rotating the middle thread sleeve 3.1 and the lateral thread sleeve 4.1, the size of the opening between the two side plates 1 is adjusted by using the two middle threaded rods 3.2 and the two lateral threaded rods 4.2, so that the two side plates 1 press the template or loosen the template.

[0027] On this basis, the outer end of the middle screw rod 3.2 is rotatably connected to the middle connection seat 5, and the outer end of the lateral screw rod 4.2 is rotatably connected to the lateral connection seat 6. The middle connection seat 5 and the lateral connection seat 6 are both fixed on the side plate 1, and the middle screw rod 3.2 and the lateral connection seat 6 are rotatably connected on the vertical plane, and the lateral screw rod 4.2 and the lateral connection seat 6 are rotatably connected on the vertical plane. During the rotation of the middle thread sleeve 3.1 and the lateral thread sleeve 4.1, the middle connection and the lateral connection seat 6 can respectively prevent the middle screw rod 3.2 and the lateral screw rod 4.2 from rotating.

[0028] like Figure 2 and Figure 3As shown, in a typical embodiment 2 of the present invention, a strip groove 7 is provided on the lateral connection seat 6, and a slide bar 8 is provided on the lateral screw rod 4.2 to move in the strip groove 7. In this embodiment, the slide bar 8 provides pressure to the template by abutting against the inner wall surface of the strip groove 7 close to the template, thereby playing a role in fixing the template.

[0029] When the middle adjustment component 3 is operated to increase the distance between the two side panels 1, the slide bar 8 moves inward relative to the strip groove 7, so that the lateral adjustment component 4 can maintain the same length as a whole, satisfying the process of increasing the distance between the two side panels 1. Therefore, in the actual operation process, it is not necessary to operate the middle adjustment component 3 and the lateral adjustment component 4 simultaneously. It is only necessary to operate the lateral adjustment component 4 after the middle adjustment component 3 has completed increasing the distance between the two side panels 1, and then operate the lateral adjustment component 4 so that the slide bar 8 abuts against the inner wall surface of the strip groove 7 close to the template.

[0030] On this basis, a slot entrance 9 for the slide bar 8 to enter the strip slot 7 is provided on the inner side of the top of the strip slot 7. The slot entrance 9 is used for the slide bar 8 to be pulled out of the strip slot 7, thereby realizing the function of removing the lateral adjustment component 4.

[0031] The width of the strip groove 7 is greater than the outer diameter of the slide bar 8, so that the slide bar 8 can move in the height direction in the strip groove 7. In this way, when the middle adjustment component 3 is operated alone to expand the distance between the diameters of the two side panels 1, the strip groove 7 can move relative to the slide bar 8 in the height direction, and combined with the movement in the inner and outer directions, it is avoided that the limitation of the slide bar 8 on the strip groove 7 affects the movement of the side panels 1.

[0032] On this basis, a baffle 10 capable of being inserted into the strip groove 7 is provided on the top of the lateral connection seat 6, and the distance between the baffle 10 and the inner wall surface of the outer side of the strip groove 7 is adapted to the outer diameter of the slide bar 8. Specifically, after the distance between the two side plates 1 is enlarged by the middle adjustment component 3, and the lateral adjustment component 4 is operated to make the slide bar 8 abut against the inner wall of the strip groove 7 close to the template, the baffle 10 is pushed down so that the baffle 10 abuts against the side of the slide bar 8 away from the template. At this time, the baffle 10 cooperates with the inner wall surface of the strip groove 7 close to the template to achieve the clamping effect on the slide bar 8, so that the slide bar 8 can simultaneously limit the template in the inner and outer directions, thereby reducing the vibration offset of the template during concrete pouring and improving the template stability.

[0033] The middle silk sleeve 3.1 and the lateral silk sleeve 4.1 are both provided with perforations 11. The perforations 11 are used to insert steel bars or iron rods in the operation of the middle adjustment component 3 and the lateral adjustment component 4, so as to increase the lever arm and make the rotation of the middle silk sleeve 3.1 and the lateral silk sleeve 4.1 more convenient.

[0034] Specifically, in the second embodiment, the stopper is arranged in an arc-shaped structure, and a receiving groove is opened on the lateral connecting seat 6. The stopper is rotated into the receiving groove so that it leaves the groove cavity of the strip groove 7, and the stopper is rotated into the inside of the strip groove 7, and can finally be mounted on the side surface of the slide rod 8 away from the template.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
