Description

Technical Field

[0001] This utility model relates to the field of civil engineering, and in particular to a tunnel reverse slope drainage and water interception device. Background Technology

[0002] During tunnel reverse slope drainage construction, especially in water-rich sections, the direction of advancement into the tunnel is downhill, and water inside the tunnel converges towards the working face. Timely pumping is necessary to prevent water from accumulating too deeply at the working face, which could affect the stability of the surrounding rock, endanger the safety of the tunnel construction machinery and personnel, and disrupt normal construction production. The reverse slope drainage method inside the main tunnel involves arranging pipelines and drainage pumping stations according to the slope, water volume, and equipment conditions, and discharging water out of the tunnel in stages. Before the water ditch and cable trench are poured, the side ditch serves as a drainage channel. Water from the drainage hole flows towards the tunnel face through the side ditch. If there is no sealing or timely pumping, the water will converge at the end of the invert arch, affecting normal tunnel construction and production, and posing a significant safety hazard. Existing sealing methods mostly involve binding steel bars and pouring concrete foundations to block the water flow. However, this method is troublesome to remove later, requiring excavators, pneumatic drills, and other engineering machinery for demolition, which consumes a lot of manpower and resources. Furthermore, binding steel bars and pouring concrete is time-consuming and labor-intensive, affecting construction costs. Therefore, this application proposes a tunnel reverse slope drainage and water interception device. Utility Model Content

[0003] The purpose of this utility model is to address the problems in the background technology, which make subsequent demolition troublesome, requiring engineering machinery such as excavators and pneumatic picks to break up the foundation, consuming a lot of manpower and material resources, and the time-consuming and labor-intensive process of tying steel bars and pouring concrete, thus affecting construction costs. The present invention proposes a tunnel reverse slope drainage and water interception device.

[0004] The technical solution of this utility model is: a tunnel reverse slope drainage and water interception device, including a template and an extension mechanism disposed on one side of the outer wall of the template;

[0005] The extension mechanism includes a through-hole 1 opened on one side of two templates, a limit rod slidably connected to the inner wall of the multiple through-holes 1, and an extension plate passing through the outer wall of the limit rod, and a fixing mechanism provided on the outer wall of the multiple extension plates;

[0006] The fixing mechanism includes a fixing frame fixed to the outer wall of the extension plate. Multiple connecting columns are fixedly connected to the outer wall of the fixing frame, and a cone head is fixedly connected to the end of the multiple connecting columns away from the fixing frame.

[0007] Optionally, one end of each limiting rod passes through a limiting seat, and the limiting seat is fixedly connected to one side of the template. The other end of each limiting rod passes through an extension plate via a through-hole.

[0008] Optionally, a checkered steel plate is fixedly connected to one side of the outer wall of the extension plate. The checkered steel plate is six millimeters thick and has checkered protrusions on its surface.

[0009] Optionally, a plurality of threaded steel bars are fixedly connected to one side of the template, and the plurality of threaded steel bars have a diameter of 20 mm.

[0013] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] This device, using templates and grating steel plates, enhances the connection of concrete during pouring on the outer wall of the template. The spacing between templates is adjusted by sliding threaded steel bars within sliding steel pipes to accommodate different slopes. Furthermore, by moving extension plates, the template shape can be adjusted to suit varying slope angles and different dimensions. The device is simple to operate, ready to use immediately without additional tools, reducing the difficulty of water interception in slope tunnel side ditches. The removal of templates and concrete is extremely convenient and quick, eliminating the need for manual rebar tying before concrete pouring, saving manpower and resources. The device is reusable, produces aesthetically pleasing concrete, and is more reliable. Attached Figure Description

[0026] Example 1

[0027] like Figures 1-4 As shown, the present invention proposes a tunnel reverse slope drainage and water interception device, which includes a template 1 and an extension mechanism set on one side of the outer wall of the template 1. The extension mechanism includes a through-hole 2 opened on one side of the two templates 1. The inner walls of the multiple through-holes 2 are slidably connected to limit rods 3, and the outer walls of the limit rods 3 are penetrated by extension plates 6. The outer walls of the multiple extension plates 6 are provided with fixing mechanisms.

[0028] With the above settings, by setting the through-hole 2 and the limiting rod 3, the extension plate 6 can be limited to slide, and according to the extension plate 6, the device can adjust the template 1 according to different anti-ditch dimensions, so that the template 1 can achieve a better anti-ditch sealing effect.

[0029] The fixing mechanism includes a fixing frame 8 fixed to the outer wall of the extension plate 6. Multiple connecting posts 9 are fixedly connected to the outer wall of the fixing frame 8. A cone head 10 is fixedly connected to the end of the multiple connecting posts 9 away from the fixing frame 8.

[0030] With the above setup, the fixing frame 8 is used to fix multiple connecting columns 9, and multiple cones 10 are used to fix the entire template 1 in the trench to prevent collapse during concrete pouring.

[0031] In this embodiment, the extension plate 6, which slides along the outer wall of the template 1, allows the template 1 to adjust its shape according to different sizes of reverse slopes, thus adapting to different reverse slope angles.

[0032] Example 2

[0033] like Figure 1 - Figure 4 As shown, based on embodiment 1, one end of each limiting rod 3 passes through a limiting seat 4, and the limiting seat 4 is fixedly connected to one side of the template 1. The other end of the multiple limiting rods 3 passes through an extension plate 6 through a through-hole 5. By setting the limiting seat 4, the limiting rod 3 can slide within the limiting seat 4 when it slides.

[0034] like Figure 1 As shown, a grating steel plate 7 is fixedly connected to one side of the outer wall of the extension plate 6. The grating steel plate 7 is six millimeters thick and has grating-like protrusions on its surface. By setting multiple grating steel plates 7, the connection of the concrete to the outer wall of the template 1 is stronger when concrete is poured, and the concrete will not fall off.

[0035] like Figure 4As shown, multiple threaded steel bars 11 are fixedly connected to one side of the template 1 on one side. The diameter of the multiple threaded steel bars 11 is 20 mm. The multiple threaded steel bars 11 are set so that the templates 1 can be connected to each other.

[0036] like Figure 4 As shown, multiple sliding steel pipes 12 are fixedly connected to one side of the template 1 on the other side. The inner diameter of the multiple sliding steel pipes 12 is 20 mm. By setting multiple sliding steel pipes 12, multiple connecting threaded steel bars 11 can be gathered into the sliding steel pipes 12.

[0037] like Figure 4 As shown, the lengths of the multiple sliding steel pipes 12 and the connecting threaded steel bars 11 are all ten centimeters, and the multiple sliding steel pipes 12 and the connecting threaded steel bars 11 correspond to each other. By sliding the connecting threaded steel bars 11 inside the sliding steel pipes 12, the spacing between the templates 1 is adjusted to adapt to different reverse slopes.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, there are four limit seats 4, and all limit seats 4 are located between multiple sliding steel pipes 12 and connecting threaded steel bars 11, so that the limit rod 3 does not interfere with each other with the multiple sliding steel pipes 12 and connecting threaded steel bars 11.

[0039] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
