[0032] Example
[0033] This embodiment provides a waterproof device for use in a flat tunnel exploration and excavation process, such as Figure 1-Figure 4 As shown, the specific structure is as follows.
[0034] Combination Figure 1 As shown, the waterproof device used in the flat hole exploration and excavation process of this embodiment mainly includes a scaffolding 1, a moving wheel 3 and a rolling shutter assembly 5, wherein the scaffolding 1 is welded by four ribbed steel bars with a diameter of 12 mm to form a horizontal rectangular base frame with a length of about 2.0 m and a width of 1.8 m, and then four vertical steel bars with a diameter of 12 mm and a height of about 1.6 m are welded at the four corners of the base frame, and a transverse steel bar is welded between the two vertical steel bars on the side for reinforcement. The arched top 2 is composed of two arched steel bars at the front and rear ends, and the arched steel bars and the vertical steel bars are welded and fixed, and multiple transverse steel bars are welded between the two arched steel bars for reinforcement. Support beams 201 are welded at both ends of the arched top 2, and the support beams 201 and the scaffolding 1 are welded and fixed.
[0035] It should be noted that mobile wheels 3 are installed at the four corners of the bottom of the scaffold 1. The mobile wheels 3 are universal wheels with brakes in the prior art, which have the advantage of flexible use. At the same time, vertical reinforcing rods are welded on both sides of the scaffold 1 to increase the overall structural strength and extend the service life.
[0036] Furthermore, the first waterproof layer 4 and the second waterproof layer 6 are both made of waterproof geotextiles in the prior art, and a first waterproof layer 4 is laid from the left side of the scaffolding 1, the arched roof 2 and the right side of the scaffolding 1, and the edge of the first waterproof layer 4 is fixed by iron wire or nylon tie and steel bars of the scaffolding 1. The first waterproof layer 4 on the top blocks water seepage from the top of the tunnel, and the first waterproof layers 4 on both sides block water seepage from the side walls of the tunnel.
[0037] Combination Figure 1 and Figure 2 As shown, the vertical and horizontal fixing frame 7 is composed of three vertical steel bars and three horizontal steel bars. The vertical and horizontal fixing frame 7 is fixed at the end of the scaffolding 1 close to the tunnel face. The end of the scaffolding 1 away from the tunnel face is an empty door, which is convenient for construction workers to enter and exit. The second waterproof layer 6 covers the entire vertical and horizontal fixing frame 7, and the second waterproof layer 6 is connected to the vertical and horizontal fixing frame 7 by iron wire or nylon cable ties. The second waterproof layer 6 blocks the water seepage of the tunnel tunnel face.
[0038] After the second waterproof layer 6 is laid, holes are drilled at corresponding positions of the second waterproof layer 6 according to the positions of the blast holes on the face to form reserved holes 601. The size of the holes is slightly larger than the diameter of the drilling equipment, so that the drill bit and some drilling tools can smoothly pass through the reserved holes 601 for construction.
[0039] Furthermore, the second waterproof layer 6 is provided with a waterproof sheet 603 which can be opened and closed. The waterproof sheet 603 is made of a copper alloy metal sheet. Figure 4 As shown, a knob 602 is fixed on the upper side of the right end surface of the waterproof sheet 603, and the knob 602 penetrates through the second waterproof layer 6 and goes deep into the interior of the scaffold 1. When drilling holes, the knob 602 is rotated to expose the reserved hole 601 for easy drilling. After drilling, the knob 602 is rotated to make the waterproof sheet 603 completely cover the reserved hole 601 to prevent water from spraying from the reserved hole 601, thereby further improving the waterproof effect.
[0040] In some implementations of this embodiment, Figure 2 As shown, the vertical and horizontal fixing frame 7 is installed with a rolling curtain assembly 5 for blocking water at the top of the outer side, combined with Figure 3As shown, the rolling shutter assembly 5 comprises six parts: a winding drum 507, a rotating shaft 502, a driving chain plate 503, a lifting zipper 504, a guide baffle 505 and a counterweight rod 506. The winding drum 507 is cylindrical, one end of the waterproof rolling shutter 501 is fixed in the winding drum 507, the rotating shaft 502 passes through the middle of the winding drum 507 and the middle of the driving chain plate 503, and the winding drum 507 and the driving chain plate 503 are fixedly connected to the rotating shaft 502. Bearing seats are installed at both ends of the rotating shaft 502, and the bearing seats are welded to the longitudinal and transverse fixing frames 7. The driving chain plate 503 is covered with a lifting zipper 504, and the lifting zipper 504 passes through the second waterproof layer 6 and is located on the scaffold 1, which is convenient for the operator to pull, thereby lifting and lowering the waterproof rolling shutter 501.
[0041] Furthermore, guide baffles 505 are provided on both sides of the winding drum 507. The guide baffles 505 are truncated cone-shaped. The end of the guide baffle 505 with a smaller diameter is butted against the end of the winding drum 507. The guide baffle 505 has an outwardly inclined slope. Due to the tunnel restrictions of the flat hole exploration and excavation, the scaffold 1 has an arched top 2. In order to cover the reserved hole 601 near the arched top 2, the upper winding drum 507 must be shorter and the waterproof roller curtain 501 must be wider. When rolling up, the waterproof roller curtain 501 can be completely wound on the winding drum 507 by relying on the inclined surface of the guide baffle 505, which has a better use effect.
[0042] In order to smoothly raise and lower the waterproof curtain 501, an arched counterweight rod 506 is installed at the bottom of the waterproof curtain 501. The arched counterweight rod 506 prevents the waterproof curtain 501 from blocking the reserved hole 601 at the top when it is retracted, so as not to affect normal construction. The operator constructs the borehole from top to bottom through the reserved hole 601. After the borehole at the same elevation is completed, the waterproof curtain 501 is pulled down to the top of the next elevation borehole, effectively preventing water from shooting from the face.
[0043] The working principle of the waterproof device used in the horizontal tunnel exploration and excavation process of the utility model is as follows:
[0044] The waterproof device used in the horizontal tunnel exploration and excavation process is rolled to the horizontal tunnel section with large water seepage, and then the lower moving wheel 3 is braked to prevent the device from moving. Then, the construction preparations for electrical equipment, drainage equipment, etc. are completed, and the waterproof effects of the first waterproof layer 4 and the second waterproof layer 6 are checked. The waterproof device used in the horizontal tunnel exploration and excavation process can better intercept water and smoothly drain it to the drainage ditches on both sides to ensure the working environment in the tunnel.
[0045] Then, the waterproof roller curtain 501 on one side of the face is raised, the uppermost waterproof sheet 603 is opened, and the drilling rig implements the uppermost drilling through the reserved hole 601 (drilling from the highest point is conducive to intercepting the upper water volume and effectively reducing the amount of water seepage from the lower part). After the drilling is completed, the knob 602 is rotated in time so that the waterproof sheet 603 closes the reserved hole 601 to prevent the drilling from spraying water into the scaffolding 1. After the drilling of the same elevation is completed, the reserved hole 601 at the elevation is closed, and the lifting zipper 504 is used to lower the waterproof roller curtain 501 to the next drilling position to prevent the face from spraying water into the scaffolding 1. There are two waterproof measures at the face, the first waterproof roller curtain 501 and the second second waterproof layer 6, and the overall waterproof effect is good.
[0046] In summary, the utility model provides a waterproof device for use in the process of flat tunnel exploration and excavation, which includes a scaffold 1, a moving wheel 3 and a rolling curtain assembly 5.

The rolling shutter assembly 5 includes a winding drum 507, a rotating shaft 502, and a driving chain plate 503. The waterproof rolling shutter 501 is connected to the winding drum 507. The winding drum 507 and the driving chain plate 503 are both fixedly sleeved on the rotating shaft 502. The rotating shaft 502 is connected to the longitudinal and transverse fixing frame 7 through a bearing seat. The driving chain plate 503 is connected to a lifting zipper 504. Outwardly inclined guide baffles 505 are arranged on both sides of the winding drum 507. The waterproof rolling shutter 501 is connected to an arched counterweight rod 506.
