FIG. 3 is a second schematic view showing the fixing of the waterproof board in the mounting method of the present invention.

detailed description

As shown in FIG. 1 , a tunnel wide waterproof board installation platform includes a mounting bracket, and a walking wheel 8 is disposed at a bottom of the mounting bracket, and a front laying rail 1 and a rear laying rail 2 are disposed on the mounting bracket, and the front laying rail 1 is provided. Mounted on the front end of the mounting bracket 7, the rear laying rail 2 is mounted on the rear end of the mounting bracket 7, and the front laying rail 1 has a front laying trolley 3, and the rear laying rail 2 has a rear laying trolley 4.

The front laying trolley 3 and the rear laying trolley 4 are each provided with support seats 5 and 6, and a reel 11 in which a roll waterproofing plate is placed is installed between the support base 5 on the front laying trolley 3 and the support seat 6 on the rear laying trolley 4. The reel 11 is driven by a driving device to rotate and unwind the waterproof panel 12. The driving device of the reel 11 may be a motor, and the rotating shaft of the motor is connected to the reel 11, and the rotation of the rotating shaft of the motor drives the reel 11 to rotate.

The driving device of the front laying trolley 3, the rear laying trolley 4 and the driving reel 11 of the invention is controlled by a control system, and can control the speed of walking, stopping, walking, etc. of the front laying trolley 3 and the rear laying trolley 4, and can control the reel 11 drive device, thus controlling The reel 11 is rotated at a speed to finally control the unwinding speed of the waterproof panel 12. When the driving device of the reel 11 employs a motor, the rotation speed of the reel 11 can be controlled by controlling the rotation speed of the motor.

A plurality of jacking rods 9 are disposed between the front laying rail 3 and the rear laying rail 4, and the jacking rods 9 are evenly arranged along the arching rails, and both ends of each jacking rod 9 pass through the jacking device 10 Mounted on the mounting bracket 7, the unfolded waterproof panel 12 is laid on the jacking rod 9, the jacking device 10 lifts the jacking rod 9, and the waterproof panel 12 laid on the jacking rod 9 is lifted up close to the tunnel contour surface. The position of the lifting lever 9 may correspond to or does not correspond to the mounting point position of the waterproof panel 12.

The jacking device 10 is uniform in the shape of a tunnel (approximately circular, identical to the laying track), and the position angle of the jacking device 10 is directly opposite the corresponding tunnel contour surface.

The front laying car 3, the rear laying car 4 walking with the reel 11, the waterproof board 12 unfolded on the reel 11 is laid on the jacking rod 9, and the jacking device 10 lifts the jacking rod 9 and lays on the jacking rod 9. The waterproof panel 12 is raised close to the tunnel contour surface. The jacking device 10 is a lifting mechanism such as a hydraulic cylinder, and is not limited herein.

Often, the initial support contour surface of the tunnel is uneven, because the tunnel contour surface is uneven, and the waterproof panel 12 is a flat whole, so that the tunnel contour surface of the recessed portion is difficult to contact with the waterproof panel 12, so it is difficult to ensure the waterproof panel 12 Fixed positioning with the contour of the tunnel. In order to solve this problem, the jacking rod 9 is provided with a soft lifting head 13 which is a jacking head made of a soft material and has a soft texture and a certain stretchability, such as a silicone material. The soft top lifting head 13 is located on the surface of the jacking rod 9, and the soft body lifting head 13 is in contact with the waterproof board 12 to form a point contact.

When the waterproof board 12 is raised, the tunnel contour surface at the protruding portion: the soft top lifting head 13 is between the lifting rod 9 and the waterproof board 12, and the soft top lifting head 13 is pressed by the lifting rod 9 and the waterproof board 12 The deformed state supports the waterproof board 12.

The tunnel contour surface at the recessed portion: since the upper portion of the waterproof panel 12 is a recessed portion, there is no supporting force, and at this time, the force of the jacking rod 9 of the soft lifting head 13 is transferred to the waterproof panel 12 Above, the waterproof board 12 of this part is attached to the tunnel contour surface of the recessed part.

The soft lifting head 13 can be specifically annular, so that it can be directly sleeved on the lifting rod, and the position of the soft lifting head 13 can be adjusted according to the specific concave portion of the tunnel contour surface. It can also be distributed in a grid pattern on the jacking bar.

The jacking devices 10 at each end of each jacking rod are a group, and each group of jacking devices 10 individually controls or synchronously controls the jacking, or individually controls and synchronously controls the jacking together. That is, the control system can synchronously control each group of jacking devices 10 as needed, and send a jacking signal to cause the jacking up; or each group of jacking devices 10 can be individually controlled as needed. The jacking signal is sent to raise the single-group jacking device 10, which can realize the arbitrariness of the jacking surface shape, meet the irregularity of the initial support contour of the tunnel, and achieve close contact with the initial support contour of the tunnel. A separate control for the jacking device 10 can be combined with the above-described soft jacking head 13 for reasonable handling of the tunnel profile with larger recessed portions.

The various solutions described above are applicable to the following two installation methods.

The method for installing the waterproof board 12 of the above-mentioned tunnel wide waterproof board 12 mounting platform comprises the following steps:
