Embodiment 1
[0042] Such as figure 1 , figure 2 and Figure 5 As shown, in this embodiment, a dotting device for tunnel waterproofing construction includes a frame body 1 on which several positioning pieces 2 are arranged, and the positioning pieces 2 are used to mark the dotting positions.
[0043] Specifically, the number of the positioning parts 2 is three, and the three positioning parts 2 are arranged in the shape of an isosceles triangle. The structure of the waterproof board in the existing design is a rectangular plate. By setting three positioning parts 2, three The positioning part 2 is surrounded to form an isosceles triangle, and after one dotting, three dotted positions can be formed on the rock wall, and the three dotted positions form an isosceles triangle, and then the frame body 1 is rotated 180° around one of the dotted positions as the base point , carry out the second dotting, and form five dotting positions on the rock wall, and the five dotting positions are mispla...
Embodiment 2
[0049] Such as Figure 1-Figure 5 As shown, in this embodiment, the difference with Embodiment 1 is that a marking pen 3 is respectively provided in each of the positioning holes 21, which is convenient for directly performing a dotting operation at the position of the positioning hole 12 through the marking pen 3, and does not need Temporary search for dotting tools to improve construction efficiency.
[0050] Further, the frame body 1 is provided with moving parts, and the moving parts are used to resist the marker pens 3, and push the three marker pens 3 at the same time through the moving parts, so that the three marker pens 3 can be placed on the rock wall at the same time. Firstly, the construction efficiency is improved, and secondly, compared with the three marking pens 3, it has an advantage in sequentially marking at the same time: in the process of sequentially marking, the frame body 1 held by the construction personnel may be displaced on the rock wall or due to t...
Embodiment 3
[0055] In this embodiment, a tunnel waterproof board construction marking method using a tunnel waterproof board construction marking device as described in Embodiment 1 or 2, the steps include:
[0056] Step 1, install the frame body: place the frame body 1 on the rock wall;
[0057] Step 2, dotting for the first time: perform dotting operation on the positions of the three positioning pieces 2 arranged in an isosceles triangle, and form three dots on the rock wall;
[0058] Step 3, rotating the frame body: rotate the frame body 1 around one of the positioning parts by 180°;
[0059] Step 4, dotting for the second time: perform dotting operation on the positions of the other two positioning parts 2 whose positions have changed, and form five dots on the rock wall.
[0060] The present invention relates to a tunnel waterproof board construction dotting method. Three positioning pieces 2 are arranged on the frame body 1, and the three positioning pieces 2 are surrounded to for...
