Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments.

Fig. 1 is a schematic structural view of a kneading tool according to an embodiment of the present invention. The core of the application is to provide a processing method of a gap at the bottom of a bridge hollow slab, which comprises the following steps:

s1 preparing treatment materials required by construction, wherein the treatment materials comprise: moving a scaffold, a steel springboard, a steel wire brush, an ink fountain, an iron shovel, wet cloth and a kneading tool;

s3, cleaning exposed mortar and sundries in the adhering range of the gap by using a shovel and a steel wire brush, and wetting and scrubbing dust in the adhering range by using wet cloth;

s4, popping the sticking edge line at the sticking position at the bottom of the board by adopting an ink fountain, sticking a waterproof coiled material glue layer at the sticking position, and cutting the redundant waterproof coiled material glue layer;

s5 kneading processing is performed at the pasting position using a kneading tool.

Specifically, the treatment material required for construction in S1 is prepared, and the treatment material includes: the device comprises a movable scaffold, a steel springboard, a steel wire brush, an ink fountain, an iron shovel, wet cloth and a kneading and pressing tool. Wherein the movable scaffold is used for building a working platform and operating thereon. The use of the steel gangplank enables the steel pipes for building the scaffold to be properly reduced, and the building efficiency can be improved. The steel wire brush and the shovel can clean exposed mortar, sundries, concrete blocks and the like on the pasting surface, so that the pasting surface is cleaner and the pasting effect is better. In order to facilitate later construction, the processing material in S1 further includes scissors, and the waterproof roll glue layer is cut by using the scissors.

Specifically, in S2, the support legs of the movable scaffold are supported and cushioned by wood boards, so that a bridge gap processing working platform is provided; the use of plank can make the removal scaffold frame steady more at the during operation. Further, the erection length of the mobile scaffold in S2 is erected according to the length of the steel ramp.

Specifically, in S3, a shovel or a wire brush is used to clean mortar and foreign matter exposed in the range of the gap, and wet cloth is used to wet and scrub dust in the range of the gap. The area in the pasting range after cleaning is more convenient to paste, and the effect after gap processing is better. Considering the adaptation to the size of the gap, further, the size of the pasting range is 10cm-12 cm. Wherein the size of the pasting range can be 11 cm.

Specifically, at S4, the ink fountain is used to pop the adhering edge line out of the adhering position at the bottom of the board, the glue layer of the waterproof roll is adhered at the adhering position, and the excess glue layer of the waterproof roll is cut. The line type of pasting is more pleasing to the eye, and the position is more accurate after bullet line processing. The efficiency of constructor carrying out gap processing operation is higher. Meanwhile, compared with a concrete mortar treatment mode, the adhesive layer of the adhered waterproof coiled material is more convenient to construct, and working procedures such as construction and maintenance are not needed, so that the construction cost is greatly reduced, and the construction time is saved. In order to achieve better pasting effect, the glue layer of the waterproof roll is a butyl glue layer of the waterproof roll. The butyl waterproof coiled material glue layer is similar to the double faced adhesive tape, the color of the butyl waterproof coiled material glue layer is similar to that of concrete, the butyl waterproof coiled material glue layer is shiny, and the attractiveness of the butyl waterproof coiled material glue layer after being pasted is high. And the adhesive is firmly adhered to the concrete surface.

Specifically, at S5, the kneading process is performed at the pasting position using the kneading tool. The gap treatment effect after kneading and pressing treatment is better, so that the glue layer of the waterproof coiled material is more closely and firmly adhered to the hollow plate. As shown in fig. 1, further, the kneading tool in S5 includes a rubber roller 1, and the rubber roller 1 is mounted on the hand lever 2. The rubber roller 1 is made of rubber material, and is more convenient for kneading operation.
