Description

[0002] In the construction of a foundation pit, waterproofing is a crucial link, which is directly related to the safety of the subsequent use of the foundation pit and the stability of surrounding buildings. In the waterproofing construction of the outer wall of the foundation pit, due to the high height of the outer wall and the narrow foundation of the outer wall, one person needs to stand on the top of the outer wall and hold a spray gun to burn the waterproofing roll during construction, and the worker at the bottom of the foundation pit needs to cooperate with the worker above to fold the waterproofing roll according to the set width, hold the spray gun to burn, and fix the waterproofing roll on the outer wall of the foundation pit with an extrusion roller. During the construction process, the gas cylinder also needs to be moved, and the whole construction process is very inconvenient. The laying quality of the waterproofing roll depends on the adhesion of the roll to the base, and manual operation of the spray gun and the extrusion roller is adopted. On the one hand, manual operation cannot guarantee that the distance and angle between the spray gun and the roll are always the same, which may cause uneven local heating of the roll, affect the adhesion of the roll to the base, and further cause leakage hazards. On the other hand, the worker has a high labor intensity and low efficiency for a long time of holding the spray gun, and in the complex construction environment of the foundation pit, the worker is not convenient to move, and there is a certain safety risk.
