Description
Technical Field
The invention relates to the technical field of building waterproofing, in particular to a construction method of a coating and rolling composite waterproofing system.
Background
The side wall often has concrete pouring defects such as not being compacted by vibration, cellular pitted surface and the like in the building process, so that the waterproof construction is difficult, and the waterproof effect is influenced.
Its waterproofing membrane to planting the roof needs to have resistant root system puncture function, generally adopts two kinds of modes: one is "chemical root resistance" which prevents the penetration of the root system by adding a root-resistant agent to the material, and the other is "physical root resistance" which prevents the penetration of the root system through the coiled material by the mechanical strength and hardness of the material itself. At present, the root-resisting agent independently researched and developed in China is few, most of the root-resisting agents in the market are imported abroad, the cost is high, the field detection is difficult, and consumers can not know whether effective components are really added in the purchased waterproof coiled material or whether the dosage reaches the standard; meanwhile, the root-resisting agent can be damaged by heating in the construction process and high-temperature stirring in the production process, and the excessive or insufficient dosage of the root-resisting agent can also have adverse effects on the root-resisting performance of the material. The invention achieves the root resistance effect through a physical root resistance mode.
For the construction of a bottom plate waterproof system, the bottom plate of the conventional coiled material is bonded with a cushion layer and is not bonded with a structural layer during the construction, so that the water channeling prevention can not be really realized.
Disclosure of Invention
In order to solve the technical problems, the invention adopts the following technical scheme:
a construction method of a coating and rolling composite waterproof system comprises the following steps:
step a. cleaning the base surface
Step b, preparing waterproof paint
Step c, line snapping and positioning
Step d, paving a waterproof roll
Step e, blade coating of waterproof paint
F, spreading and pasting the waterproof coiled material compositely
Step g, hot air welding of lap joint edges of coiled materials
And h, closing up.
Preferably, the waterproof coating is a cement-based permeable crystallization type waterproof coating or a polyurethane waterproof coating.
Preferably, the step c is: determining the overall paving direction of the coiled material according to the shape of the base surface; starting from 300-600 mm away from the joint of the peripheral flat vertical surfaces or one side of the corner of the base surface, arranging lap joint control lines in parallel so that lap joints avoid the joint of the peripheral flat vertical surfaces or the corner; and taking the lap joint control line as a starting line, and sequentially and outwards paralleling the snapping lines.
Preferably, the step d is: the position of the overlapping edge determines the direction of the coiled material, and the waterproof coiled material is spread; and (3) short edge staggered joint, positioning and cutting the coiled materials according to the position of the elastic thread or the lap joint control line, wherein the staggered length of the short edges of two adjacent coiled materials is not less than 1/3 breadth.
Preferably, the step f further comprises a process of compacting and exhausting the coiled material after the paving is finished.
Preferably, the positions of the internal and external corners, the pile head, the anchor rod and the wall penetrating pipe in the step g are welded with the coiled materials by adopting detail prefabricated parts.
Preferably, the step a further comprises a process of manufacturing a straight circular arc by adopting cement mortar at the joint of the base surface and the protruding structure and the joint of the plane and the vertical surface.
The waterproof materials adopted by the invention are all environment-friendly waterproof materials, and the environmental protection index is higher than the current national standard specification. The cement-based permeable crystallization type waterproof coating can be constructed by spraying or blade coating, has low requirements on the base surface, and can play a role in repairing and leveling the defects of cracks, pitted surfaces, unevenness and the like of the base surface, and meanwhile, the coating has a permeable crystallization function and can self-repair cracks below 0.4 mm. The wet paving method is adopted, the time for waiting for drying the coating is saved, the construction period is greatly shortened, the construction can be carried out particularly in rainy season, and the construction progress is not influenced. When wet paving construction is carried out on the bottom plate, the side wall, the planting top plate and the roof, a sufficient, complete and molecular-level interlocking structure is formed between the liquid flow coating and the glue layer of the high-molecular self-adhesive coiled material, and an abnormal strong occluded adhesion is generated to form a skin type full adhesion, so that pressure water can be effectively prevented from flowing between the coiled material and the main structure concrete, and the water flowing condition is prevented from being generated. During construction, the thin prefabricated parts are used at the penetrating positions of the internal and external corners, the pile heads, the anchor rods, the wall penetrating pipes and the like, labor cost can be greatly saved, material loss caused by field cutting is reduced, and the welding and overlapping strength of the prefabricated parts and the coiled material body is more than three times that of gluing and coating. The invention relates to a waterproof structure for underground waterproof engineering, which is characterized in that the difficulty in underground waterproof engineering is the waterproofing of through joints such as construction joints, expansion joints and the like, in particular to waterproof engineering at joints of a top plate and side walls and between the side walls and a bottom plate.
Meanwhile, the side wall and the coiled material are high in bonding and peeling strength, and the common problem that the side wall is prevented from water falling and slipping in the industry can be eliminated. The physical root resistance is adopted when the method is applied to planting roofs and roofs, and the root resistance is more durable and stable.
