Surface treatment: According to the part where the cracks are located, cement mortar, waterproof quick-setting mortar and epoxy mortar can be used to coat the surface of the cracked part, adhesive patch, inlay and spray slurry repair.

1. Surface treatment: according to the part where the cracks are located, cement mortar, waterproof quick-setting mortar and epoxy mortar can be used to paint, glue, embedded and spray grout to repair the surface of the cracked part.

2. Internal treatment: for shallow cracks and only need to prevent seepage and leakage cracks, generally available cement grouting, such as for the openness of less than 0.3mm or infiltration flow rate is large and affected by the temperature change of the cracks, should be used for chemical grouting.

3. Structural treatment combined with surface treatment: for cracks affecting the integrity of the building or destroying the structural strength, in addition to internal treatment, some still need to take structural treatment combined with surface treatment measures to achieve seepage control, structural reinforcement or restore the integrity of the requirements.

4. The treatment of seepage around: should be mapped out on both sides of the building of the geological situation and seepage of the parts, take appropriate measures to deal with. The method of treatment, excavation and backfill, drilling and grouting and deepening the tooth wall.

5 water, structural joints leakage treatment: concrete building water, structural joints leakage repair, first consider the use of hot asphalt for filling. When filling asphalt is difficult or ineffective, then chemical grouting can be used. Grouting materials available polyurethane, in the use of single-liquid method of grouting, simple equipment, construction is easy. In addition, slurry is often used.

The role of through-wall screw is mainly to fix the template, so that the strength and steel of the template to improve, not to expand the mold. Shear wall penetrating screw has two kinds of cases: one is the basement shear wall with water-stopping penetrating screw; to be removed after the template, the water-stopping screw to protect the water-stopping iron piece of the plastic flared head removed, and then cut the screw at both ends of the tensile screw, with waterproofing mortar to make up for the flat, generally more than the concrete shear wall protrudes from the 5-8MM; the second case is used for the floor of shear walls in a plastic casing in the penetration of the screw, to be removed after the template will be extracted, for the upper turnover use, exterior walls or walls with waterproofing requirements for the wall of penetration of the screw. After the removal of the screw will be withdrawn for the turnover of the upper floor, the screw hole in the external wall or wall with waterproofing requirements must be removed with an electric drill to remove the plastic casing, and then block one side with a wooden wedge to avoid leakage, smoothed with micro-expansion concrete or waterproof mortar, or filled with special foam, and then the wooden wedge is withdrawn to make up for the leveling.

Why new trocars can be removed and reused more than 100 times

First of all, the new casing adopts a conical design (commonly known as the size of the head), in the process of concrete pouring, due to the role of the heat of hydration of the cement, the temperature of the concrete will rise to 40 degrees C ~ 60 degrees C, under the action of the temperature, the casing will be slightly expanded to a larger size, and when the temperature is lowered, the casing will be slightly reduced. When demolding, the actual casing is separated from the concrete, and the conical shape surface makes it easy to remove the casing from the concrete.
