Rigid and flexible waterproof casing installation process diagram and frequently asked questions.

1 . Get the project pre-work in: in the pre-installation of steel flexible waterproofing casing, construction workman and project manager should clearly manage the decision and purchase to avoid incorrect production and manufacturing, to avoid leakage, through careful checking, the full details of the steel flexible waterproofing casing listed, including the total number of steel flexible waterproofing casing, specification models and installation components. 2 . Get a good variety of data information measurement: generally used to measure the equipment and facilities related to the verification of the department, otherwise it can not be used for the measurement of engineering and construction. In order to better measurement, the selection of waterproof casing on both sides of the selection point. Waterproof casing axis positioning, should be based on waterproof casing on both sides of the selection point to carry out cross-type installation and positioning, so as to ensure that the waterproof casing installation parts and positioning, not easy to cause deviation and deformation. After the waterproof casing positioning, lifting the hole side construction, and fixed immobile waterproof casing according to the regulations, to avoid the waterproof casing in the pouring of the whole process of deviation.
 
3 . Make sure to install every little key point: in order to better prevent the prefabricated concrete waterproof casing after crossing the wall appears to seal and hole, be sure to ensure that the impact compressive strength of the concrete mix within the pre-buried casing and concrete mix perforation compaction. For large pre-buried casing, can be in the steel flexible waterproof casing template on both sides and then add shock power range holes. When the exterior wall of the housing building prefabricated concrete to waterproof casing at the bottom of the height and width ratio, the vibration compressive strength rod from the seismic power range hole stabbed into the waterproof casing under the edge and both sides to carry out the vibration compressive strength test, prefabricated concrete pouring after turning off the seismic power range hole. Sealability and tensile strength tests should be carried out before installing the waterproof casing.
