a) The same distance between the pieces of the water drenching filler assembly block shall meet the design requirements, and the allowable deviation shall be 1.0mm of soil. The adjacent surfaces of the assembly block shall be perpendicular to each other to form a regular hexahedron, and the plane formed by the edges of each piece shall be flush and consistent.
B) The bonding points between the sheets in the assembly block shall be firmly bonded without separation. The effective bonding points between the sheets shall not be less than 90% of the total number of bonding points between the sheets.
C) The assembly block shall have sufficient rigidity. Under the uniform arrangement of 3000N/m, the supporting surface and loading surface of the standard specimen under the simple support condition shall be free of obvious deformation such as core bending and lodging, and the lateral displacement of the part shall not be greater than 50mmc.
d) The through-rod assembly block shall be equipped with sufficient plastic tie rods. The mechanical properties of the tie rod for assembly shall meet the mechanical properties requirements of the dewatering rod, and the mechanical properties of the tie rod for hoisting shall meet the calculation requirements of foot stiffness and strength.
a) The special binder for PVC plastic filler shall be prepared from vinyl chloride compound. Under various ambient temperature conditions, its bonding curing performance should meet the requirements of the bonding assembly process.
B) the special adhesive for PVC plastic filler can be divided into ordinary type and low-temperature quick-drying type according to its curing temperature. when the bonding environment temperature is lower than 10t: low-temperature quick-drying adhesive should be used.
C) The bonding strength of the adhesive shall meet the requirements. Acceptance group approval of drenched filler
The acceptance of drenched filler shall be in batches. With the same raw materials, formula, specifications, process of continuous production of flat sheets and their molded pieces, assembly blocks for a batch, each batch of the maximum number of not more than 30.
