Quality control of glass fiber reinforced continuous wall

1. Raw material glass fiber bar access control
For the glass fiber bar entering the site, check whether there is product qualification certificate, and strictly check the size of each shaped fiber bar according to the large sample diagram, and then unload the car after passing the test.Glass fiber bars should be handled with care during loading, unloading and transportation.Glass fiber bars should be placed horizontally to avoid exposure to the sun.Special construction techniques should be prepared before construction, and implemented in the construction.
2. Key points of control of buckle joint
After the completion of the fiber cage connector, the project department requires it to be an inspection procedure, and the production of the next procedure can only be carried out after the acceptance is qualified.For the acceptance of joints, the project department shall strictly check according to the construction drawings, mainly checking whether the lap length is up to 40d as required by the design, whether the number of clasps satisfies no less than two clasps per joint, and the degree of tightening of the clasps.
Control points of poor stability of glass fiber cage skeleton itself
Fiber reinforced material has good toughness, fiber reinforced cage skeleton when lifting its stability is poor, easy to spread cage, so the project department for construction in strict accordance with the drawings adopt measures to increase the stiffness of glass fiber reinforcement cage, set the i-steel late package edge, and can remove steel truss and other methods to ensure its own stability when lifting.
4. The lifting process shall be completely bypassed
During the hoisting process of glass fiber cage, the project department insisted that the whole process should be bypassed.The main points of its side stations are:
First: because of the light quality of the fiber cage itself, the mud buoyancy is greater after it is put into the tank, which leads to the difficulty of dewatering. It is strictly prohibited for the construction team to enter the tank by force.
Second, the construction team is strictly required to cut the added steel truss and the i-steel envelope edge of the intrusion shield end, so as not to leave a hidden danger for the future shield construction.
Third: strictly check the quality of the joint between the steel cage and the fiber cage.
