The requirements for formwork used in the construction of precast concrete components are very strict

The formwork requirements for the construction of prefabricated concrete components are very strict and need to be designed and customized according to the building. Most of the formwork used is disposable and the cost is high. It is best to use export formwork for important parts such as corners, beam and column joints.

The formwork must have sufficient stiffness, and no deformation is allowed under the lateral pressure of the concrete, to ensure uniform geometric dimensions and consistent cross-sections of the structure, and to prevent the loss of slurry; there are also high requirements for the materials of the formwork, the surface must be flat and bright, with high strength, corrosion resistance, and certain water absorption; for the joints of the formwork and the bolts that fix the formwork, the joints are required to be tight, and sealing strips must be added to prevent slurry from running.

The secondary structural column delivery pump adopts the principle of hydraulic S-valve tube delivery. It can not only deliver mortar quickly and effectively, but also transport mortar with stones smoothly. It is also very convenient to clean the pipeline after use. You only need to rinse it with clean water until there is no mortar. There is no need to repeatedly disassemble the pipeline. It saves trouble and effort. Everything is considered for the smooth construction of the user.

This equipment is widely used in secondary pouring construction of construction projects, anchor grouting, consolidation grouting and backfill grouting projects such as highways, railway tunnels, urban subways, underground caverns of hydropower stations, slopes, and grouting projects of anchor piles in soft rock reinforcement. Secondary structural column pump products are suitable for the transportation of fine stone concrete in various engineering constructions, the transportation of refractory and thermal insulation materials, the transportation of green soil in ecological environment construction, and the pressure grouting of various foundation piles. The secondary structural column delivery pump product is a fine stone mortar delivery equipment specially developed for the characteristics of secondary structural construction of buildings. It is suitable for large-area and high-efficiency construction of the mortar filling layer in secondary structural column projects.
