Since our country start to build high-speed railway for passenger, bridge engineering and tunnel engineering hold a large proportion. And it becomes a main force to stimulate concrete machinery and bridge special equipment of manufacture, transportation and erection.
The bridge engineering can be divided into concrete precast box-girder and cast-in-place concrete box-girder. It is mainly based on prefabricating simply supported box girder. The demands for equipment are concrete machinery, hoisting machinery, hydraulic steel template, steel bar processed equipments, bridge transport vehicle, bridge girder erection machine, power equipment, etc. no matter it is precast box girder or cast-in-place box girder, the production of concrete batching plant are all centralized. In plain area, it will install a concrete batching plant per 10~15 kilometers. Its production ability is about 100~150m3/h. its configuration is about 15~20 sets concrete mixer truck, 4~6 sets concrete mixer pump and other supporting equipment.
recast box girder mainly depends on concrete precast beam which is build per 20~30 kilometers. It produces precast concrete box girder (mainly including 20m, 24m and 32m. 32m with 900t are in the majority.) according to specific configuration. The manufacturer of concrete precast box girder mainly relies on the concrete batching plant, concrete mixer truck, concrete pump and steel bar processing machinery.
In the whole process of bridge engineering and tunnel engineering, concrete plays the most important part. Therefore, there is no doubt that those engineering can boost the demand for concrete batching plant, concrete mixer truck and concrete pump in recent years.
DASWELL MACHINERY specializes in manufacturing concrete batching plants, concrete mixers, etc.
