Description

Shaping mold for the construction of rapid flow tank

technical field

The utility model relates to the field of road construction, in particular to a shaping die for the construction of a rapid flow trough.

Background technique

In the traditional rapid trough construction process, if the outer side of the rapid trough is not compacted, it will leave a hidden danger to the stability of the slope, that is, the joint between the rapid trough and the slope is most severely damaged during the rain erosion process, which seriously affects the stability of the subgrade. Stability greatly shortens the service life of the rapids and roads.

The reasons for the above problems are as follows: 1. Improper setting of the longitudinal and transverse ribs of the wooden formwork may lead to insufficient rigidity of the formwork, which makes the appearance of the rush trough rough and the line shape is not straight; 2. With the increase of the number of turnovers, the wooden formwork will show different degrees If it is not replaced in time, it will seriously affect the quality of the finished jet trough, especially the appearance quality; 3. It is difficult to control the size of the foundation trench by mechanical excavation, and it may be too large or too small, which will bring inconvenience to subsequent construction; 4. After the groove is excavated, in order to facilitate the formwork support, a certain space is often left. If the space is too small, it is inconvenient to support the formwork and cannot meet the backfill and compaction requirements of the subsequent rapid flow groove. If the space is too large, the subsequent backfill amount will be increased; 5. The rapid flow groove The backfilling and compaction of the outer space is located on a slope, so the work is difficult, time-consuming, laborious, slow in progress and easy to damage the jet channel during the compaction process; 6. It is difficult to control the quality of the backfill and compaction of the outer space of the jet channel. If the compaction is not dense, the slope will be unstable. Leaving hidden dangers, according to previous cases, this place is the most serious in the process of rainwater erosion, which seriously affects the stability of the roadbed and greatly shortens the service life of the rapids and the road.
