Lightweight foam concrete machine for road bridge back roadbed replacement
The foam concrete produced by the lightweight foam concrete machine is used in the replacement of road bridges because of its light and high strength, uncompressible, high mobility, and so on, which provides a new solution for some difficult problems in the design and construction of the road bridge, the foam concrete can effectively absorb the impact energy and can choose the corresponding density and strength according to the design requirements in the construction, greatly increased the convenience of construction, and shorten the construction cycle.
1. Lightweight foam concrete machine for road bridge back roadbed replacement
The lightweight foam soil filled between the bridge platform and the roadbed junction can slow and uniformize the gradient change of the sedimentation curve near the bridge platform and the roadbed junction. Its advantages are mainly reflected in the following:
It can greatly reduce the load of filling soil, reduce the additional stress of the soft base, inhibit the subsidence and side shift of the soft base, and improve the stability of the embankment.
to relieve the rigid mutation of the material of the bridge platform and the roadbed binding part;
Completely eliminate the post-work subsidence of the filler itself;
Filling the soil itself can stand on its own two feet, and has little push and selonging effect on the structure of the bridge platform;
The construction period is short.
2. Lightweight foam concrete machine for road widening
Foam concrete has a small weight, good mobility, curing can stand on its own feet and other characteristics. When this material is used to widen roads, it has some of the following advantages:
Vertical reclamation, land savings, reduced demolition, saving investment. When expanding the soil in the soft-based road section, the weight of the filling and the settlement difference between the old and new embankments can be greatly reduced.
No mechanical vibration and crushing is required during construction.
Through the pipe pumping foam concrete, the working surface is small, and almost does not affect the existing traffic.
The construction period is short, which can make the project put into use in advance, and bring the investors advanced income.
3. Lightweight foam concrete machine for bridge reductionThe use of the light soil filling bridge platform back of the current pouring foam can solve the problem of soil pressure and the platform front cone slope, optimize the bridge platform as a simple single row pile-type bridge platform and reduce the increase of the bridge span due to the cone slope, greatly reducing the construction cost.
