Utility model content
This utility model relates to a kind of vacuum and the structure of preloading joint preloading reinforcing soft ground, this structure it can be avoided that
A large amount of use medium coarse sand bed courses in conventional vacuum combined heap load precompacting such that it is able to overcome the defect consuming ample resources, and
Vacuum transmission efficiency can be effectively improved, it is to avoid occur that similar vacuum loses bigger situation in medium coarse sand bed course, from
And the consolidation time of software ground can be accelerated, improve the consolidation effect of soft soil foundation.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: vacuum and preloading joint preloading are reinforced soft
The structure of soil base, including the longitudinal plastic draining board being embedded in the soil body, described longitudinal plastic draining board 1 is arranged with horizontal seal
Water system connects, and lays geotextiles and diaphragm seal above horizontal seal drainage system successively, and diaphragm seal is pressed into the fortifield village of surrounding
Under weir, described horizontal seal drainage system is connected with outside vacuum pump by connecting tube.
The vacuum of this utility model offer and the structure of preloading joint preloading reinforcing soft ground, be to improve conventional vacuum
In combined heap load precompacting using medium coarse sand bed course as horizontal drainage and vacuum transmission system on the basis of, a kind of weak soil of formation
Foundation treatment technology.This utility model use horizontal seal drainage system substitute medium coarse sand bed course, it is possible to effectively to reduce engineering
Cost, improves vacuum transmission efficiency, it is achieved economic, efficient, the energy-conservation and target of environmental protection.This vacuum and preloading joint preloading add
Gu the structure of soft soil foundation can at harbour, railway, highway, water conservancy, the weak soil of the construction project such as airport or super soft ground work
Journey is widely applied.
