The other end of horizontal drainage general pipeline connection, the first draining branch pipe(tube) is connected to an other horizontal drainage general pipeline.
8. the horizontal drainage system according to claim 1 for solidification soft foundation, which is characterized in that on subgrade ground
Edge and several second draining branch pipe(tube)s are provided between the horizontal drainage general pipeline at subgrade ground edge, described second
The successively adjacent four-way water guide that branch drain road will be arranged by several horizontal drainage branch in C font or mirror image C font
Part is connected in series；It is opened with one of the horizontal drainage general pipeline close to subgrade ground edge one end of the second draining branch pipe(tube)
Mouthful connection, another open communication of the other end and the horizontal drainage general pipeline close to subgrade ground edge.
9. the horizontal drainage system according to claim 1 for solidification soft foundation, which is characterized in that the system further includes
At least one water pump；The pump mouth of the water pump is set in sump module；The water pump is for taking away in sump module
Ponding.
10. a kind of construction method of the horizontal drainage system for solidification soft foundation as described in claim 1-9 is any, special
Sign is, the construction method the following steps are included:
Step 1, the measurement markers on the ground of subgrade, so that it is determined that sump module, horizontal drainage general pipeline and horizontal drainage
The installation site of branch pipe；
Step 2, and the corresponding groove of each horizontal drainage general pipeline and heatable adobe sleeping platform corresponding with each sump module is excavated；
Step 3, by several sump modules install in corresponding heatable adobe sleeping platform and by several horizontal drainage general pipeline install in
In corresponding groove, realizes each horizontal drainage general pipeline by terminal or corresponding sump module and be interconnected, often
A sump module is at least connected to the end of a horizontal drainage general pipeline；
Step 4, array is respectively laid with several vertical collector pipes in subgrade, keeps the end of the vertical collector pipe of each item prominent
For subgrade ground, the rest part of each vertical collector pipe of item is vertically embedded in subgrade；
Step 5, several four-way water parts are installed on the ground of subgrade, make the vertical collector pipe for protruding from subgrade ground
End is connected to corresponding four-way water part；
Step 6, several horizontal drainage branch are installed on the ground of subgrade, each four-way water part is made to pass through corresponding water
Flat branch drain forms several branch drain roads, and each branch drain road is connected to corresponding horizontal drainage general pipeline, thus
Form the drainage network that ponding converges at sump module；
Step 7, the stacking pressure gravity heap pressurized layer above subgrade.
