Case；The flat water tank is equipped with outlet pipe and is connected to the main pipeline；The main pipeline is equipped with control valve.
In other words, structure of the invention design is: the large scale field test simulator of sub-bottom changes piping dangerous situation is shown in
Attached drawing, by water blocking dykes and dams, L shape armored concrete board wall, pressure tank, flat water tank, supervisor, floral tube, control valve group at.
Water blocking dykes and dams are sub-bottom changes, are filled by code requirement；Sub-bottom changes are divided into two by L shape armored concrete board wall
Part is water blocking part before wall, stablizes safety and meets code requirement, is dangerous situation analog portion after wall；Pressure tank is set to dike
On top, water pump is inside set；Flat water tank is placed by wall；Control valve is manual and electric double-purpose butterfly valve；Predominant tube diameter 10cm；Aperture floral tube diameter
5cm。
Key technology content
(1) testing ground sets the pond of soil property water blocking dykes and dams formation, and dykes and dams height is not less than 3m, and the depth of water is not less than 2.5m；
(2) it is the safety for guaranteeing sub-bottom changes, dykes and dams is divided into water blocking part and dangerous situation analog portion, therebetween with " L " board wall point
Every the piping dangerous situation of simulation is located in board wall；
(3) to make the control of piping dangerous situation time of origin within 15 minutes, aperture floral tube top thickness of earth covering is less than 40cm, the soil body
Infiltration coefficient require be greater than 10-3cm/s；
(4) it is the time improved head difference, shorten the generation of piping dangerous situation, pressure tank is set on dykes and dams, and tank height is big
In 1m；
