At the bottom of described bucket comprises barrel and barrel, the described bucket end, be connected with dish shape nut by straight pin, movable joint screw with barrel, and the described bucket end and barrel contact position are provided with O-ring seal.
The described plate upside that washes away is provided with the round rubber lid.
Described a plurality of column is installed on the base plate by packing ring and sunk screw.
The utility model compared with prior art has the following advantages:
(1) simple in structure, easy to use.This pneumatic type base material washout test apparatus structure is simple, only needs a people to get final product complete operation, and is very easy;
(2) volume is small and exquisite, is convenient to carrying.This pneumatic type base material washout test device volume is little, in light weight, and convenient disassembly is convenient to transportation very much;
(3) can realize accurate control to the flush water flowing pressure.This pneumatic type base material washout test device adopts external air pump that controlled pressure is provided, and has realized that the flush water flowing pressure in the washout test process is regulated arbitrarily.
(4) but real simulation the actual condition of washing away of road deck subbase, experimental result is reliable.This pneumatic type base material washout test device real simulation the actual condition of washing away of road deck subbase, comprise current wash away and pump is inhaled, positive and negative flowing pressure circulation change, test findings can be used for the quantitative test of pavement structure;
(5) production cost low, be convenient to promote the use of.The a lot of parts of this pneumatic type base material washout test device all are convenient to produce to buy very much, thus its produce and cost of use low, be convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.
