Specifically, the embodiment of the present invention additionally provides a kind of experiment side of horizontal box hidden pipe filtrate laboratory apparatus 100
Method is：
S1：Galvanized steel plain sheet is welded into the case body 101 of uncovered successively；
Wherein, container inner wall since away from top 20cm every one circle Φ 10mm reinforcing bars of 20cm welderings as water baffle bar 131,
Prevent current along chamber wall produce it is uneven under ooze.The bottom that container is put into high 0.2m is taken.In 101 length direction one of case body
End, in the centre of plate, away from a Φ 110mm holes are opened at bottom plate 40cm, which is determined as 103 tail end 117 of hidden pipe.And the end plate away from
A hole is opened at the 10cm of top, connects the water nozzle of an outside diameter 20mm, is container water inlet tap 139.Among the container other end, away from bottom plate
A Φ 110mm holes are opened at 40.6cm, which is determined as 103 head end 115 of hidden pipe.As preferable scheme, to prevent box container
Steel plate is outwards supportted in long direction after banketing, the strengthening frame 135 made with building scaffold is reinforced.
S2：Banket for the first time, impurity in soil is removed, sieve, container is inserted in then compaction in layers, then cloudy real with water, is filled out
Untill first perforate 109 is with the lower section of the second perforate 111；
S3：Hidden pipe 103 is installed, if sandstone filtrate, bottom material is first completed and hidden pipe 103 is installed again, if non-woven fabrics
Or shredded coconut meat etc., filtrate is first carried out, then install, ensure hidden pipe 103 vertically to not bending；
Wherein, 110 hidden pipes of Φ, 103 tubing 2.4m is intercepted, both ends respectively stay 0.3m not punch.The hole opened by container both ends will
The hidden pipe 103 processed loads container, and 0.2m is respectively revealed at container both ends.
S4：Banket, banketed to apart from the 101 top 10cm of case body for the second time；
S5：Add water, open the water inlet tap 139 of the water tank 105 and the valve 137 on the faucet 141,
Start in the case body 101 plus water；
Wherein, open water tank 105 and pass in and out valve 137 on water nozzle 141, start in case body 101 plus water.Because of water tank 105
Middle installation float switch, 105 water level of water tank are remained in the middle part of water tank 105, the low 10cm in 105 middle part container top of water tank,
So water level can remain lower 10cm than top in case body 101.
