Summary of the invention
The utility model object is to provide the one water penetration test instrument of automatically testing pits.
For achieving the above object, the utility model is taked following technical proposals:
The water penetration test instrument of automatically testing pits described in the utility model, comprises water tank and the base being connected with this tank bottom wall, offers water tank retaining hole on the roof of described water tank; Be provided with the permeable draw-in groove with mesh in the internal vertical of water tank, electronic water level monitor is installed in permeable draw-in groove; Under water tank, filling pipe is installed, one end of filling pipe is connected with the apopore of offering in tank bottom wall, and the other end is test pit water injection hole, and this test pit water injection hole is arranged on base exterior; On described filling pipe, be provided with electric-controlled switch; The control input end of described electric-controlled switch is electrically connected with the control output end that is installed on the central controller in base; The signal input part of described central controller is electrically connected with the probe signal output terminal that is arranged on base exterior; On described probe, be respectively arranged with short probe and long probe; Described short probe length adjustable.
Described water tank roof is provided with horizontal bubble; Bottom at described base is provided with leveling serew.
On the sidewall of described water tank, be vertically installed with and be with graduated glass tube; The upper end of described glass tube is connected with the side-walls near water tank roof, and lower end is connected with the side-walls near tank bottom wall.
Described test pit water injection hole place is provided with mesh grille.
On described probe, be provided with protecting sheathing.
When the utility model advantage is to adopt this test instrument to test, control the opening and closing of electric-controlled switch by the resistance variations between probe place two probes, can control more accurately water injection rate, keep testing pits interior water level, the water level causing while avoiding manual control fluctuates excessive; Simultaneously, can gather more accurately the data of SEA LEVEL VARIATION in water tank by the electronic water level monitor arranging in water tank, the water penetration test work that makes to test pits departs from traditional manual operation and logging mode, realize the robotization of process of the test and data acquisition, the result of calculation of parameter will be more reliable, the test figure uniform format gathering, is convenient to arrange, analyzes and preserves.
