Description

Cement impervious wall water injection test device

Technical Field

The utility model relates to a check out test set technical field, more specifically say, relate to a cement soil cut-off wall water injection test device.

Background

In the prior art, when a hydraulic engineering cement soil impervious wall is detected on site, a drilling machine is used for drilling a hole in a cement soil impervious wall body, a certain amount of clean water is injected, according to the injected water amount in different time periods or the descending amount of water level in different time periods, the permeability coefficient of a soil body in a water seepage section of the wall of the hole is detected, water is generally filled, the water is observed once within 5-30 minutes, the water level descending displacement is generally measured once within 2 hours in the later period, and a steel tape is usually adopted for measuring the descending displacement of the water level.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a cement soil cut-off wall water injection test device, the device can drive the buoy displacement from top to bottom through the change of downthehole water level, can solve reading error and the special person on duty in the present water injection experiment detects, the problem that work load is big.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

the utility model provides a soil cement cut-off wall water injection test device, the power distribution box comprises a box body, box front panel be transparent ya keli panel, box top panel and lower panel center correspond position department and all open a big or small the same through-hole, through-hole inside runs through a buoy guide arm about wherein, the vertical inside and below of box that runs through of buoy guide arm be fixed with the buoy, be located the inside buoy guide arm rear of box and be fixed with the scale, be located the inside buoy guide arm of box on vertical equidistance be equipped with a plurality of locating part, the locating part include spacing ring and cradling piece, the spacing ring encircle to set up in buoy guide arm periphery and rear and scale fixed connection, cradling piece one end and spacing ring integrated into one piece and other end and box inside fixed connection, four corner position departments of box below all be equipped with the supporting leg.

Furthermore, the buoy adopts a hollow plastic ball.

Furthermore, the buoy guide rod can move up and down freely in the through hole and the limiting ring.

Furthermore, the adjacent distance between the limiting parts is 5-6 cm.

Compared with the prior art, the utility model has the advantages that:

the utility model discloses in combine the box structure to realize the measurement work to the downthehole water level of drilling wall body through buoy guide arm and buoy, combine the scale directly to read the water level parameter of each time quantum, when being convenient for survey water level variation, greatly reduced artifical working strength who detects many times, improved the accuracy that detects data.

Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

in the figure: 1. a float guide bar; 2. a box body; 3. a graduated scale; 4. a limiting member; 5. a float.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the utility model easy to understand and understand, the utility model is further explained by combining with the specific figures.

As shown in figure 1, a cement impervious wall water injection test device comprises a box body 2, a front panel of the box body 2 is a transparent acrylic panel, through holes with the same size are respectively arranged at the corresponding positions of the centers of an upper panel and a lower panel of the box body 2, a buoy guide rod 1 penetrates through the upper through hole and the lower through hole, a buoy 5 is vertically arranged in the box body 2 and fixed below the buoy guide rod 1, a graduated scale 3 is fixed behind the buoy guide rod 1 in the box body 2, a plurality of limiting parts 4 (nine in the figure and actually determined according to the length of the buoy guide rod 1) are vertically arranged on the buoy guide rod 1 in the box body 2 at equal intervals, each limiting part 4 comprises a limiting ring and a support rod, the limiting rings are arranged around the periphery of the buoy guide rod 1 and fixedly connected with the graduated scale 3 at the rear part, one end of the support rod is integrally formed with the limiting rings, and the, supporting legs are arranged at four corner positions below the box body 2, the buoy 5 is a hollow plastic ball, the buoy guide rod 1 can freely move up and down in the through hole and the limiting ring, and the adjacent distance between the limiting parts 4 is 5-6 cm.

During on-site detection, clear water is injected into the water injection hole, the box body 2 is horizontally placed and fixed right above the water injection hole, the buoy 5 floats on the water surface in the water injection hole, the buoy guide rod 1 can float up and down in the limiting ring and the through hole, a calibration position can be marked on the buoy guide rod 1, the initial reading value of the calibration position of the buoy guide rod 1 on the graduated scale 3 at the moment is recorded, after T1 time, the buoy 5 descends to drive the buoy guide rod 1 to descend, the reading value of the graduated scale 3 corresponding to the calibration position of the buoy guide rod 1 at the moment is recorded again, and by analogy, according to the detection time requirement, T2, T3, T4 and T5 reading values of the corresponding graduated scale guide rod 1 are recorded once, the detection value is obtained through simple addition and subtraction operation at the later stage, and after the test is completed, the whole device is folded to perform the detection work of the next water injection hole.

The basic principles and main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
