Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

the first embodiment is as follows:

referring to fig. 1 to 3, the device for sampling slurry in the groove of the underground diaphragm wall comprises a sampling barrel and a measuring rope 1, wherein the measuring rope 1 is matched with the depth of the underground diaphragm wall, the sampling barrel comprises a barrel body 3, a top cover plate 4 is arranged at the top of the barrel body 3, a bottom cover plate 5 is arranged at the bottom of the barrel body 3, and openings/holes are formed in the top cover plate 4 and the bottom cover plate 5 to allow slurry to flow into the barrel body. Wherein, the top cover plate 4 is provided with a top rubber pad 6 which is fixedly connected with the top cover plate 4 by a top bolt and a nut 8 in an elastic manner, and the top rubber pad 6 is arranged at the outer side of the sampling barrel 3; the bottom cover plate 5 is provided with a bottom rubber pad 7 which is fixed by a bolt and a nut 9 and can be fixedly connected with the bottom cover plate 5 in an elastic manner, and the bottom rubber pad 7 is arranged on the inner side of the sampling barrel 3. Lifting lugs 2 are arranged on the barrel wall of the sampling barrel at the top cover plate 4, and the measuring rope 1 is connected with the sampling barrel 3 through the lifting lugs 2. Thus, the openings/holes in the top cover plate 4 and the bottom cover plate 5 are covered by the top rubber pad 6 and the bottom rubber pad 7.

Preferably, the top cover plate 4 and the bottom cover plate 5 are connected with the barrel body 3 into a whole in a welding mode, and can also be detachably fastened and covered. The sampling barrel 3 is made of metal (such as a steel pipe) and is wear-resistant and durable, the barrel body 3 is cylindrical, and the top cover plate 4 and the bottom cover plate 5 are circular and are matched with the barrel body 3. The closed cushion block 7 positioned at the lower end can also be provided with a poking block 70, the poking block 70 is convexly displayed on the outer side of the lower end of the sampling barrel, and the closed cushion block 7 can be manually opened through the poking block 70.

When getting thick liquid, will sample bucket 3 through survey 1 direct puts the inslot of restricting, rely on sample bucket 3 dead weight to transfer, the in-process top of transferring, end rubber pad 7 receive the mud resistance effect and open automatically, according to the suggestion of surveying the rope, transfer the appointed degree of depth and take a sample, get thick liquid bucket 3 and receive the effect of mud resistance at sunken in-process rubber pad and open automatically, gather the mud of the different degree of depth. Then, the slurry taking barrel is directly lifted, and when the lifting barrel body 3 is pulled back, the top cover plate rubber pads and the bottom cover plate rubber pads are automatically closed under the resistance of the slurry on the upper part, so that the barrel body, the top cover plate rubber pads and the bottom cover plate rubber pads form a closed space. When the sampling bucket is lifted, the rubber pads are automatically closed and sealed by the aid of the flexibility of the rubber pads, and the top cover plate rubber pads, the bottom cover plate rubber pads and the bucket body can form a closed sampling bucket. The rubber pad that opens before forms a sealed space at the closed under the effect of resistance, seals mud in the sampling bucket, has blocked the replacement with different degree of depth mud at the in-process that rises, can guarantee that each item index of mud is true reliable to provide real data for clearing the hole, guarantee the quality of clearing the hole. Promote after the sample and get thick liquid bucket top apron and end cover board rubber pad automatic closure under the effect of resistance, with the sealed promotion of the mud in the sample bucket, avoided promoting the mud of the different degree of depth of in-process and mixed the bucket mud, improved the precision that detects.

Example two:

on the basis of the first embodiment, the present embodiment is further improved, as shown in fig. 4, the structural improvement different from the first embodiment includes:

the closure pad 6/7 is mounted to the cover 4/5 by a hinge 10 and the closure pad 6/7 is pivotable about the hinge 10 to open and close the opening. The block 6/7 may also be provided with a lift tab 11 for lifting the block 6/7. The closing pad 6/7 may be a hard rubber material and may be harder than a generally soft material.

The inside of sampling bucket 3 is equipped with the spacing structure of measurationing of protractile. The limiting and measuring structure comprises a measuring rod 12, the measuring rod 12 is movably arranged on the cover plate 5 at the lower end of the sampling barrel 3 in a penetrating mode, and a limiting bottom block 13 is arranged at the bottom of the measuring rod 12. The measuring rod 12 is telescopically inserted into the cover plate 5 at the lower end, and the measuring rod 12 is provided with scale marks 14. Therefore, when the sampling barrel sinks, more and more slurry is in the barrel, the measuring rod 12 is gradually pressed out of the barrel by the slurry, the scale marks 14 on the measuring rod 12 can be used for referring to the sinking depth, and the limiting bottom block 13 can play a limiting supporting role on the measuring rod 12 to prevent the measuring rod 12 from shaking back and forth.

Other structures are basically the same as those of the first embodiment, and thus further description is omitted.
