Description

Anti-slag drop device

technical field

The invention relates to the field of municipal construction tools, in particular to a device for preventing soil dregs from falling.

Background technique

In the construction of municipal road projects, there are many inspection wells in the road range. In order to ensure the smooth progress of barrier-free paving, improve the use efficiency and operating range of paving and rolling machinery, and improve the construction quality of each structural layer of the road (reduce mixture segregation, improve Flatness), we need to cover and conceal the position of the inspection well shaft under the road subgrade. After the construction of the road structure layer is completed, we will dig it to expose the position of the shaft shaft, build the shaft shaft, and install the well cover. Repeated concealment and excavation are required in the middle Second, in the process of backfilling and excavation, the original concrete cover was used to cover the concealment, which was more than 20 centimeters above the ground, which did not conform to the design concept of barrier-free paving construction method, and formed new paving obstacles, mechanical collisions during subsequent operations, etc. The reason is that the position is offset, the wellhead is not tightly covered, and the soil and residue can easily enter the well chamber, which is likely to cause accidents such as drainage pipeline blockage and professional pipeline damage. Due to the small space inside the well, it was very difficult to clean up later, and the workload was heavy.

Contents of the invention

In order to make up for the above shortcomings, the present invention provides a device for preventing soil and debris from falling into the inspection well with a simple structure.

Technical scheme of the present invention is:

A device for preventing soil slag from falling, characterized in that it includes a drop groove 3, the top of the drop groove 3 is provided with a groove edge 6, and the outer diameter of the groove edge 6 is smaller than the inner diameter of the inspection well; the outer diameter of the groove edge 6 is A sealing ring 2 is provided; a pair of handles 4 are fixedly arranged along the top surface of the groove 6, and at least three bolt holes 1 are fixedly arranged on the top surface of the groove along the 6; the screw rod 5 is threadedly connected with the bolt hole 1, and the screw rod 5 level settings.

As a preferred solution, three bolt holes 1 are fixedly arranged along the top surface of the groove 6 .

Further, the three bolt holes 1 are evenly distributed on the top surface of the groove edge 6 .

As a preferred solution, the outer diameter of the groove edge 6 is at least 20 mm smaller than the inner diameter of the inspection well. The outer clearance is adjusted with sealing ring 2.

As a preferred solution, the sealing ring 2 is a rubber sealing ring.

During the concealed backfilling or excavation process of the wellhead, in order to prevent the soil residue and the road structure mixture from falling into the inspection well, the soil residue falling prevention device of the present invention is installed at the wellhead. During construction, add a limit ring on the inner wall of the well near the wellhead, and add several fixing holes on the well wall; hold the handle, put the drop groove 3 into the wellhead, and after putting it down, the groove edge 6 is just in line with the limit Circle contact, rotating screw rod 5, the end of screw rod 5 is getting closer and closer from well wall, finally, screw rod 5 is screwed in the fixing hole on the well wall, realizes the installation and fixing of anti-slag falling device of the present invention. Because groove is provided with sealing ring 2 along 6 outsides, further guarantees to avoid earth slag and road structure mixture from falling into inspection well.

The beneficial effects of the present invention are:

The invention is simple in structure, easy to install and disassemble, and cleverly avoids the soil dregs and structural mixture falling into the inspection well during the hidden backfilling or excavation of the wellhead; 3 inside for easy cleanup.

detailed description

Example 1

As shown in Fig. 1, the falling groove 3 of the anti-slag falling device of the present invention has no special requirements on the depth of the falling groove 3, and its depth is generally between 30mm-300mm. A groove edge 6 is provided on the top of the drop groove 3, and the outer diameter of the groove edge 6 is at least 20mm smaller than the inner diameter of the inspection well. The groove is provided with rubber sealing ring 2 along 6 outsides.

A pair of handles 4 are fixedly arranged on the top surface of the groove along 6, which is convenient for moving; three bolt holes 1 are also fixedly arranged on the top surface of the groove along 6, and the three bolt holes 1 are uniformly distributed on the top surface of the groove along 6. The screw rod 5 is threadedly connected with the bolt hole 1, and the screw rod 5 is arranged horizontally.

During the concealed backfilling or excavation process of the wellhead, in order to prevent the soil residue and the road structure mixture from falling into the inspection well, the soil residue falling prevention device of the present invention is installed at the wellhead.

During construction, add a limit ring on the inner wall of the well near the wellhead, and add several fixing holes on the well wall; hold the handle, put the drop groove 3 into the wellhead, and after putting it down, the groove edge 6 is just in line with the limit Circle contact, rotating screw rod 5, the end of screw rod 5 is getting closer and closer from well wall, finally, screw rod 5 is screwed in the fixing hole on the well wall, realizes the installation and fixing of anti-slag falling device of the present invention. Because groove is provided with sealing ring 2 along 6 outsides, further guarantees to avoid earth slag and road structure mixture from falling into inspection well.

Using the present invention, soil residue and the like fall into the drop groove 3, thereby avoiding that soil residue and structural mixture fall into the inspection well during the hidden backfilling or excavation process of the wellhead.
