Description

Sand filling hole drilling device

Technical Field

The utility model relates to a road construction equipment, specific theory relates to a irritate sand and bore ware.

Background

At present, the compaction degree of a municipal road engineering subgrade is a quality control index of soil filling engineering, but the method in use at present is that a hammer is matched with a long nail to dig soil, and meanwhile, a shovel is used for collecting dug road lime soil, backfilled plain soil and the like, but because the municipal road engineering battle line is long and narrow, when samples are collected according to the standard after being paved in a large area, a large amount of time of personnel is undoubtedly wasted.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides a chisel for loosening the soil, which can reduce the loss of chiseling and ensure the accuracy of the detection of the compactness; the labor amount is effectively reduced, the labor intensity of constructors is reduced, the labor cost is reduced, and the construction period is saved; reduce the time required by sampling and improve the construction efficiency.

The utility model adopts the technical proposal that:

a sand filling hole drilling device comprises a drilling machine, wherein an impeller is arranged on the drilling machine; a protective barrel is arranged around the impeller; the inner side of the impeller is fixedly connected with a drilling machine and is in a spiral ascending shape; the rear end of the protective barrel is connected with the drilling machine.

The inner diameter of the protective barrel is phi 150, and the length of the protective barrel is 200 mm.

The thickness of the front end wall of the protection barrel is smaller than that of the rear end wall.

The front end of the impeller extends out of the front end of the protective barrel; the extension length is as follows: 2-3 cm.

The utility model discloses relative prior art's beneficial effect:

the utility model reduces the loss of chiseling and loosening soil and ensures the accuracy of compaction detection; the labor amount is effectively reduced, the labor intensity of constructors is reduced, the labor cost is reduced, and the construction period is saved; the time required by sampling is reduced, and the construction efficiency is improved. When the roadbed compaction is detected, the sand-filling hole drill is used for effectively and accurately taking out the loosened material, placing the loosened material into a plastic bag with known mass and sealing the plastic bag.

FIG. 2 is a schematic cross-sectional view of FIG. 1 at 1-1;

fig. 3 is a schematic sectional view of fig. 1 at 2-2.

In the drawings, the main parts are illustrated by symbols: in the figure: 1. Drilling machine 2, impeller 3, protection bucket.

Detailed Description

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

as can be seen from the attached figures 1-3, the sand-filling hole-drilling device comprises a drilling machine 1, wherein an impeller 2 is arranged on the drilling machine; the periphery of the impeller 2 is provided with a protective barrel 3; the inner side of the impeller 2 is fixedly connected with the drilling machine 1 and is in a spiral rising shape; the rear end of the protective barrel 3 is connected with the drilling machine 1. The protective barrel 3 rotates synchronously with the drilling machine 1.

The inner diameter of the protective barrel is phi 150, and the length of the protective barrel is 200 mm.

The thickness of the front end wall of the protection barrel is smaller than that of the rear end wall.

The front end of the impeller 2 extends out of the front end of the protective barrel 3; the extension length is as follows: 2-3 cm.

The utility model reduces the loss of chiseling and loosening soil and ensures the accuracy of compaction detection; the labor amount is effectively reduced, the labor intensity of constructors is reduced, the labor cost is reduced, and the construction period is saved; the time required by sampling is reduced, and the construction efficiency is improved. When the roadbed compaction is detected, the sand-filling hole drill is used for effectively and accurately taking out the loosened material and placing the loosened material into a plastic bag with known quality.

The utility model discloses in actual compactness sample collection, can the effectual primitive of guaranteeing to gather the sample, simultaneously more effectual time of having reduced the collection sample has improved work efficiency greatly.

The collection method in the prior art has low efficiency and occupies personnel and time, so that the construction period of normal construction is delayed, and the effectiveness of a sample is poor.

The utility model discloses irritate sand borer, the diffusion of moisture in the reduction soil property that the baffle can be better, the impeller can go into the collecting vessel with the better collection of current road soil property in to can strictly guarantee that the volume of gathering the sample is unchangeable, prevent to scatter the sample that the chisel caused. And because this instrument is the rig class, has saved the manpower completely, has reduced a large amount of time, has improved work efficiency, has reduced construction cost on the premise of guaranteeing construction quality, has practiced thrift construction period, has improved the accuracy of sample data.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the structure of the present invention in any way. All the simple modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention all fall within the scope of the technical solution of the present invention.
