Description
Technical Field
The utility model relates to a road surface construction detects technical field, especially relates to sand filling method detects compactness pore-forming ware.
Background
The sand filling method is adopted to test the compaction degree of a base layer or a subbase layer, a sand-gravel road surface and a roadbed structure on site so as to evaluate the compaction quality of a structural layer, and a test pit with a certain diameter and depth needs to be dug on site. In the prior art, a square plate is paved on the ground to determine the position of a pit, and holes are formed by a board chisel, a screwdriver, an iron hammer, a long-handle spoon, a long-handle small dustpan, a brush and the like, so that time and labor are consumed.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the not enough of existence among the above-mentioned prior art, provide the sand filling method and detect compactness pore-forming ware.
The utility model provides an above-mentioned technical problem's technical scheme as follows: sand filling method detects compactness hole former, including fixing device and drilling equipment, fixing device is hollow fixed disk, drilling equipment is including protecting a section of thick bamboo, power transmission section of thick bamboo, drilling rod and bull stick, protect a section of thick bamboo and power transmission section of thick bamboo integrated into one piece, drilling rod and bull stick integrated into one piece, the inside internal thread that sets up of power transmission section of thick bamboo, contain the external screw thread with internal thread looks adaptation on the drilling rod, the bull stick rotates and drives the drilling rod and reciprocate in power transmission section of thick bamboo, the drilling rod bottom still includes the drill bit, protect a section of thick bamboo external diameter with hollow fixed disk internal diameter joint is in the same place.
Further, the diameter of the rotating rod is larger than that of the hollow fixed disc.
Further, the drill bit is a blade drill bit.
Furthermore, an outlet hole is chiseled on the protective cylinder.
Further, the drill bit is welded at the bottom of the drill rod.
Further, the drill bit is a special drill bit for digging a pit.
Compared with the prior art, the beneficial effects of the utility model are that: the rotating rod rotates to drive the drill rod to rotate, the blade drill bit drills and digs, the hole is drilled to discharge sand and stone, the hole forming efficiency is high, and manpower is saved.

Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1-3, the sand-filling method detects compaction degree pore-forming ware, including fixing device and drilling equipment, fixing device is hollow fixed disk 1, drilling equipment is including protecting a section of thick bamboo 2, power transmission section of thick bamboo 3, drilling rod 4 and bull stick 5, protect a section of thick bamboo 2 and power transmission section of thick bamboo 3 integrated into one piece, drilling rod 4 and 5 integrated into one piece of bull stick, the inside internal thread that sets up of power transmission section of thick bamboo 3, contain the external screw thread with internal thread looks adaptation on drilling rod 4, bull stick 5 rotates and drives the drilling rod and reciprocate in power transmission section of thick bamboo 3, drilling rod 4 bottom still includes drill bit 6, protect a section of thick bamboo 2 external diameter with 1 internal diameter joint of hollow fixed disk is in the same place. The diameter of the rotating rod 5 is larger than that of the hollow fixed disk 1. The drill bit 6 is a blade drill bit. An outlet hole 7 is chiseled on the protective cylinder 2. The drill bit 6 is welded to the bottom of the drill rod 4. The drill bit 6 is a special drill bit for digging a pit.
Principle of operation
When a test for detecting the compaction degree by a sand filling method is carried out, the hollow fixed disc 1 is placed at a sampling point, a drilling device is installed, the rotating rod 5 is rotated to enable the drill 5 and the drill bit 6 to move downwards, sandy soil is excavated, after a certain depth is reached, the rotating rod 5 is rotated in the opposite direction to enable the drill rod 4 and the drill bit 6 to move upwards, the sand taken out is discharged from a hole, the drilling device is taken down, and redundant soil is excavated for the test.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
