Description
Technical Field
The utility model relates to a pile foundation pore-forming technical field specifically indicates a high backfill area of earth and rock digs soon and adds compound dry method of punching a hole toper impact hammer for pore-forming.
Background
At present, when a rotary drilling rig is used for forming holes in an earth and rock high-backfill region, due to the fact that the compactness of a backfill soil body is insufficient and the self-stability is poor, hole collapse easily occurs when the holes are formed through rotary drilling, at the moment, low-grade concrete is adopted for recharging in a conventional method, then the holes are drilled again, and the rotary drilling rig is very troublesome, not only wastes time and resources, but also cannot guarantee that the holes can be formed once after recharging.
To sum up, the applicant provides a conical punch hammer for rotary excavating and punching composite dry-method hole forming in an earth and rock high backfill area.
SUMMERY OF THE UTILITY MODEL
In view of the problem in the prior art that the pile foundation construction collapse hole is dug soon in the high backfill region of gravel and earth, a conical punch hammer for hole forming by a rotary digging and punching composite dry method is provided, which solves the problem.
In order to realize the technical purpose, the utility model discloses a technical scheme as follows:
a conical punch hammer for rotary drilling and punching combined dry-method hole forming in an earth and rock high backfill area comprises a barrel and a conical head, wherein the conical head is arranged at the bottom of the barrel, the barrel and the conical head are hollow, the outer diameter of the barrel is consistent with the diameter of a drill bit of a rotary drilling rig, a lifting hole matched with a punching machine is arranged in the center of the top of the barrel, and concrete is poured into the barrel and the conical head to increase weight; through a specially-made conical impact hammer, when a rotary drilling rig is used for drilling holes in a high earth and rock backfill region to form collapsed holes, pile holes are firstly backfilled to about 1m above the collapsed hole position by using pile foundation dregs nearby, then a special conical impact hammer is used for compacting the soil in the holes towards the periphery by using an impact pile machine, and the rotary drilling rig is used for normally rotary drilling the holes after the soil crosses the collapsed hole region. The soil around the pile foundation is tamped and compacted by the conical impact hammer, so that the self-stability of the soil is improved, and the problem of hole collapse in rotary drilling is effectively solved. The construction technology does not need concrete recharging, does not need to wait for concrete hardening, does not produce waste slag, does not pollute the environment, saves resources and time, and is very environment-friendly.
Further limiting, the cylinder body is hollow and cylindrical, and the conical head is conical; the cylindrical and conical soil body is more beneficial to compacting the soil body by ramming, and the effect is better.
Further, the cylinder body and the conical head are both made of steel; the cylinder body and the conical head are made of steel, are firm and durable and are not easy to deform.
The utility model discloses compare in prior art's beneficial effect for more convenient, high-efficient in the drilling of high backfill region of earth and stone to practice thrift manpower and materials, simple structure, low in cost, long service life.

Detailed Description
In order to make the technical solution of the present invention more comprehensible to those skilled in the art, the present invention is further described with reference to the accompanying drawings and examples.
As shown in fig. 1-3, the conical punch hammer for rotary drilling and punching composite dry-method hole forming in the high earth and rock backfill region comprises a cylinder body 1, a conical head 2, a hanging handle 3 and a stiffening plate 4, wherein the conical head 2 is arranged at the bottom of the cylinder body 1, the cylinder body 1 and the conical head 2 are both hollow, the size of the cylinder body 1 is consistent with the diameter of a drill bit of a rotary drilling rig, the hanging handle 3 is arranged in the center of the top of the cylinder body 1, a hanging hole 3-1 matched with a punching pile driver is formed in the hanging handle, the stiffening plate is arranged between the hanging handle 3 and the cylinder body 1 to enhance the linkage between the hanging handle and the cylinder body, and a filler 5 is further arranged inside the cylinder body 1 and the conical head 2 to increase weight; the filler 5 is concrete; the cylinder body 1 is a hollow cylinder, and the conical head 2 is conical; the cylinder body 1, the conical head 2, the hanging handle 3 and the stiffening plate 4 are all made of alloy steel.
By arranging the conical rammer, when a rotary drilling rig is used for drilling collapsed holes in a high earth and rockfill backfilling area, pile holes are backfilled to about 1m above the collapsed hole position by using pile foundation slag soil nearby, then a special conical rammer is used for compacting the soil in the holes to the periphery by using an impact pile machine, and the rotary drilling rig is used for normally rotary drilling to form the holes after the soil crosses the collapsed hole area. The soil around the pile foundation is tamped and compacted by the conical impact hammer, so that the self-stability of the soil is improved, and the problem of hole collapse in rotary drilling is effectively solved. The conical impact hammer does not need concrete recharging, does not need to wait for concrete hardening, does not produce waste slag, does not pollute the environment, saves resources and time, and is very environment-friendly. The method adopts concrete to weight the conical punch hammer, has low manufacturing cost and convenient material use; the cylindrical and conical shapes are manufactured, so that the soil body is more favorably compacted and compacted, and the construction effect is better; the cylinder body and the conical head are made of steel, are firm and durable and are not easy to deform.
The utility model discloses compare in prior art's beneficial effect for more convenient, high-efficient in the drilling of high backfill region of earth and stone to practice thrift manpower, material resources and material, simple structure, low in cost, long service life.
It is right above the utility model provides a high backfill region of earth and stone digs soon and adds compound dry process for pore-forming toper impact hammer of punching a hole and introduces in detail, and the description of concrete example is only used for helping understanding the utility model discloses a method and core thought thereof. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
