Abstract

The utility model belongs to the technical field of the civil engineering, specifically provide a be used for quick prosthetic drill bit of stake hole pore wall, it is including boring the body, it is the cylinder to bore the body, hold including first end and second, it is connected with an interface end to bore the first end of the body, the second end of boring the body is a cone, the shape of interface end is a square cylinder, be equipped with a plurality of pinholes on the square cylinder. Through the utility model provides a drill body comes to extrude the filler material of the hole pore wall that collapses in current stake hole to realize the rapid processing at the hole position that collapses in the hole body, improved site operation efficiency greatly, simultaneously owing to do not need whole pouring concrete, also reduced the cost of the hole measures of collapsing.

Description

Drill bit for rapidly repairing wall of pile hole

Technical Field

The utility model relates to a civil engineering pile foundation engineering construction equipment technical field especially relates to a drill bit that is used for quick restoration of stake hole pore wall.

Background

When the rotary drilling bit is used for operation, due to different construction geological conditions, the cave body is often collapsed. For example, as shown in fig. 1, after a mechanical rotary drilling construction hole is dug to a certain depth, the hole wall collapses. The existing solution is to pour concrete or treat the steel casing wall protection into the hole, and when the concrete is filled, the rotary drilling bit is used to dig the drill again after the concrete reaches a certain strength. The method not only increases the working hours of construction, but also wastes a large amount of concrete. The method of adopting the steel casing to protect the wall also greatly increases the construction cost. Therefore, it is desirable for those skilled in the art to improve the efficiency of the pile hole collapse construction process and reduce the process cost.

SUMMERY OF THE UTILITY MODEL

Technical purpose

The method is used for solving the problems of low treatment efficiency and high cost of the cave collapse part when the cave collapse occurs in the construction process of the conventional rotary excavating construction process.

Technical scheme

The drill bit comprises a drill body, wherein the drill body is a cylinder and comprises a first end and a second end, the first end of the drill body is connected with an interface end, the second end of the drill body is a cone, the interface end is in a square cylinder shape, and a plurality of pin holes are formed in the square cylinder.

The stake hole that appears the cavern body collapse generally divide into the dry hole that the hole water content is less and the great wet hole of hole water content, and above-mentioned technical scheme carries out quick prosthetic technological principle to the stake hole and does: when the body of the hole collapses, the first condition is when the construction hole is dry hole, only need through filling 5 to the hole: 5's soil stone mixture later bores the body rotation operation downwards that this technical scheme provided to it is closely knit to extrude the space that soil stone mixture extruded to collapse fast, later can continue to use to dig soon and bore a section of thick bamboo and carry out the operation, has greatly improved the efficiency of construction. The second condition is that when the water content of the construction hole is larger, only concrete exceeding the collapse position needs to be poured into the hole body, and then 5 parts of 2.5 meters are filled into the hole body: 5, then carry out the operation in the hole through the brill body that this technical scheme provided to utilize the earth-rock mixture that later fills to extrude the concrete to the space that collapses fast in, the earth-rock mixture extrudees down to the position that collapses and stops the operation (at this moment the earth-rock mixture is downthehole, the concrete is extruded to the pore wall), makes the concrete fill to pore wall and the position that collapses all around, furthest utilizes the concrete to pore wall and position that collapses, after the concrete reaches certain intensity, can continue to use and dig a drill section of thick bamboo and carry out the operation soon, because the downthehole concrete mixture that is filled, the pore wall that is filled is the concrete, the measure cost of construction treatment has been reduced.

Technical effects

As described above, through the utility model provides a drilling tool comes to extrude the material of current pore wall to realize the pore wall processing of the body in a cave, improved site operation efficiency greatly, simultaneously because downthehole packing be the soil stone mixture, the concrete is crowded to the pore wall by the soil stone mixture, has also reduced the cost of handling.

Detailed Description

Example 1

Referring to fig. 2, a drill 3 for quickly repairing a wall of a pile hole is provided, which includes a drill body 31, wherein the drill body 31 is a cylinder and includes a first end and a second end, the first end of the drill body 31 is connected with a joint end 32, the second end of the drill body is a cone, the joint end 32 is a square cylinder, and a plurality of pin holes are formed in the square cylinder.

Specifically, referring to fig. 3, two pairs of pin holes are vertically arranged in parallel on a first diagonal surface of the square column on which the interface end 32 is located, and a pair of pin holes are vertically arranged in parallel on a second diagonal surface of the square column on which the interface end 32 is located.

Specifically, the peripheries of the square columns are respectively connected with a reinforcing plate 33 connected with the first end of the drill body 31, wherein the reinforcing plate is a triangular steel plate. The reinforcing plate 33 may increase the rigidity of the connection between the drill body 31 and the interface end 32 during rotation.

Specifically, referring to fig. 3, a cone on the first end of the drill body 31 and a cylinder on which the drill body is located are integrally connected, and the drill body 31 and the cone are both hollow structures.

Specifically, the drill body 31 and the interface end 32 are both made of steel.
