[0002] A bored pile is a pile made by drilling a hole and pouring concrete or reinforced concrete. The casing is used in the process of artificially drilling and casting piles. Due to the instability of the soil, it is very difficult to construct a reinforced concrete retaining wall. Therefore, a steel retaining wall is used to protect the bored pile to prevent the hole from collapsing and avoid affecting the construction progress and safety. In the process of placing the casing into the bored pile, the plane position and verticality of the casing after it is lowered are difficult to control, and a guide device is needed to position the steel casing so that the steel casing can be lowered into the bored pile.

[0003] In the current technology, a crisscross frame is mainly used to guide the steel casing. During the bored pile drilling process, a vibrating hammer is driven downward into the steel casing. Due to the long length of the steel casing, it is easy to cause the steel casing to tilt when it is driven into the ground. In addition, the crisscross frame is set on the ground, and it is not easy to adjust the guide stroke according to the size of the steel casing, so the guiding effect is poor.

[0004] Therefore, a construction bored pile casing guide device is needed to solve the problems in the prior art that the steel casing is prone to tilt during installation and guiding, and the guiding device is not easy to adjust the guiding stroke according to demand. Utility Model Content

[0028] This solution has the following working process: when guiding the steel casing, the staff first moves the device to the target area. At this time, the four guide rods 34 are in an open state on the base 1. After the steel casing is inserted into the ground through the through hole 31 and the guide ring 9, the guide rods 34 are made to slide in the first slide groove 32 by rotating the adjusting bolt 37, so that the four guide rods 34 move toward the through hole 31 until the guide wheels 36 on the guide rods 34 contact the steel casing, so that the guide wheels 36 are in contact on all sides of the steel casing, thereby achieving support for the steel casing during installation and guidance.

[0029] By rotating the handwheel 11, the rotation of the handwheel 11 drives the bidirectional threaded rod 10 to rotate, so that the two sliding plates 41 make relative movement on the sliding seat 43, and then the T-bar 48 hinged to the sliding plate 41 is lifted upward, and the upward lifting of the T-bar 48 makes the base 1 lift upward, and the sliding plate 41 makes relative movement to make the guide ring 9 move downward, so as to adjust the guide stroke of the guide device.

[0031] Through the action of the adjustment component 4, the T-bar 48 is lifted to drive the base 1 to be lifted, and the sliding plate 41 moves to drive the guide ring 9 to move downward, thereby increasing the relative distance between the guide component 3 and the ground, and increasing the relative distance between the guide component 3 and the guide ring 9, thereby adjusting the guide stroke of the guide device, and effectively avoiding the problem that the guide stroke of the guide device is not easy to adjust according to demand.

[0034] In summary: when guiding the steel casing, the staff first moves the device to the target area. At this time, the four guide rods 34 are in an open state on the base 1. After the steel casing is inserted into the ground through the through hole 31 and the guide ring 9, the guide rod 34 is made to slide in the first slide groove 32 by rotating the adjusting bolt 37, so that the four guide rods 34 move toward the through hole 31 until the guide wheel 36 on the guide rod 34 contacts the steel casing, so that the guide wheels 36 are in contact on all sides of the steel casing, thereby supporting the steel casing during installation and guiding, so that the steel casing is not easy to tilt under the action of the hydraulic hammer during installation, and effectively avoiding the problem of easy tilting of the steel casing during installation and guiding.

[0035] By turning the hand wheel 11, the rotation of the hand wheel 11 drives the bidirectional threaded rod 10 to rotate, so that the two sliding plates 41 make relative movement on the sliding seat 43, and then the T-bar 48 hinged to the sliding plate 41 is lifted upward, the T-bar 48 is lifted upward, so that the base 1 is lifted upward, and the sliding plate 41 moves so that the guide ring 9 moves downward, so that the guide stroke of the guide device is adjusted, and the problem that the guide stroke of the guide device is not easy to adjust according to the demand is effectively avoided. The T-bar 48 is lifted upward, driving the universal wheel 14 to lift upward, so that the adjustment seat 2 is in contact with the ground, thereby improving the stability of the guide device, and fixing it to the ground by fixing the spikes 17, further improving the stability of the device.
