[0001] The utility model relates to the technical field of casing installation, in particular to a precise installation and positioning device for pile foundation full steel casing wall. Background Art

[0002] With the rapid development of urban subway projects, the rapid support method of bored cast-in-place piles plus water-stop curtains is often used in the construction of subway station retaining structures. The bored cast-in-place piles are drilled by a drill bit, and the drilling slag is carried out by mud circulation to form a hole. Then a full steel casing is installed to protect the excavated hole and prevent collapse. Then a steel cage is installed and concrete is poured to form a pile foundation. The steel casing is a circular barrel with empty ends made of iron sheets according to the size of the pile hole.

[0003] The steel casing is installed by mechanical pressing. Since the bored piles in subway stations are mostly tens of meters deep, during the installation of the all-steel casing, the traditional method requires technicians to stand in front of the all-steel casing and manually direct the vertical driving of the all-steel casing to prevent the all-steel casing from tilting during the mechanical pressing process, which would affect the quality of pile foundation formation. During this process, technicians need to observe and calibrate at multiple positions to determine the horizontal and vertical inclination of the all-steel casing, which requires a high level of construction experience and technical level from the technicians. In addition, the mechanical swing arm and strong vibration during the mechanical pressing process pose a threat to the personal safety of the technicians. Utility Model Content

DETAILED DESCRIPTION

[0023] The specific implementation of this embodiment is described below in conjunction with the accompanying drawings.

[0024] Refer to Figures 1 and 2 Figure 2 A precise installation and positioning device for a pile foundation all-steel cylinder wall protection comprises a positioning device 2 consisting of a dial casing 2-3, a magnetic connecting plate 2-1 and a leveling laser emitter 2-2. A casing top surface 4-1 is arranged above the dial casing 2-3, a leveling laser emitter 2-2 is installed at the center of the casing top surface 4-1, a connecting cover 3-1 is arranged on the leveling laser emitter 2-2, the connecting cover 3-1 is fixed on the casing top surface 4-1, a floating plate 3-2 is arranged in the connecting cover 3-1 through liquid floating, a laser emitter 3-3 is installed on the lower side of the floating plate 3-2, and the dial casing 2-3 is adsorbed on the side wall of the steel casing 1 through the magnetic connecting plate 2-1.

[0025] 4, the scale sleeve 2-3 is cylindrical, and a sleeve bottom scale sleeve 4-4 is arranged at the bottom of the scale sleeve 2-3, and an x-axis marking line 4-2 and a y-axis marking line 4-3 are arranged perpendicularly to each other on the sleeve bottom scale sleeve 4-4.

[0026] The scale plate 4-4 on the bottom of the casing is made of transparent photosensitive material, and the connecting cover 3-1 is a spherical shell. The connecting cover 3-1 is made of transparent photosensitive material to ensure that the laser can be emitted from the scale plate 4-4 on the bottom of the casing and the connecting cover 3-1.

[0027] Referring to Figure Attachment 3, the floating plate 3-2 is set at the horizontal middle position of the connecting cover 3-1, the laser transmitter 3-3 is vertically installed on the lower side of the floating plate 3-2, and the level bubble 3-2 is placed at the horizontal middle position of the connecting cover 3-2, which has an automatic horizontal leveling function, and the laser transmitter 3-3 is connected below it. The laser transmitter 3-3 can emit lasers and use the laser phase ranging principle to realize the laser ranging function with an accuracy of millimeters. When in use, the laser transmitter 3-3 can measure the distance from the top of the outer wall of the full steel cylinder protective wall 1 to the ground. Since the length l of the full steel cylinder protective wall 1 is known, the installation depth of the full steel cylinder protective wall 1 is ld.

[0028] The magnetic connecting plate 2-1 is an arc-shaped plate, and the inner wall of the magnetic connecting plate 2-1 is directly lowered to the same diameter as the outer wall of the steel casing 1. The magnetic connecting plate 2-1 is a strong electromagnetic induction plate. After power is turned on, the side has a strong magnetic field, so that the joint and the full steel casing 1 are closely adsorbed, and the device is suspended on the top of the outer wall of the full steel casing 1. After power is turned off, the magnetism disappears, and the device is recovered.

[0029] When the steel casing 1 is perpendicular to the ground, the axis of the laser emitter 3-3 is parallel to the axis of the steel casing 1, and the leveling laser emitter 2-2 can ensure that the laser emitter 3-3 is in a horizontal leveling state through the automatic leveling function of the level bubble 3-2.

[0030] The laser transmitter 3-3 is connected to the Bluetooth transmitter. The installation depth of the full steel tube wall protection 1, its horizontal longitudinal inclination angle and lateral inclination angle obtained by the device can be transmitted to the operator and the command technician's display via Bluetooth, thereby realizing the visualization and precise guidance of the installation process of the full steel tube wall protection 1.

[0031] Detection principle:

[0032] When the laser emitted by the laser emitter 3-3 passes through the scale plate 4-4 on the bottom surface of the casing, the x and y coordinates of the laser point can be sensed. When the full steel cylinder protective wall 1 is vertical, the laser passes through the origin of the cross coordinate system (x=0, y=0); when the full steel cylinder protective wall 1 is tilted, the laser passes through the quadrant area of ​​the cross coordinate system (x≠0, y≠0). Since the height h from the laser emitter 3-3 to the scale plate 4-4 on the bottom surface of the casing is known, when the full steel cylinder protective wall 1 is tilted, the horizontal longitudinal tilt angle α (tanα=x / h, tanβ=y / h) and the lateral tilt angle β of the full steel cylinder protective wall 1 can be calculated through the right triangle conversion relationship, and it can be accurately judged whether the full steel cylinder protective wall 1 is tilted forward or backward, left or right during installation.

[0033] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
