Description

A long protective tube installation verticality positioning detection device

technical field

The utility model relates to the field of construction of cast-in-place piles of an enclosure structure, in particular to a positioning detection device for the installation verticality of a long protective cylinder.

Background technique

At present, for the construction of bored cast-in-place piles under adverse conditions such as deep water or silt, long guards are often used to assist in the formation of holes for the cast-in-place piles. In the process of pulling and installation, the precise positioning of its verticality directly affects the pile quality of bored piles.

The conventional method of positioning the verticality of the long casing adopts the method of continuously hoisting the measuring hammer to manually measure the deviation of the casing and adjusting it gradually during the process of lowering the steel casing. The problem.

SUMMARY OF THE INVENTION

In order to solve the problems of complicated procedures, large errors and low efficiency in measuring and setting the verticality of the conventional steel protective tube, the utility model provides a verticality positioning detection device for the installation of a long protective tube.

The technical scheme solved by the method includes a steel protective tube, a hoop is installed on the side wall of the steel protective tube, four fixing blocks are evenly distributed on the circumference of the hoop, and each fixed block is fixed with a support perpendicular to the side wall of the steel protective tube. The outer ends of the rod and the support rod are set with vertical lines. The lengths of the four vertical lines are equal. An electronic laser collimator is suspended at the lower end of the vertical lines. The cross cursor of the laser collimator is placed on the side wall of the steel casing.

The length of the support rod is greater than 1.5 times the length of the vertical line.

The said holding hoop is composed of two semicircles, the diameter is the same as the outer diameter of the steel protective cylinder, and the holding hoop is connected and fastened by bolts.

Four vertical scales are arranged on the side wall of the steel protective tube, and each laser vertical collimator is aligned with one scale.

The utility model realizes fast checking and fast positioning by observing with the naked eye and determining whether the steel protective tube is deflected and the deflecting direction.

FIG. 2 is a front view of the present utility model when the steel casing is deflected.

Detailed ways

In conjunction with the accompanying drawings, the specific embodiments of the present utility model are further described below.

The utility model comprises a steel protective cylinder 1, a hoop 2 is installed on the side wall of the steel protective cylinder 1, the position of the hoop 2 can be adjusted on the steel protective cylinder 1, and four fixing blocks 3 are evenly distributed on the circumference of the hoop 2, Each fixing block 3 is fixed with a support rod 4 which is perpendicular to the side wall of the steel casing 1. The outer end of the support rod 4 is provided with a vertical line 5. The lengths of the four vertical lines 5 are equal. The lower end of the vertical line 5 is suspended with a Electronic laser collimator 6, the cross cursor of the laser collimator 6 is placed on the side wall of the steel shield 1, when the steel shield 1 is vertical, the cross cursors of the four laser collimators 6 are at the same height, and the steel shield 1 When deflected, the cross cursors of the four laser plummets 6 will also produce height differences.

The length of the support rod 4 is greater than 1.5 times the length of the vertical line 5 , so as to prevent the electronic laser collimator 6 from swinging and touching the steel protective tube 1 during the setting of the steel protective tube 1 .

In order to facilitate the installation of the hoop 2 and the steel casing 1, the hoop 2 consists of two semicircles, the diameter of which is the same as the outer diameter of the steel casing 1, and the hoop 2 is fastened by bolts for easy disassembly.

Four vertical scales 7 are arranged on the side wall of the steel casing 1, and each laser vertical collimator 6 is aligned with a scale 7, so that the height corresponding to the cross cursor can be quickly read.

When setting the steel protective tube 1, if the steel protective tube 1 is in a vertical state, the scales corresponding to the cross cursors of the four laser collimators 6 are the same. If the steel protective tube 1 is deflected, the four laser vertical The scale corresponding to the cross cursor of the collimator 6 will change. Specifically, which side of the steel guard 1 is higher, the scale corresponding to the cross cursor of the laser vertical collimator 6 on that side will move up, so as to judge and adjust The verticality of the steel casing 1.

As the steel casing 1 is driven in, the position of the hoop 2 is adjusted in a timely manner so that the laser collimator 6 is always located above the water surface or the mud surface.

The utility model avoids the time-consuming and labor-intensive problems of repeated measurement of the verticality correction of the traditional steel protective tube, and can effectively solve the problems of cumbersome procedures, large errors and low efficiency in the measurement and setting of the verticality of the conventional steel protective tube 1, and realizes rapid verification and fast verification. position.
