Embodiment Construction

[0013] Embodiments of the present invention are further described as follows in conjunction with accompanying drawings:

[0014] see figure 1 ——A bolt horizontal inclination measuring instrument made in 3, which includes an angle plate 1 composed of a right-angled side of the semicircle protractor and a straightedge, and two rows of 0 are arranged in both directions on the semicircle protractor of the angle plate 1 —— 180° angle scale. At the center of the semicircle protractor of the angle plate 1, an anchor indicator needle 6 and a vertical indicator needle 5 are sequentially hinged through a damping hinge and a free hinge; The damped rotation on the disk surface indicates the angle; the vertical indicator needle 5 takes the center of the protractor 1 as the axis, and freely rotates on the disk surface of the angle disk 1 to indicate the angle.

[0015] The damping hinge and the free hinge, which pass through the axis bolt 7 at the center of the semicircle protractor, pass...

Abstract

A level dip angle measurer of rock bolt is prepared as forming angle disc by right angle side of semicircumferentor and straight scale, setting two-way and two rows of 0-180 degree angle scale on semicircumferentor of angle disc, hinging rock bolt indication pointer and vertical indication pointer on center of circle at semicircumferentor of angle disc through damping hinge and free hinge to let rock bolt indication pointer indicate angle in damping-rotation way at disc surface of angle disc by utilizing said center of circle as axis and to let vertical indication pointer indicate angle in free-rotation way at disc surface of angle disc .

Description

technical field [0001] The present invention relates to the improvement of construction engineering equipment for deep foundation pits in buildings, in particular to a bolt horizontal inclination measuring instrument and its use method, which indicates a device for measuring the horizontal inclination angle of bolts in deep foundation pit bolt support engineering, especially It can accurately display the horizontal inclination angle of the anchor on the irregular slope. Background technique [0002] At present, with the rapid development of high-rise buildings, underground garages and civil air defense projects, the scale and quantity of deep foundation pit support projects are developing rapidly. Bolt support and soil nail wall are widely used and economical support methods. widely used in. In order to ensure the quality of deep foundation pit support engineering and construction safety, the horizontal inclination angle of the anchor rod in the bolt support engineering is ...
