Hanging ring pulley type cross section pipe settlement measuring method

Abstract

The invention discloses a hanging ring pulley type cross section pipe settlement measurement method. The method comprises the following steps that a, a groove is dug in the roadbed ground; b, one or more inclinometer pipes are connected end to end to form a cross section pipe, a hole is drilled in a bottom cover of the cross section pipe, and a fixed pulley with a hanging ring is mounted on the bottom cover; c, a traction rope is connected to an inclinometer, arranged in the cross section pipe in a penetrating mode and wound around the fixed pulley, and the inclinometer is placed in the crosssection pipe; d, the cross section pipe is placed in the groove; e, reinforcing steel bars are implanted into roadbed soil to fix the hanging rings; f, the cross section pipe is embedded; and g, the inclinometer is pulled to move in the cross section pipe, and settlement observation is conducted. According to the invention, the trenching work amount is reduced, time and labor are saved, only one special inclinometer tube is buried, materials are saved, economy and environmental protection are realized, the contact area of the traction rope and the special inclinometer tube can be reduced, thepull rope is smooth, the sliding inclinometer can move stably in the special inclinometer tube, and test data are more accurate.

Description

technical field [0001] The invention relates to the technical field of engineering measurement, in particular to a method for measuring the settlement of a suspension ring pulley type transverse section pipe. Background technique [0002] The traditional conventional cross-section settlement tube measurement device uses two special inclinometer tubes and U-shaped joints, and two trenches need to be dug when burying. The excavation volume is large, time-consuming and laborious, and two inclinometer tubes are buried, resulting in waste of materials. The movement resistance of the inclinometer in the inclinometer tube is large, the movement is difficult, and it is easy to cause the inclination angle of the sliding inclinometer servo accelerator to vibrate, resulting in inaccurate test data. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a ...
