Embodiment 1

[0025] See attached Figure 1-3 , the method proceeds in the following steps:

[0026] 1. Assembling the device: first, put the expansion device 3 into the soil squeezing device 2 to form a specific anchoring section, then connect the anchoring section with the force transmission mechanism 1, connect the expansion control mechanism 4 with the inflatable tube 5, and finally connect the transmission The force mechanism 1 is connected with the anchor plate and fixed with nuts;

[0027] 2. The connection of the measuring line: the measuring line 6 marked with the scale on the outer surface runs through the soil squeezing device 2 along the inflatable tube 5, and passes through the outside of the expansion device 3. The radian of the steel sheet is consistent, and the end of the measuring line 6 is glued to the arc-shaped steel conduit 7 welded on the inner side of the bottom of the soil squeezing device 2;

[0028] 3. Actual measurement: Send the assembled expansion control anch...

Abstract

The invention provides a method for measuring the diameter of an expanded hole of an expansion control anchor rod. The method is carried out according to the following steps that 1, devices are assembled; 2, measuring lines are connected; 3, actual measuring is conducted; and 4, data recording is conducted. According to the method for measuring the diameter of the expanded hole of the expansion control anchor rod, the measuring lines with scales being marked on the surfaces and the expansion control anchor rod are combined for common use, and change of the diameter of the expanded hole in thewhole expansion process can be measured without using complex devices such as a sensor in a traditional method; and meanwhile, calipers in the traditional method are not required to be used for measuring the final hole diameter, while the calipers are replaced with the scales on the carbon fiber measuring lines, and the variable quantity of the diameter of the expanded hole is converted accordingto the relationship between the circumference and the diameter of a circle.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a method for measuring the diameter of expansion-controlled anchor rod reaming. Background technique [0002] At present, the method of measuring the diameter of the drilled hole and the drilled hole after reaming in engineering practice is mainly to use the combination of sensing device and signal processing system to measure the diameter of the hole after forming. This method has complex operation and The disadvantage of high cost, and it is mainly used to measure the diameter of the final hole. Therefore, it is not used in many practical applications, and this method is not suitable for the measurement of the expansion diameter of the expansion control anchor. [0003] There are many unclear factors in the research of expansion-controlled anchor rods, such as the change of reaming diameter under the action of expansion-controlled anchor rods. At present, no re...
