Problems solved by technology

[0002] At present, the existing detection methods for the degree of separation between layers of CRTS III ballastless track structure are very limited. The existence of dense steel bars inside the track slab, the presence of impurities such as internal moisture, stripped concrete residue, and mud make it almost impossible for the above test methods to effectively measure the degree of voiding from the joint
(2) Destructive testing: core sampling is required on site. Since the width distribution of the separation gap cannot be uniform, this method not only has a large workload, but also cannot accurately give effective evaluation measurements.
[0003] Using the method of injecting liquid to fill the gap between the layers of the track structure can measure the void degree relatively simply, but it is easy to make mistakes during the measurement, resulting in re-measurement, which is time-consuming and labor-intensive

Embodiment 1

[0031] This embodiment provides a fast detection method for the degree of voiding from the seam, please refer to figure 1 , this rapid detection method for the degree of voiding of the gap is used to detect the degree of voiding of the gap between layers of the track structure, including steps:

[0032] First measure the width b of the seam, where the width of the seam is the gap of the small span of the seam, in the present embodiment, use a feeler gauge to measure the width of the seam;

[0033] Along the length direction of the separation seam, the liquid injection pipe is buried inside the separation seam, and the separation seam is sealed along the length direction of the separation seam, and an observation port is also arranged on the separation seam;

[0034] The perfusion is carried out inside the separation gap, and the perfusion can directly use water. After the liquid flows out of the observation port, the perfusion is stopped, and the volume V of the perfused liqui...

Embodiment 2

[0045] This embodiment provides a liquid injection device 001, please refer to figure 1 , this liquid injection device 001 is used to detect the degree of voiding of the rail gap, and includes a liquid injection machine body 010 and a monitoring part 030 .

[0046] The liquid injection machine body 010 includes a liquid storage part 100 and a liquid outlet part 200. There is a liquid storage space for liquid storage in the liquid storage part 100. In this embodiment, the liquid storage part 100 is used to store tap water. In other embodiments In the process, liquids of different viscosities can also be stored according to different site conditions to accurately measure the track separation in different situations. The liquid storage part 100 is made of a transparent plastic barrel, and a water injection hole is provided on the liquid storage part 100, and water is injected into the liquid storage space through the water injection hole. Since the liquid storage part 100 is made...

Abstract

The invention provides a rapid detection method for disengagement degree of a gap and a liquid injection device, belonging to the field of steel rail detection equipment. The rapid detection method for the disengagement degree of the gap is used for detecting the disengagement degree of a gap between track structural layers and comprises the following steps: measuring the width b of the gap; alongthe length direction of the gap, embedding a liquid injection pipe into the interior of the gap, and sealing the gap along the length direction of the gap, wherein an observation hole is also arranged above the gap; filling the interior of the gap, after liquid flows out the observation hole, stopping filling, and metering volume V of the liquid injected into the gap; calculating the area S1 of the gap according to a formula that S1=V / b; and calculating the disengagement degree N of the gap by virtue of the area S of a track board according to a formula that N=S1 / S*100%. By adopting the rapiddetection method for the disengagement degree of the gap and the liquid injection device, detection accuracy can be improved, and the cost of manpower and material resources can be reduced.

Description

technical field [0001] The invention relates to the field of rail detection equipment, in particular to a method for quickly detecting the degree of gap-free space. Background technique [0002] At present, the existing detection methods for the degree of separation between layers of CRTS III ballastless track structure are very limited. The existence of dense steel bars inside the track slab, the presence of impurities such as internal moisture, stripped concrete residue, and mud make it almost impossible for the above test methods to effectively measure the degree of voiding from the joint. (2) Destructive testing: core sampling is required on site. Since the width distribution of the separation gap cannot be uniform, this method not only has a large workload, but also cannot accurately give effective evaluation measurements. [0003] Using the method of injecting liquid to fill the gap between the layers of the track structure can measure the void degree relatively simpl...
