Embodiment Construction

[0025] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0026] refer to figure 1 , an embodiment of the method for the calibration model of the manufacturing pipeline grouting quality detection instrument of the present invention, it comprises the steps:

[0027] Step a. Build a support platform. In this embodiment, a cuboid concrete support platform with a length of 20 m, a width of 0.5 m, and a height of 0.1 m is built. Preferably, the site is cleared prior to building the platform. The surface of the support platform with the largest area is in contact with the ground, and the direction of the height is the direction in which it protrudes from the ground.

[0028] Step b. Set the support frame on the support platform, and set the indicator mark on the support platform. In this embodiment, the supporting frame set on the supporting platform is a reinforced skeleton. After the reinforcement skeleton is...

Abstract

On one hand, the invention relates to a method for manufacturing a calibration model of a pipeline grouting quality detection instrument. The method comprises the steps: a supporting platform is built, a supporting framework is arranged on the supporting platform, and indication marks are arranged on the supporting platform; corrugated pipes are arranged in the supporting framework; corrugated pipe sections each provided with an opening are arranged; the corrugated pipes are fixed on the supporting framework; steel strands penetrate through each corrugated pipe; two end parts of each corrugated pipe are blocked off, and connection parts of the pipe sections with the opening and corrugated pipe sections are blocked off; grouting holes are equidistantly arranged in the pipe wall of each corrugated pipe; cement slurry is grouted into the grouting holes until the corrugated pipe sections with the grouting holes are filled with the cement slurry; a sleeve is sleeved on the peripheral wall of each connection part, and the openings are sealed; and a mold is mounted, and concrete is poured to form the calibration model. On the other hand, the invention relates to the calibration model manufactured by the method. The method can be used for precise manufacturing of 100% empty slurry sections in the corrugated pipes. A test is carried out by using the model manufactured by the method, and an accurate defect judging criterion can be worked out.

Description

technical field [0001] The invention relates to a method for manufacturing a calibration model of a pipeline grouting quality detection instrument and the calibration model manufactured by the method. Background technique [0002] With the development of highway and bridge construction in our country, prestressed bridges have taken a dominant position in bridge construction in our country and are widely used in many important bridge construction projects. In order to ensure that the prestressed steel strands play a long-term role in the use of the bridge and meet the design requirements, the grouting quality of the prestressed tunnel is an important factor. If the grouting in the prestressed channel is not dense, the steel strands in the channel are prone to corrosion, which will affect the durability and safety of the bridge and affect the service life of the bridge. Therefore, it is of great significance to objectively evaluate the quality of the structure by using advanc...
