Description

Technical Field

[0001] The present invention relates to the technical field of waterproof coating acceptance, and in particular to a waterproof coating thickness detection and acceptance method. Background Art

[0002] The supervision process often involves the construction acceptance of various types of coatings. Rail transit refers to a type of transportation vehicle or transportation system in which operating vehicles need to travel on specific tracks. The national standard "Common Terms and Terminology of Urban Public Transportation" defines urban rail transit as a general term for fast and large-capacity public transportation that is usually powered by electricity and adopts a wheel-rail operation mode. Among them, the more common acceptance of subway station roof waterproofing coatings in rail transit projects is

[0003] In the prior art, the methods for inspecting the coating thickness mostly use the needle measurement method or directly cut the coating and measure it with a vernier caliper. The method of directly cutting the coating and measuring it with a vernier caliper will cause certain damage to the waterproof coating and it needs to be repaired after the inspection. If the repair is not in place, there will be hidden dangers of seepage and leakage, which reduces the waterproof effect. The vernier caliper measurement method is affected by human operation, and the test results have a large error. For this reason, we provide a waterproof coating thickness inspection and acceptance method. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art and to propose a waterproof coating thickness detection and acceptance method. The waterproof coating thickness detection and acceptance method solves the problem that traditional thickness measurement will cause damage to the waterproof coating and needs to be repaired after detection. If the repair is not in place, the hidden danger of water leakage will increase and the waterproof effect will be reduced.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A waterproof coating thickness detection and acceptance method includes a concrete layer, a waterproof coating layer, a galvanized steel plate, a magnetic thickness gauge, a computer terminal and a data processing device, and the specific steps are as follows:

[0007] S1. Input designated data and parameters into the data processing device in advance to create a project;

[0008] S2, data processing equipment calculates the embedded points in the concrete layer;

[0009] S3, bury the galvanized steel plate into the concrete layer according to the pre-buried points;

[0010] S4, make the galvanized steel plate level with the concrete layer, and then apply the waterproof coating layer;

[0011] S5. The magnetic thickness gauge cooperates with the data processing equipment to detect the thickness of the waterproof coating layer according to the pre-buried points;

[0012] S6. Finally, the data processing equipment imports the test results into the computer and makes an acceptance form.

[0013] Preferably, the data processing device includes a GPS positioning module, and the GPS positioning module is used to perform GPS positioning;

[0014] A data storage processing module, which is used to analyze or store input data or collected data;

[0015] A display module, the display module is used to display the collected values;

[0016] A processor, wherein the processor is used to perform information distribution processing;

[0017] A buzzer alarm module, wherein the buzzer alarm module is used to emit a buzzer sound.

[0018] Preferably, S1 specifically includes: creating a project in the data processing device in advance, inputting the area to be measured and the selected type, and the data storage and processing module compares the input data with the relevant specifications stored in the data processing device to display the number of inspection points to be arranged, the inspection thickness range and the data to be accepted.

[0019] Preferably, S2 is specifically to select a GPS positioning origin at the construction site after the initial setting and before the final setting of the cast-in-place structural concrete layer;

[0020] Record the feature points of each corner point in the area to be measured;

[0021] The data storage and processing module gives the recommended detection point burial location coordinates based on the processing results of S1 and S2, and moves through the arrow instructions on the data processing device screen. When the data processing device moves to the recommended point, the buzzer alarm module emits a buzzer prompt.

[0022] Preferably, S3 specifically involves fixing the galvanized steel plate on the concrete layer so that the galvanized steel plate is flush with the concrete layer, and recording the point position in a data processing device.

[0023] Preferably, S5 is specifically to place the probe of the magnetic thickness gauge on the measured point according to the location of the buried point prompted by the data processing device when accepting the construction thickness of the waterproof coating layer, and record the measured thickness value. The data storage processing module in the data processing device analyzes and records the results and prompts on the spot whether they meet the requirements.

[0024] In summary, the present invention performs magnetic thickness measurement on the waterproof coating layer by setting a magnetic thickness gauge in conjunction with a galvanized steel plate. The magnetic thickness measurement principle is adopted without destroying the waterproof coating, thereby solving the problem that traditional thickness measurement may damage the waterproof coating and requires repair after detection. If the repair is not in place, the risk of water leakage will increase, thereby reducing the waterproof effect.

[0025] The present invention solves the problem that the accuracy of traditional thickness measurement results is greatly affected by human operation and the error of the detection results is large, by arranging data processing equipment to cooperate with the magnetic thickness gauge to perform thickness measurement detection, and the measurement result is directly displayed by the data processing equipment.

[0026] In the present invention, the galvanized steel plate is a common material used in large quantities in structural construction. Its scraps can be cut into small pieces for use. The galvanized steel plate has the advantage of being not easy to corrode, and its source is wide, so there will be no shortage of materials.

[0027] The present invention and the waterproof coating thickness detection and acceptance method do not need to cut the waterproof coating layer for measurement, thereby avoiding the link of repairing after detection and solving the problem of time-consuming and labor-intensive repairing after traditional detection.
