Embodiment Construction

[0067] A hydraulic measurement and control method, comprising the steps of:

[0068] Step 1: Standard Concrete Block Test

[0069] Use standard concrete block to test, described standard concrete block refers to the standard concrete cube whose length, width and height are 1 meter. During the test, 25 points are taken on the concrete block to apply pressure. These 25 points are except the bottom surface, in addition Five points are taken on each of the five surfaces, and the pressure points on each surface are selected according to the following principles: one point at each corner and one point at the center.

[0070] The test was carried out in two parts, the first time for the top face only and the second time for all five faces simultaneously.

[0071] In the first test, only for the five points on the top surface, when the pressure is applied, record the pressure result and test temperature, where the test temperature t 顶 The temperature range is -30°C~80°C, and the tes...

Abstract

The invention belongs to a measurement and control method, in particular to a hydraulic measurement and control method. It includes: step 1: standard concrete block test; test the top surface and four sides respectively, and the test is carried out at different temperatures; step 2: data merging; data merging of the top surface and sides respectively; step 3: pressure temperature Curve fitting; respectively perform pressure-temperature curve fitting on the top and side surfaces; step 4: curve fitting of pressure difference and temperature difference; respectively perform pressure and temperature difference curve fitting on the top and side surfaces; step 5: test; The concrete blocks undergoing pressure testing are subjected to pressure testing. In addition to recording the pressure value, the temperature during the pressure test is also recorded; step 6 is corrected according to whether the test in step 5 is tested at normal temperature or under a specific constant temperature condition, respectively. fix. The remarkable effect of the invention is that the cost of building a constant temperature laboratory is saved, the test result is fast and convenient, and the cost is greatly reduced.

Description

technical field [0001] The invention belongs to a measurement and control method, in particular to a hydraulic measurement and control method. Background technique [0002] Concrete for construction needs to be tested in advance when it is actually used. The test is mainly for the compressive strength and consistency of the concrete block. According to the test results, ensure that the selected concrete meets the actual use requirements. [0003] Existing test methods mainly include rebound method, ultrasonic rebound comprehensive method, pull-out method, core drilling method, etc. Among them, pull-out method and core drilling method are destructive test methods, which are only used in special occasions; rebound method 1. The ultrasonic rebound comprehensive method is a non-destructive test method, which is relatively widely used. [0004] In the actual test, the test work is generally carried out on the standard size concrete blocks provided by the manufacturer. When usi...
