Problems solved by technology

In the stage of laboratory research, we tested the water permeability of the test block with reference to industry standards, but found many problems, such as directly using tap water to supply water, the water pressure is not easy to stabilize, which affects the accuracy of the data; using a steel ruler to measure the water level difference , due to the fluctuation of the water level, it is not easy to measure accurately; after the measurement is completed, the water flowing out of the overflow port of the cylinder and the overflow port of the sink is poured out directly. If the test block has large pores or a large number, a lot of water resources will be wasted, etc.

[0096] like figure 1 , 2 , Shown in 3, a kind of multifunctional linkage device that collects time-divided sampling and water permeability test as one, the main components are water supply channel 1; cylinder overflow port 2; water cylinder 3; overflow tank 4; tank overflow Orifice 5; sample bracket 6; sample 7; flow meter 8; water level difference 9; electronic thermometer 10; Control valve 15; second drainage control valve 16; third drainage control valve 17; fourth drainage control valve 18; drainage bucket 19; drainage bucket can control water discharge valve 20; working bucket 21; propeller 22; 23; water pump 24; water pump electric control 25; propeller electric control 26; power switch 27; water supply conduit 28; first drainage conduit 29; second drainage conduit 30; workbench B31; These components belong to two parts, named Apparatus A and Apparatus B respectively.

[0097] The shape and connection method of each part of device A are as follows: The overflow tank 4...

Embodiment 2

[0101] Sewage time-sharing sampling and water permeability test are carried out at the same time, simulating the environment of sample 7 filtering sewage for a long time. First close the working bucket to control the drain valve 23, put 10 parts of quality impurities and 90 parts of quality clear water into the working bucket according to a certain ratio, turn on the power, turn on the power switch 27, adjust the propeller electric control 26, make the propeller 22 with a certain Rotate at a certain speed to fully mix the sewage in the working bucket 21. At this time, the concentration of the sewage in the bucket remains constant at 10%. Closing the overflow tank can control the drain valve 13, the third drain control valve 17 and the fourth drain control valve 18. The first drain control valve 15 and the second drain control valve 16 are opened, and the water discharged from the cylinder overflow port 2 and the tank overflow port 5 in the device A flows to the working bucket ...

Embodiment 3

[0127] A method of using a multi-functional linkage device that integrates time-collecting sewage water sampling and permeability coefficient testing:

[0128] (1) Single measurement of permeability coefficient. The test water quality is clear water, and the instruments used include device A, water pump 24 and working bucket 21. The specific operation steps are as follows:

[0129] A. Fill most of the bucket of water into the working bucket 21, the temperature is controlled at 20±3°C, and the water discharge valve 23 can be controlled by closing the working bucket. Prepare a stopwatch with an accuracy of 1s. Prepare a vernier caliper with a division value of 1mm and a range greater than 100mm. Prepare three cylinders with a diameter D of 100 mm and a thickness L of 50 mm as samples and mark them.

[0130] B. Use a vernier caliper to measure the diameter D and thickness L of the cylindrical sample, measure 3 times respectively, and take the average value. The result is accur...

Abstract

The invention relates to the technical field of civil engineering materials testing, in particular to a multifunctional linkage device integrating sewage time-sharing sampling and permeation coefficient testing and a working method of the multifunctional linkage device. The device mainly comprises two parts, wherein a first part is a device A and mainly comprises a power supply channel, a cylindrical overflow port, a water cylinder, an overflow water tank, a water tank overflow port, a test sample bracket, a test sample, a dial gauge, a sewage sampling pipe, a high-precision flow gauge, an electronic thermometer, a working table I and the like; a second part is a device B and mainly comprises a working water bucket, a water draining bucket, a propeller, a water pump, a power switch, a water pump electronic control assembly, a propeller electronic control assembly, a guide rod rotation driver, a working table II and the like; the device A and the device B are connected through one water supply guide pipe and two water draining guide pipes, and accordingly, the multifunctional linkage device is formed. Therefore, the condition of sewage permeation of a porous pavement in a real environment can be simulated, samples of sewage filtered by the test sample are obtained at different moments, the permeation coefficient of the test sample is tested simultaneously, the water resource is recycled, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of civil engineering material testing, in particular to a time-divided sampling and permeability coefficient joint testing technology of permeable cement concrete sewage. Background technique [0002] At present, there is no national standard in the field of permeable cement concrete pavement, and generally refer to the industry standards compiled in recent years and the local standards of Beijing. The water permeability coefficient is an important index to measure the water permeability of pervious concrete. The industry standard and the local standard respectively give two different test methods. "Technical Regulations for Permeable Cement Concrete Pavement" (CJJ / T 135-2009) is an industry standard in this field. In Appendix A, the test device, operation steps and calculation formula for measuring the water permeability coefficient by the constant water head method are given. This method It is suitable fo...
