Embodiment 1

[0070] The digital display high-precision mud viscosity tester of this embodiment, such as figure 1 As shown, it includes a support unit 1 , a mixing unit 2 , a funnel unit 3 and a measuring unit 4 .

[0071] The support unit 1 of this embodiment includes a triangular base 10 and a support rod 11 , wherein the triangular base 10 is a triangular plate-like structure, the three corners of the triangular base 10 of this embodiment are movable triangular blocks 100 , and the middle part is a fixed triangular block 100 . base block 101, such as figure 2 As shown, the three movable triangular blocks 100 are respectively hinged with the three sides of the fixed base block 101, so that the movable triangular blocks 100 can rotate around the hinges. When the tester is not in use, the three movable triangular blocks 100 can be stowed as image 3 In the state shown, the space occupation is reduced and the portability is convenient. An installation hole 102 is opened in the middle of th...

Embodiment 2

[0083] The high-precision mud viscosity test method of the present embodiment, based on the high-precision mud viscosity tester of Embodiment 1, includes the following steps:

[0084] 1. Tester assembly

[0085] Assemble the triangular base 10 and splicing to complete the support rod 11, then connect the support rod 11 with the triangular base 10, fix the Marsh funnel 30 on the right side of the support rod 11 through the bracket, and fix the mixing container 21 on the support rod through the bracket On the left side of 11, the mixer 20 is fixed directly above the mixing container 21 through the bracket, one end of the plastic hose 22 is connected to the bottom of the mixing container 21, and the other end is placed above the Marsh funnel 30 through the fixed pipe clamp 31;

[0086] Second, configure the mud

[0087] Clamp the hose 22 with a clamp, turn off the rotary switch 33 at the bottom of the Marsh funnel 30, place the weighed air-dried clay and bentonite in the mixing ...

Embodiment 3

[0095] In this embodiment, the wall-protecting mud is configured with different water contents, and the high-precision mud viscosity tester of Embodiment 1 is used to test the mud viscosity.

[0096] Among them, the retaining wall mud is made up of air-dried clay, bentonite, and water with a fixed volume.

[0097] Table 1 and Table 2 show the mix ratio of wall protection mud and test time results under different water contents.

[0098] Table I

[0099]

[0100] Table II

[0101]

[0102] T in the table is T 1 , T 2 , T 3 The average of three numbers.

[0103] Tables 1 and 2 are the statistical results according to the test experiments. It can be seen that for the mud with a water content of less than or equal to 350%, the results measured by the Martens funnel 30 of structure type 1 are more accurate than the traditional stopwatch method. Great improvement, for the mud with water content greater than 400%, the Martens funnel 30 of structure type II increases its v...

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and more particularly relates to a digital display high-precision mud viscosity tester and a test method thereof. Background technique [0002] In the application of geotechnical engineering, in order to prevent the hole from collapsing when drilling in the soil layer, the method of mud wall protection is commonly used. The mud wall protection method is an effective and economical method. The quality of wall protection mud has three requirements, namely viscosity, specific gravity, Sand content; the viscosity of the mud is generally expressed by the time it takes to flow through a 500ml Martens funnel. The time required for normal water to flow through a 500ml Martens funnel is 15s. The specification TB10203-2002 for the mud viscosity of the wall protection is as follows: the general formation is 16 ~22s, 19-28 seconds for loose and easily slumpable formations, and the specification als...
