Description of the invention (1) [Technology to which the invention belongs The invention has a design parameter related to model irrigation. [Prior technology] Currently used in the process of grouting, as shown in Figure 1, pump, grouting tube The results of the design of the local conditions are not outstanding, so the type grouting test, the penetration number (such as the parameters of the grouting material hole spacing, etc.) in order to improve the existing indoor mold test on the spot, and the regional static state mold. The test is to compact two identical tests. "Good, good" and different test of the permeability coefficient of the split body of the test body to achieve the stress changes in the depth of the infiltration layer, and the field of operation], two types of grouting test body simulation system and method, especially for simulating in situ grouting operations to analyze and modify The simulation system of the grouting test specimens for the successful grouting. T 3 filling points such as filling, deep excavation, sewers, and MRTs are all located on the ground floor. The required on-site grouting settings include polymer mixers, mixers, and slurry conveying devices. 'Because the volume of each body is quite large, and If it is not equipped and the relevant grouting operation parameters are adjusted in 1 week, it will cause the grouting to enter = in-situ filling must be performed in the laboratory, and the mold = the result of the grouting test to modify the relevant design parameters #packing liquid ratio, grouting The volume and grouting pressure and grouting are based on the results of the indoor test to give feedback to the local grouting operation and the purpose of the successful grouting. The proposed test method can be divided into groundwater flow and stationary two-blade type I gas. The scale is small-scale and large-scale tests. Take the ground-scale test as an example. The small-scale test is shown in Figure 2. The sand grouting method is used, and penetration is used. The rod is compacted to prepare one of them to remain intact, and the other to grout and change 5 layers to send 9 measurement points. This test is mainly used to judge the test condition / brother.

The large-scale test shown in Figure 3 is mainly to set the filter material (gravel) on the bottom of the simulation barrel of the grouting sample, and then to the body (sand or soil). The top of the barrel is provided with a rubber layer to fill the pressure, and the scale test after the grouting tube has been filled can be penetrated through the grouting during the pressurization equipment. Moreover, the improvement range of the grouting and the shape of the sample facing different pores can be used to fill the slurry. Both the distribution ratio and the flow rate must be checked. It is impossible to detect the pore water squeezed out of the sample during the grouting into the water tank, and the in-place grouting operation still has a parameter relationship that makes the grouting mechanism. [Abstract] The main purpose of the present invention is to Existence 'The present invention provides a complete grouting test simulation, thereby establishing a grouting body simulation system with increased functionality, including a grouting barrel and a sand reduction unit. After the sand reduction unit is filled at equal intervals to the public rack, it passes through the pressure barrel. Fill the filter material with the grout tube inserted from the excavated sample. The simulation side enters the simulation barrel to saturate the sample, and then pressurize or compact it. The formula provides pore water to cover the gap between the test specimens. This is to simulate the stress conditions in the deep layer. To understand that the grouted specimens can be dug out, strength and permeability after the actual test. It is included in the parameter design, but the flow of the conventional simulation test can at best only be obtained from the overall flow during grouting. Therefore, the related design grouting pressure and grouting flow are not enough in the future. In order to solve the above-mentioned shortcomings, to avoid the lack of unrolling and present a better grouting mechanism in the indoor moulding operation, the grouting system and its method are mainly achieved through the simulation system unit, pressure barrel, and a flow calculation to reduce sand to the simulation barrel. And the simulation barrel placed the test body 200303381 V.

Description of the invention (5) (B) Preparation of local test specimens: Since the present invention uses the dry down casting method to cast the test specimens, the test specimens are first subjected to a drying process. During the process, pay attention to the existence of the test specimens. Debris must be removed first. The temperature and time of drying the soil sample depends on the type of soil. The principle is to ensure that the soil sample is dry. At this time, after the drying of the sample is completed, the pouring operation is started. Place the container 2 1 and carry the container 2 1 through the moving body 2 2 to the bottom of the grouting bucket 1 0 to start the test body pouring (as shown in Figure 5). Since the container 2 1 has a The sand-falling pipe 2 1 1 extending into the grouting bucket 10, and the sand-falling pipe 2 1 1 is provided with a distance element 2 1 2 at a certain height from the test specimen's sand-reduction height, so that the distance element 2 1 2 can ensure The gravity of all specimens is stable during pouring, that is to say, the pores of the specimen can be kept constant, and no loosening and loosening will occur. Pouring with a spiral concentric trajectory can maintain the flat surface of the specimen. However, when the test specimen is sand-reduced to the measurement depth, the sand-fall operation is temporarily stopped. (C) Place the grouting frame 14 on the inner lining body 12 and make the grouting tube 1 4 1 of the grouting frame 14 4 at the measuring depth (as shown in Figure 6). (D) Continue the test body pouring operation, and record the total pouring time, the total test body pouring amount and calculate the test body porosity ratio after the test body pouring is completed. The so-called pouring completion refers to the test body's sand dropping height to the inner lining body 1 2 The top is the same height. It should be noted that when the pouring operation reaches a certain height, in order to avoid the sand reduction pipe 2 1 1 from interfering with the pouring operation, it can be considered to replace the short sand reduction pipe 2 11 to continue pouring, as shown in Figure 7. Show. (E) Perform the sample saturation operation. As shown in Figure 8, through the water pressure bucket 31, slowly inject water from the water inlet 16 of the grouting bucket 10, so that the sample is saturated with water and the pore air is discharged, and the saturation is recorded.
