Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and in particular to a horizontal pushing test device based on grouting mixed soil. Background Technology

[0002] Miscellaneous fill is composed of a mixture of construction waste, industrial waste, and domestic garbage, and has the following characteristics: complex composition: containing bricks, concrete fragments, plastics, organic matter, etc., with significant differences in physical and mechanical properties; heterogeneity: the density, strength, and compressibility vary significantly in different areas; loose structure: in its natural state, it has large pores and is prone to uneven settlement or shear failure. Therefore, during engineering construction, it is necessary to determine the shear strength of the miscellaneous fill in the area so that reinforcement can be carried out according to the actual situation, thereby ensuring the stability of the corresponding engineering structure.

[0003] Existing devices for measuring the shear strength of miscellaneous fill have the following problems: the side baffles are prone to tilting, the position of the jacks is not standard, thus affecting the test results, and users cannot intuitively obtain the displacement. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0047] Example 1:

[0048] like Figure 1-3 As shown in the figure, this application discloses a grouting fill soil pushing test device for realizing soil pushing test. In use, the soil layers on both sides are first separated by the limiting plate of this application, and then the test soil is pushed and sheared.

[0049] like Figure 1 As shown, the specific structure of this application includes:

[0050] Three limiting plates 1 are connected end to end to form a cavity 101 with one side open and vertically connected. During subsequent tests, the corresponding test soil is placed inside the cavity 101. When using the three limiting plates 1, they are first welded to form the cavity. In order to ensure the accuracy of the test results, this application can also apply a layer of grease to the inside of the limiting plates 1.

[0051] The force plate 2 is disposed on the opening side of the chamber 101. The force plate 2 is designed to facilitate the application of pressure, that is, by applying pressure to the force plate 2, the stability test of the test soil is completed.

[0052] Jack 3 is horizontally set, and the output end of jack 3 is engaged with the force plate 2. Jack 3 is used to provide pressure, and its specific model can be QF50T-20b.

[0053] The pad 4 is installed on the side of the jack 3 away from the force plate 2. The pad 4 is mainly used to limit the end of the jack 3, thereby ensuring the stability of the jack 3 during operation.

[0054] An adjustable support plate 5 is set at the bottom of the jack 3. The adjustable support plate 5 is mainly used to provide support, and also has a certain adjustment function, that is, to ensure the stability of the jack 3, and also to ensure that the output end of the jack 3 is located at 1 / 2 of the width and 1 / 3 of the height of the force plate, thereby ensuring the accuracy of the measurement results.

[0055] The side pull assembly 6 is disposed on the outside of the two opposite limiting plates 1. The side pull assembly 6 is mainly used to ensure the stability of the position of the two opposite limiting plates and to prevent the two limiting plates 1 from shifting during the test.

[0056] In one embodiment, the side pull assembly 6 includes:

[0057] Two limiting posts 601 are connected and disposed on the outside of the limiting plate 1. The limiting posts 601 are welded to the outside of the limiting plate 1. Specifically, a limiting post 601 is welded to the outside of each of the two limiting plates 1. Then, by tightening and locking the two limiting posts 601, the stability of the limiting plates 1 in relative positions during operation is ensured.

[0058] The locking member 602 is connected to the two limiting posts 601 at both ends. The locking member 602 is mainly used to lock the limiting posts 601 and ensure the distance between the two limiting posts 601.

[0059] To provide preload for the limiting post 601, the locking element 602 is a turnbuckle, with both ends of the turnbuckle connected to the limiting post 601, which also facilitates adjustment by employees.

[0060] Among them, such as Figure 3 As shown, the locking component 602 is a wire winding component. The locking component 602 has a simple structure, low cost, and its position can be adjusted according to the user's selection.

[0061] To further ensure the stability of the entire device, the side pull assembly 6 in this application is at least two sets, and the two sets of side pull assemblies 6 are arranged along the length direction of the limiting plate 1. The stability is further improved by the multiple side pull assemblies 6 arranged at intervals.

[0062] To better achieve the stability and position adjustability of jack 3, such as Figure 2 As shown, the adjustable support plate 5 includes:

[0063] Base plate 501, preferably a flat plate;

[0064] Four support screws 502 are respectively installed at the four corners of the base plate 501;

[0065] Four screw cylinders 503 are rotatably and one-to-one installed on the support screw 502. By cooperating with the screw cylinders 503 and the support screw 502, the support plate can be adjusted up and down, thereby achieving the support and stable adjustment of the position of the jack 3.

[0066] The support plate 504 is disposed on the screw cylinder 503, and the stability of the support plate 504 can be ensured by the support of multiple screw cylinders 503.

[0067] In one embodiment, it further includes a measuring component 7 mounted on the adjustable support plate 5, the measuring component 7 being used to measure the corresponding displacement.

[0068] The measuring component 7 further includes:

[0069] The measuring bracket 701 is installed on the adjustable support plate 5. The measuring bracket 701 is designed to facilitate the subsequent installation of the dial indicator. Its height is higher than that of the jack so as not to affect the operation of the jack.

[0070] A dial indicator 702 is mounted on the measuring bracket 701, and the measuring end of the dial indicator 702 is engaged with the force plate 2.

[0071] In this application, the height of the load-bearing plate 2 is lower than the height of the limiting plate 1, which ensures that the test soil is inside the cavity during the test and guarantees the test results.

[0072] Further explanation is provided regarding this application:

[0073] First, the soil layers are separated using a limiting plate, and then the adjustable support plate described in this application is installed. A load-bearing plate is placed on the load-bearing surface of the test soil, and then a jack is installed. The output end of the jack is connected to the load-bearing plate, and the adjustable support plate is adjusted so that the jack is in the corresponding position. Then the locking parts are tightened, and a measuring bracket is installed. The displacement of the load-bearing plate is measured using the measuring end of a dial indicator.
