Description

Technical Field

[0001] This utility model relates to the technical field of anchor cable grouting, and in particular to an auxiliary device for prestressed anchor cable grouting. Background Technology

[0002] In civil engineering construction, such as slope reinforcement and deep foundation pit support, prestressed anchor cables are widely used to enhance the stability of soil and rock masses. During the construction of prestressed anchor cables, the grouting process is crucial, as its quality directly affects the anchoring effect of the anchor cables and the overall safety of the project.

[0003] During grouting, the grouting pipe is inserted into the anchor cable hole. In irregular terrain such as slopes, the grouting pipe and the external supply pipe have a large bending angle, which makes the grouting pipe prone to positional changes in the anchor cable hole during the grouting process, and may even cause the anchor cable to be misaligned, affecting the grouting effect. In order to address the above defects, this application is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a prestressed anchor cable grouting auxiliary device that can solve the problem of large angular deviation between the grouting pipe and the material supply pipe affecting the grouting effect by quickly connecting an external pipe that is adapted to the angle of the grouting pipe.

[0005] To address the aforementioned problems, this utility model provides a prestressed anchor cable grouting auxiliary device, comprising an auxiliary frame, a pump body, a pipe assembly, a connecting component, and a support leg assembly. The pump body is mounted on the auxiliary frame, and a pipe assembly is installed at the pump body's inlet pipe and / or outlet pipe. The pipe assembly includes a fixed pipe and a connecting pipe, which are respectively used to connect to the pump body and the grouting pipe. Both the fixed pipe and the connecting pipe have stepped surfaces, and the connecting pipe includes pipe bodies with several different angles. The connecting component includes two sets of connecting plates and a bolt assembly. The connecting plates are installed at the stepped surfaces, and the bolt assembly is used to tighten the two sets of connecting plates.

[0006] According to one embodiment of the present invention, a sealing ring is provided at the contact end face of the fixed tube and the connecting tube.

[0007] According to one embodiment of the present invention, the outrigger assembly includes a plurality of outriggers with adjustable length.

[0008] According to one embodiment of the present invention, the support leg includes an adjusting screw and a support leg body. The support leg body is installed in an auxiliary frame, and the adjusting screw is connected to the support leg body for adjusting the extension length of the support leg body.

[0009] According to one embodiment of the present invention, an adjusting handwheel is installed on the adjusting screw.

[0010] According to one embodiment of the present invention, a support plate is installed at the bottom of the support leg body.

[0011] According to one embodiment of the present invention, the support plate and the leg body are connected by a ball seat structure.

[0012] According to one embodiment of the present invention, the connecting pipe includes a straight pipe, a right-angle elbow pipe, and several pipe bodies with angles between 90° and 180°.

[0013] The beneficial effects of this utility model are that by setting the connecting pipe, the connection between the supply pipe and the grouting pipe can be quickly realized. According to the terrain requirements, the connecting pipe with a suitable angle can be selected and quickly assembled through the connecting components, avoiding large bending angles between the grouting pipe and the external supply pipe, ensuring the grouting effect. Moreover, since the support leg components are adjustable, the cooperation between the connecting pipe and the support leg components can achieve rapid adjustment and improve efficiency.

[0020] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0021] Example 1:

[0022] A prestressed anchor cable grouting auxiliary device, such as Figure 1 It includes an auxiliary frame 1, a pump body 2, a pipe assembly 3, a connecting assembly 4, and a support leg assembly 6.

[0023] Pump body 2 is installed on auxiliary frame 1. Pump body 2 is used to provide pressure to the grout. It is generally a grouting pump. Here, pump body 2 is generally used to provide secondary auxiliary pressure. The grouting machine pumps the grout into the supply pipe. This auxiliary device is generally used when the anchor cable is in a non-flat terrain such as a slope. The supply pipe needs to be extended to the grouting position.

[0024] Depending on the terrain requirements, a pipe assembly 3 may be installed at the inlet pipe or outlet pipe 21 of the pump body 2.

[0025] like Figure 3 , Figure 4 The pipe assembly 3 includes a fixed pipe 32 and a connecting pipe 31. The fixed pipe 32 and the connecting pipe 31 are respectively used to connect to the feed pipe or discharge pipe 21 of the pump body 2 and the grouting pipe 5. The surfaces of both the fixed pipe 32 and the connecting pipe 31 are provided with stepped surfaces 33. The connecting pipe 31 includes pipe bodies with several different angles; for example... Figure 5 The connecting pipe 31 includes a straight pipe 311, a right-angle elbow pipe 313, and several pipe bodies with angles between 90° and 180°, such as a 120° elbow pipe 312. When using it, select the appropriate pipe body for quick installation according to the angle requirements.

[0026] The feed pipe and discharge pipe of the pump body 2 are connected to the feed port and discharge port of the pump body, respectively. The fixed pipe 32 can be fixed to the pipeline of the pump body by means of pipe clamps or the like.

[0027] The connecting assembly 4 includes two sets of connecting plates 41 and a bolt assembly 42. The connecting plates 41 are installed at the stepped surface 33, and the bolt assembly 42 is used to tighten the two sets of connecting plates 41, enabling quick connection between the fixed pipe 32 and the connecting pipe 31. Figure 4 A sealing ring 35 is provided at the contact end face of the fixed pipe 32 and the connecting pipe 31 to ensure the sealing effect of the connection between the two.

[0028] The outrigger assembly 6 includes four sets of adjustable-length outriggers, such as... Figure 2 The outrigger includes an adjusting screw 62 and an outrigger body 63. The outrigger body 63 is installed in a groove in the auxiliary frame 1 and can move up and down. The adjusting screw 62 is connected to the threaded hole of the outrigger body 63. Rotating the adjusting screw 62 adjusts the extension length of the outrigger body 63. An adjusting handwheel 61 is installed on the adjusting screw 62 for easy manual adjustment. A support plate 64 is fixedly installed at the bottom of the outrigger body 63 to increase the contact area with the ground.

[0029] In use, place the auxiliary frame 1 near the anchor cable hole and adjust the support leg assembly 6 to ensure stable placement of the auxiliary frame 1. The pump body 2 is used to connect the feed pipe and the grouting pipe. Depending on the angle between the feed pipe and the feed pipe of the pump body 2, choose whether to connect them through the pipe assembly 3. When the angle deviation between the two is large, select a suitable connecting pipe 31 for conversion to avoid the deflection force of the feed pipe causing the auxiliary device to tip over. If the feed pipe and the feed pipe of the pump body 2 are in a straight line or can be connected stably, they can be connected directly without the need to install the pipe assembly 3.

[0030] The discharge pipe 21 of the pump body 2 is connected to the grouting pipe 5 through the pipe assembly 3. According to the angle of the grouting pipe 5, a suitable angle connecting pipe 31 is selected. The connecting pipe 31 and the grouting pipe 5 can be fixed with pipe clamps, thus solving the problem that when the traditional grouting pipe and the supply pipe are directly connected, the grouting pipe will be offset and pulled due to the large angle deviation, which will affect the grouting effect.

[0031] Example 2:

[0032] Unlike in Example 1, as Figure 2 The support plate 64 is connected to the leg body 63 by a ball seat structure 65. The support plate 64 can adjust its angle according to the terrain to achieve a better support effect.

[0033] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
