Description

Technical Field

[0001] This utility model relates to the field of grouting technology in geotechnical engineering, and specifically to a grouting device for geotechnical engineering. Background Technology

[0002] With the acceleration of urbanization and industrialization in my country, and the increasing density of infrastructure construction such as transportation networks, the available land resources are decreasing. Many coal mine subsidence areas are gradually being designated as industrial and civil construction sites, resulting in some areas having to build highways, railways, bridges, tunnels, commercial buildings and other structures on or through the subsidence areas.

[0003] Existing geotechnical grouting equipment uses a mixing drum to mix the grouting material evenly, then connects the mixing drum to the grouting pipe, and then personnel place the grouting pipe into the ground grouting buried pipe. During the process of placing the grouting pipe into the grouting buried pipe, the grouting pipe may deflect or tilt, resulting in low grouting efficiency. Utility Model Content

[0004] In view of this, the present invention provides a grouting device for geotechnical engineering. The present invention can improve the stability of the grouting head installed on the grouting pipe, thereby improving the grouting efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a grouting device for geotechnical engineering, including a movable base plate, a mixing drum on the upper surface of the movable base plate, a discharge hose on the side end of the mixing drum, and a fixed installation assembly on the end of the discharge hose. The fixed installation assembly includes a grouting head on the end of the discharge hose, a support plate on the grouting head, and two grooves on the bottom of the support plate. A circular pipe clamping block is slidably disposed within the two grooves. Because the grouting head and the discharge hose have internal and external threads, and the grouting head can be rotated, the grouting head is mounted on the discharge hose. Then, by inserting the grouting head into the grouting pipe, the circular pipe clamping block slides on the grooves of the support plate, thereby clamping the grouting pipe. Finally, by stirring the mixture in the mixing drum through the discharge hose, the shaking of the grouting pipe is prevented, thus improving grouting efficiency.

[0006] The fixed installation assembly also includes threaded rods on both sides of the support plate. One end of the threaded rod is fixedly installed on the side of the round pipe clamping block by a bearing. That is, the threaded rod rotates on the support plate, thereby pushing the round pipe clamping block and clamping the grouting buried pipe.

[0007] The fixed mounting assembly also includes drive buttons located on both sides of the support plate, which are connected to the ends of the threaded rod; that is, the drive buttons provide torque to the threaded rod, thereby facilitating the rotation of the threaded rod.

[0008] The upper surface of the movable base plate is provided with a support strip, and the top of the support strip is provided with a support block; that is, the support block is used to provide support for the discharge hose.

[0009] The mixing drum is equipped with a mud pump, one end of which is connected to the end of the discharge hose; that is, the mud pump can guide the grouting material inside the mixing drum into the discharge hose.

[0010] The mixing drum is equipped with a mixing assembly, which includes a mixing rod inside the mixing drum and multiple mixing blades at the end of the mixing rod; that is, multiple mixing blades are installed on the mixing rod to mix the grouting material in the mixing drum and prevent the grouting material in the mixing drum from solidifying.

[0011] A motor is installed at the top of the mixing drum, and the output shaft of the motor is connected to the mixing rod; that is, the output shaft of the motor can drive the mixing rod to rotate.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. The grouting head enters the grouting pipe, and then the drive knob is rotated to drive the threaded rod to rotate. This indirectly causes the threaded rod to move the round pipe clamping block close to the outer arc surface of the grouting pipe, thereby clamping the grouting pipe. This improves the stability of the grouting head on the grouting pipe and thus improves the grouting efficiency.

[0014] 2. The grouting material is added into the mixing drum, and then the output shaft of the motor drives the mixing rod, which in turn drives multiple mixing blades to mix the grouting material evenly. Then, by operating the mud pump, the grouting material in the mixing drum is extracted and transported onto the discharge hose, which facilitates the guiding and conveying of the grouting material.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] like Figure 1-3 As shown: This embodiment provides a grouting device for geotechnical engineering, including a movable base plate 100. The movable base plate 100 has multiple casters at its bottom. A mixing drum 101 is respectively mounted on the upper surface of the movable base plate 100. The mixing drums 101 are placed and installed on the movable base plate 100. A feed inlet 105 is provided at the top of the mixing drum 101 and is fixedly installed on the mixing drum 101 by welding, thereby adding grouting materials. A discharge hose 102 is provided at the side end of the mixing drum 101. A fixing assembly 200 is provided at the end of the discharge hose 102. The fixing assembly 200 includes components located at the end of the discharge hose 102. The device is equipped with a grouting head 201, which has an external thread that rotates to connect with the internal thread on the discharge hose 102, allowing the grouting head 201 to enter the grouting pipe. A support plate 202 is mounted on the grouting head 201 by welding. Two sliding grooves 204 are provided on the bottom of the support plate 202, and round pipe clamping blocks 203 are slidably disposed in the two sliding grooves 204. The round pipe clamping blocks 203 can move within the two sliding grooves 204, thereby clamping and fixing both ends of the grouting pipe, improving the stability of the grouting head 201 on the grouting pipe, and thus improving the grouting efficiency.

[0024] Fixed installation components 200 such Figure 3 As shown,

[0025] The fixed installation assembly 200 also includes threaded rods 205 disposed on both sides of the support plate 202. The threaded rods 205 can rotate on the support plate 202. One end of the threaded rods 205 is fixedly mounted on the side end of the round tube clamping block 203 by bearings.

[0026] The fixed mounting assembly 200 also includes drive buttons 206 disposed on both sides of the support plate 202. The drive buttons 206 are connected to the ends of the threaded rod 205, so that it is convenient for personnel to provide torque to the drive buttons 206, thereby facilitating the rotation of the threaded rod 205.

[0027] Rotating the drive button 206 drives the threaded rod 205, causing it to rotate and move within the internal threaded hole on the support plate 202. This causes the threaded rod 205 to contact the round pipe clamping block 203, which then clamps and fixes one end of the grouting pipe, thus preventing the grouting pipe from shaking during grouting.

[0028] Support bar 104 Figure 1 As shown,

[0029] A support bar 104 is provided on the upper surface of the upper surface of the movable base plate 100. The support bar 104 is fixedly installed on the movable base plate 100 by welding. A support block 103 is provided at the top of the support bar 104. The support block 103 is arc-shaped, which is used to support the discharge hose 102, so that the discharge hose 102 can discharge vertically.

[0030] 106 mud pump Figure 2 As shown,

[0031] A mud pump 106 is installed inside the mixing drum 101. The mud pump 106 can extract viscous grouting material. One end of the mud pump 106 is connected to the end of the discharge hose 102. The mud pump 106 is placed inside the mixing drum 101 to extract the grouting material inside the mixing drum 101 and transport it to the discharge hose 102.

[0032] A stirring assembly 300 is provided inside the stirring drum 101. The stirring assembly 300 includes a stirring rod 302 disposed inside the stirring drum 101, and a plurality of stirring blades 303 are provided at the end of the stirring rod 302.

[0033] A motor 301 is installed at the top of the mixing drum 101, and the output shaft of the motor 301 is connected to the stirring rod 302;

[0034] When the motor 301 is started, it causes the stirring rod 302 to rotate, which in turn causes the stirring blade 303 to rotate. This allows the grouting material inside the mixing drum 101 to be stirred evenly, effectively preventing the grouting material from solidifying inside the mixing drum 101.

[0035] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
