Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a soil layer anchor rod for building engineering. Background Art

[0002] Soil anchor is a commonly used foundation reinforcement and support structure used to enhance the stability and tensile strength of the soil. When installing soil anchor, the installation location is generally pre-drilled and then the soil anchor is driven into the soil. To facilitate pouring, holes are opened on the soil anchor to allow cement to flow out. However, after the soil anchor enters the soil, the holes are easily blocked by soil, making it difficult to discharge the cement during subsequent pouring, affecting the pouring effect.

[0003] Therefore, a soil anchor rod for construction engineering is now developed for the problems mentioned above. Utility Model Content

[0004] In order to overcome the disadvantage that after the existing device enters the soil, the holes are easily blocked by soil, which makes it difficult to discharge the cement during subsequent pouring and affects the pouring effect, the utility model provides a soil anchor rod for construction engineering.

[0005] The technical solution of the utility model is: a soil anchor rod for a construction project, comprising an anchor steel bar, a grouting barrel connected to the lower part of the anchor steel bar, a connecting barrel connected between the anchor steel bar and the grouting barrel, a connecting pipe for injecting cement connected to the right side of the connecting barrel, a one-way mechanism for preventing soil from clogging holes and enhancing insertion firmness is provided on the grouting barrel, the one-way mechanism comprises a guide barrel, the grouting barrel is connected to nine guide barrels, connecting rods are slidably connected in the guide barrels, and conical blocks are connected to the outer ends of the connecting rods.

[0006] In addition, it is particularly preferred that an auxiliary anchoring mechanism is further included, and the auxiliary anchoring mechanism includes a welding plate, and a plurality of welding plates are welded to the outer side of the lower part of the grouting cylinder, and a plurality of protruding blocks are connected to the welding plates.

[0007] In addition, it is particularly preferred that a connecting sleeve for connecting to power equipment is provided on the top of the anchor steel bar.

[0008] In addition, it is particularly preferred that a conical portion is connected to the bottom of the grouting tube, an embedding groove is opened on the grouting tube, and a connecting block is connected to the top of the grouting tube, and the connecting block is connected to the anchor steel bar.

[0009] Furthermore, it is particularly preferred that every three guide cylinders form a group and are distributed on a uniform horizontal plane.

[0010] In addition, it is particularly preferred that the protruding blocks are all inclined structures.

[0011] By adopting the above technical solution, the advantages of the utility model are:

[0012] 1. During the installation process, the utility model relies on the conical block and the connecting rod to seal the guide tube, so as to prevent the soil from entering the grouting tube through the guide tube during the installation process, affecting the normal pouring and discharge of cement. After the installation is completed, the connecting rod and the conical block are pushed outward by the driving force of the cement, so that the conical block is inserted into the soil to achieve the reinforcement effect.

[0013] 2. When the grouting tube of the utility model is driven into the soil, the welding plate and the raised block will be driven to move together synchronously, thereby relying on the inclined guidance of the raised block to make it difficult to pull out the grouting tube after installation, further assisting the device in anchoring installation and improving the installation firmness of the device.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] A soil anchor for construction engineering, such as Figure 1-Figure 3 As shown, it includes an anchoring steel bar 1, a connecting sleeve 2 for connecting to a power device is arranged on the top of the anchoring steel bar 1, a grouting tube 3 is connected to the lower part of the anchoring steel bar 1, a conical part 301 is connected to the bottom of the grouting tube 3, an embedding groove 302 is opened on the grouting tube 3, a connecting block 303 is connected to the top of the grouting tube 3, the connecting block 303 is connected to the anchoring steel bar 1, a connecting tube 4 is connected between the anchoring steel bar 1 and the grouting tube 3, a connecting pipe 401 for injecting cement is connected to the right side of the connecting tube 4, and a one-way mechanism 5 is provided on the grouting tube 3 for preventing soil from clogging the hole and enhancing the insertion firmness.

[0023] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the one-way mechanism 5 includes a guide cylinder 51, and the grouting cylinder 3 is connected to nine guide cylinders 51, each three guide cylinders 51 form a group and are distributed on the same horizontal plane. Connecting rods 52 are slidably connected inside the guide cylinders 51, and the outer ends of the connecting rods 52 are connected to conical blocks 503.

[0024] It should be noted that the soil anchor is a commonly used foundation reinforcement and support structure used to enhance the stability and tensile strength of the soil. When installing the soil anchor, the installation position is generally pre-drilled first, and then the soil anchor is driven into the soil. First, the connecting sleeve 2 is connected to the power equipment, and then the conical part 301 is aligned with the already drilled hole. Then the power equipment is controlled to send the device into the soil, and it rotates at high speed during the sending process to achieve the effect of rapid installation and fixation. In this process, the conical block 503 and the connecting rod 52 cooperate to block the guide cylinder 51 to prevent soil from entering the guide cylinder 51 during the installation process. 1, resulting in the grouting tube 3 being blocked. When the device is sent to the specified position, the power equipment is disconnected from the connecting sleeve 2, and then cement is introduced into the grouting tube 3 through the connecting pipe 401. The cement is continuously filled in the grouting tube 3, and then moves into the guide tube 51, and squeezes and pushes the connecting rod 52, so that the connecting rod 52 drives the corresponding conical block 503 to slide outward, and then the conical block 503 is inserted into the soil to fix the device as a whole. At the same time, as the connecting rod 52 and the conical block 503 slide outward, the guide tube 51 is no longer blocked, and the cement can flow out through the guide tube 51 to achieve the effect of pouring and fixing.

[0025] Example 2

[0026] On the basis of Example 1, Figure 1 and Figure 3As shown, an auxiliary anchoring mechanism 6 is also included, which includes a welding plate 61. A plurality of welding plates 61 are welded on the outer side of the lower part of the grouting tube 3. A plurality of protruding blocks 62 are connected to the welding plates 61, and the protruding blocks 62 are all inclined structures.

[0027] It should be noted that when the grouting tube 3 is driven into the soil, it will simultaneously drive the welding plate 61 and the protruding block 62 to move together, thereby relying on the inclined guidance of the protruding block 62, making it difficult to pull out the grouting tube 3 after the installation is completed, further assisting the device to perform anchoring installation and improving the installation firmness of the device.
