Description

Technical Field

[0001] The utility model relates to the technical field of anchor cable accessories, in particular to a reinforcement pipe structure for an anchor cable end. Background Art

[0002] In the existing technology, with the rapid development of urban construction, the number of multi-story basements and other structures of high-rise buildings is increasing, and there are more and more deep foundation pit projects. Various methods of foundation pit support are constantly emerging. At present, the methods of foundation pit support include SMW method, biaxial cement mixing piles, soil nail wall support, etc. Different foundation pit support methods are often required according to different factors such as foundation pit depth, size, and surrounding environment. Anchor support plays an important role in the slope support process of foundation pit excavation projects with its large anchoring radius, strong anchoring force, and wide reinforcement range. Anchor support is to install anchor cables in the surrounding rock to form anchor bodies to reinforce the surrounding rock and improve the bearing capacity of the surrounding rock. When constructing anchor cables, anchor holes are usually constructed inside the soil layer where the anchor cables need to be installed, and then the anchor cables are inserted into the anchor holes. The anchor cable end structure commonly used in construction at present has a closed pointed cone shape at the front end, and the rear end of the end structure is connected to the steel strand. When the anchor cable end structure enters the deep hole and is grouted, the slurry cannot flow smoothly into the guide cap, and the sediment at the bottom of the hole cannot be discharged with the grouting, resulting in the grouting at the front end of the anchor cable being not dense, which often causes the problem of anchor cable reinforcement failure.

[0003] The Chinese utility model patent with application number: 202020058524.7 discloses an enlarged head anchor drill bit, including: a slurry outlet, a drill bit tip and a drill bit main rod; the drill bit tip is conical and made of tungsten steel alloy; the drill bit main rod is provided with several rows of concave arc surfaces along the axial direction, and each row has three concave arc surfaces evenly distributed, and each concave arc surface is connected to a drill tooth by a hinge, and a drill tooth cutter head is provided on the outside of the drill tooth; there is a drill tooth arc surface on the inside of the drill tooth, the arc angle of the drill tooth arc surface is 60°, and the depth of the drill tooth arc surface is the same as the height of the concave arc surface; the drill tooth height is 3-5 cm greater than the depth of the concave arc surface; the drill tooth is made of tungsten steel alloy. However, the structure of this type of enlarged head anchor drill bit is relatively complex. Its front end is a closed cone shape, and the rear end of the end structure is connected to the steel strand. When the end structure of the anchor enters the deep hole and grouting is performed, the slurry cannot flow smoothly into the guide cap, and the sediment at the bottom of the hole cannot be discharged with the grouting, resulting in the grouting at the front end of the anchor being not dense, which can easily cause the anchor reinforcement to fail.

[0008] The discharge head is configured as a cone-shaped structure, and the interior of the discharge head is configured as a hollow structure, and the interior of the discharge head is communicated with the interior of the reinforcement pipe body.

[0009] The guide port is composed of four groups of adjacently arranged conical cutouts, and the four groups of conical cutouts are connected end to end in sequence to form a symmetrical wedge-shaped opening structure.

[0010] The height of the tapered cutout is half the height of the discharge head.

[0011] The opening angle of the tapered cutout is 64°.

[0012] The distance between the two oppositely arranged groups of tapered cutouts is 18 mm.

[0022] A reinforcing pipe structure for an anchor cable end includes a reinforcing pipe body 1, one end of the reinforcing pipe body 1 is provided with a discharge head 2, the discharge head 2 is integrally formed with the reinforcing pipe body 1, and the end of the discharge head 2 away from the reinforcing pipe body 1 is provided with a guide port 3, the guide port 3 is a symmetrical wedge-shaped opening structure, and the overall structure schematic diagram of the first embodiment of the utility model is as shown in FIG. Figure 1 shown.

[0023] The reinforcement tube body 1 adopts a cylindrical tube body structure and the interior of the reinforcement tube body 1 is set as a hollow structure, the discharge head 2 is set as a conical structure and the interior of the discharge head 2 is set as a hollow structure, the interior of the discharge head 2 is connected with the interior of the reinforcement tube body 1, wherein the reinforcement tube body 1 and the discharge head 2 together constitute a conical reinforcement tube structure, and its interior is hollow to meet the installation requirements of the anchor cable end.

[0024] The guide port 3 is composed of four groups of adjacently arranged conical cuts, which are connected end to end to form a symmetrical wedge-shaped opening structure. The height of the conical cut is half the height of the discharge head 2, the opening angle of the conical cut is 64°, the spacing between the two relatively arranged conical cuts is 18 mm, and the thickness of the reinforcement tube body 1 is 2 mm. The guide port 3 of the symmetrical wedge-shaped opening structure can ensure the stability of the reinforcement tube structure while improving the discharge efficiency of the slurry. The schematic diagram of the cooperation between the guide port 3 and the discharge head 2 in the first embodiment of the utility model is shown in FIG. Figure 2 shown.

[0025] Embodiment 2:

[0026] On the basis of the first embodiment, the rest of the parts remain unchanged, and the structure of the guide port 3 is replaced by a symmetrical wedge-shaped opening structure formed by connecting four groups of arc-shaped cutouts end to end in sequence. The overall structural diagram of the second embodiment of the utility model is shown in FIG. Figure 3 shown.

[0027] Among them, the structure of the guide port 3 can be replaced by a symmetrical wedge-shaped opening structure composed of other similar forms of cuts according to actual use requirements.

[0028] Working principle:

[0029] When in use, the reinforced tube structure is installed at the front end of the anchor cable. When the anchor cable is constructed, the reinforced tube structure can effectively improve the strength of the front end of the anchor cable and guide the anchor cable. When the grouting process is carried out, the slurry flows into the discharge head 2 through the reinforced tube body 1 and flows out of the reinforced tube structure along the guide port 3, which can ensure that the grouting at the front end of the anchor cable is dense, thereby effectively avoiding failure of the anchor cable reinforcement. The guide port 3 with a symmetrical wedge-shaped opening structure can ensure the stability of the reinforced tube structure while improving the discharge efficiency of the slurry.

[0030] The beneficial effect of the utility model is that the structure is simple. The open pointed cone structure at the end of the reinforcement pipe body is formed by the discharge head and the guide port, which can ensure that the slurry flows out of the reinforcement pipe body smoothly, and the sediment at the bottom of the hole can be discharged with the grouting to ensure that the grouting at the front end of the anchor cable is dense, effectively avoiding the failure of the anchor cable reinforcement. Compared with the traditional circular opening or conical incision, the guide port in the present technical solution adopts a symmetrical wedge-shaped opening structure design, which can ensure the stability of the reinforcement pipe structure while improving the discharge efficiency of the slurry. It can easily pierce the anchor agent, reduce the installation resistance of the anchor cable, and can fully stir the anchor agent, break up the anchor agent film, and prevent the anchor agent film from condensing.
