Description

Capsule and anchoring component using the same

technical field

The utility model relates to a pouch and an anchor component using the pouch.

Background technique

There are different amounts of soft soil distributed throughout our country. The silty clay in it has the characteristics of low strength, high compressibility, and long solidification period. If anchor rods are directly used for foundation pit support, the hole wall may easily collapse after the hole is formed. , The controllability of grouting is poor, and the designed uplift bearing capacity is often not reached, and the construction quality is difficult to guarantee. Therefore, it is necessary to use a bladder device to improve the pullout resistance of the anchor. The existing bladder device, such as the "high-pressure pendulum spray follow-up type cloth bag expansion diameter anchor carrier" disclosed in the Chinese patent CN203514329U, includes a bladder and an axial The guide tube extending in the front and rear directions, the front and rear ends of the middle support member are respectively provided with a front end seat and a rear end seat, the front end of the pouch is connected to the front end seat through a holding piece, and the back end of the pouch is connected through a holding piece On the rear end seat, the front end seat is provided with a grouting port, the front and rear end seats and the guide pipe constitute the middle support, and a threading pipe is arranged between the front and rear end seats. When in use, the anchor rod passes through the threading pipe. It is fixed on the rear end seat, and the grout is injected into the bag through the grouting port. The grout expands and deforms the bag, and the expanded bag can improve the pull-out bearing capacity between the bag and the foundation. The problem with the existing connection form of the anchor rod and the capsule bag is that the anchor rod is connected with the capsule bag through the middle support member. The setting of the middle support member increases the production cost of the product on the one hand, and also makes the anchor rod, The connection structure between capsular bags is more complicated.

Contents of the invention

The purpose of this utility model is to improve an anchor assembly to solve the problem in the prior art that the connection structure of the bladder and the anchor rod is complicated due to the need to set a middle support; Pockets connected by anchor rods.

In order to solve the problems referred to above, the technical solution of the pouch in the utility model is:

The pouch includes a pouch body with an inner cavity, the pouch body is provided with anchor rod penetration holes for the corresponding anchor rods to fit through, and the pouch body is provided with a grouting port communicating with the inner cavity.

The pouch body is connected with a first holding member for fixing the pouch body on the anchor rod at the hole where the anchor rod penetrates,

The first clamping member is a hoop.

The pouch body is also provided with an anchor piercing hole corresponding to the anchor piercing hole for the anchor to pass through, and the pouch body is connected to the anchor piercing hole for A second clasping member that fixes the pouch body to the anchor rod.

The technical scheme of the anchor assembly in the utility model is:

The anchoring assembly includes an anchor rod and a pouch, the pouch includes a pouch body with an inner cavity, the pouch body is provided with an anchor penetration hole for the anchor rod to fit through, and the pouch body is provided with a The grouting port communicated with the inner cavity, and the anchoring assembly further includes a first holding member arranged at the penetration hole of the anchor rod to fix the bag body on the anchor rod.

The first clasp is connected to the pouch body.

The first clamping member is a hoop.

A bearing plate is fixed in the inner cavity on the anchor rod.

The bladder body is also provided with an anchor rod penetration hole corresponding to the anchor rod penetration hole for the anchor rod to fit through, and the anchor rod penetration hole is provided with the bladder body The second holding member fixed on the anchor rod.

The second clasp is connected to the pouch body.

The beneficial effect of the utility model is: when in use, the anchor rod directly penetrates into the bag through the anchor rod penetration hole of the pouch body, and the pouch body at the place where the anchor rod penetrates the hole is fixed to the Then, through the grouting hole on the bladder body, grout is injected into the inner cavity of the bladder body to realize expansion and deformation of the bladder. The pouch is directly connected with the anchor rod, eliminating the need for structures such as the corresponding middle support member, simplifying the structure and greatly reducing the production cost and construction cost of the product.

Description of drawings

Fig. 1 is the structural representation of embodiment 1 of anchor assembly in the utility model;

Fig. 2 is a schematic structural view of Embodiment 2 of the anchor assembly in the present invention.

Detailed ways

Embodiment 1 of the anchoring assembly is shown in Figure 1: it includes an anchor rod and a pouch, the pouch includes a pouch body 4 with an inner cavity, the pouch body includes a middle large-diameter section and small-diameter sections arranged at both ends of the middle large-diameter section , the small-diameter section is a tapered structure with a gradually changing diameter, the upper end of the pouch body is provided with an anchor rod penetration hole for the anchor rod 1 to fit through, and the lower end of the pouch body is provided with an anchor for the anchor rod to fit through Rod piercing hole, the bolt piercing hole corresponds to the bolt piercing hole up and down, the pouch body is connected with the first holding member 2 at the anchor piercing hole, and the pouch body is connected to the anchor piercing hole A second holding member 6 is connected, the first and second holding members are hoops, the upper end of the bag body is fixed on the anchor rod by the first holding member, and the lower end of the bag body is fixed by the second holding member. fixed on the anchor rod. A grouting port 3 communicating with the inner cavity of the pouch body is opened on the pouch body. The anchor rod is fixed with a bearing plate 5 in the inner cavity, and the bearing plate is screwed on the anchor rod.

During use, the lower end of the anchor rod penetrates into the inner cavity of the pouch body through the anchor rod penetration hole, and then passes through the anchor rod through hole, and the anchor rod and the folded anchor rod penetrate the hole, and the anchor rod passes out The apertures of the holes are consistent, so the bladder body at the anchor rod penetration hole and the anchor rod penetration hole can be fixed on the anchor rod through the first and second clamping parts, and it can also be fixed between the bladder body and the anchor rod. A sealing ring is set to prevent the grout from leaking out, and then grout is injected into the pouch body through the grouting port to realize expansion and deformation of the pouch. The bearing plate can increase the pulling force between the anchor rod and the cured slurry. The bearing plate is set in the inner cavity of the bag body, so that the bearing plate will not contact the outside, avoiding the problem that the bearing plate is easy to rust, and ensuring The service life of the load plate. In other embodiments of the anchoring assembly: the bearing plate can also be located outside the pouch body, and of course the bearing plate can also be omitted; the hoop can also be replaced by steel wire or other clamping parts; the anchor rod passes through the hole and the second The holding part can also not be provided, and now the lower end of the anchor rod is located in the inner cavity of the bag body; the first and second holding parts can also not be connected to the bag body, such as the first and second holding parts The tight part is separated from the pouch body, and the first and second fastening parts are used to fix the pouch body on the anchor rod only when in use.

Embodiment 2 of the anchoring assembly is shown in FIG. 2 : the difference between Embodiment 2 of the anchoring assembly and Embodiment 1 is that the small-diameter section of the pouch body 4 is a straight cylindrical structure.

The embodiment of the pouch is shown in Figures 1-2: the specific structure of the pouch is the same as that of the pouch described in the embodiments of the above-mentioned anchor rod components, and will not be described in detail here.
