Abstract

A replaceable external anchor cable includes an anchor for anchoring a cable body, a separation device, the cable body and grouting materials, wherein a conical hole is formed in the larger end of an internal hole of an anchor bearing plate of the anchor, and a straight hole is formed in the smaller end of the internal hole; a sealing groove is formed in the conical hole of the anchor bearing plate and filled with seal pieces; the separation device is a conical separation pipe with a larger conical end and a smaller straight cylindrical end; the conical separation pipe is inserted into and bonded with the internal hole of the anchor bearing plate, and is integrated with a cable body external sleeve at the outlet of the anchor bearing plate; when pressed, the conical separation pipe clings to the internal wall of the conical hole of the anchor bearing plate and compresses the seal pieces; the conical separation pipe and the cable body external sleeve are both made of weldable plastics, and are integrated through welding at the outlet of the anchor bearing plate; the seal piece materials in the sealing groove are rubber, sealant or sealing gum. The replaceable external anchor cable has the advantages of simple and compact structure, low cost and convenience for construction.

Description

A kind of interchangeable external anchor cable

Technical field

The utility model relates to a kind of external prestressing structure---a kind of interchangeable anchor cable, particularly a kind of interchangeable external anchor cable that is applicable to bridge and building etc.

Background technology

As shown in Figure 2, domestic a kind of interchangeable external anchor cable is comprised of anchor plate 21, spacer assembly 22, cable body 23 and grouting material 25, spacer assembly 22 comprises several parts such as inner sleeve 221, constraint grip assembly 222 and extension spray lance 223, there is following weak point in this structure: 1. complex structure, cost is higher: spacer assembly 22 is comprised of inner sleeve 221, constraint grip assembly 222 and extension spray lance 223 etc. several parts, each parts is comprised of 2～3 parts again, the material of each part is also different, has steel sheet, steel plate, steel pipe, rubber and nylon etc.; Various materials will be pressed respectively different process processing, and last assembling match, causes whole anchor head complex structure, and cost is higher.

2. sealing effectiveness is bad, easily spillage: whole isolation structure is comprised of the part of multiple material and different processing technologys, and mismachining tolerance causes spacer assembly and cable body junction to have gap, and sealing effectiveness is bad, particularly easy spillage during enhancing perfusion.

Summary of the invention

The purpose of this utility model is to provide a kind of interchangeable external anchor cable, and this anchor cable has compact conformation, good seal performance, cost is low and the advantage such as easy construction; The technical problems such as existing interchangeable external Anchor Cable Technique complex structure, cost are high to solve, spacer assembly and the bad easy spillage of cable body junction sealing effectiveness.

The technical scheme addressing the above problem is: a kind of interchangeable external anchor cable, comprises and it is characterized in that ground tackle, spacer assembly, cable body and the grouting material of anchoring cable body:

The large end of anchor plate endoporus of the anchor plate of this interchangeable external Anchor Cable Anchorage is round taper hole, and small end is straight hole, in the round taper hole of anchor plate, has sealed groove, is filled with seal in sealed groove;

Described spacer assembly is taper isolated tube, and the large end of this taper isolated tube is conical, and small end is straight cylinder shape;

Taper isolated tube inserts anchor plate endoporus and the laminating of anchor plate endoporus, and its small end stretches out outside anchor plate, and in anchor plate exit, taper isolated tube and cable body outer tube link into an integrated entity; During pressurization, taper isolated tube is close to anchor plate round taper hole inwall, and compressive seal.

Its further technical scheme is: described taper isolated tube, cable body outer tube are all by making by welding plastic, described can comprise HDPE, PE, PVC or PP by welding plastic, at anchor plate exit taper isolated tube and cable body outer tube, by welding manner, links into an integrated entity.

Its further technical scheme be: the cross section of the sealed groove having in the round taper hole of described anchor plate is semicircle, rectangle or ellipse, the seal being filled in sealed groove is O-ring seals or encapsulant, and described encapsulant comprises sealant and silicone sealant.

Owing to adopting technique scheme, the beneficial effect of a kind of interchangeable external anchor cable of the utility model is:

1. owing to having greatly reduced component kind and quantity, thereby a kind of interchangeable external anchor cable of the utility model is compared with existing interchangeable external anchor cable: compact conformation, and volume little (its anchor plate is less by 1/3 than the anchor plate volume of existing structure), cost of manufacture is low.

2. the taper isolated tube arranging stretches out anchor plate mouth and the welding of cable body outer tube, simple in structure, has therefore also simplified installation, can lashing as rope in conventional body.

3. during mud jacking, utilize conical surface wedging principle that taper isolated tube and anchor plate taper hole are close to, compressed gasketing material, thus realize the wiper seal of anchor cable, can effectively prevent slurry seepage.

Below in conjunction with drawings and Examples, the technical characterictic of a kind of interchangeable external anchor cable of the utility model is described further.
