Abstract
A kind of expansion type prestress anchorage cable, comprise anchor head, anchor cable, backing plate and ground tackle, it is characterized in that, one end of anchor head and anchor cable is affixed, and double-end expansion pipe box is on anchor cable, double-end expansion pipe is divided into cylindrical portion, stage casing, oared segrne pii, the side of cylindrical portion and oared segrne pii all has evenly distributed rectangular channel, and the cylindrical portion of double-end expansion pipe is positioned at anchor head end, and hollow location plug is arranged on anchor cable, backing plate, intermediate plate and ground tackle are enclosed within anchor cable, and backing plate has injected hole.Expansion type prestress anchorage cable of the present utility model, not only can accomplish that construction is disposable to complete, easy construction, and stretch-draw can be carried out while anchor cable is installed, shorten the engineering time, increase work efficiency, reduce the unsafe factor that in conventional anchor work progress, stress release produces, utilize deep to stablize rock stratum, as early as possible active prestress is implemented to tunnel surrounding or side slope, accomplish the effect of active prestress supporting country rock, significant to safe and efficient construction.
Description
Technical field
The utility model relates to tunnel surrounding, slope reinforcement treatment facility, especially a kind of expansion type prestress anchorage cable
.
Background technology
In tunnel or slope reinforcement process engineering, must adopt anchor cable, the anchor cable used at present nearly all needs the materials such as Anchor Agent, mortar or resin cementing.Adopt in this way; in construction; because working procedure is more, complex procedures; waste time and energy; and cementitious materials intensity raising required time affects programming; so often there will be anchor cable and ground without cementing or cementing appearance cavity situation in various degree, be difficult to the compound beam and the suspension function that play anchor cable.In addition, anchor cable is in tunnel and slope construction, and people usually can use inferior materials and turn out substandard goods, and cause the principal element of this phenomenon to be the cementing complexity of anchor cable and country rock, difficulty.
Summary of the invention
The purpose of this utility model be just to provide a kind of easy to operate, construct consuming time less, operating efficiency is high, the expansion type prestress anchorage cable that is connected firmly.
Expansion type prestress anchorage cable of the present utility model, comprise anchor head, anchor cable, backing plate and ground tackle, it is characterized in that, one end of anchor head and anchor cable is affixed, and double-end expansion pipe box is on anchor cable, double-end expansion pipe is divided into cylindrical portion, stage casing, oared segrne pii, the side of cylindrical portion and oared segrne pii all has evenly distributed rectangular channel, and the cylindrical portion of double-end expansion pipe is positioned at anchor head end, and hollow location plug is arranged on anchor cable, backing plate, intermediate plate and ground tackle are enclosed within anchor cable, and backing plate has injected hole.
Expansion type prestress anchorage cable of the present utility model, during use, the cylindrical portion of double-end expansion pipe is contacted with anchor head, hollow location plug is installed at double-end expansion pipe oared segrne pii place, locate between plug cementing with Anchor Agent at anchor cable and hollow, by anchor head, anchor cable and double-end expansion pipe are sent in the boring of country rock by conduit, when anchor head arrives at bottom wall rock drill-hole, take out conduit, backing plate covers aperture, stretch-draw is carried out by hollow jack pair anchor cable, double-end expansion pipe oared segrne pii is opened and is produced with country rock inside the bond stress that rubs, reach fixed effect, carry out slip casting by the anchor cable that the injected hole on backing plate is good to stretch-draw again to close, realize anchoring section bidirectional stress, improve the stressed effect of anchor cable.
Expansion type prestress anchorage cable of the present utility model, not only can accomplish that construction is disposable to complete, easy construction, and stretch-draw can be carried out while anchor cable is installed, shorten the engineering time, increase work efficiency, reduce the unsafe factor that in conventional anchor work progress, stress release produces, utilize deep to stablize rock stratum, as early as possible active prestress is implemented to tunnel surrounding or side slope, accomplish the effect of active prestress supporting country rock, significant to safe and efficient construction.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is parts structural representation in Fig. 1;
In accompanying drawing: 1, anchor head, 2, double-end expansion pipe, 3, hollow location plug, 4, backing plate, 5, injected hole, 6, intermediate plate 7, ground tackle, 8, anchor cable, 21, stage casing, 22, cylindrical portion, 23, rectangular channel, 24, oared segrne pii.
Detailed description of the invention
In the drawings, by anchor cable 8 and double-end expansion pipe 2 assembly and connection, from anchor cable 8 tail end, double-end expansion pipe 2 is inserted in, expansion tube cylindrical portion 22 is contacted with anchor head 1, at double-end expansion pipe oared segrne pii 24 place by installation hollow location plug 3, locate between plug 3 cementing with Anchor Agent at anchor cable 8 and hollow, act as fixing double-end expansion pipe 2 and keep stable in a non-operative state, stretch-draw length reserved by anchor cable 8, completes assembling.
During work, utilize instrument to country rock pore-forming, by conduit, anchor head 1, double-end expansion pipe 2 are sent in the hole of shaping, arrive at bottom position, conduit is pulled out, at country rock aperture place, backing plate 5, ground tackle 6 and intermediate plate 10 are installed, completed by hollow jack and stretch-draw is carried out to anchor cable 8, double-end expansion pipe oared segrne pii 24 is moved backward and embeds country rock inside, form a counter-force and fix anchor head.Drawing is carried out when not carrying out slip casting, double-end expansion pipe cylindrical portion 22 is opened and is produced with country rock inside the bond stress that rubs, reach fixed effect, and then carry out slip casting by the anchor cable that injected hole 5 pairs of stretch-draw are good and close, better compound beam and the suspension function playing anchor cable.
