Description

A kind of new side slope protection grouted anchor bar

Technical field

A kind of new side slope protection grouted anchor bar of the utility model, when being related to a kind of civil construction, side slope is protected Grouted anchor bar device, belong to field of civil engineering.More particularly to a kind of device that root fixation can be carried out to anchor pole.

Background technology

At present, it is necessary to which it is the laying anchor net in side slope that side slope, which carries out traditional means of defence, during civil engineering Then whitewashed, form side slope protection layer, but this method is not appointed to simply protecting soil body surface in inside soil body What guard method, it is existing Anchor Care to be carried out by anchor pole, anchor cable is coordinated by anchor pole, but existing anchor pole is squeezing into the soil body When, root is not fixed, although grouted anchor bar be present, existing grouted anchor bar, also will not be right when anchor pole is squeezed into Root is fixed, and pure being solidified by the slurries injected in the soil body forms foundation and fixed, but during anchor pole is squeezed into, Due to the difference of soil body soil property, it may appear that the situation of slip casting channel jam, especially in some the soil layers that the soil is porous so that Slurries are difficult to discharge, and cause anchor pole to be fixed unstable, further to influence Anchor Care effect.

The content of the invention

In order to improve the above situation, a kind of new side slope protection grouted anchor bar of the utility model provides one kind can be to anchor Bar carries out the device of root fixation.It is simple in construction, it is convenient and practical.

A kind of new side slope protection grouted anchor bar of the utility model is realized in：A kind of new side slope of the utility model Protection grouted anchor bar is made up of agent set and root fixing device, agent set by earth's surface pressure ring, big envelope, clamp nut, hold Gland cylinder, circular passage, outer tube, slip casting passage, spacing ring, limiting stand, hollow drill pipe and through hole composition, big envelope is placed in hollow On drilling rod one end, screw thread is equipped with the hollow drill pipe outer surface, the hollow drill pipe is built-in with slip casting passage, the hollow brill Two through holes are symmetrically provided with bar, and are connected respectively with slip casting passage, outer tube is placed on hollow drill pipe, the outer tube Circular passage is equipped with inwall, and is connected by two through holes with slip casting passage, earth's surface pressure ring is placed on outer tube one end, limit Position ring is placed on outer tube other end inwall, and gap is equipped between hollow drill pipe, and clamp nut is placed on hollow drill pipe, and It is meshed with the screw thread on hollow drill pipe outer surface, pressure-bearing sleeve is placed on hollow drill pipe, and is located at clamp nut and earth's surface Between pressure ring, limiting stand is placed on the hollow drill pipe other end, and root fixing device is by anchor pole head, installation groove, point slurry passage, bowl Type lid, elastic shrouding and extension pawl composition, anchor pole head are placed on the hollow drill pipe other end, and it is recessed that installation is provided with the anchor pole head Groove, multiple extension dog collar shapes are distributed on the outside of hollow drill pipe, and one end is hinged with anchor pole head respectively, and the multiple extension pawl is located at Between outer tube and anchor pole head, bowl-type lid is placed on the hollow drill pipe other end, and the bowl-type lid is built-in with a point slurry passage, and and note Slurry passage is connected, and multiple elastic shroudings, which correspond, to be placed on multiple extension pawls, and is fitted respectively with bowl-type interior surface, The multiple elastic shrouding and installation groove are corresponding.

In use, needing the place punching of supporting first, then hollow drill pipe is put into hole, until earth's surface pressure ring pressure On the ground, clamp nut then can be screwed, pressure-bearing sleeve is compacted during precession, and hollow drill pipe stress is pulled outward, Hollow drill pipe drives limiting stand and anchor pole head to move, and anchor pole head drives multiple extension pawls movements, outside multiple extension pawls touch During sleeve pipe, with movement, outer tube struts multiple extension pawls, so as to which multiple extension pawls are deeply pricked into drill hole inner wall, centering Empty drilling rod root position is fixed, and improves its supporting effect, meanwhile, multiple extension pawls drive connected elastic shrouding to move respectively It is dynamic, separate elastic shrouding and bowl-type interior surface, so that a point slurry passage is opened, when limiting stand is moved to spacing ring position When, it is spacing to hollow drill pipe progress, prevent hollow drill pipe from continuing to move to, the hinged place of hollow drill pipe and clamp nut is caused brokenly It is bad, capping, the slip casting into hollow drill pipe are then opened, slurries enter in slip casting passage, flowed downward in slip casting passage, part Slurries are flowed into circular passage by through hole, and then are flowed into the gap between spacing ring and hollow drill pipe, grout cures, are made outer Sleeve pipe and hollow drill pipe are integrally formed, and fraction slurries are flowed into point slurry passage, are then penetrated into the gap between hole wall, to root Soil matrix consolidated, the design of the elastic shrouding, can in not slip casting, to point slurry a passage block, reach building In construction, purpose that side slope is protected.

Beneficial effect.

First, it is simple in construction, it is convenient and practical.

2nd, cost is cheap, easy to spread.

Brief description of the drawings
