Description
Technical field
It the utility model is related to technical field of building construction, more particularly to anchor cable aperture sealing structure.
Background technology
Anchor cable construction is a kind of supporting means the most frequently used in current Deep Foundation Pit Supporting Project, especially in coastal area,
As foundation depth is more and more deeper, in the high loose Flooding in Borehole construction of level of ground water, it is usually present water burst, gushes the problems such as sand,
Cause pore-forming difficult, or even cause surrounding formations to sink, seriously endangering other facilities (such as road, building etc.) of foundation ditch periphery
Safety.
The engineering roadblock of Sand during for anchor cable construction is general using improving construction technology and plus anti-water burst in engineering
Gush sand device.The improvement of construction technology can typically solve the problems, such as to be difficult to pore-forming in high water head layer of sand, but Sand is also
It is to be difficult to avoid that.The conventional processing mode in scene has processing is anti-to gush sand device in practical operation, adds expansion water-stop tampon to live aperture,
Or use chemical grouting method sealing of hole.Processing prevents that gushing sand device easily implements, and does not influence other constructions, but device design and making essence
Degree requires higher, is also not easy thoroughly to block Sand.Expansion water-stop cotton is simple to operate, easy for construction, to processing one
As Sand phenomenon effect it is more apparent, but the Sand amount to high water head artesian water it is larger situation effect it is limited, it is difficult
Effectively to handle.Chemical grouting method uses the chemical flooding into leak anchor cable hole, will carry out anchorage cable stretching after water seal again,
Occur leak anchor cable hole after drawing again, inject polyurethane solutions using after rat holing beside anchor cable hole, embedment Grouting Pipe, until
By water seal.The processing method complex operation, the situation effect larger to the Sand amount of high water head artesian water are also limited.
Utility model content
Anchor cable aperture provided by the utility model sealing structure, solve one or more in prior art problem.
Anchor cable aperture provided by the utility model sealing structure, including can seal body close-fitting with anchor cable hole, close
The both ends of envelope body are provided with fixed plate, and seal body, which is provided with the first through hole that can hold anchor cable and pass through, injected hole, fixed plate and is provided with, divides
The second not corresponding with first through hole, injected hole through hole.
Anchor cable aperture provided by the utility model sealing structure, can prevent the expansion at seal body both ends so that expansion
Effect concentrate on anchor cable hole wall, sealing effectiveness is fabulous, and cost it is low, it is simple in construction, easy to use, do not need corollary equipment, energy
Effectively prevent Sand.
In some embodiments, in addition to for fixed plate to be fixed on to the screw bolt and nut of seal body, fixed plate
The third through-hole that can hold bolt and pass through is equipped with seal body, bolt sequentially passes through fixed plate, sealing originally by third through-hole
Body, fixed plate, nut coordinates with screw to be fixed.
In this way, the both ends for being fixed on seal body that fixed plate can consolidate, and it is easy for assembly.
In some embodiments, injected hole includes the first injected hole, the second injected hole.
In this way, the first injected hole and the second injected hole can realize slip casting twice, meet that what anchor cable can consolidate is fixed on anchor
Demand in rope hole.
In some embodiments, seal body uses water-swellable plastic material.
In this way, the material of water-swellable enables seal body more closely to be contacted with anchor cable hole wall, good sealing effect.
Brief description of the drawings
Fig. 1 is a kind of side view of the anchor cable hole sealing structure of embodiment provided by the utility model；
Fig. 2 is a kind of front view of the anchor cable hole sealing structure of embodiment provided by the utility model；
Fig. 3 is the side view after a kind of water-swellable of the anchor cable hole sealing structure of embodiment provided by the utility model
Figure.
Embodiment
The utility model is further described with reference to Figure of description.
As Figure 1-3, anchor cable hole sealing structure provided by the utility model, including can be close-fitting close with anchor cable hole
Body 1 is sealed, the both ends of seal body 1 are provided with fixed plate 2, and seal body 1, which is provided with, can hold first through hole 11, the slip casting that anchor cable passes through
Hole 12, fixed plate 2 are provided with the second corresponding with first through hole 11, injected hole 12 respectively through hole.
Anchor cable aperture provided by the utility model sealing structure, can prevent the expansion at the both ends of seal body 1 so that expansion
Effect concentrate on anchor cable hole wall, sealing effectiveness is fabulous, and cost it is low, it is simple in construction, easy to use, do not need corollary equipment, energy
Effectively prevent Sand.
In actual production, the quantity of first through hole 11 does not limit, based on according to demand.Here it is considered that building site is applied
Avoid construction to be every time required for producing different seal bodies 1 in work, make trouble.So as the daily need that can meet
Will, first through hole 11 is traditionally arranged to be 6, and 6 first through hole 11 are distributed in seal body 1, can be used in construction commonly using
Two ropes, three ropes, four ropes, five ropes, six ropes anchor cable access, no first through hole 11 can clog with plug, so can be with
It is adapted to the installation of multiply anchor cable in identical seal body 1.
When needing to seal anchor cable hole, anchor cable is initially passed through into seal body 1, afterwards pushed away seal body 1 along anchor cable
Enter anchor cable hole, cement mortar is injected to anchor cable hole inside by injected hole 12, easy to use, good sealing effect, can be saved
The time much constructed, improve efficiency of construction.
Further, in addition to for fixed plate 2 to be fixed on to the bolt 3 and nut 4 of seal body 1, fixed plate 2 and close
Envelope body 1, which is equipped with, can hold the third through-hole 5 that bolt 3 passes through, and bolt 3 sequentially passes through fixed plate 2, sealing by third through-hole 5
Body 1, fixed plate 2, nut 4 coordinates with bolt 3 to be fixed.So fixed plate 2 can be fixed on seal body 1 at firm, simplicity
Both ends.In this embodiment, bolt 3 can use tommyhead bolt, can so save the quantity of nut 4.
Wherein, injected hole 12 includes the first injected hole 121, the second injected hole 122.So when first time is from injected hole 121
Slip casting enters anchor cable hole, after internal cement slurry sets reduce, can from the second slip casting into anchor cable hole again of injected hole 122,
Cement mortar is supplemented to anchor cable hole inside, improves the intensity that anchor cable is fixed in anchor cable hole.
Further, water-swellable plastic material is used as preferable one embodiment, seal body 1.Due to sealing
The both ends of body 1 are equipped with fixed plate 2, so when seal body 1 meets water, the side wall that past can be only bonded with anchor cable hole expands,
So make it that sealing effectiveness is higher, avoid anchor cable hole leakage sand, leak, influence the fixation of anchor cable.
The above is only some embodiments of the present utility model.For the person of ordinary skill of the art, not
On the premise of departing from the utility model creation design, various modifications and improvements can be made, these belong to the utility model
Protection domain.
