Abstract
The utility model relates to a steel strand group anchor inhaul cable, which is composed of an inhaul cable part and a group anchor device part, wherein, the inhaul cable part comprises a cable body composed of a plurality of steel strands, a pre-buried pipe, a damping device and a transition pipe of a cable hoop; the group anchor device part comprises a clamping sheet, an anchor plate, a screw nut, a supporting cylinder and an extending cylinder 7. The length of the supporting cylinder 6 is two to four times as long as the length of the original supporting cylinder. An inner cavity of the supporting cylinder 6 has definite slope degree and is directly connected with the extending cylinder 7 by a screw thread way. The rear end of the extending cylinder is provided with a sealing device 8, flexible transition is used by the steel strands between the sealing device 8 and the cable hoop 11. The anchor inhaul cable has the advantages of reasonable structure, convenient construction, good anticorrosion performance and durability.
Description
The utility model relates to a kind of steel strand group anchor cable.
With the immediate prior art of the present invention be that number of patent application is 97204767.0 high amplitude steel strand group anchor cable.It mainly partly is made up of drag-line part and group's anchor ground tackle, and drag-line partly comprises the cable body that is made of some steel strand, pre-pipe laying, damping device, parrel, transition conduit; Group's anchor ground tackle partly comprises intermediate plate, anchor slab, nut, carrying cylinder, exntension tubs.Its shortcoming is that the loudspeaker sleeve that is arranged at the anchor slab rear end adopts bolt to be connected with exntension tubs, and loudspeaker sleeve and exntension tubs are installed in the pre-pipe laying, and the operating space is narrow, and difficulty of construction is big; Fill cement mortar in loudspeaker sleeve and the exntension tubs simultaneously, exntension tubs extend to outside the pre-pipe laying, parts in the whole pre-pipe laying are rigidity and connect, when cable body is given a shock, the junction of loudspeaker sleeve and exntension tubs is easy to generate fracture, and therefore the structure of whole steel strand group anchor cable system is reasonable inadequately.
The purpose of this utility model is to provide a kind of can bear fatigue loading amplitude of stress height, simultaneously structure more rationally, easy construction, have under good antiseptic property and durability, the low-stress state the good steel strand group anchor of anchoring property and draw and entangle.
For reaching above-mentioned purpose, solution of the present utility model is: existing steel strand group anchor cable is improved, the carrying cylinder that places the anchor slab rear end is prolonged the back adopt thread connecting mode with exntension tubs, the exntension tubs rear end has one by sealing device, and the steel strand between sealing device and the parrel adopt flexible transition.
Its concrete structure is: a kind of steel strand group anchor cable, partly to form by drag-line part and group's anchor ground tackle, and drag-line partly comprises the cable body that is made of some steel strand, pre-pipe laying, damping device, parrel, transition conduit; Group's anchor ground tackle partly comprises intermediate plate, anchor slab, nut, carrying cylinder, exntension tubs, some taper holes that are circle distribution are arranged on the anchor slab, intermediate plate is housed in the taper hole, the steel strand that pass taper hole are clamped on the anchor slab by intermediate plate tightly, it is characterized in that: these carrying cylinder 6 length are 2～4 times of former carrying cylinder length, its inner chamber has certain gradient, and directly is connected by engage thread with exntension tubs 7, there is a sealing device 8 rear end of exntension tubs 7, and the steel strand between sealing device and the parrel adopt flexible transition (not having fill concrete all around).
Because the loudspeaker sleeve adopts bolt to be connected with exntension tubs in the prior art, and loudspeaker sleeve and exntension tubs are installed in the pre-pipe laying, the operating space is narrow, and difficulty of construction is big.And carrying cylinder of the present utility model and exntension tubs adopt thread connecting mode, directly exntension tubs are screwed in to get final product in the carrying cylinder, and construction is got up efficient and convenient.
A sealing device is arranged behind the exntension tubs of the present utility model, cement mortar is poured between carrying cylinder, exntension tubs inner chamber and anchor slab and the sealing device, screw rod is tightened on the carrying cylinder by locking device and anchor slab, the bond stress that anchoring unit that is made of the intermediate plate anchor slab and the mortar in the carrying cylinder produce clamps steel strand, power is passed on carrying cylinder and the nut then, by nut power is delivered on the member again; Simultaneously the steel strand between sealing device and the parrel adopt flexible transition, have effectively alleviated because cable body vibration and fracture that carrying cylinder and exntension tubs junction are caused; The structure of whole steel strand group anchor cable system is more reasonable, so anchoring property is better and have good antiseptic property and a durability under the low-stress state.
Below, the architectural feature to the steel strand group anchor cable of the utility model is described further in conjunction with the accompanying drawings and embodiments.
Fig. 1: the steel strand group anchor cable structural representation of the utility model.
Embodiment
A kind of steel strand group anchor cable.As shown in the figure, this steel strand group anchor cable partly is made up of drag-line part and group's anchor ground tackle, and drag-line partly comprises the cable body 14 that is made of some steel strand, pre-pipe laying 9, damping device 10, parrel 11, transition conduit 12; Group's anchor ground tackle partly comprises intermediate plate 3, anchor slab 4, nut 5, carrying cylinder 6, exntension tubs 7, some taper holes that are circle distribution are arranged on the anchor slab 4, intermediate plate 3 is housed in the taper hole, the steel strand that pass taper hole are clamped on the anchor slab 4 tightly by intermediate plate 3, these carrying cylinder 6 length are 2～4 times of former carrying cylinder length, its inner chamber has certain gradient, and directly is connected by engage thread with exntension tubs 7, there is a sealing device 8 rear end of exntension tubs 7, and irritating between carrying cylinder 6, exntension tubs 7 inner chambers and anchor slab 4 and sealing device 8 has mortar 15; Steel strand between sealing device 8 and the parrel 11 adopt flexible transition (not having fill concrete all around).
As a kind of conversion of the present utility model, the rear end inner chamber of carrying cylinder 6 has a step, and screw thread is arranged in the step, also is furnished with screw thread on the front end outer wall of exntension tubs 7, and exntension tubs 7 screw in the internal thread of carrying cylinder 6.
