Abstract
The invention discloses a kind of earth anchor, the tension assembly comprising tieback connection I and be connected with tieback connection I, described tension assembly comprises several tension unit and by the connector II of detachable for tension unit connection; Detachable transport, assembling uses, and malformation is flexible, is suitable for using as temporary guy dish; Each several part adopts steel frame construction, and supporting capacity is strong, is convenient to recycling, reduces cost, good in economic efficiency.
Description
Technical field
The invention belongs to earth anchor field, relate to a kind of combined type earth anchor can reused, detachably transport.
Background technology
Anchor instrument to be used during the construction of power circuit tower bar, but the earth anchor used at present mostly is the cement cable quadrant of concreting, this cement cable quadrant weight is larger, be suitable for using as permanent cable quadrant, if use as temporary guy dish, then carry transport inconvenience, be unfavorable for that the problems such as recycling exist, although the temporary guy dish also having other forms of earth anchor (as ship sections earth anchor) to can be used as when tower bar is constructed at present uses, but these earth anchors have again a common problem: be only applicable in the less power circuit tower bar of trnamission capacity, the tower bar larger for those trnamission capacities then can not be suitable for because its load that can bear is less, construction requirement cannot be met.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of alternative cement cable quadrant, be convenient to transport, can recycling, be suitable for as temporary guy dish combined type earth anchor.
For achieving the above object, the invention provides following technical scheme: a kind of earth anchor, the tension assembly comprising tieback connection I and be connected with tieback connection I, described tension assembly comprises several tension unit and by the connector II of detachable for tension unit connection; Described tension unit is steel pipe or steel bar, and described connector II comprises the junction plate be arranged in the middle part of tension unit and the bolt be arranged on junction plate, and described tension unit connects into bamboo raft type structure by junction plate and bolt.
Further, described tieback connection I is the boatswain chair be connected with tension unit, described boatswain chair is provided with drag-line connecting hole.
Further, also comprise the covering covered on tension unit, described covering is provided with the covering frame for being fixed on by covering on tension unit.
Beneficial effect of the present invention is:
(1) be assembled by multiple part, when travelling bogie cannot transport, a few part can be disassembled into carried respectively by several workman, be convenient to transport, be particularly suitable for the ungetable areas such as mountain area, during use, be assembled into one, convenient, flexible, dig out after finishing using and take away, be suitable for using as temporary guy dish;
(2) several tension unit is connected to form bamboo raft type structure by connector II, and its overall structure specification, supporting capacity are equivalent to cement cable quadrant, can substitute cement cable quadrant completely, each several part adopts steel frame construction, can recycling completely, reduce cost, good in economic efficiency.
Accompanying drawing explanation
In order to make object of the present invention, technical scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the explosive view of Fig. 1;
Fig. 3 is the positive direction view of the present invention after removal covering;
Figure 4 Wei 〦 type structural representation;
Fig. 5 is+type structural representation;
Fig. 6 is for connecting block-type structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, Figure 2, Figure 3 shows, the earth anchor of the present embodiment, the tension assembly 2 comprising tieback connection I 1 and be connected with tieback connection I 1, the connector II 22 that described tension group 2 comprises three tension unit 21 and is arranged in the middle part of tension unit 21, tension unit 21 is herein seamless steel pipe, and connector II 22 is the junction plate 221 be fixed on seamless steel pipe and the bolt 222 be fixed together by adjacent connection plates 221; During use, seamless steel pipe connects into bamboo raft type structure by the junction plate 221 at middle part and bolt 222.
The seamless steel pipe of the present embodiment can at φ 102mm, φ 121mm, φ 140mm, wall thickness is select in several specifications of 5 ~ 6mm, steel pipe earth anchor specification after composition is consistent with existing cement cable quadrant specification, certainly, tension unit 21 herein also can select the steel bar of other types can achieve the goal equally.
The tieback connection I 1 of the present embodiment be a similar in the boatswain chair of junction plate 221, boatswain chair is provided with drag-line connecting hole 11; This boatswain chair replaces the middle part that junction plate 221 is arranged on a seamless steel pipe, and the junction plate 221 remained on two seamless steel pipes all fixes with boatswain chair.
In the present embodiment, also comprise the covering 3 covered on tension unit 21, covering 3 is welded with the covering frame 4 that can block and embrace seamless steel pipe, by covering 3 is fixed on seamless steel pipe by covering frame 4, cover reliable, difficult drop-off; Covering 3 has sheltered from the gap between adjacent seamless steel pipe, increases the uplift resistance of earth anchor.
This programme also has other several variant, if tieback connection I 1 is the girder structure of 〦 type or+type structure, each tension unit 21 is all fixed on (as Fig. 4,5) on tieback connection I 1 by junction plate 221, or what fix in the middle part of each tension unit 21 is square contiguous block 223, tieback connection I 1 is hinged on a middle contiguous block 223 (as Fig. 6).
What finally illustrate is, above preferred embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although by above preferred embodiment to invention has been detailed description, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from claims of the present invention limited range.
