Description

A kind of compliance earth anchor

Technical field

The utility model relates to earth anchor technical field, is specifically related to a kind of compliance earth anchor.

Background technology

In ultra-high-tension power transmission line construction operation process, geographical conditions of often constructing are changeable, and when running into the geological conditionss such as sand ground, soft soil, clay, traditional earth anchor can not meet the requirement of safe construction; Tradition earth anchor needs first to dig ground anchor pit in use, and then earth anchor is embedded in underground, construction and excavation amount is large, labour intensity is high; And after having constructed, earth anchor reclaims difficulty, causes that efficiency is low, construction cost is high; On the other hand, traditional earth anchor is solid cylinder, causes earth anchor heavy, is not easy to the secondary transhipment between mountain region.

Utility model content

The utility model provides a kind of scientific structure, the compliance earth anchor that light and handy, stress performance is superior, practical and convenient.

The technical solution adopted in the utility model is, a kind of compliance earth anchor, comprises anchor point, anchor body, anchor leaf propelling movement axle; Described anchor body is the cylindrical structure of double layer hollow; Described anchor point is fixedly installed on anchor body lower end; Described anchor leaf pushes axle and is slidably arranged in the internal layer cylinder of anchor body, and lower end is hinged with at least one group of extensible anchor leaf; Often organize anchor leaf and have three blades, anchor body is provided with the window opening corresponding with blade stretching for anchor leaf; Described anchor leaf pushes axle top and is also provided with steel column; Steel column diameter is less than anchor body internal layer cylinder, and upper end exceeds anchor body upper surface.

As preferably, described anchor body is in the window nibs of same level, is uniformly distributed on anchor body.

As preferably, described anchor leaf has two groups, and window opening corresponding with it divides two-layer arrangement, is staggeredly arranged between upper and lower two-layer window nibs.

As preferably, described anchor body upper part external surface is fixed with three draw rings; Draw ring is fixed on the same cross section of anchor body, and angle is 120 ° each other.

The beneficial effects of the utility model are:

(1) the utility model adopts the cylindrical structure of double layer hollow, and earth anchor is lightly flexible;

(2) the utility model arranges extensible anchor leaf, practical and convenient, and anchor leaf can increase the fixed performance of anchor;

(3) the utility model top arranges draw ring, can be used alone and also can combinationally use simultaneously.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figure 1, 2, a kind of compliance earth anchor, comprises anchor point 1, anchor body 3, anchor leaf propelling movement axle 4; Anchor body 3 is the cylindrical structure of double layer hollow; Described anchor point 1 is fixedly installed on anchor body 3 lower end; Anchor leaf pushes axle 4 and is slidably arranged in the internal layer cylinder of anchor body 3, and lower end is hinged with at least one group of extensible anchor leaf 2; Often organize anchor leaf 2 and have three blades, anchor body 3 is provided with the window opening corresponding with blade stretching for anchor leaf 2; Anchor leaf pushes axle 4 top and is also provided with steel column 6; Steel column 6 diameter is less than anchor body 3 internal layer cylinder, and upper end exceeds anchor body 3 upper surface.

Anchor body 3 adopts double layer hollow cylindrical structure, can close between upper surface two hollow circular cylinder, and soffit is closed by anchor point 1 upper surface, avoids some soil in work progress to wait impurity pollution earth anchor, can alleviate the weight of earth anchor, be easy to carry; Anchor leaf adopts extensible structure, expands out in use, can increase the fixed performance of earth anchor; Easily hammer force can be delivered to anchor point by steel column 6, by earth anchorage, and anchor leaf can be promoted simultaneously push axle 4 anchor leaf is expanded out.

The window opening that described anchor body 3 is corresponding with one group of anchor leaf 2, is on the same cross section of anchor body 3, and is uniformly distributed on anchor body 3; Window nibs is uniformly distributed and bed knife can be made more even; Described anchor leaf 2 has two groups, and window opening corresponding with it divides two-layer arrangement, is staggeredly arranged between upper and lower two-layer window nibs; Double-deck anchor leaf 2 structure adopted in the present embodiment, but the group number of anchor leaf 2 is not limited to two-layer, can regulate the group number of anchor leaf 2 according to actual needs; Described anchor body 3 outer surface of upper is fixed with three draw rings 5; Draw ring 5 is arranged on the same cross section of anchor body 3, and angle is 120 ° each other; Draw ring 5 is set, can conveniently use with other association of anchor block, or connect other fastening devicess, draw ring 5 arranges three, wherein any two can be connected to form quincuncial pile with two ground anchor pegs, for transmitting electricity, distribution line executes man-hour requirement by the situation of larger pulling force, and another draw ring 5 may be used for fixing temporary guy or wind rope.

Earth anchor entirety adopts high strength steel or alloy material etc., and hardness and the larger material of intensity, can be wear-resistant, and not yielding in use procedure.

When sand ground or soft geology use, earth anchor becomes about 75 ° angles with ground, hammering steel column 6, pushes axle 4 and expands out by anchor leaf 2, increase the crystallized ability of earth anchor by anchor leaf; When needing larger bed knife, three association of anchor block can be adopted to use, be interconnected between earth anchor by draw ring 5, one of them earth anchor adopts double-hook wire grip and other two draw rings 5 to be connected, and makes it form an entirety by regulating double-hook wire grip.

The utility model, when being used to complete, only needing left and right to knock anchor body 3 upper end, makes earth anchor be loosening state, i.e. retrieval; The utility model scientific structure, stress performance be superior, easy for installation, it is reliably stressed to connect, and mounting means flexibly, be widely used, be specially adapted to the poor sand ground of mechanical property or soft geology execution conditions.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
