The friction ground anchor is reasonable in design, can be arranged in a gravity friction mode, is of a non-embedded type, safe, reliable, simple, convenient, easily implemented and remarkable in economic benefit, and can replace a traditional deep-dug ground anchor to solve the problem that special zones such as sand, mire, rock and the like cannot be excavated.
Description
Technical field
The utility model belongs to shaft tower backguy earth anchor, is specifically related to a kind of friction earth anchor that is applied to the non-embedded type of extreme terrain.
Background technology
Earth anchor is used for fixing the stabilization and reinforcement of stringing shaft tower in transmission line of electricity sets up, traditional earth anchor need ground excavation and buried go under.But in the network of waterways, landform such as mire, desert, mountain region use, required freight volume is big, the excavation working time is long, recruitment is many, safety factor is low, also can cause large-area vegetation destruction, the occupation of land reimbursement of damages is big.
In more special landform, for example difficult excavation areas such as pools zone, swamp land, drift-sand, drift sand, the river bend use the flush type earth anchor that bigger difficulty is arranged.More do not allow large tracts of land excavation to destroy the urban renewal area on ground, construct and that cost is set is too high.
The utility model content
It is a kind of reasonable in design that the utility model provides, the friction earth anchor that can utilize the gravity friction mode to be provided with, this friction earth anchor is the non-embedded type earth anchor, safe and reliable, simple and easy to do, remarkable in economical benefits, alternative traditional deep-cut that earth anchor solves special areas such as sand ground, mire and rock can't excavate problem.
The technical scheme that the utility model adopted is as follows:
A kind of friction earth anchor, it is characterized in that described friction earth anchor comprises tractive unit and heavy burden portion, it is characterized in that described heavy burden portion is a load-bearing steel structure body, described tractive unit has an oblique wedge-shaped part that extends down, this wedge-shaped part connects a framework, and framework is provided with towing point; Setting is articulated and connected between described heavy burden portion and tractive unit.
In the specific embodiment, the trussed construction that described load-bearing steel structure body is made up of angle steel, fixing between described angle steel by bolt or welding.
In one embodiment, the framework of described tractive unit is the rectangle framework that an angle steel is formed, and between a sidepiece of a sidepiece of this rectangle framework and described load-bearing steel structure body a plurality of hinge members is set.
In another embodiment, the other side of the framework of described tractive unit is provided with towing point, and this towing point is positioned at the middle part of this framework sidepiece, and this towing point is a U type ring.
Again in the embodiment, described wedge-shaped part is made up of the oblique extension in framework lower surface of tractive unit and two angle steel that are fixed on the angle steel that cross at least, and described at least two angle steel are by the oblique extension of relative opposite side of the hinged side direction framework of framework and load-bearing steel structure body.
This friction earth anchor is the non-complete flush type earth anchor that utilizes the mode of gravity friction to be provided with, and tractive unit and heavy burden portion can form by angle steel.Whole friction earth anchor can adopt two hinged closed-in constructions, and the front end of friction earth anchor is a tractive unit, about about 50cm, towing point is set on the framework of tractive unit is connected with backguy under the wedge-shaped part that the framework below of tractive unit is provided with can be imbedded.The rear end of friction earth anchor is a heavy burden portion, and this heavy burden portion can also can fix with welding manner with bolt between every angle steel for the steel framework that contacts with ground of angle steel composition.According to stressed difference, can adjust the width and the length of this heavy burden portion.In heavy burden portion is which can arrange weights such as sandbag, regulates the frictional force of friction earth anchor.
In the work progress of organizing tower and stringing, can at first test calculating according to the situation and the geological conditions at scene.By regulating the stressed of earth anchor that rub of how much controlling of sandbag.The sandbag of placing on the friction earth anchor can be gathered materials on the spot, and the sand of job site just can directly pack.Construction also can directly be backfilling into the job site after finishing, and can the environment of job site not damaged.
The beneficial effects of the utility model are, this friction earth anchor is reasonable in design, can utilize the setting of gravity friction mode, this friction earth anchor is the non-embedded type earth anchor, safe and reliable, simple and easy to do, remarkable in economical benefits, alternative traditional deep-cut that earth anchor solves special areas such as sand ground, mire and rock can't excavate problem.
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is another structural representation of the utility model specific embodiment.
The specific embodiment
As depicted in figs. 1 and 2, this friction earth anchor is made up of heavy burden portion 10 and tractive unit 20 two parts, and the gross area is: 2.97 * 1.3=3.861 square metre.Heavy burden portion 10 is a load-bearing steel structure body, and the trussed construction that load-bearing steel structure body is made up of angle steel 11 can be fixing by bolt or welding between angle steel.Tractive unit 20 is positioned at front end, tractive unit has an oblique wedge-shaped part 23 that extends down, this wedge-shaped part connects a framework 21, and this framework is the rectangle framework that an angle steel is formed, and between a sidepiece of a sidepiece of this rectangle framework and load-bearing steel structure body a plurality of hinge members 11 is set.The other side of the framework of tractive unit is provided with towing point 22, and this towing point is positioned at the middle part of this framework sidepiece, and this towing point is a U type ring.Wedge-shaped part 23 is made up of the oblique extension in framework lower surface of tractive unit and two angle steel that are fixed on the angle steel 24 that cross at least, and these at least two angle steel are by the oblique extension of relative opposite side of the hinged side direction framework of framework and load-bearing steel structure body.
This friction earth anchor generally is used in the flush type earth anchor inconvenient landform is set, as difficult excavation areas such as pools zone, swamp land, drift-sand, drift sand, the rivers bend.It is 50KN that the design of this friction earth anchor allows pulling force, can use pulling force and backguy determine heavy burden weight to the ground angle as the friction earth anchor is maximum according to friction earth anchor stress condition during use, can by stress curve or in following table 1 correspondence look into and get.When for example backguy was to 30 ° of ground angles, friction earth anchor maximum weighted was that 30KN checks in mound weight and should be not less than 2.25 tons.But mound forms and bears a heavy burden in heavy burden portion.Can or weave packed sand with straw bag, mound is built on the earth anchor truss, the gap is healed better little.Also can pile up to the enclosure wall that requires height along the angle steel outer rim, sand, soil are tamped in inside then, and compacting is extremely near the undisturbed soil state.
When calculating the mound volume, unit weight can be by 1.4 tons/cubic metre, safety coefficient K=1.5;
Cumulose soil weight=area * mound height * native unit weight;
The simplification calculating formula of mound height is: mound height=cumulose soil weight/5.4;
