Abstract
A screw anchor is applied to the construction foundation projects of power, telecommunication and other fields, which consists of a foundation bearing platform, an anchor rod and screw anchor sheets; the screw anchor sheets are arranged on the different sections of the anchor rods, each anchor rod is provided with 1 to 18 screw anchor sheets, the anchor rod which is provided with screw anchor sheets are arranged below the foundation bearing platform and the anchor rod which is arranged below the foundation bearing platform is 1 or more; the utility model changes the features of the foundation of the construction and increases the uplift force, the down force and the horizontal force which are supported by the foundation, the structure is simple, the usage is convenient; the utility model can not only be drilled manually, but can also be drilled mechanically, the cost is saved, the construction period is shortened, the environment is protected and the utility model occupies less land.
Description
Affiliated technical field
The utility model is applied to the foundation of civil work engineering in fields such as electric power, communication.
Background technology
In the foundation of civil work engineering in fields such as electric power conveying, communication, rely on Screw Anchor that the brandreth or the electric pole of power line are fixed in the soil, in order to change basic characteristic, uplift force, downforce and the horizontal force that the basis bears increased, adopt Screw Anchor under weak geological conditions than other form base section investment-saving and duration.Existing Screw Anchor, the Screw Anchor of having only machinery to creep into, and the Screw Anchor of manually not creeping into.The Screw Anchor volume that this machinery creeps into is big, complex structure, cost height, take up an area of manyly, especially is unsuitable for constructing under the geographical environment of complicated condition.
Summary of the invention
Complex structure, the volume that exists at the existing machinery Screw Anchor is big, cost is high and problem such as construction inconvenience, the utility model provide a kind of can be manually or the light-duty machinery Screw Anchor of creeping into.
The utility model is made up of foundation platform, anchor pole and Screw Anchor sheet, foundation platform has two kinds of concrete structure and steel work, anchor pole is with making through antiseptic steel pipe, the anchor pole external diameter is 25mm-260mm, wall thickness is 2mm-45mm, highly be 1.5m-28m, the bottom of anchor pole is taper, and the brill degree is 10 °-180 °.Different sections at anchor pole are equipped with the Screw Anchor sheet, every anchor pole can be adorned 1-18 Screw Anchor sheet, and Screw Anchor sheet external diameter is 230mm-2400mm, and pitch is 20mm-1200mm, the Screw Anchor sheet is equidistant or not equidistant installation on anchor pole, and the Screw Anchor sheet is welded on the anchor pole or with anchor pole and is connected with bolt.The anchor pole that has the Screw Anchor sheet is contained under the foundation platform, when foundation platform is concrete structure, anchor pole is connected and fixed by reinforcing bar and the foundation platform that is welded in the top, and when foundation platform was steel work, the anchor pole top was welded on the foundation platform or with foundation platform and is connected with bolt.As required, being contained in the anchor pole that has the Screw Anchor sheet below the foundation platform is one or many, and when many anchor poles were housed below the foundation platform, anchor pole is general below foundation platform to become reasonable Arrangement.
The utility model has changed the structure base characteristic, and uplift force, downforce and horizontal force that the basis is born increase, and be simple in structure, easy to use, both can manually creep into, and also can creep into by machinery, saves cost, shortens the construction period, and the protection environment accounts for the soil less.
