Workaround for ground anchor settling in clay

1

Ground anchors are used for fixing foundation pits’ fences, retaining walls and walls of underground structures, foundations of buildings, bottoms of docks and caisson, landslide slopes and slants, and so on. Ground anchor is a device made to transmit tensile loads from the anchoring structure to the bearing layers of the ground.

The anchor consists of three main parts: the well head, anchor bar and sealing.

Anchors can be divided by:

• the direction of traction – inclined and vertical;

• the method of making holes – drilling of the holes with casings, under the clay solution, with screw conveyer, immersion of casing by piling or indenting;

• by the method of anchor’s fixation – injection (the fixation is made by the supply of cement solution under overpressure) with bored widenings, cylindrical (hole is filled with a solution without overpressure);

• the material of anchor bars – from the reinforcement bars and wire-rope...

The Bush Ground Anchor

The Ground Anchor is a highly effective and portable self-recovery ground anchor solution when there are no alternatives. The anchors are very strong,easy to place and retrieve and don’t need knots, shackles or tools to connect the winch rope to.

Tailored for use with the Bush Winch in sand, mud and clay the Ground Anchor is one kit but includes two independent anchors. A recovery system that provides two anchors means that the winch load is automatically shared/halved and will hold where a single anchor point would not. Two anchors placed in tandem or independently also provide for a greater array of solutions otherwise not possible or strong enough from a single anchor point.

The Ground Anchors are screwed by hand into the ground (like an auger) and while doing this mated with a spade that is also pressed and pinned vertically into the ground. The auger and spade act together as a fixed unyielding point that resists the load far more...

Extension > Garden > SULIS > Implementation > Deck and Outdoor Structure Footings

Outdoor structures such as gazebos, decks, porches, arbors, and pergolas require strong footings as a base to build on. If the structure does not have a strong and stable foundation, the posts and beams attached to it may fail.

Footing Considerations

Outdoor structures are supported by a basic foundation called footings. Footings eliminate settling and slippage, and help protect posts and beams from direct contact with the earth. Posts and beams that come in direct contact with the earth will rot more quickly and ultimately weaken the structure.

Footings also prevent frost heave. If moist soil freezes, it will heave upwards causing an upthrust of the soil. The movement of the soil can push up on the posts and the structure attached to it. Small movements of 1/4 inch or less are acceptable. When movement of more than 1 inch occurs, there is often structural damage to the...

Change

It wasn't trendy, funny, nor was it coined on Twitter, but we thought change told a real story about how our users defined 2010. Unlike in 2008, change was no longer a campaign slogan. But, the term still held a lot of weight. Here's an excerpt from our Word of the Year announcement in 2010:

The national debate can arguably be summarized by the question: In the past two years, has there been enough change? Has there been too much? Meanwhile, many Americans continue to face change in their homes, bank accounts and jobs. Only time will tell if the latest wave of change Americans voted for in the midterm elections will result in a negative or positive...
