A method of reinforcing the tower base in existing guyed towers. A guyed tower is a tower supported by a base and guy cables. The tower's foundations are Base and Deadman anchors. The base is an isolated spread footing which is pier and pad or pile foundation. This method of reinforcing is a new mechanism to transfer part of the download on base to an alternative mat foundation.

The reason of using this mechanism is that the soil underneath the tower base is getting high stresses above its limit. The soil is getting overstressed due to some reasons that it happens frequently.

The standard procedure is before building any tower, the Geotechnical engineer does test boreholes at the proposed location of the tower foundations (Base Deadman Anchors). The geotechnical engineer provides the soil report with soil parameters at each borehole. The structural engineer designs the guyed tower and get the download on the tower base to design the spread footing (or pile). The download is the result of the dead load (tower own weight, mounts, antennas, microwave dishes, cables & equipment) and live load (wind & ice). The structural engineer designs the base to transfer the download from the tower to the soil safely based on the information that was given by the geotechnical engineer. In the future, if no change in loading, then the base will function well as designed, however the client always changes the dead load (antennas, microwave dishes, cables & equipment) and this is due to the fast-growing telecom technologies and the country needs. So, in most cases the base requires reinforcing.

The nonstandard procedure is to design the tower base, based on normal dry soil. Normal dry soil is a soil with average soil parameters values, this could happen due to short notice given by the client to the geotechnical engineer and the geo couldn't make it before designing the base. In this case the structural engineer designs the base with some assumed soil parameters and increasing the download to cover the absence of soil report (multiply download by factor more than 1.0, usually 1.20). Later after receiving the soil report, sometimes the soil parameters are weaker than the parameters that was used by the structural engineer. Here, the engineer must find the stresses on soil underneath the tower base and compare it with the soil report, if it was above the soil limit then reinforcing the base is required.

Something else which is the ice thickness, and this is defined by the ANSI-TIA-222. Telecommunications Industry Associations reviews the ice records and publish new list of the past 50 years of ice thickness. Also, they provide some changes on ice

An anchoring device for supporting a post from a support surface. The anchoring device comprises a base, at least one stanchion extending from the base, and a plate attached to the stanchion opposite the base. A plurality of side supports is included with each side support attached to and extending from the base. The side supports are also attached to the plate and extend past the plate. First and second guides are included with each guide attached to the plate and each side support. Each guide extends away from the base.

A semi-finished part for a foundation of a tower construction, in particular of a wind turbine tower, comprising at least two semi-finished part foundation segments, which each have an outer delimitation element and a reinforcement, which is connected to the outer delimitation element and comprises struts protruding from the outer delimitation element, wherein: the outer delimitation elements of the semi-finished part foundation segments form an outer edge, which delimits an interior to be later filled curable casting material; and the reinforcements of the semi-finished part foundation segments extend from the outer edge into the interior.

This pile installation system for an offshore foundation construction includes a main body, a movable part and a first means for attaching the main body to a frame of reference. This frame of reference is configured to act as a counterweight. It further includes a second means for attaching the movable part to a pile to be installed, and the movable part may be moved, with respect to the main body, in translation about the direction of an insertion axis.

A method is for generating a freeroom for a mast element in a ground. The method includes the steps: a) drilling a first annular recess into the ground, the first recess having: a first diameter; and a first depth; b) drilling a second annular recess in the ground, the second recess being arranged to receive the mast element, and the second recess: having a diameter which is smaller than the first diameter; having a second depth which is larger than the first depth; surrounding a first core of the ground; and being surrounded by the first recess; wherein there is, defined between the first recess and the second recess, a second core which can be removed to generate a freeroom.

Automated systems and methods for drilling while driving foundation components are provided. In some cases, based on detected conditions, it may be desirable for an automated controller to change the bore diameter of a drill bit during a drilling and driving operation. The need for this may be determined based on monitoring the output of one or more sensors related to one or more corresponding performance metrics of the drilling and driving operation.
