This disclosure relates to alignment devices and methods, e.g., for multi-legged structures.
Constructing a multi-legged utility tower, for example, requires the use heavy machinery in order to align and drive the legs of the tower into the ground. However, such heavy machinery is not equipped for constructing these structures in environments where the ground is soft or frequently saturated, such as wetlands, or areas of heavy flooding. Using conventional devices and methods in these environments is not practical and adds significant time and financial cost to construct the tower.
Such conventional methods and systems have generally been considered satisfactory for their intended purpose. However, there is still a need in the art for improved alignment devices and methods. The present disclosure provides a solution for this need.
In accordance with at least one aspect of this disclosure, an alignment device for assembling a structure having two or more legs can include a base configured to support a pile driver for pile driving at least one of the two or more legs, and a plurality of alignment structures configured to define an alignment opening, connected to the base, and extending at least partially laterally from the base. The plurality of alignment structures can be configured to receive a respective leg of the two or more legs to allow the two or more legs to be positioned relative to each other.
Each alignment structure can further include one or more alignment support members connected to each alignment structure and extending into and/or over the alignment opening, and each alignment support member can be configured to contact a leg disposed in the alignment opening. The one or more alignment support members can be complementary to surface of a respective leg and can be positioned to contact the respective leg in flush contact. The one or more alignment support members can be positionably mounted to each alignment structure to allow each alignment support member to be positioned relative to a respective leg disposed within the alignment opening.
In certain embodiments, the plurality of alignment structures can include a complimentary shape to the two or more legs. For example, each alignment structure can be complementary to a caisson having a substantially polygonal shape. In certain embodiments, each alignment structure can have a dodecagon.
The base can form a substantially planar shape, and the alignment opening of each alignment structure can include an opening planar vector that can be substantially parallel to a base planar vector of the planar shape of the base. In certain embodiments, the substantially planar shape can be a square shape.
The base can further include a support frame and a platform supported by the support frame. The base can include a first side and a second side that can be detachably connected to each other along a midline.
The device can also include at least one pair alignment baffles configured to receive a portion of a pile driver on the platform. Each alignment baffle can be configured to receive a foot of a pile driver and/or are complimentary to a shape of a foot of a pile driver. The at least one pair of baffles can be at least one inch in height. The device can include a plurality of connection points that can be configured to connect to a lifting device for lifting and/or transport of the alignment device.
In accordance with at least one aspect of this disclosure, a method can include constructing a structure having a plurality of legs using an alignment device configured to align each leg relative to each other. The method can also include disposing an alignment device onto a surface. Disposing the alignment device can include lowering the alignment device from a helicopter, for example. The method can include disposing a pile driver onto the alignment device. Disposing the pile driver can include lowering the pile driver from a helicopter, for example.
In embodiments, the method can also include placing a first leg of the structure into a first alignment structure of the alignment device, and pile driving the first leg of the structure into the surface using a pile driver supported by the alignment device. The method can include placing a second leg of the structure into a second one of the alignment structures of the alignment device. The method can include turning the pile driver to interact with the second leg and/or to align the pile driver with the second one of the at least one alignment structures, and pile driving the second leg of the structure into the surface using the pile driver.
In accordance with at least one aspect of this disclosure, a method can include constructing a multi-legged utility tower having a plurality of legs on wetland using an alignment device configured to rest on the wetland surface to align at least two of the plurality of legs. The multi-legged utility tower can be an electrical transmission structure, for example.

Those having ordinary skill in the art understand that any numerical values disclosed herein can be exact values or can be values within a range. Further, any terms of approximation (e.g., “about”, “approximately”, “around”) used in this disclosure can mean the stated value within a range. For example, in certain embodiments, the range can be within (plus or minus) 20%, or within 10%, or within 5%, or within 2%, or within any other suitable percentage or number as appreciated by those having ordinary skill in the art (e.g., for known tolerance limits or error ranges).
The articles “a”, “an”, and “the” as used herein and in the appended claims are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article unless the context clearly indicates otherwise. By way of example, “an element” means one element or more than one element.
The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e., “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.”
Any suitable combination(s) of any disclosed embodiments and/or any suitable portion(s) thereof are contemplated herein as appreciated by those having ordinary skill in the art in view of this disclosure.
The embodiments of the present disclosure, as described above and shown in the drawings, provide for improvement in the art to which they pertain.
