A shoring device for corners is shown and described. One of the models for the corner shoring device includes a first sidewall connected to a second sidewall, wherein the first sidewall and the second sidewall form an angled connection. A support wall is connected to each of the first sidewall and the second sidewall within the angle to prevent the sidewalls form closing in on each other.

Provided is a construction method for foundation pit support utilizing prefabricated large-diameter pipe pile, through this method the pipe pile can be sunk into a hole being drilled. The method applies to a large-diameter pipe pile being sunk. All of components, such as the prefabricated capping beam configured to fix all pile heads and the prefabricated waist beam configured to secure the pile bodies, can ensure the excellent fixture of the pipe piles during the construction of the foundation pit. This method has a good retaining and protecting effect when applied to construction of a deep foundation pit requiring large-diameter pipe pile. It can reduce the environmental impact caused by waste soil and mud discharge in traditional cast-in-place construction, and the use of prefabricated components decreased the construction period and improved the construction efficiency.

A measuring apparatus for measuring a structure comprises at least one measurement sensor configured to measure the structure, a bearing platform configured to carry the at least one measurement sensor and a control. The control is configured to specify at least one quality reference value for at least one characteristic of measurement quality, and further configured to adjust one or more parameters of the measuring apparatus which influence the at least one characteristic of measurement quality. An actual quality value is determined and approaches the at least one quality reference value as the one or more parameters are adjusted.

Embodiments of the disclosure provide a dredging apparatus, including a buoyant platform having an upper surface, a lower surface configured to float on a body of water, and an opening having a horizontal cross-sectional area and extending from the upper surface through the lower surface. A set of supports, mechanically coupled to the platform, is configured to maintain a position of the buoyant platform above a dredge site at a bottom of the body of water. A turbidity curtain, coupled to the platform using a plurality of telescoping members, surrounds at least the horizontal cross-sectional area of the opening. A bubble tube frame, coupled to the turbidity curtain and extending outwardly therefrom to surround the turbidity curtain, includes a plurality of outlets configured to emit bubbles into the body of water around a perimeter of the dredge site.

A cover band has a cover band body provided with a cover band arch portion corresponding to the outer peripheral surface of a steel pipe strut and a plurality of cover band through holes formed on the cover band body in such a manner as to correspond to a plurality of strut coupling holes. The cover band through holes have shapes of long holes extended in one direction and the extended direction of at least one of the cover band through holes is made to cross the extended direction of the other cover band through hole.

A blindside waterproofed building foundation system and method of forming the same are provided. The system includes a lagging wall, a monolithic waterproof layer adjacent to the lagging wall, and a foundation layer adjacent to the monolithic waterproof layer. The system and method provide a monolithic waterproofing layer that can remain adhered to a foundation surface even if the materials used to construct the lagging wall deteriorates, decomposes, or moves over time.

System and means soil stabilization and moisture control for building foundations including methods and systems for stabilization moisture in a site for building foundation by applying soil moisture stabilization material in various forms, a preferred stabilization material being a mixture of aluninosilicate Pozzolan mineral and granular material such as sand.
