A construction device and method for a lateral bracing in an ultra-deep foundation pit with silt includes a first-layer lateral bracing member, a plurality of suspension rope systems and construction operation plates. The first-layer lateral bracing member is connected with the enclosing structure of the foundation pit. The suspension rope systems include saddles, slings and joists. The saddles are connected with the first-layer lateral bracing member, and the construction operation plates are connected with the joists.

A portable cofferdam system for isolating a working area from water such as a culvert. The portable cofferdam system generally includes a first sidewall and a second sidewall each having an interior side, an exterior side, an upper edge, a lower edge and a rear edge. A middle wall is connected to the sidewalls opposite of the rear edges of the sidewalls forming a substantially U-shaped structure. An opening formed between the rear edges of the first sidewall and the second sidewall to allow for positioning about or near the inlet of an object or area to be kept dry such as the inlet of a culvert.

A wale support module used to mount a wale on a soldier pile of a retaining wall, where the wale support module enables a groove defined between a soldier pile and a wale to be easily filled by a groove filling block, allows a groove filling block-side wale support or a pile support to pivot in response to the installation angle of an earth anchor to respond appropriately to the inclination of the wale so that the optimal anchoring force of the earth anchor can be exercised, can be removed and reused when a retaining wall is dismantled, and allows the stability of the installation of the wale to be increased by a reverse wale hanger.

A finishing assembly for a rail and post wall comprising: one or elongate capping members having longitudinal recesses for receiving a top of the wall and for installation therealong; and one or more post covers for installation over posts of the wall.

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.
