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 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.

A bell hole box with an open bottom for protecting construction workers from wall cave-in when working below a surface of the Earth may utilize two, opposing, generally concave walls with generally straight panels portions. The two walls may be connected using multiple spreaders that are pinned or connected to each of the two, opposing walls. Each longitudinal end of the bell hole box is open to permit passage of a pipeline through it. Numerous vertical guard posts may be connected around a top frame rail and joined together with chains. The bell hole box may be lifted in and out of a hole with mounted lifting hooks.

The trench shoring apparatus includes first and second side panels connected in a parallel spaced-apart configuration by a connecting rod pivotally connected to one end of one or more pairs of lateral arms. The other opposite end of the one or more pairs of lateral arms is hingedly connected to the side panels, such that translational movement of the connecting rod in a direction parallel to the side panels causes the spaced-apart panels to move between retracted and extended parallel spaced-apart configurations.

An end frame includes a guide having a channel therethrough for receiving a sheet piling and a pair of hangers for hanging the end frame from a spreader of a trench shield. The end frame hangs from the spreader and bears against the adjacent ends of the sidewalls of the trench shield to provide a channel through which sheet piling can be inserted and stabilized as the sheet piling is driven into the soil adjacent to the end of the trench shield. The sheet piling and the end frame prevent unwanted cave-ins of soil into the workspace between the sidewalls of the trench shield without imparting unwanted buckling forces to the midsection of the spreader from which the end frame hangs. The hangers may be rigidly coupled to the guide or they may be coupled to the guide through chains, cables, straps or through pivoting linkages.
