Various embodiments of the disclosure enable installation of a utility scale solar array or other project requiring a site survey and survey markers at every ground penetration to be replaced with survey markers only at the end of each row. In addition, machine mast alignment for driving H-piles with an impact or vibratory hammer, or for driving screw anchors, helical anchors or other foundation with a rotary driver to be automated with the use of range finding lasers to orient the driving mast in X, Y and Z as well as pitch, roll and yaw based on range finding laser measurements.

In a machine for driving screw anchors and other foundation components, a desired embedment depth is calculated based on a minimum required embedment depth, work point height and length of available upper leg sections. Once calculated, the machine automatically drives the screw anchor to the depth so that one of the available upper leg lengths will fit between the driven screw anchor and apex truss hardware. If uplift is detected during driving, the machine will add additional embedment depth. In-situ validation of driven screw anchors may be performed after the embedment depth is reached.

A method for installing a pile in a cavity of a soil layer is disclosed. The method includes drilling the cavity in the soil layer using a drilling assembly, applying pressure with the drilling assembly during drilling to an interface portion of the soil layer that is adjacent to the cavity, sensing pressure data of the interface portion during drilling, and transferring the pressure data to a controller during drilling. The method also includes determining pile capacity data of the pile with the controller during drilling based on the pressure data, transferring the pile capacity data during drilling, and controlling the drilling assembly based on the pile capacity data during drilling.

A method and system determines in real time the bearing capacity of a foundation tamped by a high-speed hydraulic tamper. Four wireless acceleration sensors are arranged uniformly along tamping plate edges, sensor position tamping points are determined; the soil is tamped, the plate peak acceleration slows, tends to, and reaches stabilization in a range, a relationship curve between the tamping number and plate peak acceleration is determined; different loads are applied to the foundation to obtain corresponding settlements, coordinate axes are established, points are drawn according to each test data group and sequentially connected with a smooth curve to obtain a settlement-load curve, and the curve is fitted; a tamping number and foundation bearing capacity relationship is obtained; the two relationship curves are combined to obtain a relationship curve, and the foundation bearing capacity magnitude at a certain moment during the tamping operation is determined by using the acceleration index.

A closed-loop feedback-control system for a screw anchor driving machine that uses a programmable logic controller (PLC) and array of sensors providing real-time data to control an automated screw anchor driving operation relying on a rotary driver, a crowd motor applying downforce to the rotary driver and a tool driver extending a tool through the rotary driver and screw anchor to drive screw anchors to a target depth.

The invention relates to a manhole element (a shaft element) (1) for forming at least a portion of a manhole structure (a shaft structure) (2), which manhole element is comprised of a base body (3) delimiting a hollow space; wherein at least one detection device (4), which is designed to detect and determine at least one detection variable, as well as an associated transmission device (5), which is designed to transmit the detection variables acquired by the detection device (4) to at least one communication partner, are integrated into the base body (3).

A system including an active ventilation device and a system controller. The active ventilation device is installed in an underground vault and generates an exhaust flow from the vault having an exhaust rate. The system controller is configured to determine that a reading received from a selected gas sensor indicates that a manhole event is occurring, and instruct the active ventilation device to change the exhaust rate when the reading indicates that the manhole event is occurring. The system controller is configured to receive at least one sensor reading after the exhaust rate has been changed, determine whether the selected gas sensor is exhibiting drift based at least in part on the sensor reading(s), and perform an action when the system controller determines the selected gas sensor is not exhibiting drift. The action includes notifying a user and/or instructing the active ventilation device to alter the exhaust rate.

The present invention discloses a system for bridge scour multi-source monitoring, including an intelligent monitoring system, a data industrial personal computer, a 5G remote communication transmission system and a remote scour depth evaluation center. The intelligent monitoring system consists of three subsystems including a high-frequency real-time bridge dynamic characteristic monitoring system, an adjustable sound velocity underwater depth monitoring system and a scoured seabed soil pressure change testing system, which are coupled with one another to carry out triggering control to acquire lateral pile data, thereby forming a multi-source bridge local scour real-time sensing monitoring system, and realizing integration of clock synchronization, dynamic control of scour environment conditions, contact sensors and non-contact sensors. The system carries out integrated monitoring on a scour interface, seabed silt scour and deposition as well as bridge dynamic response, and a structural scour depth evaluating method provides bases for bridge maintenance.

A robotics-assisted foundation installation system is provided in which data reporting the X, Y, and Z positions of foundation column tops are sent from a total surveying station to a grid control system. The grid control system receives the data and associates specific data with specific columns in an arraythe grid. The grid control system compares the actual positions of the columns in the grid to target positions that were determined based on the requirements of the structure to be supported. After determining differences between the actual positions and the target positions, the grid control system sends instructions to column positioning tools associated with the individual columns. Actuators in a column positioning tool are directed by the grid control system to adjust the position of the associated column. Once the live streamed data confirms that each column is in the proper position, the columns are fixed in place.

The invention relates to a construction method, in which an excavation pit is produced in the ground and in the excavation pit foundation elements are produced at predetermined working points with at least one working apparatus. According to the invention provision is made in that in a computer unit the dimensions of the excavation pit, the working points and the dimensions of the at least one working apparatus are entered and in that in the computer unit a required workspace for the at least one working apparatus and an open space in the excavation pit are determined automatically.
