The invention belongs to the technical field of steel cofferdam displacement monitoring, and specifically discloses a deep-water bottomless double-wall steel cofferdam construction displacement monitoring system. The system performs multi-source displacement monitoring on a lowered cofferdam section during a trial monitoring period, and simultaneously performs water level and flow rate monitoring, and uses mutation analysis of displacement to identify environmental impact monitoring sources, so that in subsequent displacement monitoring, the monitoring results of water level and flow rate are combined to select effective monitoring sources for precise displacement monitoring. This process realizes effect verification before displacement monitoring is implemented, and ensures the accuracy of displacement data to the maximum extent. At the same time, when using the displacement monitoring results for analysis, the displacement guidance analysis of the lowered steel cofferdam section is performed by identifying the displacement monitoring points, and combining the layout positions and displacement directions of these monitoring points. This process realizes the in-depth utilization of displacement monitoring data, can provide targeted guidance for displacement correction, and is conducive to improving correction efficiency and correction effect.

The present application relates to the technical field of boiler integrated heat supply, and discloses a gas-electric dual-purpose skid-mounted boiler integrated heat supply device, which comprises a heating furnace body, an oil inlet end and an oil outlet end fixedly communicated with the heating furnace body, and a water inlet and a water outlet fixedly communicated with the heating furnace body; a start motor drives a reciprocating screw rod to rotate; a sleeve ring reciprocates along the screw rod shaft; each push ring is driven to synchronously slide up and down along the outer wall of a vertical smoke pipe; the inner edge of the push ring always keeps sliding contact with the outer wall of the smoke pipe; in the process of reciprocating sliding, the push ring can continuously scrape off the scale layer adhered to the outer surface of the vertical smoke pipe, effectively inhibits the accumulation and thickening of the scale on the heat exchange surface of the smoke pipe, thereby avoiding the attenuation of the heat transfer efficiency caused by the increase of the scale layer thermal resistance, keeping the apparent heat transfer coefficient between the vertical smoke pipe and the water medium stable in long-term operation, significantly prolonging the efficient operation period of the heating furnace body under the condition of no cleaning, and reducing the excessive consumption of fuel caused by scaling.
