The utility model discloses a pile foundation positioning device, and relates to the field of foundation pile foundation construction, the pile foundation positioning device comprises a concrete pile casing which is arranged in a hollow mode and used for a precast concrete pile body to pass through, the top end of the concrete pile casing is connected with a pile casing bearing platform which is integrally poured with the concrete pile casing, and the top end of the pile casing bearing platform is movably connected with a movable limiting cylinder. The movable limiting cylinder, the pile casing bearing platform and the concrete pile casing are arranged in a penetrating mode. A positioning sleeve is arranged on the outer wall of the movable limiting barrel and movably arranged on the outer wall of the movable limiting barrel in a sleeving mode, the bottom end of the positioning sleeve is connected with the top end of the pile casing bearing platform, and the top end of the positioning sleeve is used for making contact with the movable limiting barrel and stopping and limiting the movable limiting barrel. The positioning device is simple in structure and low in manufacturing cost, and can be used for guiding and positioning the precast concrete pile; in addition, the inclination direction of the precast concrete pile can be visually observed and judged through the positioning device, and the measurement frequency of on-site constructors is reduced.

The invention discloses a self-calibration and drift compensation method for an automatic underground water monitoring station, and the method comprises the following steps: 1, transmitting a reference measurement starting instruction to an underground bubble method device by an edge calculation gateway, forming a reference data pair by a bubble method water level reference value and a reference acquisition moment, and writing the reference data pair into a reference data cache region; 2, the edge computing gateway creates a state storage structure and a covariance storage structure; and step 3, the edge computing gateway reads a drift amount estimation value from the state storage structure as a drift compensation amount, and when a drift estimation standard deviation exceeds a set threshold, bubble method hardware reference acquisition is triggered. According to the invention, the problems of high manual calibration cost and lack of independent reference support in pure software estimation in the prior art are solved, so that a monitoring station can stably operate for a long time under an unattended condition and continuously output high-precision underground water level monitoring data.

The invention discloses a carbon emission reduction determination method based on a block chain, and relates to the technical field of carbon emission determination. The method comprises the following steps: S1, carrying out gridding processing on a monitoring area, and dividing the monitoring area into a plurality of small area units; s2, extracting a characteristic factor of each small area unit, and exporting a measurement model corresponding to each small area unit based on the characteristic factor; and S3, based on the measurement model of each small area unit, monitoring the three-dimensional space carbon emission of each small area unit through measurement equipment, and transmitting data to a block chain server. The monitoring area is divided into a plurality of small area units, each small area unit is monitored by adopting different measurement models, large-scale invalid monitoring is avoided, the energy-saving and environment-friendly properties are better, and the three-dimensional space carbon emission of each small area unit is monitored through the measurement equipment, so that the monitoring accuracy is improved. And the accuracy and the credibility of a carbon emission analysis processing result are improved.
