Combined LED light source for reducing cannibalism rate of garrupa and application thereof

The invention provides a combined LED light source for reducing the cannibalism rate of garrupa and application thereof. According to the method, the purpose of reducing the cannibalism rate is achieved by combining the environment control technology and an accurate feeding manner by means of the environment control technology of creating a specific light environment, the illumination time and the illumination intensity in an industrialized garrupa aquaculture workshop. The method is specially developed according to the avoidance tendency of main garrupa culture species such as saddletail groupers, pearl gentian groupers and epinephelus septemfasciatus to the specific spectra, light intensity and illumination period and the appetite regulation and control rules of epinephelus coioides juveniles. By means of the method, the cannibalism of the garrupa can be effectively restricted, and economic losses caused by cannibalism during the intermediate culture period of industrialized garrupa seedlings are remarkably decreased. Moreover, operations is easy and convenient, the automation degree is high, the health, safety, energy conservation and environment protection are realized, and the method has high application and popularization value.

Construction method of anchor rod static pressure pile

The invention relates to a construction method of an anchor rod static pressure pile. The construction method specifically comprises the following steps that (1) a pile position is determined; (2) hole perforating is carried out; (3), a pile hole is checked and cleaned; (4) a pressing pile reaction frame is installed; (5) a pile is transported; (6) hoisting alignment and perpendicularity calibration are carried out, wherein the anchor rod pile frame is used for lifting the pile, and the perpendicularity of the pile is calibrated; (7) pile pressing and pile connecting are carried out, wherein the pile is pressed into positions with set depth by using a lifting jack in a sectionalized mode and taking anchor rods as a guide, starting from the second section of the pile, all sections of the pile are welded together before being pressed into the positions; and (8) pile pressing is finished, the pile is conveyed to the designed elevation, and after the pressing-in is completed, the pile holepile is cleaned, after electric welding is finished and the pile passes acceptance inspection, the pile is pressed to the elevation of a bottom plate of a basement after being cooled for 8 minutes, then the site is cleaned, and the frame is moved to and installed at another pile hole. According to the construction method, a building load is transferred to the deep stratum through the anchor rod pile, so that additional stress of a shallow layer soil body is reduced, then the compression deformation of the shallow layer soil body of a reinforced part is reduced or stopped, and therefore, settlement or floating of a building is stabilized.
