The buried structure comprises a pre-embedded box and a ground hook box, wherein the pre-embedded box comprises a fixing part and a supporting part surrounding the fixing part, and the fixing part and the supporting part form a cavity provided with an opening at one end; the ground hook box comprises a box body located in the cavity,a cover plate located on the outer side of the cavity and a limiting rod; an opening is formed in the cover plate opposite to the limiting rod, and the box body comprises a bottom plate which is opposite to the fixing part; and a screw is connected between the bottom plate and the fixing part, and the fixing part is provided with an expansion screw hole.

The invention discloses an electrolytic capacitor including a housing, the upper end of the housing is provided with a closing mechanism, the inner bottom end of the shell is fixedly connected with acapacitor element, the capacitor element includes a first sealed housing fixedly connected to a bottom end of the housing, An anode aluminum foil and a cathode aluminum foil are wound inside the firstsealed shell, and the anode aluminum foil and the cathode aluminum foil are isolated by electrolytic paper. An anode plate is fixedly connected to the anode aluminum foil, a cathode plate is fixedlyconnected to the cathode aluminum foil, and leads are fixedly connected to the upper ends of the anode plate and the cathode plate. The advantages are: The invention avoids the problem that the aluminum foil is broken down after the electrolyte is evaporated and reduced, thereby prolonging the service life of the electrolytic capacitor, protecting the positive electrode line and the negative electrode line, and pulling out the positive electrode line and the negative electrode line for use through a limiting ball when the electrolyte is needed, thereby avoiding the problem of extra searching by the worker and reducing the energy of the worker.

The invention discloses a method and a system for detecting the hollowness of the exterior facade of a house by means of an unmanned aerial vehicle, comprising the following steps: establishing a space coordinate system; selecting a detection point; parameter detection; preliminary comparison; The method and system of the present invention for detecting the hollowness of the exterior facade of a house by means of an unmanned aerial vehicle, firstly, by controlling the unmanned aerial vehicle to take pictures of the exterior of the house instead of manual work, which greatly reduces the difficulty of house detection for detection, and can also improve the detection Second, by comparing the three-dimensional image of the house with the external data of the house, the location of the error can be quickly obtained, which is convenient to obtain the location of the error, thereby reducing the scope of manual investigation; Comparing the acquired accurate 3D images with images of common objects in the database can further investigate the scope of the investigation, thereby increasing the difficulty and workload of the investigation.

The present application relates to a roof thermal insulation and waterproof structure and its construction method, belonging to the field of roof waterproofing, which includes a roof base, an insulation layer is fixedly arranged on the roof base, a first waterproof layer is fixed above the insulation layer, the insulation layer and A water diversion layer is fixedly arranged between the first waterproof layers. The bottom surface of the water diversion layer is even, and the top surface of the water diversion layer is provided with a sinking groove. The length direction of the groove is opened along the edge direction of the adjacent water diversion layer, and the sinking grooves are fixedly filled with water-absorbing cotton, and the top surface of the water diversion layer is inclined, and the inclination direction is set downward from the middle of the top surface of the water diversion layer to the sinking groove. The application has the effect of quickly finding the water leakage area of ​​the first waterproof layer.
