The present invention is depth detecting method for plastic drainage plate, and the depth of plastic drainage plate is measured via measuring resistance based on DC bridge principle. Two metal wires capable of forming passage are first set inside plastic drainage plate, and the material coefficient of plastic drainage plate and the construction technological index are then determined via indoor test and in-situ measurement. During construction, the metal wires are connected in the bottom and the plastic drainage plate is set into required depth, the resistance of the metal wire is measured with depth measuring instrument, and the practical depth of the plastic drainage plate is finally calculated. Compared with available technology, the present invention has high measurement precision and fast detection speed, and may be used widely in the soft foundation treating engineering with plastic drainage plate.

The invention provides an antiseismic product, and relates to an antiseismic building. Because 18 times of earthquakes above M7 and 1 to 2 times above M8 occur on the earth each year, people are in dire need of various antiseismic products. The invention provides the building capable of adopting automatic prevention measures to resist earthquakes. The entire building is designed by adopting the principle of tumblers; therefore, the building is just like a tumbler and does not collapse in a new environment when an earthquake causes ground cracks, sinking or land slides. Moreover, because the groundwork of the building is a solid hemispheroid or a laid down semicylinder, a cambered surface at the bottom can disperse the impact force of an earthquake on the building and changes the direct of the impact force, thereby ensuring that earthquake waves spread toward the periphery of the building; meanwhile, the earth generates powerful attraction on the inclined solid groundwork to force the building to recover and maintain erection or an inclined but not collapsed state, thereby guaranteeing the safety of human life and property. Therefore, the antiseismic building is suitable for schools, factories, city buildings and residential buildings and is particularly suitable for top-grade villas and scenic spot construction.

The invention relates to a U-shaped device for steel reinforcement framework processing. The U-shaped device comprises a base and a U-shaped table board. The U-shaped device has the advantages of being simple in structure and convenient to use. When the U-shaped device is in use, a steel reinforcement to be processed is placed on a bearing plate so that the steel reinforcement to be processed canbe fixed well through cooperation of a matching plate to facilitate placing and position of the steel reinforcement to be processed while the bearing plate well bears the steel reinforcement to be processed, operation of construction personnel can be simplified, operation workloads of the construction personnel can be relieved, and then the construction personnel can assemble steel reinforcementsand semi-finished steel reinforcement products or semi-finished reinforcement framework products into reinforcement frameworks which can be taken and used instantaneously. The production quality of unified reinforcement frameworks can be controlled easily. Moreover, the U-shaped device can also output the reinforcement frameworks at the construction location for direct use. Accordingly, the requirements for the construction personnel are reduced, the construction quality of the reinforcement frameworks is effectively improved, the operation time of a construction working face of reinforced barengineering is shortened, and the construction speed is increased. Moreover, finished products can be subjected to casual inspection and acceptance inspection conveniently, the phenomenon of cheatingon workmanship and materials during reinforced bar engineering is avoided, and the construction quality is ensured.

The invention discloses an environment-friendly type charging and feeding device for an intelligent cemented soil mixing pile. The environment-friendly type charging and feeding device comprises a material collecting tank, a material conveying tank, an ash conveying header tube, an intelligent control system and a high-pressure gas supply system, wherein the material collecting tank and the material conveying tank are connected through a flexible connecting sleeve; the material conveying tank is provided with a weight measuring sensor for measuring weight of the material conveying tank; during drilling, quantitative cement ash is conveyed to a hole bottom by virtue of high-pressure air; during drill rod lifting, the high-pressure gas in the material conveying tank is input to a drill bit through the ash conveying header tube; high-pressure air can be injected to compensate when gas pressure in the material conveying tank is insufficient; waste gas which is exhausted into air is utilized to achieve environment-friendly effect; and meanwhile, by virtue of the action of the high-pressure air, a cement material and a soil body are mixed more uniformly, and resistance during lifting of a drill rod is reduced, so that energy-saving effect is achieved. By intelligently controlling ash charging and gas charging, the environment-friendly type charging and feeding device is simple in structural formula and convenient in mounting; dust-free construction can be realized, influence on a surrounding environment is avoided, civilized construction is realized and the cement material is saved; and cheating on workmanship and materials is avoided, so that the construction quality is completely guaranteed.
