The invention relates to an angle hoop tie reinforcement system of a traditional stone masonry house and a construction technology. The system comprises long steel angles, the long steel angles are used for fixedly clamping outer wall corner angles of the stone masonry house, and one side of each short steel angle is connected with the corresponding long steel angle through diagonal tension plates. A connecting hole is formed in the middle of the other side of each short steel angle. Every two adjacent short steel angles are connected through tie bars penetrating through the connecting holes. The long steel angles, the short steel angles, the diagonal tension plates and the tie bars are mutually connected to form closed steel hoop structures. The steel hoop structures are hooped around the outer wall of the stone masonry house. The tie bars are prestressed steel bars. The steel angles are fixed to the corners of the wall of the stone masonry house, every two adjacent steel angles are connected through the steel tie bars, and prestress is exerted on the steel tie bars, so that the steel tie bars are matched with the steel angles to form the steel hoop structures. The steel hoops generate large constraint force on the corners of the wall, so that the stress condition of the original structure of the stone masonry house is changed, shear stress of connecting positions of longitudinal and transverse walls is reduced, and cracks at the connecting positions of the longitudinal and transverse walls and further expansion of cracks already generated are avoided.

The invention discloses a prestressed construction process for building a high-rise building structure. All steel wire ropes in prestressed tendons are dispersedly anchored through first anchor bearing plates and corresponding first anchorage devices, so that the problem that stress on the surrounding structure of the first anchor bearing plates is concentrated after tension releasing is avoided; all the first anchor bearing plates are arranged along the spherical surface, i.e. the bearing surfaces of all the first anchor bearing plates are supported by an imaginary sphere, so that the stress is more uniform, and the stability of the anchoring structure is facilitated; and second anchor bearing plates, cavity molds and templates are relatively fixed, so that holes, through which the prestressed tendons can penetrate, of the second anchor bearing plates, the cavity molds and the templates are not staggered, the prestressed tendons can be arranged to be perpendicular to the outer surfaces of the templates all the time, the process requirement is met, and accurate implementation of prestress of the high-rise building structure is guaranteed. The prestressed construction process has the advantages of simple steps, convenience in operation and good effect.

The invention discloses a building roof construction process. A construction roof comprises a roof structure plate, a parapet wall and a roof surface layer, wherein the parapet wall is arranged above the roof structure plate, the roof surface layer is paved on the roof structure plate, a roof exhaust system is arranged on the construction roof and comprises a plurality of first horizontal exhaust pipes, the first horizontal exhaust pipes are respectively laid in a slope finding layer or a heat insulation layer in the roof surface layer, two ends of each first horizontal exhaust pipe are respectively connected with a vertical exhaust pipe, and the vertical exhaust pipes are embedded in the side walls of the parapet wall and a discharge flue or the side wall of an exhaust passage. The construction process of a construction roof comprises the steps of 1, surveying and setting out; 2, parapet wall, discharge flue and exhaust passage construction; 3, horizontal exhaust pipe positioning installation; 4, exhaust pipe connection; 5, roof surface layer construction; and 6, rigid protecting layer mesh division and caulking construction. The construction process has the advantages that the steps are simple, the operability is high, the realization is convenient, in addition, the work efficiency is high, the construction effect is good, and the construction quality of the construction forming building roof can be effectively ensured.

The invention provides a global position system (GPS) monitoring pier for frozen soil areas and swelling soil areas. The GPS monitoring pier comprises a pier foundation, a heat-preservation and water-resisting layer, a pier column and a GPS base for installing a static GPS. The pier foundation is buried under the surface of the earth, the pier column is vertically installed in the pier foundation, and the upper end of the pier column protrudes out of the surface of the earth; the heat-preservation and water-resisting layer is horizontally installed on the pier column, and the GPS base is installed at the top end of the pier column. The pier foundation is formed by pouring concrete. The pier column is a concrete molding plastic pipe filled with reinforced concrete internally. The invention further provides a construction process of the GPS monitoring pier. According to the GPS monitoring pier for the frozen soil areas and the swelling soil areas and the construction process thereof, the manufacturing process of a traditional GPS monitoring pier is simplified through the plastic pipe; the stability of the monitoring pier is ensured through burial depth, and the situation that freezing and thawing cycles and drying and watering cycles influence the monitoring pier is avoided; the pier foundation keeps in an environment of constant dry, wet and temperature by arranging the heat-preservation and water-resisting layer, and the influences of landforms and vegetation on the monitoring pier are decreased; the monitor precision and stability of the monitoring pier are high, and the device durability is good.
