The application relates to a rock-embedded steel pipe pile construction guiding device which comprises a base, an external guiding cylinder frame, two internal guiding arc plate frames, two connecting rods, two extension arc plate frames, two transverse driving assemblies and two longitudinal driving assemblies. The transverse driving assemblies are connected to the two sides of the external guiding cylinder frame, the transverse driving assemblies are connected to the internal guiding arc plate frames, the internal guiding arc plate frames are internally provided with mounting cavities, the internal guiding arc plate frames are internally provided with the connecting rods, the bottom ends of the connecting rods are connected to the extension arc plate frames, the internal guiding arc plate frames are connected to the longitudinal driving assemblies, the longitudinal driving assemblies are connected to the connecting rods, and each internal guiding arc plate frame is connected to the external guiding cylinder frame through a connecting assembly. The technical problem that the construction mode in the prior art cannot accurately guarantee the design pile top position, causes resource waste and cost increase, and needs to use measuring instruments is solved.

The utility model discloses an anti-interference satellite navigation antenna test device, which comprises a base, a first side plate, a second side plate, a third side plate, a fourth side plate, a fifth side plate and a sixth side plate, wherein the base is square, and the edge of the base is provided with a plurality of clamping hole sites, so that the base can be conveniently mounted on a test platform; a hexagonal hole is formed in the base, a plurality of screw holes are formed in the edge of the hexagonal hole, the side plates are fixedly arranged on the base according to preset positions, and the inner bottom edges of the side plates coincide with the edge of the hexagonal hole. The top surfaces of the first side plate, the second side plate, the third side plate, the fourth side plate, the fifth side plate and the sixth side plate are provided with a plurality of fasteners so as to fix a to-be-tested product. According to the device, a clamping hole site is additionally arranged on the base, installation of various testing platforms is greatly facilitated, the base is of a square structure, and the direction can be well positioned in the machining process; and a modularized splicing structure is adopted as a whole, so that the cost and the processing time are greatly saved.
