The invention discloses a frame type rail weighing sensor. The frame type rail weighing sensor comprises a support, strain beams and a bearing beam, wherein the support comprises a support main body;side supports are symmetrically arranged on two sides of the support main body; the strain beams are arranged at two ends of the side supports respectively; a strain hole is formed in the side face ofeach strain beam; a mounting hole is formed in each side support; a rail gauge adjusting device is arranged on the outer side of each side support; each bearing beam is positioned at the outer end ofthe corresponding strain beam; the outer ends of the strain beams are connected through the bearing beams respectively; and steel rail baffle plates are arranged at two ends of the upper plane of each bearing beam. According to the frame type rail weighing sensor, the space between the steel rails and prestressed concrete sleepers is utilized efficiently and effectively, a special sleeper does not need to be used, the equipment cost is reduced, the rail gauge adjusting devices are installed on two sides of the side supports of the sensor for carrying out the adjustment of rail gauges, and lateral force received by the steel rails and the frame type rail weighing sensor is born by shoulders of sleeper rail bearing grooves, so that the strained condition of the sleepers is closer to that ofgeneral sleepers.

The invention relates to the technical field of tubular pile end plates and discloses a tubular pile end plate applicable to a prestressed concrete tubular pile foundation. The tubular pile end platecomprises a tubular pile end plate body; anchor holes, countersunk holes, positioning holes, a first groove and a second groove are formed in the front face of the tubular pile end plate body; the front face of the tubular pile end plate body is provided with a connecting ring, and the inner wall of the connecting ring is provided with a reinforcing layer. According to the tubular pile end plate applicable to the prestressed concrete tubular pile foundation, through arrangement of the first groove and the second groove, the first groove and the second groove are adopted for reducing the material consumption of the tubular pile end plate; moreover, the outer edge of the tubular pile end plate body is designed according to a certain gradient so that the material consumption of the tubular pile end plate can be reduced to a certain extent, and thus the use cost of the tubular pile end plate is reduced.
