Angle-strengthening span-reducing beam type roadway anchor rod and anchor cable supporting method

Номер: CN116136178A
Принадлежит:

The invention discloses a strong-angle span-reducing beam type roadway anchor rod and anchor cable supporting method. A top anchor cable, a vertex angle anchor cable and a top anchor rod which are arranged near a span-reducing point of a roadway top plate, and side anchor cables, side angle anchor cables and side anchor rods which are arranged near span-reducing points of two sides of a roadway are included. The anchor cables and the anchor rods are arranged in the same row, the vertex angle anchor cables are inclined towards the two sides of the roadway, and the inclination angle is 0-30 degrees; the side angle anchor cables incline towards the top and bottom plates of the roadway, and the inclination angle ranges from 0 degree to 30 degrees. According to the strong-angle span-reducing beam type roadway anchor rod and anchor cable supporting method, the anchor cable is regarded as a movable hinged support for supporting the rock beams by utilizing high strength and high rigidity of the ...

Curve pipe joint of rectangular jacking pipe, manufacturing method of curve pipe joint and curve pipe joint assembly

Номер: CN116163744A
Принадлежит:

The invention relates to a rectangular pipe-jacking curve pipe joint, a manufacturing method thereof and a curve pipe joint assembly, which are used for curve pipe-jacking engineering. The rectangular pipe-jacking curve pipe joint is provided with a plane top plate, a bottom plate and a curved side wall, and comprises a concrete frame which is a concrete curve pipe joint outer frame; the built-in steel member is arranged in the concrete frame and comprises a conventional reinforcement cage arranged in the plane top plate and the plane bottom plate and a profile steel row arranged in the curved side wall; the profile steel row is formed by n profile steel sections (n is greater than or equal to 2) with an included angle theta (theta lt; the angle theta is an included angle theta, and the included angle theta is a welding angle. The problems that in the prior art, due to the fact that a curve is replaced with a broken line, the pipe joint is dislocated, the contact area of the ends is reduced ...
