Description

Support for installing multi-model waveguide tubes

Technical Field

The utility model relates to a waveguide installation technical field especially relates to a support for installing polytypic waveguide.

Background

The ballast bed is an important component of the track and is the foundation of the track frame. The ballast bed is generally referred to as a layer of ballast (ballast) laid on the underlying surface of the railroad ties. The sleeper supporting device has the main functions of supporting the sleeper, uniformly transmitting the huge pressure on the upper part of the sleeper to a roadbed, fixing the position of the sleeper, preventing the sleeper from longitudinally moving or transversely moving, greatly reducing the deformation of the roadbed, simultaneously relieving the impact of locomotive wheels on steel rails and facilitating drainage. The ballast bed is laid on a roadbed, a bridge or a tunnel and other infrastructure, and a gravel layer or a concrete layer below the steel rail, the sleeper or the bearing block. The ballast is small block-shaped granite with the diameter of 20-70 mm, and gaps and friction force exist between blocks, so that the track has certain elasticity. The elasticity can not only absorb the impact and vibration of the rolling stock, make the train run more stably, but also greatly improve the working conditions of the rolling stock, the steel rail, the sleeper and other components and prolong the service life. Once the elasticity of the ballast is lost, the load borne by the reinforced concrete sleeper is increased by 50-80% compared with the normal state.

The ballast bed is divided into a common ballast bed, an asphalt ballast bed and a concrete integral ballast bed. The ballast bed is usually built up from hard crushed stones of a certain particle size, grading and strength, and on secondary roads graded pebbles or grit may also be used. The asphalt ballast bed is a structural form in which emulsified asphalt or asphalt mortar is added in order to improve the dispersion characteristics of a general ballast bed. The whole ballast bed is usually of a cast-in-place reinforced concrete structure and is usually used in a tunnel or on a bridge which is not easy to deform. The ballast track using broken stones as the ballast bed is the basic form of the railway track in China at present. The ballast bed is based on the broken stones, has rich resources, low price and longer service life, and evenly transmits force by the structural advantages of particle shapes, thereby keeping the geometric precision of the spatial form and position of the track by better elasticity. Obviously, this structure of the ballast bed will also be used for a long time.
