The double-blocked rail without ballast construction technology promptly is a kind of novel railway job practices, and it is that railway roadbed is changed into cast-in-place board-like ballast bed structure.Sleeper is designed to symmetrical two pedestals and constitutes one by the reinforcing bar cast.Earlier in the ballast bed subgrade both sides a plurality of legs are set during construction, roadbed is carried out the horizontal level measurement and positioning, fluid concrete constitutes way of concrete foundations, and sleeper is embedded on the not solidified way of concrete foundations in groups.For guaranteeing accurate location and the horizontal accuracy of sleeper on roadbed, the crossbeam that connects on the leg of location can make the two accurate location, guarantees that thus sleeper is accurately positioned in the desired location of roadbed and guarantees desired level.By mode of vibration sleeper is combined with way of concrete foundations.Just must have thus a unit be working programme will be in groups sleeper be placed on the way of concrete foundations, and guarantee that the precision of sleeper laying, fixed mount promptly are to guarantee the pinpoint critical component of sleeper.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of double-blocked rail without ballast construction fixed mount.Both guarantee the accurate location of sleeper, can lay plurality of sleepers simultaneously again, satisfied required precision and the requirement of construction continuously that railway is laid.
The technical scheme that the utility model implementation above-mentioned purpose is taked is: it constitutes frame construction by two longitudinal beams and two transverse beams, wherein an end of a transverse beam is positioned at the outside of a longitudinal beam, one end of another root transverse beam is positioned at the outside of another root longitudinal beam, be provided with short column at the two ends of every transverse beam and make short column be positioned at the outside of transverse beam, thereby four short columns are symmetrical arranged with respect to frame center; Wherein the short column at longitudinal beam two ends is provided with the plain block that play supporting role, and is provided with the vee-block that plays the role of positioning on the short column at another root longitudinal beam two ends; Be provided with the supporting leg that many groups are used for fixing, locate sleeper in the bottom of every longitudinal beam, all be connected with sole in the lower end of supporting leg.
The utility model is to guarantee one of vitals of sleeper laying precision in the double-blocked rail without ballast construction, and its structure design is simple, and is easy to use flexible.It is the fastening devices of sleeper, can guarantee the accurate location of sleeper again.Setting up continuously and replacing to move and to guarantee carrying out continuously of sleeper laying operation by a plurality of fixed mounts simultaneously.
