The basic rail 1 and the guard rail 3 are fixedly connected to the basic rail base bottom plate 2 by welding. A basic rail base slide plate 4 is arranged between the basic rail 1 and the guard rail 3. The basic rail base slide plate 4 is fixedly connected with the corresponding basic rail 1 and the guard rail 3 to form a structure with an open upper part and a closed lower part to form a cavity. The structure is not only high in strength and good in stability, but also has good sealing performance, ensuring its durability in use. A point rail 5 is arranged on the basic rail base slide plate 4. Since the turnout is open at the top, it is convenient to maintain and replace the point rail. The basic rail 1 of this embodiment adopts 60R2 steel rail, the material of the basic rail base bottom plate 2 is Q235, and the thickness is 90-95mm. The material of the guard rail 3 and the basic rail base slide plate 4 adopts NM400, and the guard rail is made of steel with a thickness of 40mm. The turnout of this embodiment is relatively light in weight compared with the integral turnout of the prior art, and is convenient for hoisting, transportation and laying.
