Detailed Description
The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings for the understanding of those skilled in the art:
as shown in fig. 1-2, reference numerals 1-9 in the figures denote: the device comprises a prefabricated track slab 1, a track bearing platform 2, a pouring hole 3, an exhaust hole 4, a settlement observation mark 5, a mileage sign 6, a mark head 7, a mark rod 8 and a ring groove 9.
The embodiment is as follows: as shown in fig. 1 and 2, the prefabricated track slab body embedded with the settlement observation point and the mileage sign in the embodiment is a prefabricated track slab 1, and the prefabricated track slab 1 is laid below the steel rail to support the steel rail so as to form track traffic. As shown in fig. 1, two rows of rail bearing platforms are arranged on two sides of a plate body of a prefabricated track plate 1, the two rows of rail bearing platforms 2 are respectively identical to the line direction of two steel rails, each row of rail bearing platform comprises a plurality of rail bearing platforms 2, and the steel rails can be installed and fixed through installing a fastener system and the like on the rail bearing platforms 2.
As shown in fig. 1, prefabricated track board 1 has been seted up one along the central line of line direction and has been pour hole 3 and two exhaust holes 4, these two exhaust holes 4 are arranged in the both sides of pouring hole 3, wherein pour hole 3 and be used for pouring self-compaction concrete to prefabricated track board 1's plate body below, form self-compaction concrete cushion between prefabricated track board 1's below and ballast bed basis, two exhaust holes 4 then exhaust when pouring self-compaction concrete respectively, guarantee the pouring compactness of self-compaction concrete.
As shown in fig. 1, two settlement observation marks 5 are pre-buried on a prefabricated track slab 1, both the two settlement observation marks 5 can be used as settlement observation points for settlement observation operation, and settlement observation equipment is used to observe the settlement observation marks 5 as the settlement observation points, so that the settlement condition of the prefabricated track slab 1 can be known; by embedding two settlement observation marks 5 in a single prefabricated track plate 1, the settlement degree and the settlement direction of the prefabricated track plate 1 can be effectively evaluated, for example, the settlement amount measured at one settlement observation mark A is larger than that measured at the other settlement observation mark B, namely, the settlement can be reflected to be uneven settlement from the A to the B.
The two settlement observation marks 5 are symmetrically arranged on the center line of the prefabricated track slab 1 along the line direction, and the two settlement observation marks 5 are respectively arranged on two sides of the two exhaust holes 4; on one hand, the settlement observation marks 5 are symmetrically arranged at the center line position of the prefabricated track plate 1 along the line direction, so that the settlement observation result can effectively reflect the current condition of the prefabricated track plate 1, and meanwhile, the settlement change condition and the mutual influence between the prefabricated track plate and the adjacent prefabricated track plate can be conveniently evaluated; on the other hand, the settlement observation mark 5 is arranged on the outer side of the exhaust hole 4, so that the adverse effect of the hydration heat of the self-compacting concrete on the structure of the settlement observation mark 5 can be reduced as much as possible, and the arrangement position of the settlement observation mark 5 is changed and even the structure is damaged.
As shown in fig. 2, the sedimentation observation marker 5 in this embodiment is composed of two parts, namely a marker head 7 and a marker rod 8, wherein the marker head 7 is arranged on the top of the marker rod 8, and the two parts are integrally formed to ensure the structural strength.
