Embodiment Construction

[0037] Such as figure 1 , figure 2 As shown, a frame-type track foundation includes a track foundation, and the ends of adjacent Type III concrete sleepers 2 in the track foundation are connected by an inter-sleeper coupling mechanism to form a frame-type overall track foundation.

[0038] The inter-pillow connection mechanism includes a left pillow connection seat 1a, a right pillow connection seat 1b and a splint 3;

[0039] see Figure 3-Figure 8 , the left clamping pillow connecting seat 1a and the right clamping pillow connecting seat 1b are fully symmetrical structures, including a base 11, a vertical plate I12, a vertical plate II13, an inclined plate 14 and a reinforcing connecting plate 15; the vertical plate I12 and the vertical plate The plates II13 are perpendicular to each other in an "L" shape and are vertically arranged on the bottom plate 11. The vertical plate I12 is provided with an oval elongated hole 121, which is used for the splint 3 to be fixed in the...

Abstract

The invention relates to a novel frame-type rail foundation which comprises a rail foundation body. The end parts of adjacent III-shaped concrete sleepers in the rail foundation body are connected through inter-sleeper linking mechanism to form the frame-type overall rail foundation. On the basis that the rail foundation, namely a line foundation, is not changed, the line foundation remains the original line foundation unchanged, a special overload and unbalanced load sleeper does not need to be replaced, the original distance between sleepers does not need to be adjusted, all that is needed is to adopt the inter-sleeper linking mechanism to connect the original sleepers into an overall frame structure, the whole fixation and balance are realized, sufficient stability is provided, the detection precision is ensured, and the construction workload is greatly reduced.

Description

technical field [0001] The invention relates to a novel frame track foundation. Background technique [0002] At present, in order to weigh and detect the loading capacity and loading quality of railway freight cars in operation in China, it is necessary to install a dynamic rail scale or a dynamic over-eccentric load detection device. In order to ensure the detection accuracy, high requirements are put forward for the stability and rigidity of the track foundation of the installation equipment section. The previous practice was to use integral concrete foundations or custom-made special sleepers to connect them into an integral foundation to meet the requirements. The integral concrete foundation is to excavate the foundation pit on the ballast bed, arrange steel bars, pour concrete, and take shape after maintenance. The special sleeper method is to customize special sleepers in advance, and pre-embed steel structural parts for connection in the sleepers. Transport the s...
