Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with specific embodiments.

[0020] A ballastless track self-compacting concrete pouring peel-off inspection method, the test site conditions and construction methods of the peel-off inspection method are basically consistent with the construction site; wherein the ballastless track includes steel rails, track slabs, self-compacting concrete filling layers, Intermediate isolation layer, reinforced concrete base or support layer, including the following steps:

[0021] Step 1. After the pouring of the self-compacting concrete is completed and the initial setting is completed, a tool is used to separate the track slab from the self-compacting concrete layer. Specifically, the bottom of the track slab can be lifted lightly with a fine-tuning jack on the track slab, or the track can be lifted lightly with hoisting equipment to separate the track slab from the self-compacting concrete layer.

Abstract

A plate removal detection method for detecting self-compacting concrete pouring of a ballastless track comprises steps as follows: firstly, a track plate is separated from a self-compacting concrete layer through a tool after pouring and initial setting of self-compacting concrete; next, the track plate is hoisted by hoisting equipment in 24 hours and then slowly put on a plate storage pedestal of a testing bench; finally, the self-compacting concrete layer is checked carefully after the track plate is hoisted away, whether bleeding, unsaturated pouring, bubbling, layering and cracking phenomena occur to the self-compacting concrete layer is checked, recorded and analyzed, and the plate-removal detection of self-compacting concrete pouring is finished. The pouring quality of the self-compacting concrete is detected visually and directly, the hardening result of the self-compacting concrete can be reflected comprehensively, the construction technology is learnt about well and improved, and the construction quality is improved.

Description

technical field [0001] The invention relates to an inspection method, in particular to a method for inspecting ballastless track self-compacting concrete pouring and removing slabs, and belongs to the technical field of railway ballastless track slab installation. Background technique [0002] CRTSⅢ type slab ballastless track is a ballastless track structure independently developed by my country and has completely independent intellectual property rights. , reinforced concrete base or supporting layer and other parts. The quality of the self-compacting concrete filling layer is related to the overall performance of the CRTSⅢ slab ballastless track, so the filling of self-compacting concrete is very critical. [0003] At present, the quality of self-compacting concrete pouring is usually tested by sampling inspection or specimen inspection. Sampling inspection is to drill a certain specification of concrete on the poured self-compacting concrete as a sample to test the perfo...
