Description

Technical Field

[0001] The utility model belongs to the technical field of railway construction, and specifically discloses a mobile cross-line concrete pouring tool. Background Art

[0002] The main features of CRTS III slab track are: the filling layer under the slab is made of self-compacting concrete, and the CA mortar commonly used in Type I and Type II slab track is eliminated.

[0003] The under-slab filling layer is located between the track slab and the base plate. It is an important structural component of the CRTSⅢ slab ballastless track. It plays a key role in connecting the upper and lower parts and transmitting the longitudinal, transverse and vertical loads from the upper track slab. The self-compacting concrete used as the under-slab filling layer material needs to be poured after the track slab is fine-tuned. Self-compacting concrete slurry retaining formwork is set around the under-slab filling layer to be poured. A hollow cavity structure is formed between the slurry retaining formwork, the base plate and the track slab. The under-slab filling layer is formed by pouring self-compacting concrete into the hollow cavity. Self-compacting concrete has the characteristics of no swelling, no shrinkage and no deformation during the solidification process, which ensures that the fine-tuned track slab will not be affected by the deformation of the underlying layer.

[0004] Self-compacting concrete has high fluidity, gap permeability and anti-segregation properties. It can be compacted and formed by its own weight without vibration during pouring. To ensure the performance of the self-compacting concrete layer after the slab is removed, such as: the self-compacting concrete is fully poured and tightly bonded to the base plate and track plate; the surface quality has no floating slurry and foam accumulation layer, and there are few process bubbles; the self-compacting concrete has good homogeneity and high density, and the aggregate is evenly distributed at the cut section; the side of the self-compacting concrete is smooth, dense, and has no pockmarks, etc., in addition to ensuring the performance of the self-compacting concrete material itself, there must also be a strict raw material ratio. In addition, the construction process and tooling are also an indispensable part of ensuring its strength quality and appearance quality.

[0005] The existing self-compacting concrete pouring equipment, such as a self-compacting concrete mixing and pouring device disclosed in CN208197201U, is a large-scale equipment with high requirements for working space. When the track passes through a tunnel, there are tunnel walls on both sides, and the working space is narrow, making it difficult for large equipment to enter for pouring. Utility Model Content
