Embodiment Construction

[0029] The technical solutions of the various embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work are within the protection scope of the present invention.

[0030] Considering that the central gutters of the double-line tunnels are currently poured on site, the construction speed is slow, and the edges of the central gutters are prone to damage after pouring, and the maintenance conditions are poor. This embodiment provides a single tunnel central gutter , and a preparation method thereof and a water ditch in the center of a tunnel.

[0031] A tunnel center ditch monomer, the two ends of which are connecting ends respectively, and a groove struc...

Abstract

The invention relates to the technical field of underground engineering, in particular to a tunnel central ditch, a single body thereof and a method for manufacturing the single body. Connecting ends are respectively arranged at two ends of the single body of the tunnel central ditch, openings are formed in the connecting ends, the single body of the tunnel central ditch is of a groove structure, and a concrete cover plate covers an upper opening of the groove structure; mixture of quartz sand, steel fibers, 425R ordinary silicate cement, micro-silicon powder, mineral waste material powder, water reducing agents and water are poured on the side walls and the bottom of the single body of the tunnel central ditch. A plurality of single bodies of the tunnel central ditch are serially connected with one another to form the tunnel central ditch, the distance between each two single bodies is shorter than 8 millimeters, and altitude difference is smaller than 5 millimeters. The method includes portioning materials; mixing the materials to obtain the mixtures; feeding the mixtures into molds and molding the mixtures in a vibration manner; carrying out primary curing on the mixtures; carrying out final curing on the mixtures to obtain the single body of the tunnel central ditch. The tunnel central ditch, the single body and the method have the advantages that the structure of the single body of the tunnel central ditch is preliminarily manufactured outside a hole and then is mounted in a tunnel, accordingly, the construction speed can be increased, and the construction quality can be improved.

Description

technical field [0001] The invention relates to the technical field of underground engineering, in particular to a tunnel center ditch monomer, a preparation method and a tunnel center ditch. Background technique [0002] At present, C30 cast-in-situ concrete is generally used in the central ditch of high-speed railway double-track tunnels. The construction speed is slow, and the construction and maintenance conditions in the tunnel are poor, making it difficult to guarantee the construction quality, and the edge of the ditch is prone to damage. Contents of the invention [0003] Embodiments of the present invention provide a tunnel center ditch monomer, a preparation method and a tunnel center ditch, which can solve the problems of slow construction speed and poor construction quality due to on-site pouring. [0004] According to one aspect of the present invention, there is provided a tunnel center ditch unit, the two ends of which are connecting ends respectively, and a...
