Problems solved by technology

Although in recent years, sleepers have gradually formed factory prefabricated production, which is more suitable for projects with large demand, but for projects with small scale and high requirements on appearance, on-site prefabrication is also a good choice

Embodiment Construction

[0016] The technical solutions of the present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0017] A non-factory sleeper prefabrication construction method, comprising the steps of:

[0018] (1) Formwork design and processing: select all-steel formwork, design and process 33 sets of side forms and 99 sets of bottom forms;

[0019] (2) Process treatment of the template surface: apply a release agent on the template surface, and control the thickness of the coating film at 0.05-0.2kg / m 2 , the application time is controlled within 24 hours before the mold is erected, and the application is completed and covered with a plastic film;

[0020] (3) Formwork installation: During the production process of the formwork, the upper part of the sleeper is made into a bottom formwork, and pre-embedded bolts are reserved on the bottom formwork, and the construction is reversed, with the top big and the bottom small; ...

Abstract

The invention relates to a non-industrialized sleeper-prefabricating construction method. The non-industrialized sleeper-prefabricating construction method comprises the following steps of 1 formwork design and processing, 2 formwork surface treatment, 3 formwork installation, 4 steel bar machining and installation, 5 concrete raw material detection, 6 concrete mixing ratio design, 7 concrete casting and 8 formwork removal and maintenance. The non-industrialized sleeper-prefabricating construction method is a complete, scientific and reasonable sleeper formwork and clear-water concrete engineering construction process, provides effective guidance for small sleeper-prefabricating engineering construction, the problem that a small member formwork is complicated, the air bubble amount on the concrete surface is large, a formwork is inconvenient to cycle and the like is solved, and the quality, safety and constriction period of prefabricated sleepers are ensured.

Description

technical field [0001] The invention relates to the technical field, in particular to a non-factory sleeper prefabrication construction method. Background technique [0002] At present, most of the sleepers used in my country's projects are prefabricated in factories, and there are prefabricated sleeper structures under the track of the stacker-reclaimer in the Rizhao Ore Wharf yard, with a total of more than 3,000 pieces, which are limited by quantity and cost. Although in recent years, sleepers have gradually formed factory prefabricated production, which is more suitable for projects with large demand, but for projects with small scale and high requirements on appearance, on-site prefabrication is also a good choice. In the process of non-factory prefabrication, attention should be paid to the design and construction of formwork and fair-faced concrete. Contents of the invention [0003] The purpose of the present invention is to provide a non-factory sleeper prefabric...
