Embodiment

[0025] Embodiment: A kind of small cross-section canal lining fast construction method, comprises the following steps:

[0026] (1) Measurement stakeout:

[0027] Carry out measurement and stakeout according to the plane position of the drainage ditch provided by the design drawings, use a total station or theodolite to define the central positioning pile and the bottom slope junction pile, and place the central pile at every 50m interval (nail piles at intervals of 5m at the bend) and number them , use a level to measure the height of the pile point, and then determine the sideline of the drainage ditch according to the center line, and mark it with a lime line;

[0028] (2) Channel filling

[0029] The channel is filled with the excavated earthwork in the nearest grid, paved and filled according to the horizontal layer, the layer thickness and compaction parameters are determined according to the field test; the filled soil material is mainly transported by loader and backh...

Abstract

The invention belongs to the technical field of infrastructure engineering, and relates to a small-section canal lining rapid construction method. The method comprises the following steps of surveyingand setting out, canal filling, canal excavation, cushion layer construction, canal lining, finishing maintenance and the like. The method accelerates the construction progress, improves the construction quality, reduces the construction cost, improves the construction progress and quality, and reduces the construction cost, a plurality of procedures of form installation, manual leveling, vibrating and surface finishing are completed at a time through equipment, meanwhile, continuous construction is achieved, in consideration of material use, form use is omitted, wood is saved, waste of concrete is avoided through continuous construction, the size consistency of construction sections is guaranteed, and the problems of vibration missing and the like are avoided during continuous concrete vibration.

Description

technical field [0001] The invention belongs to the technical field of infrastructure engineering and relates to a rapid construction method for small-section canal lining. Background technique [0002] At present, there are mainly two methods for channel concrete lining construction: manual lining and lining machine construction. Artificial lining includes foundation surface treatment, formwork installation, concrete construction and formwork removal process, and warehouse adjustment construction is required. Manual lining requires a lot of manpower and consumes a lot of formwork, and waste is generated during the construction of the last warehouse on the shift. Construction quality is difficult to guarantee. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a rapid construction method for channel lining with a small cross-section. [0004] In order to achieve the above object, the present invention adopts the fo...
