Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: the above-mentioned method adopts the method of paving concrete once and vibrating with a vibrator once to form the channel lining. Since the thickness of the common channel lining is about 10 cm, the thickness is still relatively thick. There will be situations where some parts of the canal lining cannot be vibrated firmly, so the local structure of the canal lining is not compact enough, which affects the quality and aesthetics of the entire canal project

Embodiment 1

[0056] refer to figure 1 and figure 2 , is a kind of channel lining concrete cast-in-place method disclosed by the present invention, comprising the following steps: configuring concrete S1, formwork installation S2, concrete warehouse surface wetting S3, first paving concrete S4, first vibrating S5, second Second paving concrete S6, second vibrating S7, scraping treatment S8, polishing treatment S9, surface finishing and calendering S10, and curing treatment S11.

[0057] Concrete configuration S1: The raw materials of the following mass parts of concrete are prepared: 50-60 parts of water, 90-110 parts of cement, 390-400 parts of sand, 360-380 parts of pebbles, 2-4 parts of admixture, the slump of concrete Between 100-150 mm, the water-binder ratio of concrete is between 0.50-0.60, and the sand ratio of concrete is 50.0%-53.0%. The concrete of the above formula has high structural strength after curing, is not easy to seepage, and has a long service life, thereby prolongi...

Embodiment 2

[0075] refer to figure 2 and image 3 , is a non-linear canal lining construction method disclosed in the present invention, the canal includes a linear area and a curved area, the canal lining 3 includes: a slope surface lining 31 and a bottom surface lining 32, and the channel lining 3 in a linear area adopts The block-by-block method of construction is adopted, and the channel lining 3 in the curved area is constructed by the method of pouring through the warehouse.

[0076] Based on the channel lining concrete casting method as described in Embodiment 1, the non-linear channel lining construction method includes: canal foundation treatment S101: remove the bad soil and garbage on the surface of the canal foundation 1, and the pits on the surface of the canal foundation 1 Fill and compact with backfill soil, the compaction degree of the backfill soil is not less than 0.92; laying the lining cushion S102: Lay the sandstone cushion 2 on the bottom surface of the canal found...

Abstract

The invention relates to an in-situ pouring method for channel lining concrete and a non-linear channel lining construction method, comprising the following steps: configuring concrete, installing formwork, wetting the surface of the concrete bin, paving concrete for the first time, vibrating for the first time, and Second paving concrete, second vibrating, screeding treatment, grinding treatment, finishing calendering and curing treatment. The invention has the effects of paving concrete twice and vibrating twice, so that the canal lining structure obtained by construction is more dense, and the quality and aesthetics of the whole canal project are improved.

Description

technical field [0001] The invention relates to the technical field of channel construction, in particular to a channel lining concrete casting method and a non-linear channel lining construction method. Background technique [0002] Water conservancy projects are basic projects related to the national economy and people's livelihood, and the construction of water conservancy channels is an important part of water conservancy projects. Only by ensuring that the construction methods of water conservancy channels are appropriate can the quality of water conservancy projects be ensured. [0003] A Chinese invention patent with the publication number CN109295928A has now been retrieved, which discloses a water conservancy channel construction method, comprising the following steps: (1) first adopting an excavator to rough slope, and then loosening the soil on the slope; (2) The rust spots, calcium film, broken and loose rock blocks on the slope shall be removed and treated; (3) ...
