Problems solved by technology

Stone masonry anti-seepage can be used locally in the canal along the mountain and in areas rich in stone materials, with high impact flow velocity and strong frost resistance, but it is not suitable for mechanized construction, the construction quality is difficult to control, the masonry workload is large, and many materials are used. Higher requirements for masonry technology
The cost of brick anti-seepage is low, the material is convenient, the construction technology is simple, and the anti-seepage effect is better, but the frost resistance is poor, so it is not suitable for use in northern areas.
Asphalt material anti-seepage has the advantages of anti-seepage, durabi...

Embodiment 1

[0033] Embodiment 1: dry and hard solidified soil channel construction:

[0034] see figure 1 , image 3 (a), specifically including the following steps:

[0035] 1) Level the construction site, remove turf, tree roots, etc. According to the requirements of the design drawings, carry out on-site measurement and stakeout, the width of the canal bottom is 1.0m, the width of the top of the canal is 6.0m, and the depth of the canal is 1.5m, and the axis of the canal is determined. At a distance of 10m from one side of the canal, set a benchmark every 50m to ensure that the elevations of the canal bottom and top of each section meet the design requirements.

[0036] 2) Excavate the canal foundation with an excavator, level it out, fill it up manually and compact it with a rammer. The error of the channel base groove surface after compaction shall not exceed 30mm.

[0037] 3) Grinding the excavated soil material to make the particle size less than 10 mm, and then mixing with wa...

Embodiment 2

[0043] Embodiment 2: construction of plastic solidified soil channel:

[0044] see figure 2 , image 3 (b), specifically including the following steps:

[0045] 1) Level the construction site, remove turf, tree roots, etc. According to the requirements of the design drawings, carry out on-site measurement and stakeout, the width of the canal bottom is 1.0m, the width of the top of the canal is 6.0m, and the depth of the canal is 1.5m, and the axis of the canal is determined. At a distance of 10m from one side of the canal, set a benchmark every 50m to ensure that the elevations of the canal bottom and top of each section meet the design requirements.

[0046] 2) Excavate the canal foundation with an excavator, level it out, fill it up manually and compact it with a rammer. The error of the channel base groove surface after compaction shall not exceed 30mm.

[0047] 3) Take a certain volume of excavated soil and pass it through a 10mm soil sieve. According to the ratio o...

Abstract

The invention discloses a construction method of building anti-permeability channels using soil curing agent. The method comprises the following steps: blending soil, a soil curing agent, water and fiber to form a curing soil mixing material; and dividing the curing soil mixing material into dry and solid curing soil and plastic curing soil by the water content of the curing soil mixing material, compacting the dry and solid curing soil with tamp equipment to form an intensive strengthened soil anti-permeability layer, and as for the plastic curing soil, adopting cement mortar spray gun technology to muddy spray curing soil to channel base to form a strengthened soil anti-permeability layer, further laying cement mortar on the surface of the strengthened soil anti-permeability layer to form a protection layer, so that frost heaving and destruction of anti-permeability channels in northern cold area can be effectively avoided. The method can solve the problem in the prior construction method of building anti-permeability channels using soil curing agent, increase construction speed of building anti-permeability channels using the soil curing agent, reduce the construction cost, and prolong the service life of the channels. The invention is of great significance for the development of water-saving irrigation and establishment of conservation-oriented society.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and relates to materials, construction techniques and structural treatment for building anti-seepage canals, in particular to a method for building anti-seepage canals using soil curing agents, which is applicable to main canals, branch canals, bucket canals and agricultural canals, etc. Various anti-seepage channel projects. Background technique [0002] At present, the anti-seepage length of main and branch canals in my country is 551,100 km, accounting for only 18% of the total length of canals in the country, and more than 80% of the canals have not taken anti-seepage measures, resulting in the average value of canal water utilization coefficient is less than 0.5, more than 50% of irrigation water is lost in the process of channel water delivery, and the amount of water lost by irrigation channels is as high as 170 billion m per year 3 , the waste of irrigation water is ...
