Problems solved by technology

[0002] Building water canals in mountainous or hilly areas and diverting water uphill can realize the desire to turn barren slopes into fertile fields and barren hills into mountains of flowers and fruits. However, due to the complex terrain of these areas, it is inevitable to build high bridges and build aqueducts frequently in order to build water canals according to conventional methods. Tunneling, these difficult and complicated projects will inevitably consume a lot of money and manpower. At the same time, according to the limited drop between the upper and lower water heads, it is required that the long canal can form a uniform slope, which increases the difficulty of construction. For these reasons, Many water diversion projects eventually had to be abandoned or abandoned halfway

Embodiment Construction

[0015] When selecting the route, it is not necessary to consider erecting bridges to repair aqueducts and tunneling, so that the canals undulate and meander with the changes of the terrain. During the survey, all the raised points of the entire route must be cleaned and arranged to ensure that all raised points When the starting point is lower than the starting water head, the overall direction of the canal must have a gradual transition from high to low. Some open transitional sections will be built along the canal according to the water distribution needs, and the rest will be closed and open transitional canals. The selection point of the section must be set at the intersection of the upper and lower drain connecting oblique line and the actual route of the canal. The skeleton of the closed canal is composed of spiral steel core plastic strip, distance control rope, polypropylene woven cloth and steel wire mesh. The outer plastic of the steel core plastic strip is made of polye...

Abstract

The invention provides quickly succeed mountain close canal. Its most difficulty is that it needs to build high bridge, aqueduct, and tunnel according to complex geographic environment. This will cause high investment and long construction period The invention uses spiral coil formed by steel core plastic strip as framework, and combines distance controlling rope, polypropylene fabric braided and steel wire mesh to pour into slush. It can be undulated along with the topography changing. Thus this can leave out more than 80 percents engineering investment and shorten construction period.

Description

1. Technical Field [0001] The invention relates to a canal construction technology, in particular to a construction technology of a fast closed canal suitable for mountainous and hilly areas. 2. Background technology [0002] Building canals in mountainous or hilly areas to divert the water from the mountains can realize the wish of turning barren slopes into good fields and barren hills into flower and fruit mountains. However, due to the complex terrain of these areas, it is inevitable to frequently erect bridges and build aqueducts and aqueducts by conventional methods. Tunneling, these difficult and complex projects will inevitably consume a lot of funds and manpower. At the same time, due to the limited drop between the upper and lower water heads, the long canals are required to form a uniform slope, which increases the difficulty of construction. For these reasons, Many water diversion projects eventually had to be abandoned or abandoned halfway. 3. Summary of the inventi...
