Abstract

The invention discloses a construction method of an urban hydrophilic ecological river channel. By using mixing piles, the functional requirements of a river bank retaining wall can be met, the earthexcavation, filling, abandonment and transport of the retaining wall are reduced, the engineering construction efficiency is improved, the construction period is shortened by about one half compared with that of a cast-in-place pile structure, and the construction method is more economical than that of the cast-in-place pile structure. As soil is reinforced in situ, compared with a grouted rubblegravity or reinforced concrete L-shaped retaining wall cantilever-type structure needing bulk excavation and supporting for base expansion, the in-situ retaining wall structure does not need earth andmud discharge, causes low noise and little environmental pollution, does not disturb adjacent soil during construction, has low supporting requirements and will not cause ground sinking, house tilting and road cracking. The construction method is used in the technical field of remediation of the hydrophilic ecological river channel.

Description

technical field [0001] The invention relates to the technical field of hydrophilic ecological river course improvement, in particular to a construction method for urban hydrophilic ecological river courses. Background technique [0002] At present, with the rapid development of cities and the increasing shortage of urban construction land, a large number of river embankments in central urban areas (ie urban river sections) mostly use vertical embankments (or hardened and reinforced embankment foot retaining walls) to defend against flood threats. Although the vertical embankment provides a wide and flat embankment platform as a belt-shaped space for civic activities, the river bank is a vertical surface of concrete or masonry, which makes it difficult for vegetation to grow, and the ecological landscape effect is poor, and it is not conducive to the rescue of people who fell into the water. With the increasing requirements for the construction of ecological civilization, the...
