Embodiment

[0030] Embodiment: the construction process of above-mentioned concrete alveolar stilling basin is:

[0031] Excavate the construction grooves of floor structure concrete 1, alveolar structure concrete 2, and backfill concrete 3 at the front end of the bank slope respectively; bind the structure edge with steel bars at the edges of the construction grooves of floor structure concrete 1, alveolar structure concrete 2, and backfill concrete 3 ; The reinforcement mesh 10 is vertically arranged between the construction groove of the floor structure concrete 1 and the backfill concrete 3 and fixed; the structural concrete with a strength>C25 is poured into the construction groove of the floor structure concrete 1 and the alveolar structure concrete 2, and the backfill concrete 3 Backfill concrete with strength ≤ C15 is poured in the construction tank, the two kinds of concrete are poured at the same time and the pouring rate is equal to ensure that the liquid level of the two kinds ...

Abstract

The invention discloses a concrete tooth groove stilling pool and a construction method thereof. The stilling pool comprises base plate structure concrete, wherein the base plate structure concrete is arranged at a front end of a bank slope; tooth groove structure concrete is arranged at an upstream of the base plate structure concrete; backfill concrete is arranged at a downstream of the base plate structure concrete; a bank slope covering layer is arranged at the top of the bank slope; a steel bar gabion is arranged on the surface of the bank slope covering layer; and a steel bar mesh, arranged vertically, is arranged between the base plate structure concrete and the backfill concrete. The construction method comprises the steps of excavating a tooth groove, binding structural steel bars, positioning a steel bar mesh, pouring in a first stage, supporting and protecting a template, pouring in a second stage, paving a steel bar gabion, disassembling the template and shaping. Through the concrete tooth groove stilling pool and the construction method thereof, construction process is accelerated, construction procedure is simplified and engineering investment is saved, so that the concrete tooth groove stilling pool and the construction method thereof are suitable for being widely popularized and used.

Description

technical field [0001] The invention relates to the technical field of hydropower engineering construction, in particular to a concrete alveolar stilling pool and a construction method thereof. Background technique [0002] As an important part of hydraulic structures in hydropower projects, stilling pools have the functions of dissipating water flow energy, preventing river bed erosion, and protecting downstream buildings. Its structure is often composed of guide walls, pool floors, tail sills, and downstream aprons. The bottom plate of the stilling tank and the tail sill are usually connected as one, and the energy dissipation of the water flow is basically completed in this section. The impact force of the water flow on the bottom plate of the stilling tank is very large. Alveolar, so that both ends of the base plate are embedded in the bedrock of the river bed. In order to save material costs, the space other than the alveolar structure concrete is usually backfilled wi...
