Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
As shown in the figures 1-2, the stilling pool structure of the utility model is divided into an upstream concrete apron 1 and a downstream tail bank 6, the upper part of the bottom plate of the concrete apron 1 is a horizontally arranged copper water stop 4, and a horizontal copper water stop 4.1 and a vertical copper water stop 4.2 are arranged in the concrete apron 1 and the structural joint 2 between the concrete apron and the surrounding buildings; and the vertical copper water stops 4.2 at the peripheral edges of the stilling pool structure are inserted into the water stop base 7. (the conventional asphalt shirt board 8 is pre-installed on the two sides of the structural joint 2, the copper seal 4 is wrapped with asphalt hemp threads 9, and the gravel material 10 is padded below the drainage perforated pipe 3.)
The outer layer of the concrete apron 1 is provided with a drainage perforated pipe 3 wrapped with geotextile, and the drainage perforated pipe 3 is arranged along the transverse longitudinal structural joint 2 in the horizontal direction and communicated with a drainage gallery 5. The tail ridge 6 is internally provided with a water discharge perforated pipe 3.
Example 1: as shown in fig. 1-2, the stilling pool is composed of a concrete apron 1 and a tail sill 6, a horizontal copper water stop 4 is arranged at the position of a structural joint 2 at the upper part of the concrete apron 1, and vertical copper water stops 4.2 are inserted into a water stop base 7 at the peripheral edge of the stilling pool. The drainage floral tube 3 is arranged at the bottom of the concrete apron 1 along the structural joint 2 in the horizontal direction and is communicated with a drainage gallery 5 in the tail sill 6, and the drainage gallery 5 is provided with the drainage floral tube 2 leading to the downstream of the tail sill 6.
Referring to FIGS. 1-3: a closed self-draining stilling pool structure comprises a concrete apron 1 positioned at the upstream and a tail sill 6 positioned at the downstream;
copper water stops 4 are arranged in the structural joints 2 between the surrounding buildings and the concrete apron 1,
the copper water stop 4 is respectively arranged in the concrete apron 1 and at the peripheral edge of the concrete apron 1;
a drainage floral tube 3 which is mutually communicated along the transverse direction and the longitudinal direction is embedded in advance under the concrete apron 1,
