The bottom in ditch, just can be fixed to prefabricated water discharge member, easy for installation.
The utility model is further arranged to：The foundation ditch corner is provided with sump, and the sump is provided with protection
Column.
By using above-mentioned technical proposal, guard rail is set on sump can avoid staff from checking the Well Water Level that catchments
Shi Bushen falls into sump, using safer.
The utility model is further arranged to：Centre position of the gutter between adjacent sump is provided with highest
Point, gentle incline is provided between the sump of peak to both sides.
By using above-mentioned technical proposal, gutter is easy to ponding to be collected to collection to having certain slope between sump
In well.
The utility model is further arranged to：The upper edge edge of the foundation ditch is provided with intercepting ditch.
By using above-mentioned technical proposal, intercepting ditch can stop the rainwater of earth's surface, it is to avoid rainwater is flowed backward in foundation ditch, is easy to
The discharge of surface rain.
The utility model is further arranged to：Also include water pump and drainpipe, drainpipe is connected to sump and intercepting ditch.
By using above-mentioned technical proposal, the ponding in sump is entered into intercepting ditch by water pump, will product by intercepting ditch
Water is emitted at a distance, without setting long drainpipe.
In sum, compared to existing technology, the utility model not only can play effective support to the furrow bank in gutter
Effect, and does not influence the pore water at the furrow bank of gutter to discharge, also with it is easy for installation the characteristics of.
