Cut the dirty borehole wall, the shaft bottom is built up by steel concrete, establishes well lid in the middle of the steel concrete of Jing Ding, the other security guardrail that is provided with of well lid.

Described stormwater overflow mouth place is provided with show events gate opening situation rule.

The utility model has the advantages that:

1) the smooth problem of solution storm-water drainage: because the gate form of employing movable can change the overfall actual elevation with this, thereby the control excess flow guarantee storm-water drainage according to the corresponding lifting of instant rainfall size, reduction gate sheet height.Between storm period, gate can also be opened fully (maintaining an equal level) downwards with stormwater overflow mouth bottom line, be placed into fully below the dirty mixed flow inlet pipeline of the rain flowing water point, the rain volume exhaust is stopped upstream area waterlogging problem with this when guaranteeing heavy rain;

2) can be by real control retaining power: because, adopt the gate form of movable, can be according to the instant corresponding lifting of discharge of sewage size, reduce the flashboard height, the control retaining power.On this basis, can also set up according to actual needs and cut dirty lift pump, further satisfy and cut dirty needs, assurance cuts thoroughly dirty and don't makes the function surplus;

3) scope of application is not limited by the region: can guarantee to cut under the dirty effect prerequisite, according to corresponding lifting of local river level absolute altitude or reduction flashboard height, guarantee the isolated of river level and wastewater level.It is lower to solve physical features, and the dirty pipeline absolute altitude of rain is crossed low problem, helps also applying than low country in physical features.
