Description

French drain on the outside of a kind of basement retaining wall

Technical field

The utility model relates to french drains on the outside of basement construction technical field more particularly to a kind of basement retaining wall.

Background technique

In Basement Concrete Structures construction, generally drained by the way of bright ditch and sump, but work as exterior wall After the completion of backfill, this drainage pattern will be unable to effectively exclude underground water, causes water level on the outside of basement to increase, is very easy to make At the generation of anti-floating accident, to influence the quality and safety of major structure of construction.

In the prior art, Authorization Notice No. is the Chinese patent of CN203741856U, is disclosed outside a kind of outer wall of basement Side weeper drain.French drain is layer structure, is built on the outside of outer wall of basement on bed course, is followed successively by coarse sand drainage layer from outside to inside With rubble pervious bed, coarse sand drainage layer and rubble pervious bed are separated by side with brick wall, are separated by top surface with geotextiles.Its institute is public Weeper drain on the outside of the outer wall of basement opened can effectively exclude underground water, reduce the water level on the outside of basement, reduce to building The water pressure for building main body concrete structure solves the technical problem drained after exterior wall backfill, ensure that major structure of construction Quality and safety.

But in the utility model, french drain is directly communicated with drainage pipeline, the rubble or impurity contained in french drain Content is excessive, and when the water in french drain being discharged by drainage pipeline using draining pump, drainage pipeline is easy to happen blocking.

Utility model content

The purpose of this utility model is to provide french drains on the outside of a kind of basement retaining wall, have impurity screening, the row of reduction The advantages of waterpipe blocks.

The above-mentioned purpose of the utility model has the technical scheme that

French drain on the outside of a kind of basement retaining wall, the french drain ontology including earth-retaining wall outer side is arranged in, the french drain sheet Body is provided with collecting-tank far from the side of the earth-retaining wall, and the french drain body bottom portion is connected to the collecting-tank, the collection Pond, which is provided with, filters the filter assemblies that the french drain ontology flows into the collecting-tank infiltration, is provided with and is used on the collecting-tank The component that draws water of collecting-tank draining.

Implement above-mentioned technical proposal, the external infiltration of basement retaining wall is entered in french drain underground water is discharged, dropped Low groundwater level, entering in collecting-tank in french drain, by filter assemblies filtering rubble, soil etc. in collecting-tank, then Filtered infiltration is discharged by drawing water component, reduces directly by filtered infiltration by the component discharge that draws water, causes The case where component that draws water blocks.

Further, the collecting-tank is constructed by concrete.

Implement above-mentioned technical proposal, the collecting-tank constructed by concrete reduces the infiltration stored in collecting-tank and is lost, makes The infiltration for obtaining collecting-tank may be used as urban afforestation water or fire demand water by the component discharge that draws water into after filtering.

Further, the bottom of the collecting-tank is lower than the bottom of the french drain ontology.

Implement above-mentioned technical proposal, the bottom of collecting-tank is arranged lower than the bottom of french drain ontology, so that french drain ontology In infiltration can smoothly enter into collecting-tank, while can increase the collecting water from runoff of collecting-tank, at rainy season, french drain infiltration increases, and collects More infiltrations can be stored in pond, are prevented infiltration because not being discharged in time, are accumulated in earth-retaining wall outer side.

Further, the filter assemblies are provided with sand stone layer, coarse sands layer, fine sand layer and work along water falling direction from top to bottom Property layer of charcoal.

Implement above-mentioned technical proposal, can be incited somebody to action by the setting of sand stone layer, coarse sands layer, fine sand layer and active carbon layer from top to bottom The impurity that water band from sedimentation basin comes is filtered and adsorbs, and filtered water may be used as city after being discharged by the component that draws water City's greening water or fire demand water improve the utilization rate of infiltration.

Further, the component that draws water includes water pump and drainpipe, and the water pump passes through drainpipe and the collecting-tank phase Even, the least significant end of the drainpipe passes through the top that the bottom of pond portion of catchmenting is arranged in the filter assemblies.

Implement above-mentioned technical proposal, the least significant end of drainpipe is arranged between filter assemblies and bottom of pond portion of catchmenting, is passed through Water pump facilitate will in collecting-tank by filtered water discharge again plus utilize, the least significant end of drainpipe not with the minimum termination of collecting-tank Touching, the silt for reducing bottom of pond portion of catchmenting are discharged by drainpipe.

Further, the bottom end of the drainpipe is provided with the strainer for covering the drainpipe pore.

Implement above-mentioned technical proposal, because infiltration is also accompanied with some silts and little particle after filtering by filter assemblies Impurity is provided with strainer in the bottom end of drainpipe, reduces the discharge of impurity to the greatest extent, so that the infiltration after discharge can be directly used for Urban afforestation water or fire demand water.

Further, the french drain body bottom portion and the collecting-tank connectivity part are provided with the infiltration prevented in the collecting-tank Flow backwards the check-valves into the french drain.

Implement above-mentioned technical proposal, by being provided with check-valves in connectivity part, prevents excessive, the collecting-tank that seeps water at rainy season In water fail to be discharged in time, the water in collecting-tank covers junction and enters in french drain, causes the external lateral seepage heap of retaining wall Product.

Further, sludge pump is provided on the collecting-tank, the sludge pump passes through sludge pipe and the bottom of pond portion of catchmenting It is connected.

Implement above-mentioned technical proposal, because seeping water can also accumulate over a long period into after filtering with some silts and small impurity It can cause to accumulate in bottom of pond portion of catchmenting, the infiltration that may result in draining blockage or discharge is muddy, needs treated It can utilize.

In conclusion the utility model has the following beneficial effects:

One, the water in french drain enters in collecting-tank, by filter assemblies filtering rubble, the soil etc. in collecting-tank, then Filtered infiltration is discharged by drawing water component, reduces directly by filtered infiltration by the component discharge that draws water, causes The case where component that draws water blocks;

Two, the setting by sand stone layer, coarse sands layer, fine sand layer and active carbon layer under through-hole from top to bottom can be by water from heavy The impurity that band comes in the pond of shallow lake is filtered and adsorbs, and filtered water may be used as urban afforestation after being discharged by the component that draws water With water or fire demand water, the utilization rate of infiltration is improved.
