Two are had, two sumps 5 are respectively arranged at the two ends of the sidewall bottom of intermediate layer step 12, the lower end point of two water pipes 8
Do not extend in two sumps 5, self priming pump is provided with two sumps 5, the other end of two water pipes 8 is extending basement just
In the cistern 7 set on negative zero top plate face 6, the water that water pipe 8 is arranged in the inner side of outer wall of basement 3, cistern is used for garden
Woods is watered flowers and toilet water, reaches the purpose of the recycling of water resource, reduces the waste of water resource.
Weeper drain 4 includes pvc pipe 41, coarse sand loaded filter 42, cobble loaded filter 43 and blotter 44, blotter 44
French drain bottom is layed in, length direction of the pvc pipe 41 along weeper drain 4 is arranged at the top of blotter 44, and cobble anti-filter
Layer 43 and coarse sand loaded filter 42 are coated on the outside of pvc pipe 41 successively；
1st, component and fitting size design
The diameter of pvc pipe 41 is divided to two kinds：The caliber of pvc pipe 41 is in corresponding weeper drain at the absolute altitude of top layer step 13
The caliber of pvc pipe 41 is 400mm in corresponding weeper drain at 300mm, the absolute altitude of intermediate layer step 12, at the absolute altitude of bottom step 11 pair
The caliber of pvc pipe 41 for the weeper drain answered is 400mm；
Cistern 7 is water tank (6000mm (length) × 6000mm (width) × 2000mm (height))；
Sump 5 (5000mm (length) × 5000mm (width) × 3000mm (height))；
Water pipe 8 is diameter 200mm fire extinguisher canvas hose.
2nd, operating method
For the exterior wall blind ditch construction in whole foundation ditch be divided into blind ditch construction at high bottom plate, blind ditch construction at central floor panel,
Blind ditch construction at low bottom plate.Blind ditch construction in this 3rd area can organize the construction method of parallel construction.Simultaneously to this three region
Basement bottom board exterior wall at french drain is excavated by the way of hand digging.
Before excavation, spill lime survey along the timber of measurement group setting-out and set absolute altitude, then excavated with excavator along lime line, to control
Make linear and depth.Foundation pit earth is transported in time, then carries out manual amendment foundation ditch according to the lime line of setting-out and the measurement of the level.Open
It should be noted that the gradient, cross dimensions, the depth of groove during digging.After groove is dug, it is necessary to which groove is detected.And by inspection
Afterwards, the construction of french drain ditch body is carried out by Fig. 3.Then filled on the top of french drain with plain soil or clay, be filled to design and specify
At absolute altitude.
For the processing plugged into of french drain at high-low bay, two pipes are entered in high-low bay foundation ditch connection using pvc pipe elbow
Row connection, is 300mm for pvc pipe caliber in french drain at high base surface absolute altitude；Pvc pipe pipe in french drain at the absolute altitude of central floor panel face
Footpath is 400mm；The pvc pipe caliber of french drain is 400mm at low base surface absolute altitude.
Sump is excavated by design attitude, the size of sump is 5000mm (length) × 5000mm (width) × 3000mm
(height).After the completion of sump is excavated, complete the reinforcing bar colligation of bottom of pond plate and side wall by design requirement, it is qualified by inspection after, pour
Underplate concrete (wherein concrete will have certain impermeability), configures self priming pump in sump.
Header tank is set by design requirement in the positive and negative null range of annex top plate, the size of water tank for 6000mm (length) ×
6000mm (width) × 2000mm (height), side wall uses armored concrete, constructed by design requirement, for the anti-of water tank bottom
The build of water layer, it should meet design waterproof requirement, the waterproof of water tank bottom and side wall is set on request.
By self priming pump, water pipe is set along underground external wall, the ponding in sump is evacuated to by top by water pump respectively
In water tank, the water collected in the water tank on top is connected, directly with the toilet water system of water for afforestation and part annex
Watered flowers and toilet water for gardens, so as to reach water reuse purpose.
The thought of fusion " drop row combines ", it is shallow to meet groundwater level depth, stepped ramp type is formed in Excavation Process high
It is low across the new drainage measure of foundation ditch, reach cost-effective draining purpose, this measure is not only simple in structure, quick construction,
It is safe and reliable, and the problem of thoroughly solve deep basal pit high-low bay draining, construction cost is greatlyd save, improve construction effect
Rate, it is to avoid situations such as basement seeps water.
Again, water resource, as an important component of whole ecological environment, is both influence economic civilization life, city
Relation of the flourishing restraining factors in city again with weather, weather is very close.Secondary utilize of water resource is particularly important.
The underground water that french drain collection comes is subjected to secondary utilization, fusion environmental protection and water-saving ideas, for the sustainable development of engineering, had
Very strong impetus.
