Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
A kind of abductive approach for improving water-permeable brick ground moisture infiltration rate of the present invention, is specifically implemented according to the following steps:
Step 1, according to localized ground situation and construction needs are implemented, ground is subjected to checkerboard type division；
Step 2, selected to arrange induction packet specification according to the size of checker；
Wherein, induction packet be cuboid, and induce packet length and width it is equal, induce the length of packet and width be 0.08m~
0.4m, inducing high h=0.15m~0.25m of packet, the side length L of each checker is 1m~5m；
Induction packet the preparation method comprises the following steps:
Step a, using stainless steel welded cuboid skeleton, later by the inner bottom surface of cuboid skeleton and four insides
Face is laid with using metallic sieve, and metallic sieve and cuboid skeleton are welded；
Metallic sieve is 4 mesh metallic sieves；
Stainless steel is 304 stainless steels, 304L stainless steel or 400 stainless steels；
Step b is laid on MIcroporous polyolefin film is smooth on metallic sieve, and is carried out using binder in seam crossing close
Envelope, forms open-topped cuboid film layer；
The manufacturer of MIcroporous polyolefin film is Nantong Kangka Complex Material Co., Ltd.；
Bridge formation polyethylene glycol oxide layering uniform compaction is filled in cuboid film layer, uses polyolefin later by step c
Microporous barrier is sealed the top surface of cuboid film layer, and seam crossing is sealed using binder, finally, by metallic sieve
It is covered on the top surface of cuboid skeleton, and is welded with skeleton, complete induction packet is formed；
Wherein, Soft Soil soil weight γ is tamped in the filler density p of bridge formation polyethylene glycol oxide and implementation localized ground
Between relationship are as follows: the γ of ρ=0.73；
The packed height of bridge formation polyethylene glycol oxide is consistent with the height of cuboid film layer；
The molecular weight of bridge formation polyethylene glycol oxide is 20,000,000；
Metallic sieve is 4 mesh metallic sieves；
Step 3, induction packet landfill: induction packet is dug in each checker and places hole, landfill induction packet；
Wherein, the landfill depth of packet is induced are as follows: induction bag top should be lower than compacting weak soil primary surface 2-10cm；
Place the height of the depth not less than induction packet in hole；The diameter for placing hole is 1.2-1.4 times of diameter of induction packet；
The principle of the present invention are as follows:
According to classical physics, the energy that substance has can be divided into kinetic energy and potential energy, and soil water movement speed is slower,
The kinetic energy of soil moisture is not considered generally, therefore soil moisture potential typically refers to its potential energy.Gesture possessed by soil moisture
Gravitational potential, matric potential, pressure potential and solute potential can be divided into.Total soil water potential is point gesture that all motive powers generate in soil
Summation, as shown in formula (1):
In formula (1),For total soil water potential,For matric potential,For solute potential,For pressure potential,For gravitational potential,
For temperature potential；
When not generating rainfall infiltration, the outer compacting Soft Soil soil of induction packet is unsaturated state, WithIt is right
The influence of soil water movement is negligible, the potential energy havingAs shown in formula (2):
Induction packet internal potential energy when being laid with according to pervious surface the compacting Soft Soil soil weight be designed forSuch as formula (3)
It is shown:
Rainfall is being generated, when moisture reaches compacting Soft Soil soil by water-permeable brick, outer soil moisture content is wrapped in induction
Increase, matric potentialIncrease, potential energyIncrease, and induces packet internal potential energy since special permeable membrane acts on, potential energyIt still keeps not
Become, induction packet is inside and outside at this time forms potential energy difference, as shown in formula (4):
Then presence of the soil moisture because of potential energy difference, the place high from the potential energy place movement low to potential energy, as shown in figure 4,
Induction packet is vertically embedded in the compacting Soft Soil soil below water-permeable brick by the present invention, so that horizontal direction potential energy difference is persistently deposited
It is playing a role jointly with vertical direction potential energy difference, induction water-permeable brick surface moisture is lower rapidly to be seeped, and it is permeable to significantly improve water-permeable brick
Performance.
It induces on packet method for arranging, according to permeable region area, ground is subjected to checkerboard type division, and each checker
Side length L be 1m~5m, zygotic induction packet coverage determines induction packet specification, and each individually induction packet has certain
Control range, in horizontal one-dimensional direction, inducing packet controlled range is approximately the square region of a side length a, induces packet control range
It is related with its specification, relationship between induction packet control area side length A and the long a of induction packet, as shown in formula (5):
A=18.75a (5)；
It is a that the basic specifications parameter of induction packet, which includes: long and width, is highly h, inside stuffing density p.In implementation process
When middle resultant effect is preferable, relationship between the packet zone of control side length A and side length L of each checker is induced, such as formula (6) institute
Show:
A=1.5L (6)；
In turn, convolution (5) can obtain relationship between induction bound edge long a and the side length L of each checker, such as formula (7)
It is shown:
A=0.08L (7)；
In addition, our experiments show that, induction packet height h scope control is preferable in 15cm-25cm, can need to carry out according to implementation
Selection.H is in the range, it then follows higher, the better rule of effect of height.When h is less than 15cn, induction holding supervention waves action time
Shorter, effect is undesirable.Seeping when h is greater than 25cm, under soil moisture to the time at depth 25cm is more than 72 hours, the long period
Actual demand is not met, and height is excessive that the negative effects such as constructional difficulties is caused to be greater than its advantages.
According to soil water movement potential energy principle, design induction packet internal potential energyWith external soil potential energyAnswer it is equal, then
Relationship when inside stuffing density p and pervious surface are laid between compacting Soft Soil soil weight γ, as shown in formula (8):
The γ of ρ=0.73 (8)；
In landfill individually induction packet, placement hole depth is consistent with induction packet height, and placement effluent plane side length is to induce
Packet diameter is slightly larger, i.e., places induction packet with enough positions, in order to avoid destroying rammed soil type of foundation stability, pervious surface is caused to collapse etc. no
Good consequence, and the bulk density for backfilling soil should keep consistent with surrounding soil bulk density.
