Post installs flood control baffle plate 20 with offering mounting groove 19 on center pillar 18 in mounting groove 19；During center pillar and side column are respectively arranged below with
Column foundation 21 and side column basis 22, middle column foundation 21 and side column basis 22 are Extended chemotherapy I, center pillar basis top and center pillar bottom
Between be provided with center pillar built-in fitting 23, side column built-in fitting 24 is provided between side column basis top and side column bottom；Below Extended chemotherapy
Provided with blinding layer, respectively center pillar blinding layer 25 and side column blinding layer 26, center pillar blinding layer 25 and side column base mat
Where the lower end on height where being highly less than the lower end of bottom cushion 1 where the lower end of layer 26, middle column foundation 21 and side column basis 22
Highly it is located at sustained height with the upper end of bottom plate 6 less than height where the lower end of bottom plate 6, basic 22 upper ends of middle column foundation 21 and side column；
Cistern be provided with discharge water, inlet and outlet pipe lines, ceiling is erected above cistern.
The permeability test method of portable anti-flood wall, comprises the following steps：
1st, proving ground build
（1）Build the bottom plate of proving ground：Smooth location, bottom cushion, middle column foundation are carried out on smooth good place
Bed course and side column blinding layer pour；Progress reinforcing bar is poured in bottom cushion, center pillar blinding layer and side column blinding layer to tie up
Prick, welding, reserve the space of center pillar built-in fitting and side column built-in fitting, wait middle column foundation and side column basis to be installed again after the completion of casting
Center pillar built-in fitting and side column and built-in fitting are mounted directly center pillar built-in fitting in the space of center pillar built-in fitting and side column built-in fitting
With side column built-in fitting；Bottom plate, middle column foundation and side column basis pour C25 concrete using using logical storehouse continuous placing mode, and
28d ages are conserved, complete the construction of bottom plate, middle column foundation and side column basis；Built above the center pillar built-in fitting of middle column foundation
Center pillar, side column is built above the side column built-in fitting on side column basis；Center pillar built-in fitting basis length × width × height be 10.4 × 1.2 ×
1.0m, side column length × width × height are 0.8 × 0.8 × 2.4m；
（2）Build cistern：Cistern is built on bottom plate, cistern is built on bottom plate, builds the reinforcing bar of cistern
Concrete wall, reinforced concrete wall are thickness 250mm standard reinforced concrete U-shaped shear wall, and the height of reinforced concrete wall is 2.4m, cistern
Useful storage area about 30.745m2, when water storage is to design height 1.8m, cistern volume is about 55.341m3, in side column with
Installation flood control baffle plate between post；
（3）Installation cistern is discharged water, inlet and outlet pipe lines, and ceiling is erected above cistern, is completed proving ground and is built；
2nd, water-storing test is carried out
Water storage is carried out to cistern, when water storage is to 1.78m, starts leak test, 1.75m is down to through 3h water levels.With 1.75m
For 0 moment, the observation frequency once, is stopped for 6h ~ 12h to 150h.Hereafter, observed stage is 1.37m to 300h again.Measured water level is with seeing
The relation for surveying the time is as shown in Figure 4.
（1）
In formula, H is water level, m；T is the time, when h, wherein t=0, H=1.75m；
Utilize formula（1）Fitting, coefficient correlation is formula（1）With the degree of fitting of measured data up to 0.995, fitting effect
It is good.In order to further verify the accuracy of the relational expression, forwardly and rearwardly predicted respectively.Result of calculation shows, pushes away forward
3h（T=- 3h during calculating）, calculated value 1.784m（Measured value 1.78m）, backward to 300h, calculated value 1.369（Measured value
1.37m）, as a result it coincide good.It follows that this portable anti-flood wall is as standard product, its water level as caused by seepage
Decline is made up of two parts, seepage critical groundwater table 1.327m.Seepage critical groundwater table is the water that seepage critical groundwater table refers to that leakage is 0
Position, by different height water level, the leakage of anti-flood wall, leakage and the numerical relation of height of water level are fitted, form formula
Afterwards, the water level that leakage is zero, as seepage critical groundwater table are instead released, i.e., when water level is less than seepage critical groundwater table, flood control
Wall leakage is 0.
At present, the leakage rule of portable anti-flood wall still lacks research both at home and abroad, and its seepage typically only occurs in contact position
Put, that is, control flood between baffle plate and center pillar, side column, between flood control baffle bottom and bottom plate and between baffle plate and baffle plate etc..In view of
Existing experimental condition, each several part leakage are difficult to obtain respectively by experiment.Ignoring pond face moisture evaporation influences, movable type flood control
Wall leakage is calculated as follows：
（2）
In formula, q is leakage, L/h；A is sump area, m2, tests A=30.745m2 herein；V is percolation flow velocity, m/h,
v=dH/dt。
By formula（1）Derivation obtains percolation flow velocity, substitutes into formula（2）Average leakage change rule are calculated under different water levels
Rule, and compared with the average leakage after measured water level conversion, such as Fig. 5.From Fig. 4 and Fig. 5, water level is more than 1.5m
When, the range of stage of the anti-flood wall is fast, leakage is big, and in more than 50L/h, when water level is more than 1.7m, leakage can exceed
300L/h。
Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as
The scope of protection of the utility model.
