Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Below in conjunction with concrete accompanying drawing, realization of the present invention is described in detail.
Embodiment 1
Specific embodiments of the invention 1 as shown in Figure 1 to 4, a kind of underground water level precision adjustment system on earthen archaeological site, comprise the enclosed sealing containment system 1 that earthen ruins and extraneous underground water can be completely cut off substantially, also comprise deep layer flow guide system 2 and irrigation and drainage system 3, deep layer flow guide system 2 is positioned at sealing containment system 1, and is connected with irrigation and drainage system 3.
In the present embodiment, sealing containment system 1 comprises impervious wall 11 and is positioned at the gutter, top layer 12 of impervious wall 11 upper end, and at least one collecting well 13, and this gutter, top layer 12 is connected with collecting well 13.Deep layer flow guide system 2 comprises the permeable layer 21 being positioned at impervious wall 11 inwall and the diversion pipeline 22 be positioned at bottom impervious wall 11, and at least one irrigation and drainage well 23, this diversion pipeline 22 is arranged along the direction of going along with sb. to guard him of impervious wall 11, and diversion pipeline 22 is connected with irrigation and drainage well 23.Irrigation and drainage system 3 comprises the water-level observation instrument 31 be installed in irrigation and drainage well 23 and the irrigation and drainage facility 32 be connected with external pipe.The lower end of impervious wall 11 is short stepped in foreign minister, and diversion pipeline 22 is located on the inner side step face of impervious wall 11 lower end.The step surface of medial and lateral can flush if desired.Under some specific condition, without diversion pipeline 22, and directly permeable layer 21 can be connected with irrigation and drainage well 23.
In the present embodiment, impervious wall 11 cross section of sealing containment system is rectangular, arranges an irrigation and drainage well 23 in this rectangle impervious wall 11 at a certain distance, and impervious wall 11 is outer arranges a collecting well 13 at a certain distance.Collecting well 13 is positioned at the upper end of impervious wall 11, and collecting well 13 is all connected with drainage plant 14 with gutter, top layer 12.Permeable layer 21, for being covered with the vertical permeable layer of impervious wall 11 inwall, adopts geotextiles or other seepage material.Impervious wall 11 can adopt other impervious material such as concrete or steel plate.
Operating principle of the present invention is as follows: impervious wall 11 can by earthen ruins and extraneous underground water substantially isolated, first unnecessary underground water in earthen ruins infiltrate the permeable layer 21 inside impervious wall 11, then enter diversion pipeline, enter in irrigation and drainage well 23 through diversion pipeline 22 water conservancy diversion.When the height of water level in comb well 23 exceedes the height of water level preset, irrigation and drainage system 3 starts, and is discharged by unnecessary water.When seasonal variations or external environment condition change cause the groundwater table of earthen ruins on the low side, irrigation and drainage system 3 starts, enter in irrigation and drainage well 23 from outside moisturizing, and then enter diversion pipeline 22 and permeable layer 21, finally enter in the scope of earthen ruins, groundwater table is raised, thus reaches the object regulating groundwater table.
Embodiment 2
Specific embodiments of the invention 2 as shown in Figure 5, with embodiment 1 difference are, the interior zone of earthen ruins is also provided with the some shallow-layer french drains 5 for accelerating seepage velocity, and the end of shallow-layer french drain 5 all extends to the permeable layer 21 inside impervious wall 11.
The operating principle of the present embodiment, with embodiment 1.Unlike, when by the underground water of earthen ruins inside discharge or when pouring into, shallow-layer french drain 5 can be increased work efficiency greatly.The earthen ruins large for some Area comparison or soil layer seepage of water is more weak, is especially applicable to arranging shallow-layer french drain 5.
In the above embodiments, the flat shape of the impervious wall 11 of sealing containment system can be rectangle, circle, polygon or other is irregularly shaped, the height of impervious wall 11, the quantity of irrigation and drainage well 23 and position, the quantity of shallow-layer french drain 5 and position, can arrange according to the site environment of earthen ruins, to reach best result of use for final purpose.
The above embodiments are only the preferred embodiments of the present invention, can not limit interest field of the present invention with this, and therefore, the equivalent variations done according to the present patent application the scope of the claims, still belongs to the scope that the present invention is contained.
