Abstract
The present invention relates to a fully closed cave internal anti-leakage method. The present invention is characterized in that the present invention has four technological procedures that during the first technological procedure, channels are constructed for drainage at the water leakage points on the cave ceiling and the cave wall; during the second technological procedure, anti-leakage coiled material layers are arranged for leakage protection; during the third technological procedure, a fully closed, light and wall type steel reinforced concrete thin shell of which the surface is coated with waterproof paint to prevent small leakage from occurring during laying the coiled material is arranged. The present invention has good leakage protection effect, basically prevents water source from leaking into caves from the cave wall, greatly reduces the indoor humidity of the cave, and protects the equipment in the cave from corrosion and rustiness.
Description
The present invention relates to the fully-enlosed cave internal anti-leakage method of the stifled row of a kind of underground chamber combination, it belongs to the underground engineering inner waterproofing process field.
At present, both at home and abroad underground chamber inner waterproofing method have stifled, stifled be divided into again outer stifled and interior stifled two kinds, outer stifled be to stop up the possible water source that leaks on place, cavern massif surface; The interior stifled hole wall country rock boring that has in the hole is pressed in the hole or the notes waterproofing mortar, or is coated with the high performance water proof chemical liquid agent, with the obstruction leak paths; Or in the cavern, be coated with high-performance waterproof paint.Another kind of way is row, arranges also to be divided into to efflux and two kinds of interior rows; Effluxing is by the surface drainage system to be set at the place, cavern, to reduce the water source that leaks in the hole; In row be built-in waterproof lining in the hole, i.e. leakproof coiled material layer, making leaks flows to outside the hole outside lining.A large amount of facts have proved, outer stifled all water sources that leaks of not stopping of conventional method; Because the crack is very complicated in the country rock, leak in the interior stifled normal stifled west, east that occurs, and leak in stifled east, west, hard to guard against.And interior row often is subjected to the restriction in space and existing facility in the hole, often is difficult to realize.
The objective of the invention is to provide a kind of fully-enlosed cave internal anti-leakage method, it not only builds the leakproof coiled material layer, also build the canal drainage, and serve as to support to build light-duty wall-attachment steel concrete leakproof lining, concentrated current are converged outside lining at the bottom of the inflow hole in the gutter from top to bottom with the hole wall.
The object of the present invention is achieved like this: comprise and build leakproof material layer 4, build the escape canal drainage of catchmenting along hole wall 1, and build light-duty, attached wall steel concrete shell 5: the escape canal nation of escape canal 2 is recorded by cement mortar; Light-duty, attached wall steel concrete shell 5 is made by gauze wire cloth, waterproofing mortar and water-repellent paint; Be connected and fixed with leakproof coiled material layer 4, hole wall 1 by bolt 3 steel concrete shells 5.
Because adopt such scheme, good leak-proof effect of the present invention can be stopped leakage, the drip source of hole wall in the hole substantially; reduce relative humidity in the hole greatly, reach equipment anticorrosion, antirust purpose in the protection hole, reduction is leaked, and relative humidity can reach 5%～10% in the hole; in addition, construction easily.
The present invention is described in more detail below by accompanying drawing and embodiment.
Fig. 1 is a generalized section of the present invention.
Among the figure: 1 hole wall, 2 cement mortar canal nations, 3 set bolts, 4 leakproof coiled material layers, 5 steel concrete shells.
Referring to Fig. 1; The embodiment of the invention has adopted the design principles of " the unimpeded combination is based on row ", has formulated the four roads totally-enclosed light-duty wall-attaching type leakproof technology of setting up defences, and its concrete practice is:
Promptly there is the row of guiding in first road for building the canal drainage, according to the specification of Dong Ding hole wall leakage point distribution situation and leakproof coiled material layer 4, in the hole and the hole wall is smeared cement mortar, form escape canal nation 2, make it both to play and control the flow direction effect of leaking, work to install stationary bushing again and pile up bolt 3 positions; The Dong Ding Dong Bi of present embodiment has four leakage points, then builds four escape canals.
Second road is Lou coiled material layer 4 leakproofs of setting up defences, and promptly lays the leakproof coiled material from top to bottom, is fixed in the escape canal nation with expansion bolt 3, and coiled material will overlap, and lap-joint is bonding with hot method.
The 3rd road is for establishing 5 protection of Totally-enclosed-type lightweight section reinforced concrete shell lining; facts have proved that top, hole coiled material layer 4 does not have braced structures; time one is long; amount of deflection increases; tear failure easily; in order to reduce the structural stability of coiled material layer amount of deflection and assurance leakage protective system; when the leakproof coiled material layer is installed; below coiled material, hang the layer of steel wire net; and smear the waterproof cement mortar of 2～3 cm thicks thereon, and make it to form light-duty, an adherent thin layer protecting steel reinforced concrete casing, be connected and fixed by bolt 3 and hole wall 1; make it both to rise the protection structure function, play the antiseepage effect again.
The 4th road antiseepage promptly after protective jacket on the light-duty reinforced concrete is fixed, is coated with water-repellent paint one on its surface, with sheltering leakage for a short time of stopping may occur in coiled material is laid, thereby accomplishes that leakage-proof and seepage-proof is perfectly safe.
