Description

The larger seepage treatment structure of a kind of diaphragm wall
Technical field
The utility model relates to the larger seepage treatment structure of a kind of diaphragm wall, belongs to underground engineering field, and the leak stopping that is applicable to the larger seepage of underground continuous wall seam is processed.
Technical background
Diaphragm wall is to utilize trench machine, by means of the retaining wall effect of mud, digs out narrow and dark groove underground, and pour into a mould suitable material within it and form have together antiseepage, the continuous underground wall body of gear soil and weight-bearing function.Diaphragm Wall originates from Europe, is to use the method for mud and tremie concrete to grow up according to well-digging and oil drilling, and the initial stage, reservoir is underground to dam for dam body seepage, after develop into part or all of retaining wall, underground structure.The deep layer basement in house, underground parking, underground street, underground railway, underground warehouse, mine etc. all can be used.Nineteen fifty Italy's beginning is used Diaphragm Wall in the reservoir dam engineering, China in 1958 has introduced technique and has been applied in the construction of Beijing Miyun Reservoir, the mid-1970s, this technology begin to promote the use of the departments such as building, colliery, municipal administration in China.
Diaphragm wall can be divided into reinforced concrete wall, plastic concrete wall, hardened slurry wall, starch wall, dry wall, mud ditch wall, post-tensioned prestressing diaphragm wall, steel diaphragm wall etc. from stiff mud by strong body material, and wherein reinforced concrete wall is most widely used at present.Diaphragm wall is as the ingredient of Main Underground body structure, must be forever durable, structural entity without ooze, without leak, stress equalization, its construction has following characteristics: (1) vibrations are little, noise is low, wall stiffness is large, barrier performance is good, to ground undisturbed on every side, can form and have very that the arbitrary polygon diaphragm wall of large bearing capacity replaces pile foundation, open caisson foundation or laying foundation; (2) accommodation to soil is very wide, all can construct in the ground of the alluvium of weakness, medium ground, closely knit sandy gravel stratum and rock.
But under some special geological conditionss, such as very soft mucky soil, the alluvium that contains erratic boulder and superhard rock etc., difficulty of construction is very large, the problem that adjacent wall section can not be alignd and leak may appear, Seepage generally can be divided into a leakage, line leakage, three kinds of forms of face leakage, and its seepage degree basically can be divided into infiltration, leak, gushes slime water etc.Cause the reason of continuous diaphragm wall seepage more, as: joint is not cleaned with water totally, the body of wall joint collides or gnaws bad, joint is uneven, the differential settlement of diaphragm wall has caused the relative sliding of seam crossing, new and old diaphragm wall concreting is long blanking time, and construction technology is different, and the joint ess-strain is undergone mutation and caused occurring the crack and infiltration etc. during the diaphragm wall excavation.Leak for not too serious some leakage, face, use first artificial removal of contamination, cutter removes the loosening stone of concrete surface, and water is clean with surface clean, dabbing, and cement mortar or the concrete of then selecting the super early strength expansive cement of aluminium sulfate and a certain amount of medium coarse sand to be mixed with are repaired.The reparation Chang Shouxian that line leaks carries out slot and tick slot to the place of leaking, and namely manually repairs groove, then rinses folder mud and the impurity of leakage well with clear water, secondly groove is carried out dabbing, drainage and shutoff.Leakage and sand boil is serious and may jeopardize foundation ditch or Adjacent Buildings when safe when running into, and should take urgent measure, and it is processed.
Need at present that invention is a kind ofly tempered toughness with gentleness badly, stifled row is in conjunction with the larger seepage treatment structure of diaphragm wall of, multi-way prevention.
Summary of the invention
The purpose of this utility model is to adopt tempers toughness with gentleness, stifled row combination, multi-way prevention, ends the principle of controlling afterwards first, invent a kind of fast sealing, plugging effect is good, reparation is rear and the larger seepage treatment structure of diaphragm wall of former underground diaphragm wall bonding strength height, good integrity.
In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:
The larger seepage treatment structure of a kind of diaphragm wall is characterized in that forming the V-type notch in leakage along wall seam dabbing, and each evenly arranges the oblique reinforcing bar that sockets more than one V-type groove both sides; Fixedly behind the PE foam strip, ejection for water plugging forms the injecting paste material obturator in the V-type notch, inserts perpendicular to its lateral surface to connect joint bar before injecting paste material solidifies; Spray early strength micro expansion concrete coating in the injecting paste material obturator outside, and set gradually weather board, waterproofing course at its lateral surface; Apply the float coat sealing in the waterproofing course outside.
The material that float coat adopts is Polypropylene Fibers Cement Mortar, and steel fabric sheet is set in wiping one's face;
The oblique reinforcing bar that sockets is perpendicular to the dabbing metope; The surface that connects joint bar injecting paste material obturator.
The structure that the utility model relates to has following effect and advantage:
(1) by the setting of PE foam strip, injecting paste material obturator, can realize the larger leakage fast leak-stopping of underground continuous wall seam.
(2) by the setting of weather board and waterproofing course, realize arranging first rear defence, multi-way prevention, realize good plugging effect.
(3) by socketing the setting of reinforcing bar and steel fabric sheet, improved the leak stopping part and be connected with the high-wall of diaphragm wall, can make its cooperative bearing, avoid further carrying out of leakage wall seam, improved globality and the durability of diaphragm wall.
