Description
Technical field
The utility model relates to a kind of leakage plugging structure, relates in particular a kind of diaphragm wall serious leakage plugging structure, belongs to underground engineering field.
Background technology
Development along with urban construction, highrise building, heavy construction and all kinds of underground installation are increasing, certainly will deepen its basis and bury underground, add the factors such as environment around of foundation construction scene and construction plant condition, going along with sb. to guard him of deep foundation ditch seemed to more and more important.And diaphragm wall is exactly structural wall as bracing of foundation pit wall and underground structure, it is a technology the most frequently used in present underground engineering construction.
Diaphragm wall excavation technology originates from Europe, according to well-digging and oil drilling, use the method evolving development of mud and tremie concrete to get up, first nineteen fifty has adopted slurry coat method construction of diaphragm wall at Milan, ITA, 50~sixties of 20th century, this technology was promoted at western developed country and the former Soviet Union, became effective technology in underground construction and Construction of Deep Foundation.
Diaphragm wall adopts and uses on the ground trench machine along the periphery axis of deep excavation project, under mud off condition, excavate out a long and narrow deep trouth, after clear groove, install reinforcing cage in groove, then builds up a unit groove section with tremie method underwater concreting with tremie method, carries out so piecemeal, underground, build up continuous steel concrete wall one, can not only be as intercepting water, antiseepage, load-bearing, water-retaining structure can also play the support action to Adjacent Buildings basis.The advantage of diaphragm wall has: Construction Vibration is little, wall stiffness is large, good integrity, speed of application is fast, can economize the cubic metre of earth and stone, can be used for building in intensive building deep foundation pit support and carry out reverse construction, can be used under various geological conditionss, comprising in sandy soil layer, the sandy gravel stratum below particle diameter 50mm and constructing etc.Be applicable to basement, underground store, parking lot, oil cellar, retaining wall, the deep foundation of highrise building, the reverse construction space enclosing structure of construction of buildings, the dark pond of industrial construction, hole, vertical shaft etc.
Yet undergroundly continuously due to self controllability, be easy to occur the situation of percolating water, cause serious quality problems, produce potential safety hazard.Cause the reason of underground continuous seepage to mainly contain following some reason: (1) adjacent two width subterranean wall perpendicularity deviations, cause two width diaphragm wall jags and occur larger space, there is percolating water, gush sand.(2) adjacent two width subterranean wall joint joints are not thoroughly processed (brush wall) totally, cause seam percolating water, gush sand.(3) concrete of not removing streams in the seam of subterranean wall, can form the channel of percolating water.(4) wall filling concrete process, due to collapse hole, body of wall folder mud, causes percolating water, gushes sand.
Present stage occurs that to diaphragm wall the close measure under slight seepage condition has a lot, and the impact of slight seepage is relatively little, general close measure is all comparatively reliable, but for the measure of the serious leakage occurring, existing leak-blocking construction method is difficult to solution serious leakage is carried out effective shutoff, easily occurs large-area reinforcement repeatedly, affects the problems such as safety of surrounding environment.Chinese patent (publication No.: CN101914917A, the day for announcing: 2010.12.15) disclose a kind of excavation of subway foundation pit in soft soil area anti-seepage and leak-blocking construction method, it is the construction technology for plugging to serious leakage point, in breakthrough outside, adopt high-pressure rotary-spray technique to reinforce, but the reinforcing body forming due to high-pressure rotary-spray has uncertain, discontinuous feature, cannot guarantee hole to be full of completely, surrounding environment is easily polluted in the construction of the unstable and high-pressure rotary-spray of plugging effect.
The plugging structure of a kind of fast effective environmental protection of needs when the situation of seepage appears in diaphragm wall, carries out shutoff to infiltration point in sum.Given this, for when serious leakage appears in diaphragm wall, can effectively carry out as early as possible shutoff operation, need badly at present invention a kind of plugging effect good, construction operation is fast, has the diaphragm wall serious leakage plugging structure of good technical economic benefit.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of rational in infrastructure, the diaphragm wall serious leakage plugging structure that plugging effect is good, speed of application is fast.
This diaphragm wall serious leakage plugging structure, comprise prefabricated shutoff steel plate, the water conservancy diversion Grouting Pipe being connected with prefabricated shutoff Plate Welding, hydro-expansive rubber and repair layer, at breakthrough place, dig and have circle or square groove, and in diaphragm wall, draw through hole, inject water conservancy diversion Grouting Pipe, water conservancy diversion Grouting Pipe is obliquely installed, by expansion bolt, prefabricated shutoff steel plate is arranged to diaphragm wall inner side, at prefabricated shutoff steel plate periphery outsourcing hydro-expansive rubber, in diaphragm wall outside, be marked with slip casting occluding body with soil layer junction, at prefabricated shutoff steel plate arranged outside repair layer.
As preferably: described water conservancy diversion Grouting Pipe is stretched out diaphragm wall outside 10~25mm, and water conservancy diversion Grouting Pipe is obliquely installed.
As preferably: by expansion bolt, prefabricated shutoff steel plate is arranged to diaphragm wall inner side.
As preferably: connect dismountable valve end after described water conservancy diversion Grouting Pipe, both are threaded.
As preferably: by shutoff spirit, water conservancy diversion Grouting Pipe is set and seals.
The beneficial effects of the utility model are:
(1) water conservancy diversion Grouting Pipe tilts, and during draining, as conduction pipe, during slip casting shutoff, as Grouting Pipe, easy construction, saves man-hour, accelerates shutoff speed.
(2) adopt the prefabricated shutoff steel plate of outsourcing hydro-expansive rubber to be fixed on diaphragm wall inner side, guaranteed the effect of shutoff, also improved the globality of restoring area.
(3) after water conservancy diversion Grouting Pipe, connect dismountable valve end, can shorten the length of water conservancy diversion Grouting Pipe, by it together with prefabricated shutoff Plate Welding, the outer repair layer of steel plate just can cover water conservancy diversion Grouting Pipe, make it just stay in body of wall, do not need to remove water conservancy diversion Grouting Pipe, in the time of can preventing from removing water conservancy diversion Grouting Pipe, destroy occluding body, improve restoring area globality simultaneously.
