Description

Lid refitting puts and has the consolidation grouting system of lid weight
Technical field
The utility model is related to consolidation grouting technical fields, and in particular to a kind of consolidation grouting for covering refitting and putting and having lid weight System has detachable, knockdown lid weight, in the dam foundation treatment of hydraulic and hydroelectric engineering, for the exposed rock mass excavated out The consolidation grouting of lid weight is provided with, and before structural concrete pours, it can be to being protected and being mitigated rock by rock mass surface is filled Body relaxes.
Background technology
Consolidation grouting is widely adopted on the physical and mechanical property for improving developmental joint fissure or fragmented rock body, especially The dam foundation treatment of hydraulic and hydroelectric engineering.Consolidation grouting can be divided into have lid again grouting and uncovered be in the milk again.
Uncovered is in the milk also known as naked rock grouting again, must use relatively low grouting pressure to prevent rock mass from occurring lifting destruction.Lid Weight consolidation grouting can apply higher grouting pressure, and grouting effect is good, therefore in the case that can selectively, ordinary priority Using lid weight consolidation grouting.
For the consolidation grouting of the prior art for having lid weight usually there are two types of mode, reserved protective layer can be used in first way Rock mass as by fill rock mass lid weight, excavate protective layer again before pouring structure concrete, in this case due to after grouting again Blasting Excavation is carried out, disturbance and damage can be generated, and the phase is poured in structural concrete to having filled rock mass, concreting is with protecting Sheath excavation can form construction interference.
The second way for covering the consolidation grouting of weight is after pouring structure concrete, using structural concrete as lid Weight, in this case, first, base surface must excavate completion in advance, can be shelved, there are bad for a long time before structural concrete pours Change risk, second is that must bury grout pipe in structural concrete, pipeline arrangement can excessively have an impact structure, third, basis is opened Dig, structural concrete pours and is interfered with each other with grouting construction larger, construction organization difficulty is big, and the straight line duration is longer.
Therefore, exposed for a long time in base surface, multi-process is constructed, in the case of duration anxiety, after comprehensive weigh, It often has to give up lid weight consolidation grouting, using the relatively poor naked rock consolidation grouting of grouting effect.
Utility model content
Based on this, it is necessary to provide a kind of lid refitting and put, have detachable, knockdown lid weight, lid refitting is put should In consolidation grouting system, during to basement rock cementing operations, lid weight by filling rock mass is used as without reserving protective layer rock mass, it can Before structural concrete pours, to being protected by rock mass surface is filled, working procedure is simple, and the construction time is short.
A kind of lid refitting is put, including being placed on basement rock to the counter-force component of basement rock offer extruding force and being erected at base On rock and for counter-force component to be coordinated to provide the counter-force girder steel squeezed;Counter-force component includes elastic press, guide pipe and counter-force spiral shell It is female;Elastic press is arranged on basement rock to compress basement rock;Counter-force girder steel is equipped with perforation, and elastic press is equipped with through-hole, leads Perforation is penetrated to one end of pipe, the other end of guide pipe penetrates through-hole, and in the axial direction of guide pipe, guide pipe being capable of relative resilient Briquetting is slided with counter-force girder steel, and the pressing plate for compressing elastic press is additionally provided on guide pipe;Counter-force nut is threadedly coupled with guide pipe And with the bottom surface of counter-force girder steel against.
Further, guide pipe is divided into upper pipeline section and the lower tube section being connect with upper pipeline section by the pressing plate, and upper pipeline section penetrates It perforates and is equipped with the external screw thread being connect with counter-force nut thread, lower tube section penetrates through-hole.
Further, the both ends of the counter-force girder steel, which are respectively perpendicular, is vertically provided with anchor pole, and anchor pole is used to be inserted into basement rock By counter-force steel girder erection in the top of basement rock.
Further, the anchor pole and counter-force girder steel are detachably connected.
Further, the counter-force component further includes the backing plate being folded between pressing plate and elastic press.
Further, the quantity of the counter-force component is multiple, and multiple counter-force components prolong along the length of counter-force girder steel Direction is stretched to arrange successively.
Further, between the elastic press of two neighboring counter-force component there is gap, elastic press is compressed in guide pipe Afterwards, the deformation of elastic press is by gap-closing.
The utility model also provides a kind of consolidation grouting system for having lid weight, is reset including provisions for grouting and above-mentioned lid It puts, the provisions for grouting includes the grouting drilling machine being mounted on counter-force girder steel, and the drilling rod for the drilling machine that is in the milk passes through guide pipe and basement rock Contact.
