Abstract
A new material underground structure leakage stoppage construction technology includes the following steps that firstly, cleaning is performed; secondly, drilling and drainage are performed; thirdly, a grouting guide pipe is installed; fourthly, cracks are sealed; fifthly, grouting is performed, wherein ultra-fine cement slurry materials are adopted for grouting, water leakage is reduced or disappears, then permeable crystallization grouting materials are injected to plug a tiny water seepage channel, and finally epoxy resin grout is injected for reinforcement; sixthly, a nozzle is detached; and seventhly, sealing is performed. Through a traditional leakage stoppage method, only obvious cracks can be plugged. According to the new material underground structure leakage stoppage construction technology, ultra-fine cement slurry is adopted for plugging the tiny cracks, the phenomenon that only the temporary problem is solved and the fundamental problem is not solved is effectively avoided, and the effect of fundamentally suppressing structural crack water leakage is achieved. By means of the method, repeated construction of leakage stoppage operation can be avoided, the effects of saving cost of labor, machines, materials and the like are effectively achieved, and good economic benefits are achieved.
Description
Technical field
The invention belongs to the blocking technology field of subway station or other underground structure shutoff micro-cracks, be specifically related to a kind of new material underground structure blocking constructing process.
Background technology
Current Tianjin Underground station owner body structure completion, there is Seepage in various degree in part-structure; And in ensuing accessory structure work progress, also may run into structural leakage problem.If do not take reliable plugging watertight method in the middle of work progress, may have an impact to the internal construction at station, shortening structure application life, seepage seriously even there will be the phenomenon such as quicksand and piping.Further, in station, percolating water also can bring a series of impact to follow-up operation repeatedly, affects the using function at station, therefore selects rational construction material, carries out plugging watertight construction to subway station, effectively can ensure the construction quality of subway station.
Summary of the invention
The present invention is directed to above-mentioned weak point and a kind of leak-blocking construction method for micro-cracks is provided, utilize the construction technology of micro-cracks in new material shutoff underground structure.
The technical solution used in the present invention is:
A kind of new material underground structure blocking constructing process, comprises the following steps:
(1) clear up: detailed inspection, analysis leakage scenarios, clean out the region needing construction, cut concrete surface precipitate, guarantee surface clean;
(2) trepanation and drainage: use electric drill to hole along the place of leaking, bit diameter is 25mm, bore angle≤45 °, drilling depth, through crack, makes current discharge from boring;
(3) grouting pipe is installed: in the hole of having bored, conduit is installed, installs firmly;
(4) joint seal: the space water between surrounding catheter and boring does not leak shutoff, make to leak along conduit and flow out, surrounding catheter is water-tight;
(5) slip casting: grouting sequence is from one end, and single hole carries out one by one continuously; Grouting pressure is 0.5 ~ 1.0MPa, first adopts the slip casting of superfine cement pulp material, and making to leak reduces or disappear, and then injects the trickle penetrating passage of penetrant crystalline injecting paste material slurries shutoff, the reinforcement of last injection ring epoxy resins slurries;
(6) tear mouth open: slip casting is complete, confirm not leak the grouting nozzle that can remove or knock out and expose; Clean out the slurries that the spill and leakage that solidified goes out;
(7) seal: repairing, the sealing process of carrying out grouting port with leak stopping spirit.
Described superfine cement slurry for raw material, is that 0.8:1 ~ 1:1 batching make slurries according to water/binder ratio with middle rock superfine cement.
Described penetrant crystalline slip casting, with CCCW type penetrant crystalline cement, makes slurries according to water/binder ratio 0.6:1 ~ 1:1 batching.
Described epoxy resin slurries are with epoxy resin, 731 epoxy resin and 501 epoxide resin reactive diluents for batching, and proportional quantity is respectively 100; 25 ~ 35; 10 ~ 20.
Beneficial effect of the present invention: traditional blocking method can only the obvious crack of shutoff, the present invention is with superfine cement slurries shutoff micro-cracks, effectively avoid traditional method for blocking " to cure the symptoms, not the disease ", the effect fundamentally suppressing structural cracks percolating water can be played.This method can avoid plugging operations to repeat construction, effectively serves the expenses such as saving is artificial, machinery, material, has good economic benefit.
Detailed description of the invention
Tianjin Underground No. 6 line northern stations utilize new material to underground structure blocking constructing process, comprise the following steps:
