And moreover, the process causes no pollution to the environment.
Description
Technical field
The invention belongs to concrete strengthening field of engineering technology, particularly the shutoff reinforcement means of distress in concrete.
Background technology
At present, concrete extensive use in various engineering construction, especially widely applies in fields such as bridge construction, engineering foundation, road surface sclerosis.While offering convenience to construction, due to some factors such as construction quality, natural external force, easily cause concrete to produce crack, in crack, infiltrate ponding, not only greatly reduce concrete intensity and effect, and long-term lasting infiltration causes to concrete the damage that can not save; If do not reinforced the timely shutoff of distress in concrete, develop as one pleases, very easily cause danger, irremediable loss is caused to engineering safety, personal safety as well as the property safety.
Current market is based on shutoff to the processing method of distress in concrete substantially, has just sealed crack from the teeth outwards, but do not had any Essential Action for concrete reinforcing, and method for blocking technique is simple, effect is bad produces crack very easily again.How processing distress in concrete is comparatively stubborn problem in engineering construction.
Summary of the invention
In order to overcome the above problems, the present invention be a kind of can the construction technique in firm blocking concrete crack.
This chemical grouting shutoff reinforced concrete crack construction technique comprises the following steps.
The first step, opens the wide 20mm in top along distress in concrete, is deep to the V-type groove of few 20mm.
Second step, rinses V-type groove.The giant of 80KG is adopted to be rinsed well by the foreign material such as the sand grains in V-type groove, floating dust.
3rd step, shutoff V-type groove.First adopt German KOSTERKD2 uniform application V-type groove, to smear after German KOSTERKD2 uniform application Germany KOSTERNBI between 10 minutes-20 minutes, then with German KOSTERKB-Pur, V-type groove is carried out shutoff and fill and lead up.When using German KOSTERKB-Pur, German KOSTERKB-Pur is divided into KOSTERKB(A) component and KOSTERPur(B) component, and by (A): the proportioning of (B)=1:1 is prepared burden; The liquid material prepared fully is stirred, until be best when liquid material surface produces a little foam; Then the liquid material of mixing is poured into V-type groove, at V-type groove upper surface uniform application Germany KOSTERKD2 again after 2 hours.
4th step, bores injected hole.Adopt the drill bit of long 35cm along crack upper and lower both sides respectively with level interval for 30 ~ 40cm, injected hole is 15cm ~ 18cm perpendicular to crack distance, drill bit and concrete wall surface angle oblique upper at 45 ° and tiltedly lower drill with ferrule injected hole, bore injected hole depth requirements and reach 24cm ~ 28cm.The injected hole on upper and lower both sides " plum blossom " type of will hoping for success is arranged.
5th step, installs slip casting head.By slip casting head with rubber one end insert the 4th step bore in injected hole adopt special tool by head rotation tighten.
6th step, slip casting.According to the 3rd step when V-type groove carries out starting successively to each injected hole slip casting after shutoff fills and leads up interval 12 hours ~ 24 hours by the German KOSTERKB-Pur in crack.Injecting paste material is German KOSTERKB-Pur, and German KOSTERKB-Pur is divided into KOSTERKB(A) component and KOSTERPur(B) component, and by (A): the proportioning of (B)=1:1 is prepared burden; The liquid material prepared fully is stirred, until be best when liquid material surface produces a little foam; Then pour the liquid material of mixing into slurry filling machine hopper, the Grouting Pipe of slurry filling machine is connected on mounted head and starts slip casting.When having a little liquid material or water from once stopping when closing on and flow out in injected hole injecting in slip casting process, then start the slip casting of next injected hole; Grouting pressure is 0.3MPa ~ 0.5MPa.
7th step, gets head.Slip casting takes out head after completing 12h, slurries in injected hole are removed clean after with German KOSTERKD2 by closely knit for injected hole shutoff and floating.
Adopt this grouting process easy, easy to operate, crack shutoff closed seamless gap, endures hardships lastingly, not easily crack again.Respond well for blocking concrete crack, concrete surface bone dry, leakproof, without moistening phenomenon.Fracture faces shutoff, modified coatings thickness are even, without leak brush, without show-through, without peeling, hollowing, seminess.And this process environmentally safe.

Detailed description of the invention
1-6 with reference to the accompanying drawings, is described in further detail the present invention in conjunction with detailed description of the invention.
This chemical grouting shutoff reinforced concrete crack construction technique comprises the following steps.
The first step, opens the wide 20mm in top along the crack (1) on concrete (2), is deep to the V-type groove (3) of few 20mm.
Second step, rinses V-type groove (3).The giant of 80KG is adopted to be rinsed well by the foreign material such as sand grains, floating dust in V-type groove (3).
3rd step, shutoff V-type groove (3).As accompanying drawing 4, first German KOSTERKD2(4 is adopted) uniform application V-type groove 3, smear German KOSTERKD2(4) uniform application Germany KOSTERNBI(5 between latter 10 minutes-20 minutes), then use German KOSTERKB-Pur(6) V-type groove (3) is carried out shutoff fill and lead up.Use German KOSTERKB-Pur(6) time, by German KOSTERKB-Pur(6) be divided into KOSTERKB(A) component and KOSTERPur(B) component (note: this German KOSTERKB-Pur material is containing KB, Pur bi-material, and separately pack), and by (A): the proportioning of (B)=1:1 is prepared burden; The liquid material prepared fully is stirred, until be best when liquid material surface produces a little foam; Then the liquid material of mixing is poured into V-type groove (3), at V-type groove (3) upper surface uniform application Germany KOSTERKD2(4 again after 2 hours).
4th step, bores injected hole (7).As accompanying drawing 5 and accompanying drawing 6, adopt the drill bit of long 35cm (8) along crack upper and lower both sides respectively with level interval for 30 ~ 40cm, injected hole (7) is 15cm ~ 18cm perpendicular to crack (1) distance, drill bit (8) and angle oblique upper at 45 °, concrete (2) face and oblique lower drill with ferrule injected hole (7), bore injected hole (7) depth requirements and reach 24cm ~ 28cm.The injected hole (7) on upper and lower both sides " plum blossom " type of will hoping for success is arranged.
5th step, installs slip casting head.Special tool is adopted head rotation to be tightened with in one end insertion the 4th injected hole that step is bored (7) of rubber slip casting head.
6th step, slip casting.According to the 3rd step as the German KOSTERKB-Pur(6 in crack) V-type groove (3) is carried out starting successively to each injected hole (7) slip casting after shutoff fills and leads up interval 12 hours ~ 24 hours.Injecting paste material is German KOSTERKB-Pur(6), by German KOSTERKB-Pur(6) be divided into KOSTERKB(A) component and KOSTERPur(B) component, and by (A): the proportioning of (B)=1:1 is prepared burden; The liquid material prepared fully is stirred, until be best when liquid material surface produces a little foam; Then pour the liquid material of mixing into slurry filling machine hopper, the Grouting Pipe of slurry filling machine is connected on mounted head and starts slip casting.When having a little liquid material or water from once stopping when closing on and flow out in injected hole (7) injecting in slip casting process, then start the slip casting of next injected hole; Grouting pressure is 0.3MPa ~ 0.5MPa.
7th step, gets head.Slip casting takes out head after completing 12 hours, is removed by injected hole (7) interior slurries totally and uses German KOSTERKD2(4) by closely knit and floating for injected hole (7) shutoff.
Adopt this grouting process easy, easy to operate, crack shutoff closed seamless gap, endures hardships lastingly, not easily crack again.Respond well for blocking concrete crack, concrete surface bone dry, leakproof, without moistening phenomenon.Fracture faces shutoff, modified coatings thickness are even, without leak brush, without show-through, without peeling, hollowing, seminess.And this process environmentally safe.Be suitable for the crack treatment of the concrete structures such as bridge, house, hard surface.
