Abstract

The application is claimed a kind of glass wool cloth mounting method mending concrete sluice plate crack.When crack occurs in sluice plate, the lighter will cause the infiltration of sluice, leak, and infiltration, water leakage increase when serious, when there is piping, will jeopardize the safety of sluice.Therefore, it is to ensure the normal operation of sluice and safely, it is necessary to a kind of preferable crack repairing method of relatively simple and effect.Before repairing mixed mud sluice plate crack with glass wool cloth mounting method, by the concrete dabbing of soleplate crack both sides, width is 300mm or so, and depth is 10~20mm, exposes the new face of concrete, and is rinsed well, then is dried with infrared lamp.Then the epoxy cement slurry that will be modulated fills crack, with the floating dabbing position of trowel.Uniform one layer of epoxy base fluid of brush on sticking veneer is pasted before glass wool cloth, is sticked cutting out in advance and having rolled up the glass wool cloth on paper web, then floating with brush.Then the brush epoxy base fluid on glass wool cloth, pastes the second layer and third layer in the same way.The glass wool cloth on upper strata should be than next slice width 20mm.

Description

Glass wool cloth mounting method mending concrete sluice plate crack

1. art

The present invention relates to a kind of concrete sluice floor crack repairing method, the lighter will cause infiltration, leak when especially crack occurs in concrete water gate floor, normal operation and the safety of sluice will be had influence on when serious, mending concrete sluice plate crack is extremely important to the normal operation and safety for ensureing sluice.

2. background technology

Sluice is widely used in field irrigation, discharge conduit, urban drainage pipe duct, the control of river water level and flow；The diversion of irrigation canal and urban water supply engineering water source；Flood control works；Many aspects such as the gear tide of coastal river course and channel.If crack occurs in concrete water gate floor, the lighter will cause the infiltration of sluice, drainage, particularly when sluice water levels of upstream and downstream difference is larger, will roll up infiltration, leak, will have influence on the normal of sluice and uses；Infiltration, leak are also possible to be pulled away the mud particles of sluice plate bottom, form piping, injure the safety of sluice.Therefore, it is the normal operation of guarantee sluice and safety, it is necessary to be repaired to concrete water pocket floor plank split when crack occurs in concrete water gate floor.Glass wool cloth mounting method mending concrete sluice plate crack is a kind of preferable method of relatively simple and effect.

3. the content of the invention

When crack occurs in concrete water gate floor, the lighter will cause the infiltration of sluice, leak, and infiltration, water leakage increase when serious, when there is piping, will jeopardize the safety of sluice.Therefore, when crack occurs in concrete water gate floor, to ensure the normal operation of sluice with safety, it is necessary to a kind of preferable crack repairing method of relatively simple and effect.

Before glass wool cloth mounting method mending concrete sluice plate crack, by the concrete dabbing of soleplate crack (3) both sides, expose the new face of concrete, then epoxy cement slurry is filled into crack (3), paste the preceding one layer of epoxy base fluid (2) of uniform brush on sticking veneer of glass wool cloth (1), the glass wool cloth (1) cut out in advance is sticked, it is floating with brush, glass wool cloth is combined closely with concrete surface.Then the brush epoxy base fluid (2) on glass wool cloth (1), pastes the second layer and third layer in the same way.Refer to Figure of description.

The beneficial effects of the invention are as follows with relatively simple method mending concrete sluice plate crack, the crack infiltration of elimination concrete water gate floor, drainage.

4. illustrate

Fig. 1 glass wool cloths paste figure, below in conjunction with the accompanying drawings 1 and embodiment the present invention is further described.1. glass wool cloth in Fig. 1,2. epoxy base fluid, 3. concrete water pocket floor plank split.

5. specific embodiment

Before repairing mixed mud sluice plate crack with glass wool cloth mounting method, by the concrete dabbing of soleplate crack (3) both sides, width is 300mm or so, and depth is 10~20mm, exposes the new face of concrete, and is rinsed well, then is dried with infrared lamp.Then epoxy cement slurry (formula is shown in Table 1) that will be modulated fills crack (3), with the floating dabbing position of trowel.Paste the preceding one layer of epoxy base fluid (2) (formula is shown in Table 1) of uniform brush on sticking veneer of glass wool cloth (1), sticked cutting out in advance and having rolled up the glass wool cloth on paper web (1), it is floating with brush again, glass wool cloth is combined closely with concrete surface.Then the brush epoxy base fluid (2) on glass wool cloth (1), pastes the second layer and third layer in the same way.The glass wool cloth on upper strata should be than next slice width 20mm.

The epoxy adhesive material formula table of table 1 (weight ratio)

Claims (1)

1. a kind of glass wool cloth mounting method mending concrete sluice plate crack, the concrete dabbing of soleplate crack (3) both sides is revealed Go out the new face of concrete, epoxy cement slurry is then filled into crack (3), paste one layer of ring of brush uniform on sticking veneer before glass wool cloth (1) Epoxide liquid (2), sticks the glass wool cloth (1) cut out in advance, then the brush epoxy base fluid (2) on glass wool cloth (1), by same Method pastes the second layer and third layer.
