Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model, after having read the utility model, art technology
Personnel fall within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.
The utility model provides a kind of precast pile head water proof structure, and water proof structure main body 1 is square structure, waterproof structure
Make 1 lower part of main body be prefabricated pile 2 pile crown 21, water proof structure main body 1 from bottom to top successively include polyurethane water-proof paint layer 11,
Concrete cushion 12, cement based penetration crystallization type water proofing paint layer 13, MBP coil waterproof layer 14 and concrete floor layer 15；In advance
Reinforcing bar 3 is equipped in the pile body 22 of stake 2 processed, and reinforcing bar 3 stretches out 21 top of pile crown of prefabricated pile 2, and stretches out 21 top section of pile crown
3 root of reinforcing bar be equipped with water expandable waterstop 4.
The construction technology of above-mentioned precast pile head water proof structure, comprising the following steps:
Step 1: the top of pile crown 21 of prefabricated pile 2 and side are cleaned out, and substantially smooth, without obvious protruding parts,
Expose the one week polyurethane water-proof brushed with a thickness of 3mm in side at bed course position (expose bed course position and be not less than 50mm) in pile crown
Coating；
Step 2: 3 root of reinforcing bar for stretching out 21 top of pile crown of prefabricated pile 2 being installed by water expandable waterstop 4, this position steel
Muscle 3 is the reinforcing bar 3 in 2 pile body 22 of prefabricated pile with sole plate anchoring, and length is not less than 45 times of 3 diameter of reinforcing bar, and not small
In 1m, water expandable waterstop 4, which has, delays swollen performance, and the expansion rate of 7d is not more than the 60% of final expansion rate, final expansion
Rate is greater than 220%；
Step 3: using the smooth concrete cushion 12 for pouring 100mm thickness of C15 concrete；
Step 4: in 21 top surface of pile crown and side exposed section brushing cement based penetration crystallization type water proofing paint layer 13, and brushing
It extends on concrete cushion 12 at 250mm；
Step 5: the good MBP installation of membrane baseline of bullet on concrete cushion 12, paving MBP coiled material, at any time pay attention to and benchmark
