Green anti-seepage material for lock catch steel pipe pile and preparation method of green anti-seepage material
The invention discloses a lock catch steel pipe pile green anti-seepage material and a preparation method thereof.The lock catch steel pipe pile green anti-seepage material is prepared from, by mass, coarse sand, saw dust, bentonite and polypropylene fibers in the volume ratio of 4: 3: 2: 1 in a cofferdam, and cement, medium-coarse sand, clay and water in the non-leakage volume ratio of 4: 3: 2: 5 outside the cofferdam; uniformly stirring and mixing coarse sand, saw dust, bentonite and polypropylene fibers in the cofferdam according to the volume ratio of 4: 3: 2: 1, and finally adding a proper amount of distilled water and stirring until the materials are just bonded; uniformly stirring and mixing cement, medium-coarse sand, clay and water in a non-leakage volume ratio of 4: 3: 2: 5 outside the cofferdam, finally adding a proper amount of distilled water, stirring until the materials are just bonded, and carrying out polymerization reaction at the temperature of 10-30 DEG C; the anti-seepage material is excellent in mechanical property, good in dry shrinkage, low in anti-seepage coefficient, good in erosion resistance, simple in construction process, excellent in erosion resistance and periodic water pressure resistance, and extremely wide in application prospect in cofferdam anti-seepage engineering in large water accumulation.
本发明公开了一种锁扣钢管桩绿色防渗材料及其制备方法，包括以下质量份的组成：围堰内为粗砂、锯末、膨润土及聚丙烯纤维体积比4：3：2：1，围堰外为水泥、中粗砂、黏土及水不漏体积比4：3：2：5，围堰内按照粗砂、锯末、膨润土及聚丙烯纤维体积比4：3：2：1进行均匀搅拌混合，最后加入适量的蒸馏水搅拌至刚好粘合；围堰外按照水泥、中粗砂、黏土、水不漏体积比4：3：2：5，进行均匀搅拌混合，最后加入适量的蒸馏水搅拌至刚好粘合，10℃‑30℃温度下进行聚合反应。该防渗材料力学性能优良，干缩性好，抗渗系数低，抗侵蚀性能好，施工工艺简单，抗侵蚀、抗周期水压优异，在大体积水中围堰防渗工程中有着极为广阔的应用前景。
