Description
Technical field
The present invention relates to the hydrophobic construction method of a kind of waterproof, relate in particular to the hydrophobic construction method of a kind of new waterproof.
Background technology
Along with urban construction constantly develops, the construction of highrise building and super highrise building is more and more, the degree of depth of basement and the number of plies are also in continuous increase, be with the construction works such as underground people's air defense, underground store, underground parking also more and more general, but its basement leakage phenomenon of bringing also increases thereupon, had a strong impact on construction engineering quality, used normally and manage and brought very large inconvenience also to basement.
Due to construction accidentally or the reason such as ground water pressure is large, the building of the basement degree of depth below groundwater table is easy to occur drainage, conventional underground waterproof engineering thinking is to rely mainly on prevention, after occurring leaking, just repair leak stopping, but some basements have been fitted up and have been come into operation, the source leaking is difficult to be found, even if leakage point is repaired, also the very difficult assurance later stage does not leak again, therefore cause the long-term existence of basement infiltration hidden danger, and then shorten the application life of basement and even whole building.
By retrieval, learn the patent of having authorized:
1 application number is: the Chinese patent of CN200720097389.1 discloses " a kind of basement waterproofing drainage structure ", it comprises along the multiple gutters that are filled with cobble in it that arrange on basement surrounding retaining wall inner side and sole plate, the top in each described gutter is provided with drain cover, its bottom is provided with rhone to join mutually and to be provided with drain cover in junction, in adjacent gutter intersection, be provided with catch pit, described catch pit is connected with water pump by gutter.This structure can solve basement leaking problem, and changing passive leak stopping is Active Drainage, guarantees that basement is all the time in dry use state, and solved basement leak stopping in the past not complete can not to carry out next procedure construction not enough simultaneously, accelerated the construction speed of engineering.Measure is not sealed in this patent ground cushion bottom, while having infiltration phenomenon to occur in basement bottom board, can not play certain sealing process, also can make the other materials of indoor backfill not sink, and causes the problem of ground cracking.On the sole plate of this patent, be provided with gutter in addition, if once gutter is stopped up, will cause basement infiltration to leak, and it is also very large to repair difficulty.
