Background technology
At present, in hydraulic engineering, the subterranean continuous imperviousing wall application of low water head widely.During construction, by special equipment, build the groove of one fixed width and the degree of depth according to designing requirement, its length is determined according to designing requirement, and because length is longer, when building impervious material in the trench, groove must be divided into several groove sections, leakage proof wall is built in segmentation.Groove section separates common methods to be had: method 1: point sequence excavation section by section, build body of wall, namely multiple groove section is divided into according to impervious wall design axis by planning to build the impervious wall made, first the impervious wall alternation excavation made will be planned to build, build this groove section impervious wall again, non-box cut section is as spacer body, when having built after the impervious material in groove section reaches some strength, excavate the groove section body of wall as interval again, namely first excavate and build 1,3,5 ... section, excavate again and build 2,4,6 ... section, namely the body of wall of having built can be used as spacer body, and a point sequence completes wall construction like this.Method 2: the continuous channel first building certain length, then locking notch pipe (junction block) is inserted in the trench, and be fixed, impervious material is under water built respectively in the groove section on locking notch pipe both sides, after the impervious material of locking notch pipe both sides groove section reaches some strength, extract locking notch pipe, the body of wall of clear hole after-pouring locking notch pipe part, completes two sections of wall connectings.The segregation method of above groove section all exist complex procedures, speed of application slow, can not work continuously, quality is not easy the shortcomings such as guarantees, especially the connection of continuous wall connector is difficult to process; In addition, easily there is problems such as can not pulling out out or pull off, thus cause quality accident in the locking notch pipe in method 2.
Summary of the invention
The present invention, in order to make up the shortcoming of above construction of diaphragm wall, provides a kind of special-shaped air bag and with the speedy construction method of special-shaped air bag as underground continuous wall connector spacer body.The present invention is achieved through the following technical solutions: a kind of special-shaped air bag for underground continuous wall connector, this special-shaped air bag includes valve, the outer wall of described special-shaped air bag is provided with resistance nail, and described resistance nail is in solid hemispherical, and plum blossom-shaped is arranged in different in nature gasbag ektexine.
A kind of underground continuous wall connector speedy construction method utilizing special-shaped air bag:
One, during construction, special-shaped air bag is placed in respectively the groove of construction plant according to certain distance, utilizes special-shaped air bag to be some groove sections by trench separation;
Two, weighted spherical ball is fallen into the bottom of special-shaped air bag, weighted spherical ball plays counterweight, guiding and positioning action;
Three, make it expand through valve inflation in special-shaped air bag, the special-shaped air bag after expansion embeds in the cell wall in groove by resistance nail;
Four, then respectively impervious material is built to the groove section on special-shaped air bag both sides, after impervious material reaches some strength, to special-shaped air bag deflation, propose special-shaped air bag; Special-shaped air bag cycle applications is constructed in next groove section;
Five, fully rinse the cavity at special-shaped air bag place, build the second stage of impervious material, make each groove section be linked to be as a whole, good fusion is played to two phase impervious materials in the cavity that resistance nail place is stayed.
Six, this operation terminates, and completes follow-up wall construction by that analogy.
In above process, weighted spherical ball has constant weight, and has a certain amount of powdered lubricant to coordinate.
In above process special-shaped air bag arrangement and take out can not be damaged.
Described special-shaped air bag is high-pressure gasbag, resistance to wears, and its diameter is slightly wider than groove width.
The present invention has efficiently construction of underground continuous wall jointing, feature fast, can substantially increase programming.
