Abstract
A vibroflotation meshed caisson device relates to a seamless impervious wall construction device. The vibroflotation meshed caisson device comprises a pair of identical caissons with rectangular cross sections, a vibrating hammer connecting head is arranged at the upper end of each caisson, a bottom-disjointing caisson tip and spray nozzles are arranged at the lower end of each caisson, support ribs used for supplying water to the spray nozzles are welded on two long edges of each caisson, disconnected guide grooves are arranged on one side of two short edges of each caisson, and a T-shaped guide beam is arranged on the other side of the two short edges of each caisson. When an impervious wall is constructed, the first caisson is sunk into the ground firstly by means of jet flow punching and vibrating soil extrusion, the guide grooves of the second caisson are meshed with the guide beam of the first caisson and sunk into the ground along the first caisson, the first caisson is filled with slurry and pulled out through vibration, the slurry is filled in an underground cavity extruded by the first caisson, the first caisson is sunk into the ground along the second caisson, and the second caisson is filled with the slurry and pulled out through vibration. The process is carried out in cycles so that the seamless impervious wall is formed. By means of vibration and jet flow and the technologies of groove forming through ground breaking and alternate sinking of the two meshed caissons, the construction efficiency of the impervious wall in dense sand soil layers is improved, and intersection and discontinuity of the impervious wall are avoided.
Description
Technical field
The utility model relates to a kind of device that utilizes jet cutting and vibration to squeeze the no seam seepage control wall of the engagement type caisson construction of row's foundation soil.
Background technology
Impervious wall construction is widely used in hydraulic engineering, engineering fields such as urban architecture and refuse landfill antiseep.Various impervious wall construction technology all have its limitation, and the subject matter one of existence is the intersegmental seams such as discontinuous or intersection that often produce of each wall of impervious wall, has a strong impact on construction quality; The 2nd, heavy modulus method resistance is big on closely knit stratum, and settling rate is slow, has a strong impact on speed of application and efficient.
Summary of the invention
In order to solve the problem that present impervious wall construction exists, the utility model provides a kind of and has shaken towards engagement type caisson device, this device can not only be avoided the discontinuous or cross-cutting issue of the intersegmental generation of each wall of impervious wall, improve construction quality, and utilize vibration and jet cutting effect to improve in closely knit stratum caisson sinking speed, improved efficiency of construction.
The technical scheme that the utility model adopted is: this utility model is made up of two identical secondary rectangular cross section casings, the upper end of every auxiliary box body is provided with vibrating hammer connector, Joint for water supply, filling adaptor and filling concrete mouth, the lower end is to take off formula case point and nozzle in the end, casing two long sides are welded with ribs from water to nozzle that send, casing two minor faces one side be T type nose girder, opposite side for can with the discontinuous guide groove of T type nose girder engagement.During the construction impervious wall, utilize the die-cut and vibration of injection stream to squeeze foundation soil, it is underground that the first casing is sunk to, the guide groove of second casing and first casing T type nose girder engagement is then also sunk to underground along the first casing, also vibrated to first casing perfusion slurry material by filling adaptor or filling concrete mouth then and pulled out the underground cavity pocket of extruding when the slurry material just is full of the sinking of first casing; In like manner again the first casing extracted is sunk to underground and vibrate to second casing perfusion slurry material along the second casing and pull out, go round and begin again, just the no seam seepage control wall of formation.
The beneficial effects of the utility model are: grooving that employing is vibrated and spray regime is broken ground, and two secondary caisson be meshing with each other and sink to the underground trenching construction that continues, both enlarged stratum accommodation, improved the efficiency of construction of impervious wall, and avoided the intersection of impervious wall and discontinuous in dense sand soil layer.
