Description
Technical field
The utility model is related to municipal administration, technical field of buildings, and in particular to a kind of certainly into the pull-type steel sheet pile supporting of churning anchor
Structure.
Background technology
In the pipe trench of Municipal engineering, piping lane foundation trench excavation project, pipe trench is solved, piping lane foundation trench excavation prevents from caving in
Conventional scheme mainly have：1, slope is excavated in the case of and surrounding enviroment conditions permit preferable in formation stability；2, weak soil
Formation condition is generally inserted into Larsen steel sheet pile using vibrations and protects the both sides soil body, and both sides are collapsed after avoiding groove earth excavation
Side, when foundation trench is shallower, steel sheet pile can be protected with cantilever, when depth is deeper, need to set bracing members between two rows of steel sheet piles
Supporting, according to the intensification of depth, multiple tracks is arrived in support setting one, when inner support is arranged, gives follow-up earth excavation, down tube or piping lane
Civil construction brings inconvenience, not only affects the duration, but also increase cost.
Through looking into, there are one entitled for associated patented technology《Deep foundation ditch steel plate pile adds cable bolting system construction method》
（Application publication number is CN102817364A）Patent of invention, drawn using the outside anchor of anchor cable, instead of inner support method.According to ground
Engineering theory and practical experience, this method for being that there is no problem for the application of physical and mechanical property preferable rock-soil layer below groove,
But it is big for weak soil thickness, for the smaller soft soil layer of adhesion strength, it can be answered caused by anchorage cable anchoring power is low, shear resistance is weak
With and it is dangerous, be poorly suitable for the deep stratum of weak soil, for soft clay area, deeper situation or commonplace
's.Another aspect anchor cable needs to wait for very long anchoring body setting time（General 15 days or more）Ability tensioning, construction period is very
It is long.
Associated one entitled《Reinforce anchor beam》（Authorization Notice No. CN202850514U）Utility model patent, be used for
To the device that existing building structure is reinforced, vertical structure is existing building, and anchoring body is also disposed in fabric structure,
Casing connection is needed, which is not the method for solving the problems, such as Soft Soil Layer deep foundation pit support.
Invention content
In view of the above technical problems, the utility model provides a kind of certainly into the pull-type steel sheet pile supporting construction of churning anchor, including
Steel sheet pile and from mounting hole into anchor pole, is provided on the steel sheet pile, described from being passed through into anchor pole, mounting hole is oblique to squeeze into side wall, institute
It states and steel waist rail is installed at the mounting hole of steel sheet pile, steel boots are installed on the steel waist rail, the external end head from into anchor pole is set
There are high-strength bolt, the high-strength bolt to pass through steel waist rail and steel boots and be fixed on steel boots by nut.
Further, described from being tubular structure into anchor rod body, flight, the anchor pole tube body are installed on the outside of the body of rod
Lower end be provided with nozzle, it is described to be equipped with drill bit from into anchor pole inner end tail.
Further, it is equipped with bearing plate between the steel sheet pile and steel boots and between steel boots and nut.
Further, steel corbel is installed, the steel corbel is fixed on the lower part of steel waist rail on the steel sheet pile.
Further, the steel waist rail is that Two bors d's oeuveres shaped steel is welded together by batten plate, and middle part is welded with steel ribs.
Further, the high-strength bolt is connect by casing with anchor pole.
Further, the nozzle is conical nozzle or unidirectional Anti-clogging spray nozzle.
For the deep basal pit under the conditions of thick big soft soil layer, the utility model from into jet grouting anchor rod complex soil nailing wall supporting
Structure has apparent advantage, on the one hand, eliminates inner support, avoids inner support to earth excavation and subsequent pipeline construction band
The inconvenience come, is greatly saved duration and cost；On the other hand for thick big soft soil layer, jet grouting anchor rod anchor force is big, shearing resistance
Intensity is strong, and supporting construction stability is high, securely and reliably；Third, the structure do not need prestressed stretch-draw, and nut is only needed to tighten lock
Fixed, speed of application is greatly speeded up, meanwhile, noiseless, mud-less pollution of constructing, the feature of environmental protection is good.
