Technical solution of the present utility model is: a kind of slip casing by pressure cluster type miniature steel pipe pilework administering shallow failure, including steel-pipe pile, stake apical cap beam and crossbeam, every two row of described steel-pipe pile or two row composition described above one campsheds, each campshed top is provided with an apical cap beam, steel-pipe pile top in each campshed all embeds an apical cap beam and is connected with stake apical cap beam, is connected by crossbeam between adjacent studs apical cap beam.
Described steel-pipe pile adopts the miniature steel pipe pile of perforate, and stake apical cap beam adopts reinforced beam with crossbeam.
This utility model also includes steel pipe stake holes, and steel pipe stake holes aperture is more than steel-pipe pile external diameter, and steel-pipe pile inserts in steel pipe stake holes, gap between described steel-pipe pile outer wall and steel pipe stake holes hole wall and be filled with cement grout or cement mortar in steel-pipe pile.
Described cement grout and cement mortar technical parameter are as follows:
(1) ratio of mud of cement grout and cement mortar all desirable 0.6 ~ 1.0, the cement-sand ratio of cement mortar is preferably 1.5 ~ 2, and grouting water pH cannot be less than 4;
(2) flow of slip casting desirable (7 ~ 10) L/min, adopts hole-bottom slurry-injection, and grouting pressure dynamically can control according to on-site actual situations.
The beneficial effects of the utility model are: for shallow failure harnessing project, by arranging slip casing by pressure cluster type miniature steel pipe pilework, improve slope stability, it is ensured that the safety of side slope and surrounding enviroment, construction machinery is marched into the arena conveniently, without using large-scale heavy duty equipment, reducing the disturbance to formation and surrounding enviroment, space flexible arrangement in work progress, adaptive capacity to environment is strong, efficiency of construction is high, it is possible to save significantly on the duration.

Detailed description of the invention
Referring to Fig. 1 ~ 7, this utility model includes steel-pipe pile 1, stake apical cap beam 2, crossbeam 3, every two row of described steel-pipe pile 1 or two row composition described above one campsheds, each campshed top is provided with an apical cap beam 2, steel-pipe pile 1 top in each campshed all embeds an apical cap beam 2 and is connected with stake apical cap beam 2, is connected by crossbeam 3 between adjacent studs apical cap beam 2.
Described steel-pipe pile 1 adopts the miniature steel pipe pile of perforate, and stake apical cap beam 2 and crossbeam 3 adopt reinforced beam.
This utility model also includes steel pipe stake holes, and steel pipe stake holes aperture is more than steel-pipe pile external diameter, and steel-pipe pile 1 inserts in steel pipe stake holes, gap between described steel-pipe pile 1 outer wall and steel pipe stake holes hole wall 4 and be filled with cement grout or cement mortar in steel-pipe pile.
Enforcement step of the present utility model is: first carry out the stake holes drilling construction of steel-pipe pile 1, pore-forming aperture is more than the external diameter of steel-pipe pile 1, the sequence of construction of steel-pipe pile 1 should adopt jumping to dig method construction, until after stake holes drilling construction arrives designed elevation, insert the steel-pipe pile 1 of perforate, the strict stake top mark height controlling steel-pipe pile 1, it is ensured that the steel-pipe pile 1 insert depth in stake apical cap beam 2; Then inside steel-pipe pile 1, insert Grouting Pipe, adopt cement grout or cement mortar carry out hole-bottom slurry-injection by the gap between steel-pipe pile 1 outer wall and hole wall 4 and in steel-pipe pile filling closely knit, slip casing by pressure needs in time; Finally according to designing requirement, construction stake apical cap beam 2 and crossbeam 3, ultimately form slip casing by pressure cluster type miniature steel pipe pilework.
The shallow failure harnessing project that this utility model is nervous for surrounding enviroment, construction site is narrow and small, adopts slip casing by pressure cluster type miniature steel pipe pilework to carry out landslide control. Every two row of steel-pipe pile or two row composition described above one are arranged, steel-pipe pile should pass sliding surface, enter the sliding bed certain depth of lower stabilizer, row can flexible arrangement according to actual needs, steel-pipe pile stake top arranges concrete Guan Liang, arrange concrete beam between adjacent two row's steel-pipe pile stake apical cap beams to connect, form the reinforcement system with certain space structure. Wherein gap between steel-pipe pile outer wall and hole wall and to adopt cement grout or cement mortar to carry out slip casing by pressure filling in steel-pipe pile closely knit.
This utility model has the advantage that
