Specific embodiment
With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate.It should be understood that following specific embodiment parties
Formula is merely to illustrate the utility model rather than limitation the scope of the utility model.
Fig. 1 is the structural schematic diagram of the utility model, in conjunction with attached drawing as it can be seen that this reinforced cement-soil pile anchor support, including is hung down
The top cross of straight anchoring pile 1 and oblique anchoring pile 4, the vertical anchoring pile 1 and oblique anchoring pile 4, which contacts, to be fixed, the vertical anchoring pile 1 and oblique anchor
The top of stake 4 is provided with capping beam 3, and the capping beam 3 is flushed with ground.The utility model structure passes through vertical anchoring pile and oblique anchor
Stake contacts supporting in top cross, and stable structure has good anti-pressure ability.
The vertical anchoring pile includes the vertical column of concrete, and the axial centre of the vertical column of concrete, which runs through, steel strand wires 2,
The top of the steel strand wires 2 is stretched out from the vertical column of concrete, and the oblique anchoring pile includes concrete tilt stake, the concrete tilt
The axial centre of stake through there is steel strand wires 2, stretch out from concrete tilt column by the top of the steel strand wires 2.By perpendicular in concrete
It is inserted into steel strand wires 2 in right cylinder or concrete tilt column, improves its strength character, it is ensured that structure safety and firmness.
The construction method of the vertical anchoring pile supporting of reinforced cement earth, comprising the following steps:
(1) it positions: opening dynamic triaxial blender and move on to finger fixed pile, centering, stake position deviations are no more than 5cm.Stake position is inclined
For difference generally no more than 2.0cm, agitating shaft perpendicularity deviation is no more than 1.0%.
(2) slurry configurations: the 1. strict control ratio of mud, match ratio are 1.5~2；2. cement slurry must sufficiently mix uniformly；
3. preferably using ordinary portland cement P32.5 to improve soil cement intensity performance.
(3) it send slurry: by the cement slurry prepared after being sieved through filter, pouring into slurry bucket, start slurry pump, slurries are sent to stirring
Head send the operating pressure of the grouting pump of sizing process to should be greater than 2.8MPa for injection.
(4) it stirs: preferably selecting the whipped form based on helical blade type in sandy soil, mixing speed presses top gear 35r/
Min is controlled by 16 r/min of low or first gear.
