Along with the rise of urban skyscraper and the raising of building density, the occasion that adopts deep foundation bank protection soldier pile to keep off soil, sealing gets more and more.Traditional way is to adopt a large amount of steel concrete to make soil-baffling structures such as gravity, cantilevered, its shortcoming is that material usage is unreasonable, and the duration is slower, and cost is higher, because of pattern foundation pit supporting structure generally belongs to occasional nature, spend a large amount of funds and can cause unnecessary waste.As the stake of cement mix, its slurries by the Grouting Pipe ejection mix the soil body and slurries on the spot, make undisturbed soil improvement the becoming cement-soil that certain intensity is arranged, be widely used in ground stabilization, foundation ditch sealing, retaining soil etc., but because the shear strength of this cement mix stake is lower, it is used for retaining wall separately is unable to do what one wishes, often can only be used and forms water-stop curtain with manually digging hole concrete pile, boring concrete pile etc.
The object of the present invention is to provide a kind of manufacturing process of retaining wall, the cost that this method can be lower forms the retaining wall with higher shearing resistance, flexural strength.
In order to realize the purpose of the invention described above, the present invention realizes that by the manufacturing process of following retaining wall this method comprises the steps:
A) substantially vertically adopt cement mix method to form the cement mix stake of a plurality of layouts in a row;
B) along this rigid rib is being set vertically near the outer side edges of the front side of the vertical cement mix stake in above-mentioned basic edge;
C) vertical cement mix stake back a plurality of in a row forms a plurality of earth anchors on above-mentioned basic edge.
Be preferably in the above-mentioned method, the stake of above-mentioned cement mix is to adopt mechanical slip casting paddling process, high-pressure rotary spraying method or compaction grouting method to form, the coupling beam of the top of these cement mix stakes by along continuous straight runs connects, and the mutual bracing of along continuous straight runs is together in its length range for the adjacent cement mix stake among every row.
Be preferably in the above-mentioned method along continuous straight runs or the oblique rigid rib that is provided with.
Be preferably in the above-mentioned method, this muscle is near the outer side edges of the vertical cement mix stake in the basic edge that forms according to many rows.
Be preferably in the above-mentioned method, this muscle passes the inside according to the vertical cement mix stake in the basic edge of many rows' formation.
Be preferably in the above-mentioned method, the front side along continuous straight runs of vertical cement mix stake is provided with many horizontal rows to waist rail on above-mentioned basic edge, and the presstressed reinforcing steel top in the above-mentioned earth anchor is anchored on this horizontal waist rail.
Be preferably in the above-mentioned method, earth anchor is arranged along oblique formation in the vertical cement mix stake back a plurality of in a row on above-mentioned basic edge more, and every row's earth anchor has a plurality of earth anchors.
Be preferably in the above-mentioned method, the front side along continuous straight runs of vertical cement mix stake is provided with many horizontal rows to waist rail on above-mentioned basic edge, and above-mentioned along continuous straight runs or oblique top to the rigid rib that is provided with are connected with this horizontal waist rail.
Be preferably in the above-mentioned method, above-mentioned rigid rib adopts hard bamboo reinforcement, wooden muscle, metal foil, piling bar, reinforcing bar.
Be preferably in the above-mentioned method, above-mentioned rigid rib is that method is squeezed in the employing hammering, static pressure is squeezed into method, inserted by rolling drilling and forming hole method.
Be preferably in the above-mentioned method, a plurality of in a row cement mix stake back vertical on above-mentioned basic edge forms a plurality of soil nailings, and these soil nailings are connected with above-mentioned horizontal waist rail.
The advantage of the manufacturing process of retaining wall of the present invention is to form shearing resistance, the higher retaining wall of flexural strength, because rigid rib is arranged at the lateral surface of cement mix stake, and be not arranged at the inside of mix stake, it is not bonding with the material of body of a pile of mix stake, be easy to like this after construction finishes, this rigid rib be extracted out or disassembled and reuses, promptly be used for later engineering, adopt the stake of cement mix in addition but not concrete pile, thereby the construction cost as provisional retaining wall is reduced greatly.
Below in conjunction with the mode of accompanying drawing the present invention is specifically described with embodiment.
