Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of Bag Grouting Pile bracing means, at least comprises crutcher 1, stirring slurry can 2, shove pump 3, sprinkling irrigation recorder 4, slip casting steel core pipe 5, nylon cloth bag 6, steel collar 7, steel core pipe bottom tube 8 and Plastic cap 9; Described shove pump 3 is communicated with stirring slurry can 2 by pipeline; Described shove pump 3 connects slip casting steel core pipe 5 by pipeline, and on pipeline, be connected with sprinkling irrigation recorder 4; Described slip casting steel core pipe 5 bottom is connected with nylon cloth bag 6; Described steel core pipe bottom tube 8 is arranged on slip casting steel core pipe 5 bottom, and is connected with slip casting steel core pipe 5.
As further technical scheme of the present utility model: described nylon cloth bag 6 is set in slip casting steel core pipe 5 Basolateral, its top is linked as one by steel collar 7 and slip casting steel core pipe 5; Described Plastic cap 9 is fixed on steel core pipe bottom tube 8 bottom.
As further technical scheme of the present utility model: it is coal dust ash and cement that described crutcher 1 stirs material, and slurries are by water: cement: flyash=1: the match ratio of 0.732: 0.599 is prepared.
The utility model is in use:
(1) slurries of Bag Grouting Pile are by water: cement: flyash=1: the match ratio of 0.732: 0.599 is prepared, viscosity is 30 ~ 35s, density is 1.4 ~ 1.5g/cm, bleeding rate < 3%, uniaxial compressive strength > 2.4MPa (7d in the length of time).Adopt mortar mixer mixing, each stirring is no less than 3min; The good slurries of mixing must not holding time long, slip casting should complete in 1h; For preventing cement paste from emanating, slurries will constantly stir in mortar mixer; Just slowly pour into storage bin hopper, to remove foreign material after mortar mixer filters via 3mm hole sizer until slurries before mud jacking.
(2) slurries injection bag pile forms pile body in outside expansion process, therefore slip casting should be carried out successively immediately following boring; Bag pile slip casting should be followed from bottom to top, section by section the principle of mud jacking.
1. grouting pipe connects
Adopt mortar extrusion pump, be connected with storage bin hopper, Grouting Pipe by 5cm pressure hose, and install electromagnetic flowmeter to measure slurry flow.
2. grouting pressure table is adopted to control grouting pressure
Grouting pressure controls at 0.3 ~ 0.5MPa, and injection speed remains on 10 ~ 12L/min; Grouting pressure is generally 0.3 ~ 0.5MPa, once exceed design pressure, should in time on pull out slip casting core pipe; Should strictly flow rate of grouting be controlled at 10 ~ 12L/min during slip casting, must guard against excessive.
3. slip casting section pipe-pulling speed
Calculate pile body length according to injection slurry amount, start more than adopting board-plugging device after 3.0m to pull out slip casting steel core pipe slowly, pipe-pulling speed controls at 10 ~ 15cm/min; In tube drawing process, if pressure is lower than 0.3MPa, stop tube drawing, when pressure reaches 0.5MPa, lasting 1min is slow tube drawing again.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
