Description
Technical field
The utility model is related to injecting treatment fields, more particularly to one kind of basement process is carried out to indoor existing miscellaneous fill
Slip casting pilework.
Background technology
Miscellaneous fill is artificial unordered backfill formation, and foundation bearing capacity is relatively low, generally cannot directly as soil supporting layer, but
In engineering construction, especially when basis uses the strip footing either single layer, multi-storey building or workshop of isolated footing, one
As basement process only is carried out to the miscellaneous fill under basic scope, it is higher that foundation load is such as delivered in bearing capacity under ground using stake
Stratum in, and carry out treatment (about 30cm thickness) as miscellaneous fill is often only simple within the scope of room cubsoil other than basis
Afterwards with regard to the construction of the indoor waterproof of progress or concrete topping, for a long time, although miscellaneous fill overlying doors structure load is not high,
But because miscellaneous fill is less closely knit, porosity is big in soil, does not complete, from consolidating, itself to will produce sedimentation, indoor earth's surface is caused to send out
Raw sedimentation, pre-buried underground utilities indoor at this time may be damaged, and especially the pipelines such as water, heating power once settle change up and down
Shape is damaged leakage, and miscellaneous fill is impregnated and caused the collapsibility banketed by percolating water, and flooring will generate bigger
Sedimentation or differential settlement, the normal use on extreme influence ground within doors, therefore permanent work is both needed to in compartment
The miscellaneous fill of table structural load is handled.
Although there are many method for processing foundation at present, because being located in interior, large scale equipment can not march into the arena construction at all, so just
Method is extremely limited, at present there are mainly two types of interior room cubsoil method for processing foundation：(1) cushion is dug out, that is, digs out miscellaneous fill, is changed
The construction material being filled into, because constructing indoors, big machinery can not pass in and out and construct, can only hand excavation, therefore this
A method is generally adapted the smaller miscellaneous fill of processing thickness, when miscellaneous fill is thicker, such as exceeds 1.0m, then uneconomical.(2) conventional
High-pressure slip-casting method, i.e. vibration sink to slip casting steel pipe, inject cement mortar by Grouting Pipe high pressure (general 3-5 MPa) to reach
Cure the purpose of miscellaneous fill, but because of the inhomogeneities of miscellaneous fill, high-pressure slip-casting slurries flow to no controllability, are as a result exactly miscellaneous
Banketing, it is uneven to reinforce, and miscellaneous fill intensity after slip casting in part improves, intensity does not improve substantially after room cubsoil in part is reinforced,
Slip casting effect is uneven, while uncontrollable grouting serous fluid is seized every opportunity under high pressure, indoor section pipeline such as heating power pipe trench
So that it is can not operate normally etc. filling, causes secondary loss.
Utility model content
Technical problem to be solved in the utility model is in view of the deficiencies of the prior art, to provide a kind of slip casting pilework,
