Description
Technical field
A kind of of the invention and a kind of basement process system, and in particular to adjustable terrace reply later period uneven settlement of foundation
Control system.
Background technique
Basement process is mainly used for the field that subsoil is unable to satisfy top-out load requirement for bearing capacity or deformation requirements
Ground, common method have preloading method, Deep Mixing Method, Sand Pile Method etc..Since formation is mostly non-uniform Soft Soil Layer,
When formation condition changes greatly or upper load has change, treated, and terrace still will appear differential settlement, generally use note
Slurry processes carry out ground restoration, but when workshop has come into operation, repair need to carry out indoors, be may require that sometimes in dustfree environment
Middle construction, the technology for repairing use are restricted.Simultaneously after primary reparation, if later period terrace sinks again, need again
Secondary independent carry out repairing construction, influences industrial production.
Summary of the invention
Based on above-mentioned technological deficiency, the present invention provides a kind of terrace settlement treatment method, by pre-buried under structure sheaf
Grouting Pipe is expanded, solid soil volume by the slip casting under terrace using fracture grouting principle, swells terrace, with lifting
Terrace reduces terrace sedimentation, can carry out slip casting at any time when differential settlement occurs for terrace, is lifted terrace, reduces sedimentation, and root
According to the variation of optic foundation settlement detector Observable settlement of foundation, the differential settlement of ground is found in time, carries out ground restoration,
And can construct indoors, meet dustless construction environment, solves the trouble and worry of basement process settlement after construction.
In order to reach above-mentioned technical effect, the technical solution adopted by the present invention is that:
A kind of terrace settlement treatment method, including following processing step:

It is built into slip casting pipe network system, is finally laid with floor structure layer, meanwhile, guarantee to be equipped in the middle part of Grouting Pipe to penetrate and starches hole, and both ends
Nozzle exposes structure sheaf；
S2., monitoring system: mounting foundation settlement monitoring device is set；
S3. it enables slip casting pipe network system: when monitoring that part sedimentation occurs in ground, enabling slip casting pipe network system at this
Grouting Pipe net unit；
S4. slip casting: slurries are pressed into soil layer by the Grouting Pipe of pre-plugged with high-pressure injection pump；
S5. it cleans slip casting pipe network system: rinsing Grouting Pipe with clear water after slip casting, complete terrace settlement treatment.
Further, the Grouting Pipe in the step S1 uses unidirectional grout valve pipe, and Grouting Pipe is laid with using horizontal, slip casting
The both ends of pipe are bent upwards, and one end nozzle is grouting port, and other end nozzle is grout outlet, and by-level position offers multiple groups and penetrates
Hole is starched, slurry hole is penetrated and is wrapped with rubber case.
Further, the length of the Grouting Pipe is 4-6m, and the Grouting Pipe net unit is that several Grouting Pipes are horizontal horizontal
To or longitudinal successively overlap joint connection formed, several Grouting Pipe net units constitute slip casting pipe network system.
Further, the Grouting Pipe in the step S1 is closely affixed with mattress layer, and it is solid that fixing piece is added when there is gap
Fixed, adjacent two Grouting Pipes are fixed in lap-joint using fastener.
Further, the Grouting Pipe uses the plastic tube of internal diameter 40-60mm, bores one group every 33-50cm and penetrates slurry hole.
Further, the burst pressure of the rubber case is 4.5MPa, and the slurry hole of penetrating of Grouting Pipe is diameter 8mm.
Further, the high-pressure injection pump in the step S4 is grouting pump, mortar pump, fine-stone concrete pump or concrete pump, slip casting
Pressure 1-10MPa.
Further, the slurries in the step S4 are that discarded slurry adds filler to form in construction.
Further, the slurries in the step S4 are cement slurry, cement mortar, cement, flyash mud or lime white
Liquid.
Further, the step S5 further includes being extracted out the water in the Grouting Pipe after cleaning using high-pressure pump.
Compared with prior art, the beneficial effects of the present invention are:
1, it is settled using monitoring device real-time monitoring terrace, can find uneven settlement of foundation in time, be handled early.
2, built-in slip casting pipe can prevent later period settlement of foundation progress injecting treatment, can construct, not influence under dustfree environment
Production, reduces the loss that machine is moved and stops production.
3, Grouting Pipe is rinsed with clear water after slip casting, Grouting Pipe repeats slip casting and uses, and solves basement process completion
Occurs the trouble and worry settled again afterwards.
The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
And it can be implemented in accordance with the contents of the specification, and in order to allow above and other objects, features and advantages of the invention can
