Injection pipe in single pipe method and double tube method is thinner（Aperture is within 5cm）.It is usually 7 that three tube method, which spray pipe diameter,
~ 9cm, it is complicated, therefore sometimes for the hole of one a diameter of 15cm of pre- subdrilling, be then placed in three pipe inspections and construct.
Cement bin, water tank and Weighing system are specially provided in construction.During conveying cement mortar, high pressure water, compressed air, if
Monitoring device is set, to ensure construction quality.Grout can in time be absorbed with sewage pump in construction, and be transported to place with
Outside.
Single tube spinning-jet：Spraying cement slurries, stake diameter is minimum, and stake diameter is general≤0.6m, it is commonly used in loose, slightly close layer of sand
In, the general ＜ 200kg/m of cement consumption（Indicate that stake is long per m cement consumptions）, normal construction speed is generally in 20cm/min.
Two-tube churning：Spraying cement slurries and air, the general 0.6m ~ 0.8m of stake diameter, in being commonly used in close layer of sand, cement
The general ＜ 300kg/m of dosage, normal construction speed is generally in 10 ~ 20cm/min.
Triple pipe rotary spray：Spraying cement slurries and air and high pressure water, mechanism is to remove cutting soil, cement mortar with high pressure water
Then the soil body after going filling to cut again, the general 1.0m ~ 1.2m of stake diameter can construct, cement consumption generally exists in gravel layer
400kg/m, normal construction speed is generally in 10 ~ 20cm/min
Single tube only has one to manage again, can only high-pressure mortar spraying, expanded diameter is smaller, similar with mixing pile,；It is two-tube to be exactly
High mud jacking and high pressure gas（Gas blows soil soft again with soil stirring), the drilling rod of two-tube churning is double, a pipe whitewashing again, another
Pipe jet again；Three pipes are exactly that the high mud jacking water that adds high pressure is increased and calms the anger, and pile form is by slurries pressure itself in compressed air
It under promotion, is stirred by high -pressure water cutting, compressed air, forms vortex under a subterranean formation, and by the permeability shape on stratum itself
At a complete pile body.
Single tube is less than three pipes less than two-tube in terms of quality.But single tube is less than three pipes less than two-tube in terms of price.Three kinds suitable
What big difference is range be without, and typically economically face considers.Usual two tube method is usually used in muddy
The construction of layer etc., three tube method are usually used in the construction in addition to above-mentioned stratum, and three pipes are generally used for water-stop curtain stake.
Single pipe method, two tube method, the slurries that aperture is emerged do not recycle；Three tube method, it is recyclable according to engineering design requirements
The slurries emerged using aperture.
It has been shown that, the engineering ground-connecting-wall interface are checked and accepted by inspection during high-pressure rotary jet grouting pile and earth excavation and observation
Place does not find leak source, meets design and code requirement, and work progress requires with meeting site construction management and Fujian province-norm chemical industry,
The respectively favorable comment for the side of being taken part in building.
The present invention has substantive distinguishing features and significant technological progress, and of the invention is used as diaphram wall interface external reinforcement
The Construction of High Pressure Jet Grouting Pile method of sealing sealing jumps out diaphram wall wall structure itself, is applied using ripe high-pressure rotary jet grouting pile
Work technique, during ground-connecting-wall interface external reinforcement sealing sealing is constructed using high-pressure rotary jet grouting pile, to ensure pile matter
Amount and water-stagnating effect create advantageous operating condition for follow-up earth excavation operation, during Construction of High Pressure Jet Grouting Pile and follow-up
In earth excavation construction, by project supervision and owner to critical processes have carried out other station, observation is checked and accepted etc. such as positioning, spraying.
Above example is used for illustrative purposes only rather than limitation of the present invention, the technology people in relation to technical field
Member, without departing from the spirit and scope of the present invention, can also make various transformation or variation.Therefore, all equivalent
Technical solution should also belong to scope of the invention, should be limited by each claim.
