Description
Technical field
The utility model relates to ground and basic engineering construction technical field more particularly to it is a kind of control soil deformation it is more
Secondary grouting device.
Background technique
With the fast development of Chinese society economy, Modernized City Construction progress is constantly accelerated, and large-scale synthesis is multi-functional
Groups of building continue to bring out, and infrastructure construction is also being gradually improved.In Excavation Process, the Unloading Effect of the adjacent side soil body is led
Foundation pit enclosure structure is caused to generate corresponding deformation, so as to cause adjacent building basis or hole outer tunnel etc. as the soil body generates together
Corresponding displacement deformation.For example, existing operation tactics are mostly the shield tunnel that precast concrete section of jurisdiction is connected with high-strength bolt,
It is more sensitive to deformation.Excessive deformation not only results in the opening connected between section of jurisdiction, faulting of slab ends, track buckling deformation, influences ground
The operation of iron train, serious person even can because deformed between section of jurisdiction joint open it is excessive caused by leak leak husky phenomenon and cause tunnel into one
Large deformation and damage occur for step.Therefore change stringent to the existing operation carry out such as building foundation and tunnel during project management
Shape control seems most important.
It is often not efficient, economical using deformation rectifying effect of the slurry injection technique of sleeve valve tube to the soil body at present, it is primarily present
Following defect:
First, sleeve valve barrel grouting is difficult to control volume, the location and shape of injecting cement paste, generally can not form continuous stake
Body, especially when groundwater velocity is larger, slurries are often washed away by underground water, it is difficult to be gone out in fixed area setting and hardening, and easily
Existing running pulp alters slurry phenomenon along Grouting Pipe and adjacent structure, and the diffusion of slurries can cause potentially to influence on the construction of periphery engineering,
To underground water and soil is closed on by certain pollution, it is unfavorable for environmental protection.
Second, slurry injection technique of sleeve valve tube once completes slip casting, it is difficult to carry out slip casting supplement to the slurry in the soil body.
Third is when pressure is larger or slip casting position is intensive, and the slip casting of mini-valve tube formula may be filled there is a phenomenon where slurries are counter.
Therefore, the grouting device for researching and developing a kind of controllable soil deformation while controllable slip casting position shape is existing market
The urgent need of development.
Utility model content
To be solved in the utility model is that conventional slurry injection technique of sleeve valve tube is unable to satisfy control soil deformation and slip casting position
The technical issues of setting shape provides a kind of multiple grouting device for controlling soil deformation, i.e., slurries direct weighting is injected geotechnique
In cloth bag, accurately controlling for slurry volume is realized, due to using more slip casting geotechnique's cloth bags, can be realized by repeatedly injecting slurries
Subtle control to soil deformation, the length for changing simultaneously different geotechnological cloth bags can also realize the deformation control of various soil mass depth
System.Therefore in this technique, settable slip casting number, slip casting depth, concentrate grouting pressure, and object construction force is determined in increase
Tropism.
In order to solve the above-mentioned technical problem, the utility model proposes it is a kind of for control soil deformation multiple slip casting dress
It sets, including slip casting core pipe and outer tube, the outer tube includes the arc section of jurisdiction of 2~6 mutual obvolvents, is set in the outer tube
There are multiple geotechnological cloth bags, the top of multiple geotechnique's cloth bags is concordant and than being higher by 0.3~0.5m at the top of the outer tube sleeve, described outer
Casing is externally provided with multiple binding items.
Further, the utility model is used to control the multiple grouting device of soil deformation, wherein multiple geotechnique's cloth bags
Length is identical, as shown in Figure 3.
The length of multiple geotechnique's cloth bags is different, the length of multiple geotechnique's cloth bags according in the outer tube from center along diameter
To successively reducing outward, the geotechnological cloth bag of different length is distinguish in different colors.
The spacing of the binding item is 1m.
The number of geotechnological cloth bag is in the outer tube: when the diameter of the outer tube is 300mm, the number of geotechnological cloth bag
It is 200, when the diameter of the outer tube is 200mm, the number of geotechnological cloth bag is 100, and the diameter of the outer tube is
When 500mm, the number of geotechnological cloth bag is 600.
Diameter after the interior geotechnological cloth bag is propped up is 20mm.
The material of the arc section of jurisdiction is rubber or PVC.
Compared with prior art, the utility model has the beneficial effects that
(1) the utility model can realize precise controlling: slurries (cement grout and waterglass) direct weighting be injected impermeable
Among the geotechnological cloth bag of water, accurately controlling for slurry volume is realized by multiple slip casting, while preventing and returning phenomenon on slurries,
Improve the accuracy of slip casting positioning.
(2) the utility model can realize orientation correction: the length due to can change geotechnological cloth bag can control different depth
Soil deformation, therefore in this project, length of the geotechnological cloth bag along correction direction is larger, concentrates grouting pressure, increases pair
The directionality of object construction force realizes orientation correction and improves slip casting efficiency.
(3) the utility model can realize multiple slip casting: due to being configured with diameter after the completion of the more slip casting of number in casing
For the geotechnological cloth bag of 20mm, the number by changing slip casting geotechnique cloth bag realizes multiple slip casting.
(4) the utility model can be realized environmentally protective: geotechnological cloth bag avoid slurries in a liquid state with underground water with
Soil body contact, prevents the influence to environment is closed on.
