Description
The present invention relates to a fluid filling material injecting apparatus, and more particularly, to a fluid filling material filling apparatus capable of injecting a filler after mixing residues generated in a civil engineering site and then mixing a solidifying agent and water in the site.
At the time of civil engineering structure construction or pipeline construction which is accompanied by excavation, it is essential to carry out backfilling process after installation of the structure.
Such backfilling process may cause structural damage by varying the earth pressure acting on the structure depending on the degree of its quality.
The main reason for this is that the backwash site is narrow and equipment or manpower is inaccessible.
In order to compensate for these problems, a variety of basic construction works have been carried out according to the ground conditions.
For example, in the case of concrete rigid pipes, concrete foundation is used when the ground is rigid or ordinary soil, in case of underground water leaching ground, it is built up under the concrete foundation, and in the case of soft soil,
In case of soft tube, sand foundation for hard soil or normal soil, sand foundation for welded soft soil and welded wire mesh concrete foundation are to be installed.
As another example, in the case of dike waste water or excellent culverment, abandoned concrete is installed in the case of soil piling or soft ground, and abandoned concrete construction is performed in case of rock excavation or soil excavation.
However, in spite of these guidelines at the time of site construction, it is not sure whether the pipeline or box is caught or damaged.
On the other hand, the basic concept of the earth pressure acting on the buried structure is as follows. In the equilibrium state, the load acting on the buried structure is an environment in which fracture or deformation easily occurs because the vertical load is large and the horizontal load is small.
In addition, the load acting on the underground structure increases more greatly according to the deformation form of the backfill ground.
When the deformation (settlement) of the backfill soil becomes large, the earth pressure acting on the underground structure, especially the upper soilfill, becomes larger as the soil deformation around the structure causes the earth pressure difference on the side of the structure.
In addition, there are traffic difficulties when performing drilling and repair work, civil complaints around the construction site, and defect problems after construction.
For this reason, construction time is limited in order to minimize traffic flow and inconvenience to nearby residents.
Therefore, it is difficult to carry out high-quality construction because of the process characteristics for completing the construction quickly.
As a part of efforts to overcome these problems, a method for manufacturing highly fluidized, highly fluidized soils capable of recycling residues at construction sites (Korean Patent Registration No. 10-0805676, Patent Document 1) And a technique for manufacturing a soil-free fluidized soil using a fire is disclosed.
In the
In order to produce the fluidized soil as in
First, a sample is sorted and analyzed, and a mixing device is used to mix the fire and water with the sample, and an injection device is put into the target site to be constructed.
It is only possible to satisfy the conditions of material recycling by merely utilizing the residue of the construction site. When the sorting, mixing and injection are performed in a narrow space and in a limited time, the effect can be maximized I will.
For example, it is an environment where it is difficult to inject through the equipment such as alternation where an immovable settlement occurs where the fluidized filler can be injected, a bottom of a retaining wall structure, a bottom or side of a waterway or a pipe, or a narrow gap with an adjacent structure.
For this reason, injection of fluidized filler has been performed by manpower until now, but this has been a factor hindering rapid injection operation.
The present invention is to solve the problems of the prior art as described above, and it is an object of the present invention to provide a method and apparatus for sorting offsite soil generated in construction and civil engineering sites by various sorting machines, And then injected into the injection site through a pump and an injection device connected to the mixing and stirring device. Thus, it is possible to perform a rapid process by making it possible to easily fill the filling material by using the field generated soil in the field will be.
Particularly, a space in which a filling material is injected is usually narrow. In this case, a filler is injected in a cramped space by using a connector whose diameter is gradually reduced from that of an injection tube.
In addition, when the connector is not used when the connector is used with the locking device, the connector is fixed while being connected to the injection tube, so that the entire volume can be minimized so that the connector can be used in a cramped space.
In addition, the pumping device is constructed using a hydraulic cylinder so that it can be mounted in a narrow vehicle space, and high-pressure discharge can be performed, so that high-viscosity filling material can be smoothly injected.
According to an aspect of the present invention, there is provided a fluid filled filler injection device including: a base frame mounted on a vehicle; A solidifying

According to the present invention, on-site generated soil generated in construction and civil engineering sites is sorted by various sorting machines, and solidifying agent and water are mixed and stirred directly in the field through a mixing and stirring apparatus to which tanks are connected, It is possible to perform a rapid process by injecting the material to be injected through the pump and the injecting device connected to the injection site.
Particularly, a space in which a filling material is injected is usually narrow, and a connector having a diameter gradually decreasing from that of an injection tube is used to facilitate filling of the filling material in a cramped space.
In addition, when the connector is not used, the connector is fixed while being connected to the injection tube by using a locking device, so that the entire volume can be minimized, and the connector can be used in a cramped space.
Also, the pumping device is constructed using a hydraulic cylinder and can be mounted in a narrow vehicle space, and high-pressure discharge can be performed, so that filling of high-viscosity filler can be smoothly performed.

However, since the filler material is relatively viscous compared to water, it may cause difficulties in suction and discharge with a general pump.
In order to prevent this, a multi-stage pump can be connected, but this is not suitable because the space occupied in the vehicle becomes large.
This is contrary to the object of the injection device of the present invention to make it possible to easily inject the filling material in a place where a relatively large vehicle is difficult to enter.
