Abstract
The utility model relates to a geotechnical engineering deep foundation pit construction field, a concrete overhead high pressure jet grouting pile machine revolves spray tube supports device, characterized by: including base plate and stay tube, the base plate is equipped with the through -hole in central authorities, the stay tube is vertical locate on this through -hole and substrate connection, the four corners of this base plate still is equipped with the connecting hole, the internal diameter of this stay tube with revolve spray tube external diameter phase -match. This device is with the common material producing of job site, and convenient and fast is simply easily looked for, is makeed to the material, and it can keep the high pressure jet grouting pile machine when revolving the spray tube overlength and spill over the bracket height, can once promote to becoming the stake height and revolve a spray tube not break to effectively promoted the efficiency of construction, and to a certain extent, the guide limit function of device the straightness controllability that hangs down that whole high pressure jet grouting pile machine becomes the stake has been promoted.
Description
Technical field
The utility model relates to geotechnical engineering deep foundation pit construction field, concrete a kind of overhead jet grouting pile driving machine churning pipe supporting device.
Background technology
High-pressure rotary jet grouting pile utilizes rig to creep into certain depth in the earth formation, utilize high-voltage generator, the cement slurry good by mixing or other soil body is cut with the form of high-pressure spray in order to improve the chemical pulp body of soil structures performance, slurry body and soil shear failure mixing, until condensing into the column induration of certain diameter, thus ground is made to reach the object of reinforcing. This engineering method is applicable to various soft layer, it is possible to significantly improving slip resistance and the mechanical property of the soil body, Construction Vibration is little, noise is lower, and material is easily looked for, and mechanical arrangements is complete, and construction application face is wider.
In high-pressure rotary jet grouting pile construction process, it has been found that following problem: overhead jet grouting pile driving machine, due to performance requriementss such as mechanical stabilities, can not increase arbitrarily frame height, and normal framework is up to 30m. and the length of churning pipe is determined by the construction depth of rotary churning pile, when carrying out darker jet grouting pile construction, the length of churning pipe often beyond the height of stake machine frame, when the usual rotary churning pile degree of depth is about 35 ~ 40m, it is necessary to it is 4 ~ 10m that churning pipe is once lifted beyond the height of frame. and in churning process, clamp churning pipe with lifting device and carry out moving up and down and rotary-jet action of churning pipe, under the requirement of continuous operation, when carrying out the action of up tube drawing, churning pipe upper end often needs to overflow across frame height, it is not easily too many that this faces sky fillet height, it is generally 2 ~ 4m, because facing empty churning pipe to occur being similar to the same rocking action of cantilever lever because there is no impetus when mechanical execution, as sky length is faced in upper end, to exceed frame height too many, the amplitude then rocked is much bigger, easily make to face empty churning pipe to fracture, cause tremendous economic loss and incur loss through delay man-hour.
Through existing literature search is found; this type of problem there is no good settling mode to meet disposable Upgrade Problem when churning pipe is crossed long at present; usually it is all when churning carries pipe to certain altitude; shut down release; add pressure rotary-spraying again after installation is dismantled and reconnected to lower end churning pipe and carry pipe; repetitive operation is until lifting churning is to stake end; this operating process is complicated; expend man-hour; the stake of construction is because the pause of operation causes pile quality poor; affect construction effect, and machinery and churning pipe are easily caused damage by the operation repeatedly shutting down and tearing open pipe.
Summary of the invention
Time the purpose of this utility model is to solve overhead high-pressure rotary-spray pile driving construction; the problem that churning pipe lift height easily fractures when exceeding frame height; offer one churning pipe in lifting high-pressure rotary-spray pipe process is grown when exceeding frame excessively; protection churning pipe is once promoted to stake top and does not fracture, and effectively improves the device that overhead high-pressure rotary jet grouting pile promotes working efficiency.
In order to achieve the above object, the utility model is achieved in that
A kind of overhead jet grouting pile driving machine churning pipe supporting device, comprising substrate and supporting tube, substrate is provided with through hole in central authorities, and supporting tube is vertically located on this through hole and is connected with substrate, the corner of this substrate is also provided with and connects hole, and the internal diameter of this supporting tube mates mutually with churning pipe external diameter.
Described overhead jet grouting pile driving machine churning pipe supporting device, is the stable connection strengthened between supporting tube and substrate, also comprises support bar, and the two ends of described support bar are connected with supporting tube and substrate respectively.
This device common materials of working-yard makes, material is simple and easy to look for, fast easy to make, it can keep jet grouting pile driving machine when long spilling frame height crossed by churning pipe, can once be promoted to pile height and churning pipe does not fracture, thus effectively improve operating efficiency, and to a certain extent, the guiding limit function of device improves the degree control ability of whole jet grouting pile driving machine pile.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this application of installation at overhead high-pressure rotary-spray pile frame.
Fig. 2 is the vertical view of this device.
Fig. 3 is the section of structure of this device.
Embodiment
Below by way of specific embodiment, the utility model is described further.
As shown in Figure 1, overhead jet grouting pile driving machine churning pipe supporting device is installed on jet grouting pile driving machine frame lifting device.
As shown in Figure 2, described device is made up of substrate 1, support bar 3 and supporting tube 2. Substrate 1 is cut by common steel plate, is 20mm, long 600mm, wide 400mm. Substrate 1 center drilling, aperture 55mm. Substrate 1 four jiaos of perforates, are connected and fixed for the lifting lifting gear with rotary churning pile machine, and are used as the base of supporting device.
As shown in Figure 3, the support bar 3 of described device is angle steel, and specification is 25 �� 25 �� 5mm, and length is 4m, welds with substrate 1 and supporting tube 2 respectively at two ends at an angle with vertical plane, for supported pipe 2, it is to increase the stability of whole device.
As shown in Figure 2 and Figure 3, the supporting tube 2 of described device is internal diameter 55mm, the steel pipe of wall thickness 10mm, and steel pipe bottom is welded on substrate 1 with internal diameter align substrates 1 centre hole position, outside, and supporting tube 2 mainly plays a part to guide and helps churning pipe 5.
