Problems solved by technology

At present, the above-mentioned parameters are often collected and archived by manual recording. The recording process is cumbersome, the real-time performance is poor, and it may be imprecise and untrue due to human factors.
However, after the supporting disk is completed, the disk quality is often detected by using a disk diameter detector, and it is impossible to realize the real-time control of the disk forming process while testing the disk quality.

Embodiment 1

[0059] An embodiment of the present invention provides a method for monitoring the formation of cast-in-situ piles with extruded and expanded branch plates. The method includes the following steps:

[0060] Step 101 , according to the requirements for the completion of cast-in-situ piles with extruded and expanded branch plates, pre-set the quality range of the finished piles.

[0061] Step 102 , during the extrusion process using the extrusion machine, collect the first parameter reflecting the quality of the disk in real time.

[0062] Step 103 , comparing the first parameter with a pre-set acceptable range of finished disc quality, and judging whether the first parameter is included in the qualified range of finished disc quality according to the comparison result.

[0063] Step 104, if the first parameter is included in the qualified range of finished disk quality, perform the extrusion process according to the first parameter;

[0064] Step 105 , if the first parameter i...

Embodiment 2

[0069] An embodiment of the present invention provides a method for monitoring the formation of cast-in-situ piles with extruded and expanded branch discs. Combining the content of the above-mentioned embodiment 1, this embodiment will describe it in more detail. The method provided in this embodiment includes the following steps:

[0070] Step 201 , according to the requirements for the production of cast-in-situ piles with extruded and expanded support plates, pre-set the qualified range of finished coil quality, which includes: qualified range of coil diameter, qualified range of disc cavity and qualified range of disc position.

[0071] Among them, the qualified range of disc diameter is [R k / α, (R k +pR k ) / α], R k is the preset disc radius. Those skilled in the art can set the R under the condition that the design of the bearing soil layer meets the bearing capacity requirements according to the bearing capacity requirements of the pile foundation and the actual soi...

Embodiment 3

[0093] This embodiment provides a device for monitoring the formation of cast-in-situ piles with extruded and expanded branch discs. The device includes:

[0094] The preset module is used to pre-set the quality range of the finished pile according to the requirements for the finished pile of the extruded and expanded branch plate grouting pile.

[0095] The collection module is used to collect the first parameter reflecting the quality of the disk in real time during the extrusion process by the extrusion machine.

[0096] The judging module is used to compare the first parameter with the pre-set acceptable range of finished disc quality, and judge whether the first parameter is included in the qualified range of finished disc quality according to the comparison result.

[0097] The first processing module is configured to perform the extrusion and expansion process according to the first parameter if the first parameter is included in the qualified range of disk quality.

Abstract

The invention discloses a method for monitoring finished plates of a squeezed and expanded branch and plate cast-in-place pile and belongs to the field of branch and plate piles. The method includes the steps that the qualified interval of the quality of the finished plates is preset according to the requirement of the finished plates of the squeezed and expanded branch and plate cast-in-place pile; in the squeezing and expanding process of a squeezing and expanding machine, a first parameter reflecting the quality of the finished plates is acquired in the real time; the first parameter is compared with the preset qualified interval of the quality of the finished plates, and whether the first parameter is included in the qualified interval of the quality of the finished plates or not is judged according to a comparison result; if the first parameter is included in the qualified interval of the quality of the finished plates, the squeezing and expanding process is performed according to the first parameter; if the first parameter is not included in the qualified interval of the quality of the finished plates, the first parameter is adjusted till a qualified second parameter reflecting the quality of the finished plates is acquired, and the squeezing and expanding process is performed according to the second parameter. The method can guarantee that detection data of the quality of branches and the plates are more visual and truer, and detection of the quality of the branches and the plates and construction monitoring can be integrated.

Description

technical field [0001] The invention relates to the field of disc piles, in particular to a method and device for monitoring the formation of cast-in-situ piles with extruded and expanded discs. Background technique [0002] Squeeze-expanded cast-in-place pile refers to that after drilling or punching, a special extrusion machine is put into the hole to squeeze out the enlarged bifurcation or conical disk-shaped cavity, and then put it into the steel cage and pour concrete. , forming a pile composed of a pile diameter expansion body and a cylinder body, which is a new type of pile developed on the basis of equal-section bored piles. Environmental protection and many other advantages. Since cast-in-situ piles with extruded and expanded discs can expand the diameter of piles in some sections of piles by extruding and expanding them in different bearing soil layers, the quality of the discs is the key to the success or failure of the pile type. Therefore, it is necessary to t...
