3. constructors can visually observe the position of the vibroflotation device, and the vibroflotation device is moved to a positioning point to be constructed by moving the vibroflotation gravel pile machine.
According to the flow, the traditional vibroflotation gravel pile machine can realize pile point positioning only by the mutual matching of operators and construction personnel and is limited by the eyesight of the construction personnel, artificial visual errors exist, and particularly, the visual limitation can be caused by insufficient night construction or illumination, the alignment efficiency is low, the alignment error is large, and the potential safety hazard exists.
In addition, in the vibroflotation construction carried out by the method, when a hard layer, particularly large gravels, is encountered, the vibroflotation device adopting the structure inevitably generates a sideslip phenomenon, so that a pile hole is deflected. When the deflection is light, if the inclined pile hole is not trimmed, the guarantee coefficients of the uniformity and the compactness of the pile diameter of the vibro-replacement gravel pile are influenced, so that the safety of the subsequently formed vibro-replacement gravel pile is poor; if the inclined pile hole is repaired, the vibroflot stops vibroflot construction and repairs the hole in time, which inevitably results in prolonged construction period and increased construction cost. If the deflection is heavy, only the whole pile can be discarded, and the construction progress and the cost are seriously influenced.

Detailed Description
As shown in fig. 1 and fig. 2, which are perspective views of two viewing angles of a vibroflotation gravel pile machine used in the method of the present invention, it can be seen that the vibroflotation gravel pile machine of the present invention includes a hoisting system 100, a drill rod system 200, a vibroflotation device system 400, and an automatic feeding system 500.
The hoisting system 100 comprises a main machine 101 of the vibro-replacement stone pile machine, a mast 102 connected with the main machine and a main hoisting device 501 arranged at the rear end of the main machine 101, and the drill rod system 200 is hoisted through a steel wire rope of the main hoisting device 501 and the mast 102 so as to be vertically arranged under the action of self weight.
The main body 101 is provided with an automatic feeding system 500, which is installed at the rear part of the main body 101 of the hoist system 100 and can be used as a counterweight of the main body 101. The automatic feeding system 500 includes an air pipe winding device 502, a cable winding device 503, and a water pipe winding device 504, and these three devices are set to feed in synchronization with the main winding device 501.
Drill pipe system 200 has a connection section 201 at an upper portion for connection to a wire line of main winch 501, a support section 202 at a middle portion, and a working section 203 at a lower portion for connection to vibroflot system 400 (typically, as shown in fig. 8, a shock absorbing assembly is disposed between working section 203 and vibroflot system 400). The drill pipe system 200 employs a prior art telescoping guide rod, allowing the axial length of the drill pipe system 200 to be adjusted to change the down or up position of the vibroflot system relative to the ground. As shown in fig. 6 and 7, the drill pipe system 200 has multiple layers of casing sequentially sleeved from inside to outside, the connecting section 201 is a top layer casing, the working section 203 is a bottom layer casing, and the supporting section 202 includes one or more layers of middle casings. Wherein, two adjacent layers of sleeves can be connected together by adopting the connecting structure in the prior art, so that the two adjacent layers of sleeves can slide axially smoothly and can be prevented from twisting mutually. In operation, the number and length of the multiple layers of casing in the drill pipe system can be determined according to the use requirement, for example, more than 4 layers of casing can be adopted, and the length of each layer of casing can be 18-25 meters (the length of the top layer of casing can be longer). When the vibroflotation gravel pile machine is used, the length of the multilayer sleeve of the drill rod system can be extended or shortened, and when the multilayer sleeve of the telescopic guide rod extends out completely, the total length of the telescopic guide rod can reach 72 meters or even longer, so that the vibroflotation gravel pile machine can be used for vibroflotation hole forming on a stratum with the depth of more than 50 meters. It should be noted that the coaxiality of every two adjacent layers of sleeves in connection is the same, that is, the sleeves of multiple layers are coaxial after being extended in length, so that the sleeves of each layer are perpendicular to the pile hole in the vibroflotation construction process.
Before the vibroflotation construction of the stratum by the vibroflotation gravel pile machine, the vibroflotation gravel pile machine needs to be moved to the position near the pile point to be constructed, in order to realize the automatic positioning, referring to fig. 13, the invention provides a method for automatically operating the vibroflotation gravel pile machine, the vibroflotation gravel pile machine comprises the devices, wherein the method comprises the following steps:

after the vibroflotation system is aligned with the pile point to be constructed, the verticality of the vibroflotation system on the vibroflotation gravel pile machine is adjusted, so that the vibroflotation system can carry out vibroflotation construction on the pile point to be constructed with the verticality meeting the requirements.
The method for automatically operating the vibroflotation gravel pile machine of the invention is specifically described below.

The construction method comprises the steps of determining a current construction-required pile point to be constructed from a plurality of construction-required pile points, then, obtaining coordinate information of a vibroflotation gravel pile machine in a construction plane coordinate system by a positioning guide system (such as a Beidou positioning system) through longitude and latitude information corresponding to the vibroflotation gravel pile machine (similarly, the coordinate information of the vibroflotation gravel pile machine in the construction plane coordinate system can be obtained through the longitude and latitude information of the vibroflotation gravel pile machine), automatically guiding the vibroflotation gravel pile machine (provided with a positioning antenna on the vibroflotation gravel pile machine) to the pile point to be constructed, adopting the prior art in the guiding process, and adding the equipment number of the vibroflotation gravel pile machine into the position information of the current construction-required pile point.
Wherein, each pile hole operation interface of the vibro-replacement stone pile machine can be shown in figure 18.
S200, after the vibroflotation gravel pile machine is automatically guided to a pile point to be constructed, aligning a vibroflotation device system on the vibroflotation gravel pile machine to the pile point to be constructed;
after the vibroflotation gravel pile machine is guided to the position near the pile point to be constructed by the positioning and guiding system, the vibroflotation system on the vibroflotation gravel pile machine is not always aligned with the pile point to be constructed, namely, the position of the vibroflotation system is not always within the position error range of the pile point to be constructed, therefore, the vibroflotation gravel pile machine needs to be automatically guided to move left and right until the position of the vibroflotation system is within the position error range of the pile point to be constructed. The method for aligning the vibroflotation system on the vibroflotation gravel pile machine to the pile point to be constructed comprises the following steps:
acquiring the position relation between a positioning antenna and a vibroflotation system on the vibroflotation gravel pile machine so as to acquire the real-time position information of the vibroflotation system according to the real-time position information of the positioning antenna;
comparing the real-time position information of the vibroflotation system with the position information of the pile point to be constructed to obtain the distance information between the vibroflotation system and the pile point to be constructed;
and aligning a vibroflot system on the vibroflot stone pile machine to a pile point to be constructed according to the acquired distance information.
Wherein, when obtaining the position relation of locating antenna and vibroflotation device system on the vibroflotation gravel pile machine, need respectively carry out initial positioning to the position of locating antenna and vibroflotation device system on the vibroflotation gravel pile machine through positioning device to confirm the position relation of locating antenna and vibroflotation device system:
the method comprises the steps that initial positioning is respectively carried out on the vibroflotation system and the positioning antenna of the vibroflotation gravel pile machine through positioning equipment, and initial position information of the vibroflotation system and initial position information of the positioning antenna are obtained;
determining the distance between the vibroflotation system and the positioning antenna according to the initial position information of the vibroflotation system and the positioning antenna;
and determining the linear distance between the installation position of the positioning antenna and the vibroflotation system and the included angle between the connecting line of the vibroflotation system and the positioning antenna and the north through the distance between the positioning antenna and the vibroflotation system.
And the obtaining of the real-time position information of the vibroflot system according to the real-time position information of the positioning antenna comprises:
acquiring the rotation angle of the vibroflotation gravel pile machine relative to the north;
and according to the acquired real-time position information of the positioning antenna, determining the real-time position information of the vibroflotation system through the real-time position information of the positioning antenna, the distance between the vibroflotation system and the positioning antenna and the rotation angle of the vibroflotation gravel pile machine relative to the north direction.
During implementation, on the vibroflotation gravel pile machine, the vibroflotation system and the positioning antenna installation position are initially positioned by using handheld positioning equipment (equipment in the prior art can be adopted), the position relation is determined, and when construction is started, the real-time coordinates of the vibroflotation system are obtained through calculation by taking the real-time positioning antenna position information as the basis, and all the coordinates are coordinates in a plane coordinate system.
The vibroflotation system and the positioning antenna mounting position on the vibroflotation gravel pile machine are shown in fig. 14, wherein G is the positioning antenna mounting position, M is the vibroflotation motor mounting position of the vibroflotation system, and the vibroflotation motor position represents the position of the vibroflotation system in construction.
When the vibroflotation system and the positioning antenna are initially positioned (see fig. 14), the position relationship can be calculated by the following formula:
a=x 0 -x′ 0 (1)
b=y 0 -y′ 0 (2)
Figure BDA0003207537890000081
Figure BDA0003207537890000082
in the above formulas:
rho is the linear distance between the installation position of the positioning antenna and the vibroflotation motor;
and the angle between the connecting line of the alpha-vibroflotation motor and the positioning antenna and the north.
When positioning the vibroflotation system and the positioning antenna in real time (see fig. 15), the vibroflotation system position can be calculated by the following formula:
x′ 1 =x1+acosβ+bsinβ (5)
y′ 1 =y1+bcosβ-asinβ (6)
in the formula:
x1, y 1-real-time positioning information acquired by a positioning antenna;
x′ 1 ,y′ 1 -vibroflotation motor real-time position information;
beta-the angle of rotation of the vibroflotation gravel pile machine.
Further, when the vibroflotation system on the vibroflotation gravel pile machine is aligned to the pile point to be constructed according to the acquired distance information, the real-time position information of the vibroflotation system and the position information of the pile point to be constructed are also displayed through a graphical interface (as shown in fig. 16 and 17). And after the real-time position information of the vibroflotation system is obtained, the position information of the pile point to be constructed is taken as a target point, and the direction information of the vibroflotation gravel pile machine which is automatically guided to enable the vibroflotation system to be aligned with the pile point to be constructed is displayed through a graphical interface according to the position and distance relation of the vibroflotation system relative to the target point.
Therefore, the Beidou positioning information is used as the basis for positioning, the distance relation between the vibroflotation gravel pile machine and the pile point to be constructed is visually displayed in a graphic mode, and the vibroflotation gravel pile machine is guided to move forwards, backwards, leftwards and rightwards by constructors through clear distance prompt information so that the vibroflotation device system moves to the pile point to be constructed. After the positioning is completed, the graphic interface prompts that the alignment is completed. The whole construction process can completely realize night construction, such as paying off and point finding, so that the construction efficiency is improved, and the construction period is shortened.
In conclusion, the positioning guide system is adopted to accurately position the vibroflotation gravel pile machine and the pile hole to be constructed in real time respectively, then the vibroflotation gravel pile machine and the pile hole to be constructed are transmitted to the graphical interface of the pile machine to guide a driver to accurately position, the vibroflotation gravel pile machine can be accurately positioned by only one driver in the whole process, the cooperation of measuring personnel is not needed, the manpower is saved, the limitation of the vision of the driver is avoided, the problems of low efficiency and safety at night or under the condition of insufficient illumination are solved, the alignment efficiency is high, and the alignment error is small. In addition, the whole construction process realizes real-time data sharing among the construction unit, the on-duty engineer and the supervision, so that the synchronization between construction and supervision is realized, the coordination cost is reduced to the maximum extent, and the construction efficiency is greatly improved.
S300, after the vibroflotation system is aligned to the pile point to be constructed, the verticality of the vibroflotation system on the vibroflotation gravel pile machine is adjusted, so that the vibroflotation system can carry out vibroflotation construction on the pile point to be constructed with the verticality meeting the requirement.
After the vibroflotation system is aligned with the pile point to be constructed, namely the position of the vibroflotation system is within the position error range of the pile point to be constructed, the verticality of the vibroflotation system on the vibroflotation gravel pile machine is adjusted, so that the vibroflotation system can carry out vibroflotation construction on the pile point to be constructed with the verticality meeting the requirement.
In the process of vibroflotation pore-forming on a complex stratum with the depth of more than 50 meters by the vibroflotation device of the vibroflotation device system 200, because a stratum with the depth of more than 50 meters is a deep covering layer, the upper part is soft and the lower part is hard, the gravel with large particle size is more, the upper part of the upper soft finger is a soft interlayer (such as lake-phase sedimentary silty clay), the lower part of the lower hard finger is a relatively compact hard layer (such as a sand layer or a sand layer with gravel), the vibroflotation device works under the environment of broken stone, sand and slurry, if the vibroflotation device meets a hard stratum, the vibroflotation device is very easy to deflect in the vibroflotation process, so that a pile hole deflects, which causes construction failure and huge loss. Especially when the construction is carried out on the stratum such as the medium-coarse sand layer in the strong earthquake high-rise zone, the inclination of the pile body caused by the inclination of the pile hole causes the immeasurable loss. In order to avoid the situation that the vibroflotation device deflects in the vibroflotation process, the drill rod system and the mast of the hoisting system are arranged in parallel, so that the vibroflotation device system connected with the bottom of the drill rod system is parallel to the mast, and the verticality of the vibroflotation device system can be ensured by ensuring the verticality of the mast; when vibroflotation hole-forming construction is carried out through the vibroflotation device, the verticality of the mast relative to the host machine positioned on the horizontal plane is detected in real time, and the verticality of the mast is correspondingly adjusted according to the detection result, so that the verticality of the mast is ensured to meet the requirement, and the vibroflotation device arranged in parallel with the mast can vibroflotation downwards the construction stratum with the verticality meeting the requirement and form vibroflotation gravel pile holes.
Specifically, the vibroflotation device vertical holding system 300 ensures that the vibroflotation device can vibroflotation downwards towards the construction stratum with the required verticality and form vibroflotation gravel pile holes.

As shown in fig. 11, the mast verticality maintaining device includes: the perpendicularity detection mechanism is used for detecting and processing the perpendicularity of the mast relative to the host machine on the horizontal plane in real time when vibroflotation hole forming construction is carried out through the vibroflotation device; the mast angle adjusting mechanism is used for correspondingly adjusting the perpendicularity of the mast according to the detection result of the perpendicularity detecting mechanism so as to enable the perpendicularity of the mast to meet the requirement.

Specifically, if the perpendicularity of the mast needs to be adjusted, the controller firstly controls the vibroflotation system to stop vibroflotation construction, and the vibroflotation system is lifted up through the hoisting system; then, corresponding actions are executed by controlling the mast angle adjusting mechanism so as to adjust the perpendicularity of the mast to meet the requirements: the PLC controller controls the opening size and the direction of the proportional valve, so that the mast is driven by the deviation rectifying oil cylinder to deflect relative to the host machine to adjust the inclination direction and the inclination size, and the perpendicularity of the mast is within a preset threshold interval meeting the requirement. And finally, lowering the lifted vibroflotation system, and continuing vibroflotation construction on the stratum by using the vibroflotation system.
