Description

Technical Field

[0001] The utility model relates to the technical field of vibro-rock pile construction, in particular to a vibro-rock pile funnel-type casing device. Background Art

[0002] During the construction of vibro-compacted stone piles, firstly, a slot is drilled in the foundation by means of a drilling rig or other equipment, and then a vibrating water jet device is inserted into the slot, and stones are transported above the slot for feeding. As the stones fall into the slot, the vibrating water jet device operates to break the fallen stones and fill the slot, and the slot is gradually filled upward to form a vibro-compacted stone pile. In the construction process of the prior art, due to the accumulation of stones at the hole mouth for falling, the hole mouth is prone to collapse, and it is necessary to design a funnel-type casing device for vibro-compacted stone piles to solve the above problem. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a funnel-type casing device for a vibro-impacted crushed stone pile, which solves the problem that the hole opening of the vibro-impacted crushed stone pile in the prior art is easy to collapse during construction, and has the characteristics of being able to effectively support the hole opening and avoid collapse.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a funnel-type casing device for vibro-compacted gravel piles, comprising a casing body, which is a hollow structure with upper and lower openings; the cross-section of the casing body is rectangular, and the cross-sectional area of ​​the casing body gradually decreases from top to bottom to form an inverted cone structure.

[0005] Preferably, the inner wall of the casing body is provided with a guide groove, and the guide groove cooperates with the guide rod of the vibrator to limit the position.

[0006] Preferably, a lifting ring is connected to the top of the casing body to cooperate with the crane.

[0007] Preferably, a level bubble is fixed to the top edge of the casing body.

[0008] The utility model has the following technical effects:

[0009] Compared with the prior art, the present device solves the problem that the hole mouth of the prior art vibratory crushed stone piles is prone to collapse during construction, and has the characteristics of being able to effectively support the hole mouth and prevent collapse; the groove on the inner wall of the casing body can cooperate with the guide rod of the vibrator to ensure that the guide rod falls in the same direction, avoiding the deviation of the vibration path caused by the rotation of the guide rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0011] Figure 1 It is a top view schematic diagram of the utility model;

[0012] Figure 2 It is a main schematic diagram of the utility model;

[0013] Description of the reference numerals in the figure: casing body 1, guide groove 2, lifting ring 3, level bubble 4. DETAILED DESCRIPTION

[0014] like Figure 1~2 As shown, a funnel-type casing device for vibro-compacted gravel piles comprises a casing body 1, which is a hollow structure with upper and lower openings; the cross section of the casing body 1 is rectangular, and the cross-sectional area of ​​the casing body 1 gradually decreases from top to bottom to form an inverted cone structure.

[0015] Preferably, the inner wall of the casing body 1 is provided with a guide groove 2, and the guide groove 2 cooperates with the guide rod of the vibrating machine to limit the position.

[0016] Preferably, a lifting ring 3 is connected to the top of the casing body 1 to cooperate with a crane.

[0017] Preferably, a vial 4 is fixed to the top edge of the casing body 1 .

[0018] The working principle of the utility model is as follows:

[0019] The casing body 1 is made of steel plate into an inverted cone shape, and the two sides of the funnel-type casing are grooved. When in use, the casing is first hoisted to the mouth of the slotted hole for installation, and then the distance from the top, middle and bottom of the casing to the vertical line is measured with a plumb bob and a steel tape measure to keep the casing vertical. The casing is symmetrically filled and compacted around it. After the compaction is completed on all sides, the center position and oblique straightness of the casing are remeasured again, the elevation of the top of the casing is measured, and the depth required for drilling is calculated based on the designed height of the pile top.

[0020] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
