Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Examples

An improved vibroflotation device is shown in figures 1-2 and comprises a tube body 1 and a vibroflotation head 2 connected with the tube body 1, wherein the side wall of the vibroflotation head 2 is in a conical shape, and the device has low power consumption. Integrative connection steel member 3 on the lateral wall of drift 2 shakes, 3 circumference of steel member distribute and set up along the axial, shake drift 2 go up with body 1's junction department be equipped with protection strip 4, protection strip 4 sets up along circumference alternately.

Specifically, the steel members 3 are protection steel plates or protection steel bars, and the steel members 3 on the side wall of the vibrating punch head 2 are arranged at intervals; 2 lateral walls of drift that shakes are equipped with small opening 5, and steel member 3 is located between adjacent small opening 5, and the normal ejection of compact of protection small opening 5.

Further, a protection steel plate or a protection steel bar is also circumferentially arranged at the end of the pipe body 1, as shown in fig. 3, the protection steel plate/protection steel bar structure on the pipe body 1 corresponds to the protection steel plate/protection steel bar on the side wall of the vibro-pin 2, and the end of the protection steel plate or protection steel bar is connected with the protection bar 4 at the corresponding position. The protection strip 4 welded on the side wall of the vibration punch 2 adopts a D707 tungsten carbide wear-resistant welding rod, D707 is a tungsten carbide surfacing welding rod with a low sodium bicarbonate type coating, direct current reverse connection is adopted, the tungsten content of surfacing metal reaches 6% -12%, the welding quality is good, and the weak part of the joint of the vibration punch 2 is strengthened.

Through 2 easy wearing and tearing, weak positions at the drift that shakes add respectively and establish steel member 3 and protection strip 4, the 2 structures of drift that shake are protected, reduce the degree of wear in the 2 work progress of drift that shake, increase of service life. After the measures are taken, the failure frequency of the vibroflotation heads 2 is obviously reduced, the time for overhauling the equipment is shortened, and the construction efficiency is improved.

For further reducing the drift maintenance time that shakes long, influence big problem to the gravel pile ship group, prepare 1 set of drift spare parts that shakes at least in the machine shop of repairing to guarantee to shake the drift and take place to damage, when unable short time internal repair at any time, can in time change the drift that shakes, do not influence the gravel pile construction.

The method is characterized in that weak parts which are easy to wear of the vibroflots are reinforced and then applied to the onsite construction of coral reef calcareous sand sea areas, according to vibroflot fault frequency statistics, the vibroflot fault frequency is reduced from 2 times per week before activity to 0.75 times per week on average, and the occurrence frequency is reduced by 62.5%. Meanwhile, the average overhaul time of the vibrating punch head is reduced from 12.76h per week before activity to 3.75h per week, the overhaul time is reduced by 70.61%, and the effect is remarkable.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
