Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.

Referring to fig. 1 and 2, the present invention provides a high efficiency pile protection sleeve 100, which is disposed under a pile leg, and has a water inlet 110 in the middle and water outlets 120 at both sides.

The water inlet 110 of the pile driving protection sleeve 100 is in sealed connection with the flushing port on the leg, so that water sprayed from the flushing line on the leg can flow into the pile driving protection sleeve 100 through the water inlet 110.

The water outlets 120 on both sides of the pile driving protection sleeve 100 are used for dividing water entering the pile driving protection sleeve 100 and discharging the water from both sides of the pile driving protection sleeve 100.

Thus, after the water sprayed out from the flushing pipeline is shunted and sprayed out through the pile flushing protective sleeve 100, even if the water is flushed back, the silt mixed with the water can only flow into the pile flushing protective sleeve 100 from the water outlets 120 on the two sides and can not flow into the pile legs, so that the pipeline blockage can not be caused, and the pile flushing efficiency is greatly improved.

The pile-punching protection sleeve 100 is in an inverted T shape integrally and specifically comprises at least two groups of connecting seats 200 and a pipe body 300, wherein the pipe body 300 is horizontally arranged below a pile leg.

The connecting bases 200 are respectively vertically arranged between the spud legs and the tube body 300, the bottom end of each connecting base 200 is communicated with the tube body 300, the top end of each connecting base 200 is provided with a water inlet 110, and the two sides of the tube body 300 are provided with water outlets 120.

In order to improve the installation strength, a reinforcing plate is provided on each of the connection sockets 200.

The water sprayed from each flushing pipe enters the connecting base 200 through the water inlet 110, flows into the middle of the pipe 300, and then flows to the two ends of the pipe 300 to be discharged through the water outlet 120.

The cross-sections of the connecting socket 200 and the tube body 300 may be rectangular or circular.

In addition, since the punching force of the washing water is weakened when the water flowing into the connector housings 200 flows into the pipe body 300 again to be branched, in order to increase the punching force, first guide plates are provided on both sides of the connection end surface of the pipe body 300 and each connector housing 200.

The included angle between the first guide plate and the tube body 300 is 120-160 degrees.

Like this, when the water in the connecting seat 200 flowed into in the body 300, at first can carry out the reposition of redundant personnel fast through the first guide plate on the side of body 300 and connecting seat 200 connection terminal surface both sides, the weakening of the punching press power of reducible sparge water like this to improve the punching press power of sparge water.

Although, wash the water of pipeline spun through towards stake protective sleeve 100 reposition of redundant personnel back of redundant personnel blowout, silt is difficult to flow into in the spud leg, but can flow into towards stake protective sleeve 100 in, although the continuous accumulation of silt can fill up towards stake protective sleeve 100, can influence the circulation of sparge water like this and can flow into in the spud leg along connecting seat 200.

This application still is equipped with the barrier mechanism that blocks silt in wash pile protection sleeve 100.

The blocking mechanism is specifically disposed within the tube 300 and includes a first blocking device 400 and at least one set of second blocking devices.

The first blocking device 400 is specifically located below the interface between the tube 300 and the connecting socket 200.

Each set of second blocking means comprises two blocking means 500, the two blocking means 500 being symmetrically arranged on both sides of the first blocking means 400.

Thus, when the water mixed with silt flows into the pipe 300 from the water outlets 120 on both sides of the pipe 300, the water passes through the blocking device 500 and the first blocking device 400 in sequence, the blocking device 500 and the first blocking device 400 block the silt in the water respectively, and when the blocked water is discharged again, the silt outside the blocking device 500 and the first blocking device 400 can be flushed out, so that the pipe 300 is free of silt.

With reference to fig. 3 and 5, in order to save costs, the first block 400 is composed of several layers of first blocks 410 distributed in an array and each of them is composed of several layers of second blocks 510 distributed in an array.

In order to increase the punching force of the washing water, the diameter of the second stone block 510 is smaller than that of the first stone block 410, and the distance between adjacent two second stone blocks 510 is smaller than that between adjacent two first stone blocks 410.

Thus, the washing water first enters the first blocking means 400 having a large interval when passing through the divided flow, and then passes through the blocking means 500 having a small interval, and since the diameter of the first stone 410 is large, the gap therebetween is also large, so that the water pressure is weakened only slightly when the divided flow is performed.

Furthermore, in order to improve the blocking efficiency, each second block 510 is located just between two first blocks 410, so that the silt passes through the layer-by-layer blocking of the second blocking device and the first blocking device 400 in sequence.

Referring to fig. 4 and 6, the present application also provides another structure manner of the first blocking device 400 and the blocking device 500, the first blocking device 400 specifically includes a plurality of layers of first stacking plates 600 placed on the upper right, a plurality of stone placing rings 610 are provided on each layer of stacking plates 600 at regular intervals, and a reinforcing rib 620 is connected between every two adjacent stone placing rings 610, so that the first stones 410 can be placed in each stone placing ring 610 respectively.

Similarly, the blocking device 500 specifically includes a plurality of layers of second stacking plates 700 arranged on the upper right, a plurality of stone placing rings 710 are arranged on each layer of second stacking plates 700 at regular intervals, and a reinforcing rib 720 is connected between every two adjacent stone placing rings 710, so that the second stones 510 can be respectively placed in each stone placing ring 710.

Thus, the above embodiment can improve the overall strength of the first stopper 400 and the stopper 500, and prevent the first stone 410 or the second stone 510 from being scattered by water.

In addition, to improve the filtering efficiency, two adjacent layers of first piled plate 600, each stone relief ring 610 on one layer being located just in the gap between two adjacent stone relief rings 610 on the other layer, and likewise two adjacent layers of second piled plate 700, each stone relief ring 710 on one layer being located just in the gap between two adjacent stone relief rings 710 on the other layer.

Furthermore, the stones of the first blocking device 400 and the blocking device 500 can be stacked, or can be stacked randomly, and only the silt needs to be blocked.

In order to further increase the impact force of the washing water, a second baffle is respectively arranged between the first blocking device 400 and the blocking device 500 and between two adjacent blocking devices 500.

In addition, referring to fig. 1, in order to facilitate installation and detachment and improved water impact force, the water outlets 120 at the two ends of the pipe body 300 are respectively provided with a hole plate 121, the hole plate 121 is provided with a plurality of water outlets, and the hole plate 121 is detachably and fixedly connected with the pipe body 300 through a flange.
