Description

The invention relates to the hydraulic industry and is used to destroy and remove ice on water bodies and streams, in particular, when eliminating congestion and blockages on rivers.

There is a method of installing explosive charges under ice jam on rivers during its liquidation [1]. The essence of the method is that a cable is laid along the bottom of the river until a jam is formed, the ends of which are fixed on opposite banks, and during the formation of the jam a garland of explosive charges with floats is attached to one end of the cable, the cable is pulled until charges are placed under the ice in place congestion and detonate charges.

The disadvantages of this method are the following: The use of explosives is a significant danger.

It is not always possible to predict the location of the congestion. If the river is clogged with ice almost to the bottom, then the application of this method is impossible. To destroy the entire congestion, it is necessary to lay the cable in many places.

A known method of clearing ice from mooring raids [2], including laying a channel in an ice field with an icebreaker, setting cargo on ice and destroying the ice field in places of greatest ice deformation using an icebreaker.

The disadvantage of this method is the inability to use an icebreaker with a mash thickness exceeding 3 m. In addition, the delivery of goods of sufficient magnitude to the installation site is not always possible.

Closest to the claimed device is a device for cutting and removing ice from the channel [3]. It includes cutting organs, a frame, a sled, a shock plate, a guide.

The cutting organs cut two slots on the sides of the future channel. The shock plate breaks off the ice prisms in the channel and removes them to the side under the ice field.

The disadvantage of this device is the inability to remove ice with its considerable thickness and a small layer of water between the bottom and the bottom surface of the ice field.

The purpose of the invention is to increase the effectiveness of measures for the elimination of congestion, blockages on rivers and cleaning water from ice.

An essential distinguishing feature is the use of an excavator in this device.

A significant advantage is that the excavator is the most effective means for breaking and removing ice from the channel.

Figure 1 shows a side view of the present device when creating a channel in ice; figure 2 shows a top view.

The device consists of an excavator 1, barge 2, boat 3.

The device operates as follows. An excavator 1 is mounted on the bow of the barge 2, and a boat 3 is attached to the stern of the barge 2. If the barge 2 is self-propelled, then there is no need for a boat 3. Barge 2, pushed by boat 3 along the riverbed 4, approaches the ice jam 5 with the bow forward. Excavator 1 mounted on the bow of the barge, using its bucket 6 (shovels), begins to dig channel 11 in the ice jam. In this case, he removes ice from the channel using the bucket away from the channel to the ice field in heaps 7. After in congestion 5 a through channel 11 will be made, river water will rush into it and begin to erode the congestion, the level in the river will drop above the congestion. The river will enter its banks, the threat of flooding will disappear.

If necessary, the present device can be used to expand the channel in the ice jam 5. In this case, ice must be removed to channel 11, from where it will be carried away by the current.

In cases where the flow of river 4 does not allow it to come close to jam 5, then in those places where the flow of river 4 is less, it is necessary to dig the bottom 8 with an excavator to an ice jam 11, and then dig a channel 11 in an ice jam 5 with an excavator, as described above.

The advantage of this design is that it allows you to begin the destruction of the ice jam 5 or gorge both above and below the river. After the end of the through channel 11 in a congestion or gorge, the water will not flood down the river with a solid rampart, but will gradually leave the flooded areas. This will give time to make a similar through channel in the congestion located downstream, and avoid catastrophic consequences.

To increase stability, a load of 9 can be installed on the barge.

If necessary, barge 2 and boat 3 can be equipped with anchors 10. When digging a channel, this device can be mounted on an anchor, which will facilitate work. As the channel is manufactured, lowering and raising the anchor 10, the device advances along the channel 11 until it is completed.

The advantage of this device is that for its creation there is no need for the design and creation of special equipment. In a period free from work to eliminate congestion and blockages, the constituent elements of the device are widely used in the river industry and construction.

This device can be used to clean the port water area from ice. The excavator destroys the ice cover and loads the ice onto the barge. As the barge is filled with ice, it is transported outside the port.

It is advisable to use excavators with a bucket in the form of a direct or back shovel, since they allow you to dig channels in strong soils, which can include ice ice jams and glitches.

A rotary excavator may be used in the device. The performance of a bucket wheel excavator is significantly higher than normal. Ice from the excavator is fed to the conveyor, and then away from the channel. Instead of an excavator, a roadheader can be used.

The use of the E 652 B excavator in this device will allow digging a channel 9 m wide and 200 m long in an ice jam with an ice thickness of 4 m per day of continuous operation. This is much more effective than using icebreakers.
