Abstract

The utility model discloses a soft raft tied with concrete block, comprising a soft raft pad. The soft raft pad is distributed with fastening strips, and the fastening strips are connected with concrete blocks. The soft raft tied with concrete block connects the concrete blocks to the soft raft pad, the raft pad is tied to ballasts firmly with good integrity, and the ballasts are firm and durable with easy construction and low cost. The raft is arranged in a riverbed, after the riverbed collapses due to water current, the raft pad and the ballasts are combined tightly without disengagement, the raft is clung to the riverbed tightly for a long time, and the water current is effectively prevented from eroding the riverbed. Simultaneously, interstices among the ballasts on the raft pad act on increasing roughness and cleaning sludge, and ballast effect is raised. The soft raft can be used for protecting the bottoms and shoals of spur dikes, closed dikes and near shores.

Description

It is the concrete soft raft of determining

Technical field

The utility model belong to rivers under water river bottom protection protect the device on beach, what be specifically related to that a kind of river bottom protection under water protects the beach is the soft raft of concrete piece.

Background technology

At present that to adopt a kind of be the soft raft of pressing bag is more for the bottom, river course such as the Changjiang river or Jiang Tan.It is that the pressure bag that will sandstone be housed ties up on soft row's pad and sinks to the riverbed, by soft row's pad the riverbed is covered and prevents that the riverbed from being washed away by water.But get loose easily owing to press bag to be washed away sack by water, the sandstone in the bag are flowed out, press bag and soft row's pad to come off, cause soft row's pad can not be close to the riverbed, protect the riverbed effectively in the water midium or long term.

Summary of the invention

It is concrete piece soft raft that the purpose of this utility model is to provide a kind of, to overcome the defective in the above-mentioned soft raft use.

The technical solution of the utility model is: be that concrete piece soft raft comprises soft row's pad, distributing on soft row's pad to connect binds bar, binds bar and connects the concrete piece.

Of the present utility model is that concrete piece soft raft system is connected the concrete piece on soft row's pad, and row's pad binds firm good integrity with ballast carrier, and sturdy and durable, the easy construction of ballast carrier is cheap.This row is laid on the riverbed, and after the current scour subsided, row's pad and ballast carrier contact did not closely break away from, and the row's of making body is close to the riverbed for a long time, effectively prevents the erosion of current to the riverbed.Simultaneously, the effect that the gap between the ballast carrier on row's pad increases rough short silt in addition improves the ballast effect.This soft raft can be used for the river bottom protection under water and the Hu Tan of groynes, closure dam and fish mouth offshore under the various conditions.

The specific embodiment

As shown in Figure 5, distributing on the soft raft pad 1 to connect binds bar 2, and the sinew adding strip 3 that connects on the soft raft 1 presses the position to bind 2 one sections of bars.

As shown in Figure 1, it is a kind of X type arrangement, the concrete piece as shown in Figure 3, the knot bar 5 of setting up departments on the concrete piece 4, the bar 5 that binds on the concrete piece 4 is connected with the bar 2 that binds on the soft raft pad 1.

As shown in Figure 2, it is a kind of D type arrangement, the concrete piece as shown in Figure 4, groove 6 is established in concrete piece 7 both sides, the bar 1 that binds on the soft raft pad 1 passes from the groove 6 of concrete piece both sides concrete piece 5 is connected on the soft raft pad 1.

Using the X type is that concrete piece soft raft protects the beach, and every square metre is protected the beach and reduces expense 45%; Using the D type is that concrete piece soft raft carries out river bottom protection and protects the beach, and every square metre is protected the beach and reduces expense 16%, reduces a large amount of maintenance costs simultaneously.

Claims

1, a kind of is concrete piece soft raft, and it comprises soft row's pad, and it is characterized in that distributes on soft row's pad to connect binds bar, binds bar and connects the concrete piece.

2, be concrete piece soft raft according to claim 1, it is characterized in that connecting on the soft raft sinew adding strip, sinew adding strip presses the position to bind one section of bar.
