Description

Technical Field

[0002] The riparian zone, also known as the shore zone, bank zone, land-water ecotone, etc., is an important transition zone for the exchange of matter, energy, and information between the river ecosystem and the terrestrial ecosystem; in water conservancy projects, revetments play a key role in protecting riverbanks, stabilizing river channel morphology, and maintaining the water ecosystem; traditional revetments have many problems in aspects such as ecology, adaptability, and landscape for the stable protection of riverbanks, the restoration and protection of the water ecosystem, and the beautification of the landscape; for example, traditional revetments mainly use grouted or dry-laid block stones, reinforced concrete, etc. for riverbank protection. Although such revetments have certain effects in flood control and anti-scour, these revetment structures have problems such as expensive materials, difficult construction, and difficult maintenance; traditional revetments are only designed and constructed from the perspective of meeting the basic functions of rivers such as flood control, drainage, shipping, and water diversion, ignoring the survival and development of animals, plants, and microorganisms that are integral to the river as a whole, and rarely considering the impact on the environment and ecology. Such revetments are likely to damage the ecological functions of river channels and cause deterioration of the river ecological environment. Moreover, due to changes in the riverbed, existing revetment structures often lead to the displacement or even collapse of the revetment, or extremely high or low water levels caused by extreme weather. If the position of the revetment and the change in water level cannot be detected and warned in time, irreparable losses will be caused. Summary of the Invention

[0032] In this embodiment, a construction method of a composite water conservancy ecological revetment structure includes the following steps: Step 1: Before construction, first build a water interception dam to block the river water upstream. After cleaning the riverbed 1, dig a trench on the bank of the riverbank 2. During this period, the precast cement foundation can be started. When precasting the cement foundation, only need to build a frame of appropriate size through the geogrid 6 and the closed-cell foam board 5 and pour cement to form the plain cement 4, and then wait for the plain cement 4 to solidify before loading it onto the vehicle and transporting it to the construction site. Then, sink the precast cement foundation into the trench through a crane and arrange it closely along the trench.

[0033] Step 2: After the cement foundation is laid, fill the closed-cell foam board 5 in all the gaps, and then press a layer of marble pressing stone 7 on the cement foundation to ensure the stability of the cement foundation. Then, pave a layer of buffer brick wall 8 on the front end surface of the cement foundation, so that the buffer brick wall 8 bears most of the water flow scouring. Then, pave a layer of polysulfide sealant layer 9 at the connection between the riverbed 1 and the buffer brick wall 8 to ensure that the riverbed 1 is firm and will not submerge due to the eddy scouring at the revetment angle, causing the collapse of the cement foundation. Then, lay an artificial stone pile 10 above the polysulfide sealant layer 9 to protect the polysulfide sealant layer 9.

[0034] Step 3: Install the inclined roof support columns 34 on the front end face of the riverbank 2. Then, erect the horizontal support frame 33 on the inclined roof support columns 34. Next, tightly lay the paving wooden boards 35 on the horizontal support frame 33. Then, install the fixed guardrail 32 on the front end face of the horizontal support frame 33, thus completing the installation of the clear water platform. Then, lay the sidewalk 30 and plant evergreen trees 31 at equal intervals, and install a circular seat outside the evergreen trees 31. Finally, release the upstream river water to complete the construction of the revetment.

[0035] Step 4: Then comes the decoration work. First, place the floating boxes at appropriate positions on the water surface 3 at equal intervals. During the placement, flexibly connect the floating boxes to each other through nylon ropes 13 to ensure the relative distance between the floating boxes. Then, fix the lower end of the adjusting rope 28 below the floating box on the riverbed 1. Then, thread the light belt 38 and the water pipe 39, and connect the water pipe 39 and the nozzle 40 to complete the installation of the water level adaptive adjustment layer. Then, install the hydroponic boxes 36 on the front and rear end faces of the floating box. Then, pass the infusion pipe 37 through the hydroponic box 36, insert aquatic plants into the holes in the perforated board 29, and then pump the heated nutrient solution from the shore into each hydroponic box 36 to ensure the warmth and nutrition of the aquatic plants, completing the installation of the ecological restoration layer, and thus completing all the construction work.

[0036] During the revetment work, the water flow continuously scours the revetment, and most of the wear is borne by the buffer brick wall 8. Once the buffer brick wall 8 is damaged, it can be very conveniently replaced directly, thus avoiding the problem that the wear of the revetment support structure cannot be repaired. The flow of the river water will drive the floating box and the perforated board 29 to displace. At this time, due to the gravity continuously exerted by the counterweight 24, it is converted into the rotational force of the counterweight shaft 16 through the counterweight rope 23 and the first spline sleeve 21, and then converted into the rotational force of the adjusting shaft 20 through the cooperation of the first bevel gear 18 and the second bevel gear 19. Finally, it is transmitted to the adjusting rope 28 through the second spline 25 and the second spline sleeve 26, making the adjusting rope 28 continuously tightened, thus offsetting the thrust of the water flow and ensuring the stable position of the aquatic plants. Similarly, when the water level changes, the adjusting rope 28 can also automatically adjust its length under the action of the gravity of the counterweight 24 to ensure the stable position of the aquatic plants. The water pump on the shore also supplies water to the water pipe 39, so that the water flow sprays out from the nozzle 40. At this time, the water flow sprays out from the obliquely arranged spray holes to drive the rotating head to rotate and spray the water evenly, thus facilitating the flushing operation of the surface dust of the planted aquatic plants. And the lidar 41 continuously scans the riverbed 2 and the revetment structure to obtain three-dimensional data and analyze and warn of the micro-displacement of the revetment and the real-time change of the water level, facilitating the early handling of possible crises.

[0037] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific embodiments of the present invention are limited thereto. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the present invention, several simple deductions or substitutions can still be made, and all should be regarded as falling within the scope of patent protection determined by the claims submitted for the present invention.
