Problems solved by technology

On the one hand, a large number of artificial sand throwing and hard engineering measures require a huge amount of capital investment, and in the later stage according to the erosion situation, artificial sand replenishment needs to be carried out regularly, and the maintenance cost is high; The natural beauty of the beach and the hydrophilic environment have been reduced, and the value of tourism resources in the seaside area has been reduced.

Embodiment 1

[0020] Embodiment 1, permeable pipe

[0021] Such as figure 1 As shown, the permeable pipe includes a PVC round pipe body with a permeable joint 2 and a PVC pipe cap 1. The diameter of the round pipe is 150-300 mm and the length is 2-3 m. The pipe body is provided with a horizontal permeable joint with a width of 0.3 mm.

[0022] Such as figure 2 As shown, the horizontal permeable joints are arranged in groups, and intervals are left between each group along the axial direction and the circumferential direction.

[0023] Such as image 3 with Figure 4 As shown, the cap 1 of the permeable pipe is provided with a vent hole 3, and the vent hole is blocked by a porous material to ensure ventilation and impermeable sand.

Embodiment 2

[0024] Embodiment 2, permeable pipe sand beach raising method

[0025] Such as Figures 5 to 8 As shown, the method is to arrange the permeable pipe mainly (vertically) between the wave breaking zone and the highest wave climbing line. The permeable pipes can be arranged in parallel (such as Figure 7 shown), can also be staggered (such as Figure 8 shown).

[0026] The main construction process of the method of the invention includes: measuring and positioning, excavating pits, driving steel casings, connecting sand pumps, pumping sand, placing permeable pipes, pulling out steel casings and backfilling.

[0027] The main principle of the permeable pipe beach maintenance method is: when the tide is high, the seawater carries sediment to the beach. At this time, the beach is wet and not saturated. A large amount of seawater quickly flows into the beach through the permeable pipe, and the sediment carried by the seawater is deposited in the permeable pipe. Surroundings, due ...

Abstract

The invention provides a pervious pipe beach nourishment method and special pervious pipes. Each pervious pipe comprises a pipe body, wherein infiltration slits are formed all around each pipe body; the upper end of each pipe body is provided with a pipe cap; an air hole is formed in the middle of each pipe cap; the air hole is blocked by a cellular sand-proof material. The pervious pipe bodies and the pipe caps are all made of PVC. The pervious pipe beach nourishment method comprises the steps that the pervious pipes are arranged (in parallel or crossly) at intervals between a zone of wave breaking and a highest wave climbing line. The main construction technology of the pervious pipe beach nourishment method comprises measurement positioning, groove digging, steel sleeve driving into the grooves, sand pumping pump connection, sand pumping, pervious pipe placement, steel sleeve pulling out, and back-filling covering. The pervious pipe beach nourishment method has the main advantages that the construction of the pervious pipe beach nourishment is simple and convenient, the early investment is little and the late maintenance cost is low. Moreover, the beach pervious pipes are buried into a beach, other auxiliary engineering measures are omitted, so that the natural beauty and the waterside environment of an original beach are not destroyed, and the tourism resource value of a seaside region is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of coast protection engineering, and relates to a beach protection and beach maintenance technology, in particular to a method for beach maintenance by using permeable pipes. Background technique [0002] With the change of global climate and the intensification of human activities, coastal erosion has become a worldwide disaster. The Intergovernmental Panel on Climate Change estimates that 70 percent of the world's sandy coasts are eroding. Since most coastlines in my country are sandy coasts, coastal erosion is very serious. The average coastline erosion rate is greater than 1.1m / a, and locally reaches 5.5m / a or more. The existing beach maintenance technology is mainly to widen and stabilize the eroded beach by throwing a large amount of sand to the beach and building hard works such as dike dams and spur dams at the same time. The traditional beach raising technology has solved the problem of beach ero...
