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
The invention belongs to coast environmental protection field of engineering technology, relate to a kind of beach protection and foster beach technology, especially utilize water-permeable pipe to carry out method that beach is supported at sandy beach.
Background technology
Along with the change of global climate and the aggravation of mankind's activity, Coastal erosion has become global disaster.Estimate according to inter-governmental climate change Professional Committee, the sand coast of 70% is corroded in the world.Because China's major part coastline belongs to sand coast, therefore Coastal erosion is very serious, and the average water front erosion rate of moving back is greater than 1.1m/a, and local reaches 5.5m/a or larger.Beach technology is supported mainly by a large amount of sand throwing to seabeach in existing sandy beach, and builds the hard engineering such as a word dam, groynes simultaneously, impels by erosion seabeach broadening and stable.Traditional foster beach technology solves the problem of bank erosion to a certain extent, but also exists significantly not enough.A large amount of artificial sand throwings and hard engineering measure need great fund input on the one hand, and the later stage needs regularly manually to mend sand according to erosion condition, and maintenance cost is high; The hard engineering measure of the Yi Ziba, groynes etc. of the outstanding water surface destroys natural aesthetic feeling and the hydrophilic environment at sandy beach on the other hand, reduces the Tourism Resources Value of seaside region.
Summary of the invention
The object of the invention is the deficiency of supporting beach technology in order to solve tradition, proposing a kind of water-permeable pipe sandy beach and supporting beach method and special water-permeable pipe.The method is particularly suitable for the protection of corrosion type sand coast.
Sandy beach provided by the invention is supported the special water-permeable pipe in beach and is comprised body, and body surrounding is provided with permeable seam, and body upper end is provided with pipe cap, leaves air-vent, air-vent sand prevention porous material shutoff in the middle of pipe cap.The permeable seam of described water-permeable pipe body surrounding is the permeable seam of level.The permeable group that is seamed into of described level is arranged, and all leaves interval along the axial and circumferential directions between each group.Described body and pipe cap are PVC material, and pipe cap is connected with water-permeable pipe body by screw thread.
Beach method is supported at water-permeable pipe sandy beach provided by the invention, brings to the highest water-permeable pipe of climbing between line described in the layout of interval of wave in wave breaking.Described water-permeable pipe can be arranged in parallel, also can interlaced arrangement.
The main construction techniques of the inventive method comprises: measurement and positioning, excavation are cheated groove, squeeze into steel sleeve, connect Pump for drawing sand or water, take out sand, place water-permeable pipe, extracted steel sleeve and backfill covering.
the present invention has the following advantages and effect relative to traditional foster beach measure:
It is simple and convenient that beach method construction is supported at water-permeable pipe sandy beach, and the initial stage drops into little, and later maintenance cost is very low.
Sandy beach water-permeable pipe is imbedded in sandy beach, without other ancillary works measures, can not destroy natural aesthetic feeling and the hydrophilic environment at original sandy beach, drastically increase the Tourism Resources Value of seaside region.

Detailed description of the invention
The present invention is further described with reference to the accompanying drawings.
Embodiment 1, water-permeable pipe
As shown in Figure 1, water-permeable pipe comprises the PVC pipe body and pvc pipe cap 1 of being with permeable seam 2, pipe diameter 150 ~ 300mm, and length is 2 ~ 3m, and pipe shaft is provided with the permeable seam of level, stitches wide 0.3mm.
As shown in Figure 2, the permeable group that is seamed into of described level is arranged, and all leaves interval along the axial and circumferential directions between each group.
As shown in Figure 3 and Figure 4, water-permeable pipe pipe cap 1 is provided with air-vent 3, and air-vent adopts porous material shutoff, ensures ventilative thoroughly not husky.
Embodiment 2, water-permeable pipe sandy beach support beach method
As shown in Fig. 5 to 8, the method main for water-permeable pipe (vertically) is arranged in wave breaking to bring to that wave is the highest climbs between line.Described water-permeable pipe can be arranged in parallel (as shown in Figure 7), also can interlaced arrangement (as shown in Figure 8).
The main construction techniques of the inventive method comprises: measurement and positioning, excavation are cheated groove, squeeze into steel sleeve, connect Pump for drawing sand or water, take out sand, place water-permeable pipe, extracted steel sleeve and backfill covering.
The cardinal principle that beach method is supported at water-permeable pipe sandy beach is: seawater carries silt and pours into sandy beach at the incoming tide, sandy beach is now moistening and unsaturated, a large amount of seawater flows rapidly into inside, sandy beach by water-permeable pipe, the sedimentation that seawater carries is around water-permeable pipe, due to the existence of water-permeable pipe, be deposited on the sand material that the sand material on sandy beach will be taken away more than seawater during ebb tide at the incoming tide, thus slowly deposited in sandy beach, reach sandy beach and support the object of repairing on beach.
Application example 1
In certain tank of Tianjin marine traffic engineering research institute of Department of Transportation, carry out water-permeable pipe sandy beach support beach physical experiments.Continuous print wave action is carried out to the sandy beach of not installing water-permeable pipe, after the slope stability of sandy beach, records stable cross section form, and four water-permeable pipe sand are evenly fixed on slope alluvial section (as shown in Figure 5 and Figure 6).Test is proceeded until sandy beach slope stability under identical wave condition.Contrast arranges that the sandy beach before and after water-permeable pipe is domatic known, and after arranging water-permeable pipe, the position of washing away at sandy beach moves forward about 45.0cm, exceeds 1.9cm, thus reach the object that beach is supported at sandy beach before maximum alluvial aspect ratio stringing.
