Gabion 1 in above-mentioned dam body and river course drop can have identical structure.Usually, with reference to shown in Fig. 2, gabion 1 includes cage body 11, be filled in this cage body 11 lump material 12 and perfusion are to the Binder Materials 13 in this cage body 11, and the gap between the adjacent described lump material 12 of this Binder Materials 13 at least filling is to be bonded as overall structure by the described lump material 12 in described cage body 11.
This utility model utilizes the gabion 1 being perfused with Binder Materials 13 to form dam body and river course drop, it is possible to first make the cage body 11 being filled with lump material 12 play a role in such as duration anxiety or emergency work, it is possible to rapid construction under water；Potting compound gel material 13 under dry field condition after treating such as flood season, thus at least in early stage by the restriction of dry field construction.Mechanized construction can be conveniently realized when loading lump material 12, and such as can using building waste etc. as lump material, consequently facilitating improve efficiency of construction, reduce cost.
For gabion 1 self, this utility model is by using Binder Materials 13, significantly enhance its globality, even if in use occurring cage body 11 to damage situations such as (such as due to corrosion), it also is able to be easy to keep its rock-steady structure, avoid losing efficacy under such as water impact, there is the advantages such as structural strength height, good endurance, erosion resistibility are strong.
It should be appreciated that above-mentioned Binder Materials 13 generally irrigates on the upside of cage body 11, and main natural flow under gravity.Thus, the Binder Materials 13 of perfusion can comparatively be fully filled the gap between each lump material 12, to have the structure being formed as tightly attached to each other on the whole.
In dam body of the present utility model and river course drop, the cage body 11 of gabion 1 can be made up of multiple suitable material (such as bamboo chip), as long as it can be easy to filling lump material 12 and can limit the lump material 12 of filling within the suitable length time (before Binder Materials 13 solidification such as irrigated).Normally, cage body 11 can include the net cage that metal mesh sheet is made, can load lump material 12, it is possible to have higher intensity.Such as, in a preferred embodiment, cage body 11 has is set up, by zinc-plated mesh sheet, the netted case formed, and this netted case defines inner space, is used for loading lump material 12.The cage body 11 of this structure has higher intensity, not cracky under the External Force Actings such as impact, but is such as prone to corrosion under current scour effect.Alternatively, above-mentioned netted case can also be moulded mesh sheet erection by leaching and form, although to mould mesh sheet basic it can be avoided that above-mentioned corrosion problem in leaching, but there is the shortcomings such as inflammable.Therefore, it can select according to use occasion the material of this netted case, and be not limited to above two selection.

Although additionally, cage body 11 has cubic shaped for easy construction in illustrated preferred embodiment, but this utility model is not limited to this, it can also be formed as the shape that other are arbitrarily suitable.It addition, netted case size is unsuitable excessive or too small, to ensure to save on good integrity basis manufacturing cost, for this, netted case highly preferred for 1.5m～2m, length and width is respectively preferably 2m～3m.
Just as described above, lump material 12 can be block stone or cobble.Wherein, building a dam and building in river course drop process, cobble generally can be drawn materials nearby, thus saving transport and material cost.But this utility model is not limited to this, as long as lump material 12 has suitable intensity and can be bonded as entirety by Binder Materials 13 and belong to concept of the present utility model.For example, it is possible to utilize construction waste etc. as lump material 12 as described above.
For Binder Materials 13, equally possible have multiple choices, as long as it is easy to be poured and fill in the gap between lump material 12, so that lump material 12 is bonded as overall structure, belongs to protection domain of the present utility model.In this case, Binder Materials 13 typically requires and has good mobility, in order to flow in the gap between lump material 12 after perfusion.But, the mobility of Binder Materials 13 may result in it and runs off from the mesh of such as netted case, wastes Binder Materials 13, increases cost.For this, in a preferred embodiment, it is possible to the bottom of such as cage body 1 lay permeable fabric, to be limited at inside cage body 11 when Binder Materials 13 flows to bottom cage body 11 along the gap between lump material 12.It can be seen that Binder Materials 13 substantially mainly under gravity natural flow to fill the gap between lump material 12, thus be likely to and run off from the sidewall of cage body 11, described permeable fabric can also be also provided with in the circumference of cage body 11 for this.Typically, permeable fabric described herein can be such as non-woven fabrics, have yarn fabric etc..
This utility model one comparatively preferred embodiment in, Binder Materials 13 can be pea gravel concreten, self-compacting concrete and/or mortar.For different Binder Materials 13, there is larger difference in its comprcssive strength, mobility, adhesion strength etc..It is said that in general, in order to ensure the bond strength between lump material 12, it is possible to judged whether its mobility etc. is suitable to corresponding application scenario by the groundwater increment of Binder Materials 13.It addition, in this utility model dam body and river course drop, gabion 1 is not limited to use single Binder Materials 13, for instance can have pea gravel concreten and self-compacting concrete, suitably to reduce cost when ensureing the bond strength of lump material 12 simultaneously.For example, it is possible to first perfusion self-compacting concrete is to suitably height (as from cage body 11 top 150mm), then perfusion pea gravel concreten is to desired height.Preferably, select self-compacting concrete as described Binder Materials 13 (one of) time, this self-compacting concrete at least meets following one: maximum coarse aggregate size is not more than 20mm, and the slump is 650mm～750mm, and the V-arrangement funnel delivery time is 7s～25s.This preferred version is due to without vibrating operation and being greatly decreased between perfusion, and reduces labor intensity, improves production efficiency.And, it is also possible to effectively reduce blibbing or the probability of voids and pits appearance, it is ensured that higher construction quality.It addition, self-compacting concrete can also make full use of coal dust ash, slag powders, stone powder isoreactivity or inertia admixture, to reduce cement consumption, absolute temperature rise reduces, it is simple to simplifies or even cancels temperature control measures.
In this utility model, for purposes such as easy constructions, it is not absolutely required to be piled up by the plurality of gabion 1 after forming gabion 1 and drop together into above-mentioned dam body and river course, but can have dam body and the river course drop of above-mentioned gabion 1 in the formation in the process of setting of building that dam body and river course drop.
For example, referring to each dam layer 2 of the dam body shown in Fig. 1, first can be filled with lump material 12 cage body 11 stacking (piling up) setting continuously by multiple, then set up template in periphery and form lift surface and then overall perfusion.Herein and the following stated overall perfusion, refer to that aforementioned cage body 11 stacking continuously completes perfusion in one-stop operation, and make mutually to bond between each cage body 11.This can improve the intensity of barrier wall structure further, and is easy to lifting construction efficiency.In one-piece casting process, should adopting multiple spot casting method, build spacing a little and be not more than 3m, to ensure density, this is comparatively important for dam body intensity.
Each dam layer 2 can have multiple lift surface, preferably, each lift surface is being of a size of 15m～25m along the length direction of dam body, and is provided with cystosepiment between adjacent described lift surface, to allow such as concrete expansion after perfusion, it is to avoid or reduce the probability of crack generation.
It addition, from figure 1 it appears that at the multiple dams layer 2 arranged along the thickness direction (i.e. left and right directions in Fig. 1) of dam body, face slab for water retaining 3 can also be provided with between adjacent dam layer 2.Face slab for water retaining 3 can also be formed with in the side towards upstream water body of dam body, pass through embankment seepage reducing moisture.This face slab for water retaining 3 can be formed in a variety of forms, as long as it can stop moisture to pass through embankment seepage (being not limited to moisture completely isolated), belongs to concept of the present utility model.In a preferred embodiment, face slab for water retaining 3 can be castable, for instance, for the face slab for water retaining 3 towards water body side, upstream of dam body, it is possible to formed by the technique such as formwork, cast.And for the face slab for water retaining 3 between adjacent dam layer 2, then can by above-mentioned overall perfusion with the moulding by casting simultaneously of the Binder Materials 13 in gabion 1, in this case, face slab for water retaining 3 is substantially of identical composition with Binder Materials 13.Have an advantage in that, it is possible to utilize face slab for water retaining 3 to make adjacent dam layer 2 be connected to each other, improve globality further, and without additionally connecting adjacent gabion 1, Simplified flowsheet.It is understandable that, although the face slab for water retaining 3 between the adjacent dam layer 2 shown in Fig. 1 and Fig. 3 relatively thick (namely layer 2 spacing in adjacent dam is bigger), but in force without deliberately retaining the large pitch adapting to this relatively thick face slab for water retaining 3 between adjacent dam layer 2, but adjacent dam layer 2 can be made to arrange with contacting with each other, in casting process, only between adjacent dam layer 2, form described face slab for water retaining by the natural flow of castable.
With reference to Fig. 4, it is shown that be the river course drop including multiple drop step 4, the plurality of drop step 4 is horizontally disposed respectively along the bearing of trend in river course and sets up (after namely previous drop step rides upon, one drops on step) continuously.Each described drop step 4 can be laid by the gabion 1 of a layer or the less number of plies and form, and this river course drops comparatively suitable in the river course that drop is less.
With reference to Fig. 5, it is shown that being the river course drop including multiple drop wall 5, each drop wall 5 is intervally installed, and along direction, river course, its extended height successively decreases.The construction technology of this river course drop is referred to the work progress of above-mentioned dam body, does not repeat them here.
