背景技术Background technique

随着城市化进程的推进,传统的挡墙结构已无法满足人们对生态景观的需求。近些年,城市内涝的频繁发生,促使建设“海绵城市”的理念得以推广,其中就包括了建设生态河道及其附属结构。With the advancement of urbanization, the traditional retaining wall structure can no longer meet people's needs for ecological landscape. In recent years, the frequent occurrence of urban waterlogging has promoted the concept of building a "sponge city", which includes the construction of ecological rivers and their subsidiary structures.

为了改善城市积弊和美化环境,越来越多的河道生态化改造工程列入建设计划中。目前常见的改造方式多为将现状护岸拆除,重建新型生态护岸,但存在对周边环境负面影响大、资源浪费、能耗高、造价高等一系列弊病,同时由于土地资源日益紧缺,产生的建筑垃圾也无处安置。In order to improve the urban disadvantages and beautify the environment, more and more river ecological reconstruction projects are included in the construction plan. At present, most of the common transformation methods are to demolish the existing revetment and rebuild new ecological revetment, but there are a series of disadvantages such as large negative impact on the surrounding environment, waste of resources, high energy consumption, and high cost. At the same time, due to the increasing shortage of land resources, the construction waste generated There is nowhere to place it.

重力式浆砌块石护岸是最古老的一种挡墙结构形式,因其料源丰富、形式简单、取材方便、施工简便,一直以来应用十分广泛。参见图1,图中给出的是现状浆砌块石重力式护岸,包括前排钢筋砼预制方桩10、后排钢筋砼预制方桩20、设置在前排钢筋砼预制方桩10和后排钢筋砼预制方桩20的顶端且与前排钢筋砼预制方桩10和后排钢筋砼预制方桩20固接的钢筋砼底板30、设置在钢筋砼底板30上的浆砌块石墙身40以及设置在浆砌块石墙身40的顶面上的压顶50。对于地势落差小、河道水不深、挡土高度小的平原地区,从经济实用层面来考虑,大多会选用重力式浆砌块石护岸结构。Gravity-type mortar block stone revetment is the oldest form of retaining wall structure. It has been widely used because of its rich material source, simple form, convenient material acquisition and convenient construction. Referring to Fig. 1, what provided in the figure is the existing grout block stone gravity revetment, including the front row of reinforced concrete prefabricated square piles 10, the rear row of reinforced concrete prefabricated square piles 20, the front row of reinforced concrete prefabricated square piles 10 and the rear The top of the row of reinforced concrete prefabricated square piles 20 and the reinforced concrete bottom plate 30 fixedly connected with the front row of reinforced concrete prefabricated square piles 10 and the rear row of reinforced concrete prefabricated square piles 20, and the mortar block stone wall body arranged on the reinforced concrete bottom plate 30 40 and the pressure top 50 that is arranged on the top surface of the mortar block stone wall body 40 . For plain areas with small terrain drop, low river water, and small retaining height, from the perspective of economics and practicality, gravity-type mortar block stone bank revetment structures are mostly used.

基于城市发展需求,需要对现状护岸进行生态化改造。大多数设计者通常是采用完全拆卸现状挡墙结构,取而代之以墙体材料为预制砼块体、生态石笼等生态景观效果好的护岸结构形式,在河湖生态化治理方面取得了一定的成效。但由于较多现状护岸尚在使用年限内,结构安全可靠,安全拆除重建既不经济也不环保,实施难度也大,缺点比较明显,亟需在现状护岸结构的基础上研究出利用现状护岸、仅进行局部拆除的生态化改造方案。Based on the needs of urban development, it is necessary to carry out ecological transformation of the current revetment. Most designers usually completely dismantle the existing retaining wall structure and replace it with prefabricated concrete blocks, ecological gabions and other revetment structures with good ecological landscape effects, which have achieved certain results in the ecological management of rivers and lakes. . However, because most of the current revetment is still within the service life, the structure is safe and reliable, safe demolition and reconstruction are neither economical nor environmentally friendly, and the implementation is also difficult, with obvious shortcomings. An ecological transformation plan with only partial demolition.

为此,申请人进行了有益的探索和尝试,找到了解决上述问题的办法,下面将要介绍的技术方案便是在这种背景下产生的。For this reason, the applicant has conducted useful explorations and attempts, and has found a solution to the above-mentioned problems, and the technical solutions to be introduced below are produced under this background.

为了使本实用新型实现的技术手段、创作特征、达成目的与功效易于明白了解,下面结合具体图示,进一步阐述本实用新型。In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

参见图2和图3,图中给出的是一种生态自净型景观护岸改造结构,包括前排桩100、后排桩200、设置在前排桩100和后排桩200的顶端且与前排桩 100和后排桩200固接的挡墙底板300以及设置在挡墙底板300上的挡墙墙身 400。前排桩100和后排桩200为C30钢筋砼预制方桩。挡墙底板300采用C30 钢筋混凝土制成。Referring to Fig. 2 and Fig. 3, what provides in the figure is a kind of ecological self-cleaning type landscape bank revetment reconstruction structure, comprises front row pile 100, rear row pile 200, is arranged on the top of front row pile 100 and rear row pile 200 and is connected with front row pile 100 and rear row pile 200. The retaining wall bottom plate 300 to which the row of piles 100 and the rear row of piles 200 are fixedly connected and the retaining wall body 400 arranged on the retaining wall bottom plate 300 . The front row of piles 100 and the rear row of piles 200 are C30 reinforced concrete prefabricated square piles. The bottom plate 300 of the retaining wall is made of C30 reinforced concrete.

挡墙墙身400被局部破拆至设计高程,设计高程通常是3.0m(约三层石料),高程3.0m~2.4m的挡墙墙身400的挡土侧约0.6m厚石料也需拆除,确保被破拆后的挡墙墙身400的墙顶宽度不小于0.5m,墙背斜率与未破拆的挡墙墙身一致;高程3.0m~2.6m的挡墙墙身400每延米拆除一块石料。破拆挡墙墙身400后,可以保证常水位时水、陆贯通。挡墙墙身400被局部破拆时所涉及的表面需采用1:3水泥砂浆对石缝进行抹平处理,以免影响挡墙墙身400耐久性。挡墙墙身400在破拆时所产生的石料无需外运,经去除砌筑砂浆并清洗后可作为墙后陆生梯台的挡土石,石缝中亦可生长植物,既与挡墙墙身400保持了风格的统一,也使每级植物生长平台的边界轮廓显得自然生动有趣。The wall body 400 of the retaining wall is partially demolished to the design elevation, which is usually 3.0m (about three layers of stone), and the stone materials about 0.6m thick on the retaining side of the wall body 400 with an elevation of 3.0m to 2.4m also need to be removed , to ensure that the width of the top of the wall body 400 of the demolished retaining wall is not less than 0.5m, and the slope of the wall back is consistent with that of the wall body that has not been demolished; the wall body 400 of the wall with an elevation of 3.0m to 2.6m is 400 meters per linear meter Remove a stone. After the wall body of the retaining wall is demolished for 400 degrees, it can ensure that the water and land are connected at a constant water level. When the wall body 400 of the retaining wall is partially demolished, the surface involved shall be smoothed with 1:3 cement mortar to avoid affecting the durability of the wall body 400 of the retaining wall. The stones produced during the demolition of the retaining wall body 400 do not need to be transported outside. After the masonry mortar is removed and cleaned, they can be used as retaining stones for the terrestrial terraces behind the wall. Plants can also grow in the stone crevices, which is compatible with the retaining wall. Body 400 maintains the unity of style, and also makes the boundary outline of each level of plant growth platform appear natural, vivid and interesting.

The water-facing side and the soil-retaining side are connected, and the width of the drainage groove 410 is 0.3m.

考虑河道一般具有行洪、排涝功能,本次改造不宜减小河道水面率、过水和蓄水能力,因此,不宜大范围改变墙前土坡坡率等重要参数,因而在河道堤岸的地面上位于挡墙墙身400的迎水侧面的前方设置有至少一级墙前水生平台,并在每一级墙前水生平台上种植水生植物,对河道水面率、过水和蓄水能力横断面几无影响。在本实施例中,墙前水生平台为两个,分别为第一级墙前水生平台510和第二级墙前水生平台520,第一级墙前水生平台510 的设计高程低于第二级墙前水生平台520的设计高程,具体地,第一级墙前水生平台510的高程为1.8m,第二级墙前水生平台520的高程为2.4m。第一级墙前水生平台510和第二级墙前水生平台520的平台填土坡度为1:10,可以种植不同耐水深度的水生植物。例如,第一级墙前水生平台510上种植的水生植物通常为耐水深度在0.8m~1m的水生植物,例如荷花、萍蓬草等;第二级墙前水生平台520上种植的水生植物通常为耐水深度在0.3m~0.6m的水生植物,例如再力花、黄菖蒲、慈菇等。Considering that the river generally has the functions of flood discharge and drainage, this reconstruction should not reduce the water surface rate, water flow and water storage capacity of the river. Therefore, it is not suitable to change important parameters such as the slope ratio of the soil in front of the wall on a large scale. Therefore, on the ground of the river embankment At least one level of aquatic platform in front of the wall is arranged in front of the water-facing side of the wall body 400 of the retaining wall, and aquatic plants are planted on the aquatic platform in front of each level of wall. no effect.
