Embodiments of the present invention and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The terminology of the invention is explained.
River course in intensive house area: coastal areas and developed areas of plain river networks often have dense population, and civil houses face the river, so that the river channels are narrow, surrounding houses are dense, the in-out traffic is difficult, and the conventional construction conditions are basically not provided.
Dirt interception pipeline 6: because the close distribution of the river-facing civil houses often causes serious pollution to the surrounding river network water environment because the sewage along the river residential areas is directly discharged into the river, the above areas often need to be constructed by intercepting the sewage network pipes along the river.
River course shore protection: the river bank protection of the house dense area river channel is solved by optimizing the hydraulic structure, the bank protection type can ensure the stable and safe protection of the surrounding dense building group in the river bank construction process, the river bank protection construction can be effectively carried out, and meanwhile, the laying of the river intercepting sewage pipeline 6 is met.
The existing two technologies are:
the construction method adopts a rotary-digging cast-in-place pile wall-mounted wall-protecting mode, ensures the stability and safety of the construction formed by two sides in the process of river channel bank slope excavation, adopts cast-in-situ large-diameter reinforced concrete cast-in-place piles as a bearing structure for bank slope anti-slip, and adopts a thin-wall reinforced concrete wall-mounted wall arranged outside a waterside pile body as a connecting member for anti-impact retaining, thereby forming an integral inter-pile wall 3-protecting structure.
Adopting a prefabricated sheet pile shore protection mode, wherein the shore protection mode is a closely arranged prefabricated [ V-shaped or U-shaped ] reinforced concrete sheet pile structure, closely driving prefabricated piles into the river bank side through a high-frequency vibrating hammer to form a closely arranged shore protection structure, and pouring a through reinforced concrete crown beam on the pile top after the construction of the closely arranged piles is completed to ensure the structural integrity and strength of the closely arranged piles; the closely-arranged prefabricated sheet pile bank protection structure can ensure that the river bank slope is reinforced in a permanent-face combination mode in the construction process.
The disadvantages of the two prior art techniques described above:
the unit investment is larger: the wall-hanging wall type revetment of the rotary-digging bored concrete pile is required to be advanced by a large-scale rotary-digging drilling machine, and the unit linear meter unit price of the river revetment of the reinforced concrete pile body is 1.5-2.5 ten thousand; when the closely arranged prefabricated sheet piles are adopted for bank protection, large-scale vibration hammering equipment is required, and the high-frequency hammering can be used for entering soil in place, so that the strength of the prefabricated sheet piles is generally higher than that of C60 high-strength concrete, the manufacturing cost is high, and the unit price per linear meter reaches 1.2-1.6 ten thousand.
The construction site is high in requirement: the construction adopting the two shore protection types requires large mechanical equipment to enter and exit the construction passageway, the width of the passageway is 4.5m, and the requirements of the site are high, so that the construction conditions are difficult to meet under the conditions that the population is dense in coastal developed areas and the civil houses are built in the river.
The influence on the periphery is larger in the construction process: the two shore protection types all need large-scale machine implementation in the construction process, and larger vibration exists in the pile body implementation process, so that the influence on the surrounding dense houses is larger and certain irreversible damage is easy to occur.
The attached sewage interception pipeline 6 needs to consider a new arrangement space and an excavation supporting mode.
Example 1
In order to solve the above-mentioned drawbacks, as shown in fig. 1 and 2, the present embodiment provides a river revetment considering the arrangement of the sewage interception pipeline 6, which comprises an inner steel pipe pile assembly 1, an outer steel pipe pile assembly 2, an inter-pile wall 3, a concrete bottom plate 4 and a concrete top plate 5.

Because the stress member is a small-diameter steel pipe pile, only small downward pressure is needed in the piling process, large mechanical access is not needed, large vibration is not generated in the construction process, and the influence on the surrounding formed buildings is minimal.
Preferably, in order to increase the stability of the same construction, the concrete bottom plate 4 is set horizontally, and the lower end of the inter-pile wall 3 is fixedly connected with the middle line of the upper side surface of the concrete bottom plate 4; the concrete top plate 5 is horizontally arranged, and the upper end of the inter-pile wall 3 is fixedly connected with the middle line of the lower side surface of the concrete top plate 5.
