Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to the technical field of embankment retaining walls, and specifically is a reinforced retaining wall structure, which can convert high-water content engineering mud into a reinforced earth retaining wall backfill. Background Art
[0002] During the construction of some large projects, a large amount of waste engineering mud is generated and needs to be treated urgently. This type of mud has the characteristics of high water content, high compressibility, low permeability and low bearing capacity. At present, the main way to dispose of this mud is to pile it up in the project yard, which not only occupies a large amount of land resources, but also easily causes secondary pollution to the soil. With the continuous increase in mud production, the land resources used as yards are becoming increasingly scarce. Therefore, in order to solve the problem of shortage of yard resources, an effective means of converting engineering mud into engineering filler resources is urgently needed.
[0003] Reinforced earth retaining wall is a commonly used retaining structure in retaining wall engineering. Its main working principle is to improve the overall stability of the retaining wall structure by using the friction between the reinforcing material and the soil filling behind the wall. For traditional reinforced earth retaining wall, the filling behind the wall requires easy filling and compaction, so coarse-grained soil such as sand, gravel, crushed stone and so on with good gradation is generally used; while engineering mud contains a large amount of fine-grained soil such as clay and silt, and has high water content and extremely low strength, so it cannot be directly used as the filling behind the reinforced earth retaining wall.
[0004] Therefore, it is necessary to set up certain installation structures and equipment to enable the high-water content engineering mud to be dehydrated / consolidated / solidified in situ behind the wall, and convert the waste engineering mud into building material resources as the backfill of the reinforced earth retaining wall, thereby forming a new retaining wall structure. Utility Model Content
[0005] The purpose of the utility model is to provide a new type of reinforced retaining wall structure, which can quickly dehydrate / consolidate / solidify the engineering mud with high water content in situ behind the wall, so as to convert the waste engineering mud into building material resources as the backfill of the reinforced earth retaining wall. The purpose of the utility model is achieved through the following technical solutions:
[0006] A reinforced retaining wall structure is arranged in front of a highway embankment, comprising a bottom foundation and at least one layer of retaining structure above it: the bottom foundation comprises a concrete foundation in the front and a compacted soil layer in the rear; the retaining structure comprises a retaining wall panel and a horizontal drainage board and a mud cement mixture layer arranged behind the retaining wall panel and in front of the highway embankment, the mud cement mixture layer of each retaining structure is laid on the horizontal drainage board of the current layer; the upper end of the mud cement mixture layer of each retaining structure is flush with the upper end of the retaining wall panel of the current layer; the retaining wall of the first retaining structure is provided with a plurality of retaining walls, each of which ... The earth wall panels are arranged on a concrete foundation, and the horizontal drain boards of the first retaining structure are arranged on the compacted soil layer; the retaining wall panels of other retaining structures are arranged on the retaining wall panels of the next layer, and the horizontal drain boards are arranged on the mud cement mixture layer of the next layer; the horizontal drain boards are perpendicular to the retaining wall panels, and the surfaces of the horizontal drain boards are provided with grooves and convex patterns which are perpendicular to the retaining wall panels and arranged parallelly and alternately, and a drain pipe is arranged in each groove; the pipe wall of the drain pipe is provided with a through hole, and the front end of the drain pipe is connected to a vacuum pump through a pumping pipe.
[0007] Furthermore, the compacted soil layer is 0.1 m thick, and the mud cement mixture layer is 0.4-0.8 m thick.
[0008] Furthermore, the drain pipe is fixed in the groove of the horizontal drain board by a bracket or a fixing clamp.
[0009] Furthermore, the horizontal drain board is a plastic drain board, and the convex patterns of the horizontal drain board are formed by arranging conical protrusions or cylindrical protrusions made by stamping.
[0010] Furthermore, each layer of the horizontal drainage board is provided with more than 3 drainage pipes.
[0011] Furthermore, the upper and lower relative drainage pipes in each layer are connected to a main pipe through a suction pipe and then connected to a vacuum pump.
[0012] Principle of the utility model: The utility model uses a horizontal drain board to replace the commonly used geogrid. The drain pipes arranged on the horizontal drain board are connected to the vacuum equipment to dehydrate the engineering mud, so that the mud can be quickly consolidated into soil and wrapped around the drain board, so that the drain board and the soil can effectively transfer the load and work together. The horizontal drain board not only dehydrates the mud and reduces its moisture content, but also replaces the geogrid to reinforce the backfill after the mud is consolidated.
[0013] Beneficial effects of the utility model:
[0014] The reinforced retaining wall structure of the utility model can utilize the discarded engineering mud as retaining wall filler for resource utilization while ensuring the stability of the reinforced retaining wall structure, thus avoiding the land resource occupation and pollution problems caused by the traditional landfill method; at the same time, since there is no need to purchase additional natural soil materials for use as retaining wall filler, the cost of the reinforced earth retaining wall is reduced.
