Abstract
The utility model relates to the field of civil engineering construction, in particular to the construction field of an open caisson structure, and discloses a grouting pipe for lubrication of the open caisson structure. The grouting pipe for lubrication of the open caisson structure comprises an external grouting pipe body fixed on the outer wall of the open caisson structure. The grouting pipe for lubrication of the open caisson structure is characterized by further comprising an internal slipping grouting pipe body and sealing rubber sleeves, wherein the internal slipping grouting pipe body is sleeved with the external grouting pipe body, the two ends of the internal slipping grouting pipe body are open, a plurality of through holes are formed in the wall of the internal slipping grouting pipe body, and the sealing rubber sleeves are arranged at the two ends of the internal slipping grouting pipe body. Lips are arranged on the edges of the sealing rubber sleeves and are in interference fit with the inner wall of the external grouting pipe body. According to the structure, the position of the grouting section can be controlled at any time by moving the internal slipping grouting pipe body vertically in the grouting process, the phenomenon that grout is diffused unevenly in the grouting process is prevented, and the evenness of the lubrication grout injected between the outer wall of the open caisson structure and a soil body is ensured.
Description
Technical field
The utility model relates to the Construction of Civil Engineering field, especially designs the construction field of caisson structure.
Background technology
Dryly dig the method open caisson construction while running into the larger soil layer of the coefficient of friction resistance, due to soil layer frictional resistance, the phenomenon that can cause caisson structure to be difficult to sink, the degree of depth of open caisson is larger, and sinking will be more difficult; For overcoming the frictional resistance of soil layer, by caisson structure outside coating epoxy resin, utilize the smooth surface of epoxy resin to reduce the frictional resistance of open caisson outer wall and soil layer, then open caisson wall inside is respectively arranged to some Grouting Pipe shot lubrication slurries with the outside.Yet, when the frictional resistance between caisson structure and soil layer is excessive, easily cause the inhomogeneous situation of outer wall Grouting Pipe slurries injection, thereby affect the lubricant effect of caisson structure.
Summary of the invention
The purpose of this utility model is, provides the outside Grouting Pipe slip casting of a kind of assurance uniform novel slurry filling tubular structure, and in order to achieve the above object, the utility model is achieved in that
The lubricated Grouting Pipe of using of a kind of caisson structure, it comprises the outside Grouting Pipe be fixed on the caisson structure outer wall, it is characterized in that: also comprise and be placed in interior slip Grouting Pipe in outside Grouting Pipe, that offer some through holes on two-port opening and tube wall, and the seal rubber sleeve of being located at interior slip Grouting Pipe two-port place, the edge of described seal rubber sleeve is provided with the inwall interference fit of ，Chun limit, lip limit and outside Grouting Pipe.
The utility model adopts said structure, because the two ends of interior slip Grouting Pipe are provided with seal rubber sleeve, seal rubber sleeve is attached to outer Grouting Pipe inboard and is provided with the lip limit, when slurries inject, because of the effect lip limit of pressure, can be adjacent to the inboard of outer Grouting Pipe, during slip casting, move up and down the interior slip Grouting Pipe and just can control at any time the slip casting fragment position, the inhomogeneous diffusion of slurries while preventing slip casting, guarantee between caisson structure outer wall and the soil body to inject the uniformity of lubricating slurries.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of caisson structure.
The specific embodiment
As shown in Figure 1 and Figure 2, the lubricated Grouting Pipe of using of a kind of caisson structure, it comprises the outside Grouting Pipe 2 be fixed on caisson structure 1 outer wall, it is characterized in that: also comprise and be placed in interior slip Grouting Pipe 21 in outside Grouting Pipe 2, that offer some through holes 22 on two-port opening and tube wall, and the seal rubber sleeve 24 of being located at interior slip Grouting Pipe 21 two-port places, the edge of described seal rubber sleeve 24 is provided with the inwall interference fit of 25，Chun limit, lip limit 25 and outside Grouting Pipe 2.
The utility model adopts said structure, because the two ends of interior slip Grouting Pipe are provided with seal rubber sleeve, seal rubber sleeve is attached to outer Grouting Pipe inboard and is provided with the lip limit, when slurries inject, because of the effect lip limit of pressure, can be adjacent to the inboard of outer Grouting Pipe, during slip casting, move up and down the interior slip Grouting Pipe and just can control at any time the slip casting fragment position, the inhomogeneous diffusion of slurries while preventing slip casting, guarantee between caisson structure outer wall and the soil body to inject the uniformity of lubricating slurries.
