Abstract
The utility model relates to a concrete pipe pile pumping pipe connection structure. The concrete pipe pile pumping pipe connection structure comprises a plurality of pumping pipes, and is creatively characterized in that flanges are respectively arranged at the ends of the pumping pipes, the adjacent pumping pipes are fixedly connected by bolts penetrating the flanges, a circular sealing groove is arranged on the end surface of the flange of one of two adjacent pumping pipes, and an O-shaped sealing ring is embedded in each circular sealing groove. The pumping pipes are connected by utilizing the flanges, and the connection structure is simple and reliable; the sealing rings are arranged among the flanges, so that the connection sealing property is improved, and leakage in pumping is avoided.
Description
Technical field
The utility model relates to a kind of concrete pipe pile pumping line, particularly a kind of concrete pipe pile pumping line linkage structure of simple in structure, good airproof performance.
Background technique
Along with the development of concrete technology, the technology of concrete pipe pile also reaches its maturity, and except being applied to industry, civil building, also is widely used in each field such as bridge, harbour, railway or hydraulic engineering.
Traditional pumping material pipe connecting structure is: adjacent material tube end arranges annular flange flange, pipe clamp is the anchor ear type structure, the anchor ear center has locating slot, during connection, anchor ear is buckled on the annular flange flange, annular flange flange embeds in the locating slot, is locked by anchor ear, and the C RunddichtringO is set in locating slot.The shortcoming of this kind structure is: sealing was poor when the pipe pressure was higher, and concrete easily oozes out from the joint, the material phenomenon occurred leaking.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of concrete pipe pile pumping line linkage structure of simple in structure, good airproof performance.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of concrete pipe pile pumping line linkage structure, comprise some pump feeding tubes, its innovative point is: the end of described pump feeding tube is provided with flange, the end face of flange of described pump feeding tube one end has annular seal groove, described annular seal groove is embedded with the O RunddichtringO, and the end face of flange of the pump feeding tube the other end is smooth flat; Described adjacent pump feeding tube connects by passing flange.
The utility model has the advantage of: the pump feeding tube utilizes flange to connect, and linkage structure is simple, reliable, and seal ring is set between flange, improves the connection sealing energy, occurs seepage when avoiding stock.
Description of drawings
Fig. 1 is the utility model concrete pipe pile pumping line linkage structure schematic representation.
Embodiment
As shown in Figure 1, comprise pump feeding tube 1, flange 2, bolt 3, seal groove 4, seal ring 5.
Said pump feeding tube 1 has some, is connected and fixed by linkage structure, is specially: be provided with flange 2 in the end of pump feeding tube 1, adjacent pump feeding tube 1 is connected and fixed by the bolt 3 that passes flange 2.
Flange 2 end faces of a pump feeding tube 1 have annular seal groove 4 in the adjacent pump feeding tube 1, and annular seal groove 4 is embedded with O RunddichtringO 5.
