Abstract
The utility model relates to a convex socket steel loop concrete pushing pipe and consists of a steel socket, a cylindrical steel reinforcement framework and a concrete pipe core. The steel socket is fixed and arranged on one end of the concrete pipe core and the cylindrical steel reinforcement framework is coaxially embedded inside the concrete pipe core. The utility model is characterized in that a socket steel loop is coaxially fixed and arranged on the exterior wall of the socket end of the concrete pipe core, and the diameter of the exterior wall of the socket steel loop is larger than the diameter of the exterior wall of the concrete pipe core socket, thus forming a groove radially between the socket steel loop and the concrete pipe core. The convex socket steel loop concrete pushing pipe has simple integral structure as well as scientific and reasonable design, which is a convex socket steel loop concrete pushing pipe with a firm socket.
Description
Technical field
The utility model relates to concrete plug, especially a kind of concrete ceiling coil for steel ring with extrusion type insertion opening.
Background technique
In concrete plug, concrete ceiling coil is used comparatively extensive, especially under the occasion of operation of can not slotting.Mainly being configured to of present concrete ceiling coil: concrete pipe in-core setting-in Framework Of Steel Reinforcement pipe cage, this Framework Of Steel Reinforcement pipe cage is to be installed by bearing rod by two coaxial cylindrical reinforcement frames to form, concrete tube core one end installs the steel bellmouth, its socket end forms for the cast of concrete one, though this kind concrete ceiling coil can carry out jacking construction, but still have following defective: concrete tube core socket end is the concrete one-time cast-forming, damaged in the collision of jacking construction easily, cause the generation of spillage phenomenon, the process and the construction quality of influence construction.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, the concrete ceiling coil for steel ring with extrusion type insertion opening that socket is firm.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of concrete ceiling coil for steel ring with extrusion type insertion opening, constitute by steel bellmouth, cylindrical reinforcement frame pipe cage and concrete tube core, the steel bellmouth is packed in an end of concrete tube core, the coaxial concrete pipe in-core that is embedded in of cylindrical reinforcement frame pipe cage, it is characterized in that: at the coaxial socket steel ring that installs of concrete tube core socket end outer wall, the outer diameter of this socket steel ring makes between itself and the concrete tube core greater than concrete tube core socket outer diameter and forms a groove diametrically.
And described cylindrical reinforcement frame pipe cage is to be formed by two coaxial coaxial installing by bearing rod of cylindrical reinforcing bar cage.
And described cylindrical reinforcement frame is cylindrical reinforcing bar cage.
And described cylindrical reinforcing bar cage is installed by circumferential reinforcement and longitudinal steel bar and forms.
Advantage of the present utility model and beneficial effect are:
1. the coaxial socket steel ring that installs of concrete tube core socket end outer wall of this concrete ceiling coil for steel ring with extrusion type insertion opening, can effectively avoid in tubing jacking construction process owing to the destruction of collision tubing socket end, reduced the incidence rate of spillage phenomenon, construction progress and construction quality have been improved, and the outer diameter of this socket steel ring is greater than concrete tube core socket outer diameter, the outer wall of itself and concrete tube core projection forms a groove, O-ring seal is installed in this groove, make that cushion rubber is not easy to be distorted in the jack-in process, thereby improved construction quality.
2. the concrete pipe in-core of this concrete ceiling coil for steel ring with extrusion type insertion opening is embedded with Framework Of Steel Reinforcement pipe cage, and the number of plies of this Framework Of Steel Reinforcement pipe cage can be designed as multilayer, has strengthened this tubing opposing external pressure weight bearing power.
3. the utility model overall structure is very simple, and design science is reasonable, is the firm concrete ceiling coil for steel ring with extrusion type insertion opening of a kind of socket.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A portion enlarged diagram of Fig. 1.
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
This concrete ceiling coil for steel ring with extrusion type insertion opening, by steel bellmouth 7, cylindrical reinforcement frame pipe cage and concrete tube core 3 constitute, the steel bellmouth is packed in an end of concrete tube core, the coaxial concrete pipe in-core that is embedded in of cylindrical reinforcement frame pipe cage, this cylindrical reinforcement frame pipe cage is by two coaxial coaxial cylindrical reinforcement frame pipe cage type formulas that are welded by bearing rod 6 of cylindrical reinforcing bar cage that are welded by circumferential reinforcement 4 and longitudinal steel bar 5, (shown in the present embodiment accompanying drawing), this cylindrical reinforcement frame also can be the cylindrical reinforcing bar cage of individual layer, wherein at the coaxial socket steel ring 1 that installs of concrete tube core socket end outer wall, and the outer diameter of this socket steel ring is greater than concrete tube core socket outer diameter, the outer wall of itself and concrete tube core projection forms a groove 2, in this groove O-ring seal can be installed, the bellmouth when making mutual installation the and the socket of adjacent push pipe have better joint water closure, even under the situation of foundation settlement, socket steel ring can ensure effectively that also concrete tube core socket is not damaged, improve the seal of whole pipeline, prevented inside and outside water body UNICOM.
