Abstract
The utility model provides a super large bore cement pipe, relates to concrete duct, especially a stable in structure, super large bore cement pipe that the practicality is strong. The utility model discloses a super large bore cement pipe, this cement pipe of its characterized in that includes body, socket and bellmouth, and the socket sets up respectively at the body both ends with the bellmouth, and the socket outer wall is the positive step of second grade form, and second level step external conjugate diameter is less than the body external diameter, the bellmouth inner wall is the step phase -match of the anti - step of second grade form, this step and socket outer wall, the inside reinforced frame of having buried underground of body, socket first order step is rubber circle parcel for the lateral wall, and second level step is socket steel loop parcel for the lateral wall, be provided with the bellmouth steel loop on the inner wall of bellmouth step. The utility model discloses a super large bore cement pipe designs the science, and is rational in infrastructure, and convenient to use at the inside reinforced frame that sets up of cement pipe body, sets up the steel loop on socket and bellmouth, effectively increased the intensity of cement pipe self, locates still to be provided with the rubber circle at the socket simultaneously, improves the seal.
Description
Technical field
The utility model relates to concrete duct, especially a kind of structural stability, practical super large caliber cement pipe.
Background technique
Concrete duct is also known as concrete reinforced pipe, and it can build drainage pipeline in base as urban construction, can sewer, flood control draining, and the water inlet used in some special factories and miness and farmland motor-pumped well.Generally be divided into: flat mouth reinforced concrete cement pipe, flexible tongue and groove reinforced concrete cement pipe, joint socket reinforced concrete cement pipe, F shaped steel bellmouth cement pipe, flat mouth cover ring interface cement pipe, tongue and groove cement pipe etc.At present, conventional cement pipe bore scope is between 300mm-3000mm, and the cement pipe of 3000mm bore is in the field of business is also referred to as heavy caliber cement pipe; And bore is more than 3000mm, what reach 4000mm is then called super large caliber cement pipe, and because caliber is larger, the hydraulic pressure of cement pipe inside is also larger, and in normal using process, the hydraulic pressure of its inside can reach 2kg/cm
2, therefore all have higher requirement to the seal of cement pipe internal intensity and interface.
Due to the defect of existing cement pipe structure, its inside and interface structure all can not bear the requirement of hydraulic pressure, and therefore, the maximum heavy caliber cement pipe can only accomplishing 3000mm of its bore of existing cement pipe, cannot make the super large caliber cement pipe of 4000mm.
Summary of the invention
The problem being exactly its inside of existing cement pipe and interface structure and can not meeting super large caliber cement pipe hydraulic demand to be solved in the utility model, provides a kind of structural stability, practical super large caliber cement pipe.
Super large caliber cement pipe of the present utility model, it is characterized in that this cement pipe comprises body, socket and bellmouth, socket and bellmouth are separately positioned on body two ends, and receptacle wall is that secondary is just step-like, and second level step outer diameter is less than outer tube diameter; Bellmouth inwall is that secondary is anti-step-like, and the step of this step and receptacle wall matches; Tubular body is embedded with reinforced frame; Socket first order mesa sidewall rubber ring wraps up, and second level mesa sidewall socket steel ring wraps up; The inwall of bellmouth step is provided with bellmouth steel loop.
Described socket step is also provided with cushion rubber platform, and rubber ring is placed on cushion rubber platform.
Described reinforced frame is double steel bar structure, and every layer of reinforcing bar, in " well " font, is welded with supporting frame between two-layer reinforcing bar, keeps the spacing between the intensity of reinforced frame and two-layer reinforcing bar by supporting frame.
Bury the reinforced frame of double steel bar support at the tubular body of super large caliber cement pipe underground, effectively can improve the intensity of body, can better disperse by the bar construction of " well " font the pressure bearing hydraulic pressure; Use rubber ring and socket steel ring structure at the socket of cement pipe, not only can increase the intensity of socket, seal when cement pipe connects can also be improved, avoid revealing in joint.
Super large caliber cement pipe of the present utility model, design science, rational in infrastructure, easy to use, reinforced frame is set at cement pipe tubular body, socket and bellmouth arrange steel loop, effectively increase the intensity of cement pipe self, be also provided with rubber ring at spigot simultaneously, improve seal.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, body 1, socket 2, bellmouth 3, rubber ring 4, socket steel ring 5, bellmouth steel loop 6.
Embodiment
Embodiment 1: a kind of super large caliber cement pipe, comprises body 1, socket 2 and bellmouth 3, and socket 2 and bellmouth 3 are separately positioned on body 1 two ends, and socket 2 outer wall is that secondary is just step-like, and second level step outer diameter is less than body 1 external diameter; Bellmouth 3 inwall is that secondary is anti-step-like, and the step of this step and socket 2 outer wall matches; Body 1 inside is embedded with reinforced frame; Socket 2 first order mesa sidewall rubber ring 4 wraps up, and second level mesa sidewall socket steel ring 5 wraps up; The inwall of bellmouth 3 step is provided with bellmouth steel loop 6.This socket 2 step is also provided with cushion rubber platform, and rubber ring 4 is placed on cushion rubber platform.Reinforced frame is double steel bar structure, and every layer of reinforcing bar, in " well " font, is welded with supporting frame between two-layer reinforcing bar, keeps the spacing between the intensity of reinforced frame and two-layer reinforcing bar by supporting frame.
Bury the reinforced frame that double steel bar supports in body 1 inside of super large caliber cement pipe underground, effectively can improve the intensity of body 1, can better disperse by the bar construction of " well " font the pressure bearing hydraulic pressure; Use rubber ring 4 and socket steel ring 5 structure at the socket 2 of cement pipe, not only can increase the intensity of socket 2, seal when cement pipe connects can also be improved, avoid revealing in joint.
