Description

Novel pipeline horse riding well

Technical Field

The utility model relates to a pipeline for rainwater and sewage pipe jacking construction in the fields of water environment comprehensive remediation and the like, in particular to a novel pipeline horse riding well.

Background

The pipe-jacking construction technology is a trenchless tunneling type pipe laying construction technology for municipal construction, and is very frequently applied to the fields of water supply, sewage treatment, pipe network pump stations, water environment comprehensive treatment and the like. In the pipe for pipe-jacking construction, an inspection well, namely a horse riding well, needs to be constructed in the middle of a pipe section of the pipe jacking based on the reasons of inspection, cleaning and the like of the pipe. At present, the construction of a common horse riding well has the following difficulties: firstly, the horse riding well is constructed, generally after pipe jacking is completed, which means that pipe jacking pipe joints connected with a horse riding well chamber cannot be processed in advance, so that the horse riding well is difficult to connect with a pipeline; secondly, the well chamber of the ordinary horse riding well usually has no bottom plate and is directly placed on the pipe joints of the push pipes, and in the construction process of the horse riding well, no matter the construction mode of obvious protection or immersed pipes is adopted, the well chamber is easy to collide with the pipe joints of the push pipes in the current situation in the hoisting process, and because the pipe joints of the push pipes at the lower part of the horse riding well need to be opened by adopting a physical mode, the possibility of crushing the pipe joints of the push pipes in the current situation is further increased. In the actual construction process, if the lower pipe-jacking joint is broken, the construction complexity and the construction cost are increased no matter the pipe joint is replaced or repaired; in addition, the problem of stress concentration already occurs at the position of the lower pipe joint, and because the common horsewell is not provided with a bottom plate and a foundation, the lower pipe joint of the jacking pipe directly bears the weight of the horsewell, is not uniformly stressed, and is also easy to break and crack in the running process of the pipeline; finally, the general horse riding well is not provided with a bottom plate, the lower part in the well chamber is the outer wall of the arc-shaped jacking pipe, so that inconvenience is brought to operation and maintenance personnel in the later operation and maintenance process of the pipeline, and silted up sundries are not easy to clean.

Therefore, it is necessary to design a novel horse riding well, and on the premise of ensuring construction convenience and safety, the risk of breakage of the pipe joints of the current situation push pipes at the lower part of the horse riding well is reduced, and the normal operation of later-stage pipelines is ensured.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art, reduce the risk of crushing the pipe joints of the push pipes under the horseback riding well under the condition of ensuring the construction convenience and safety, and ensure the normal operation of later-stage pipelines.

The purpose of the utility model is realized by the following technical scheme: the utility model provides a novel pipeline is ridden horse well, is including burying the push pipe pipeline section in basic soil layer underground, be provided with the trompil on the pipe wall of push pipe pipeline section, the surface of trompil with basic soil layer's upper surface parallel arrangement, basic soil layer's upper surface is provided with the bottom plate, the middle part of bottom plate be provided with the bottom plate trompil that push pipe pipeline section trompil is linked together, the upper end of bottom plate is provided with the well room that is linked together with the bottom plate trompil, the upper end of well room is provided with the roof, the middle part of roof is provided with the roof trompil that is linked together with the well room, the roof is linked together through the pit shaft of roof trompil and upper end setting, the top of pit shaft covers there is the well lid.

The aperture of the bottom plate opening is matched with the aperture of the top pipe section.

The well chamber is connected with the top plate and the bottom plate in a sealing way.

The well chamber is matched with the top plate and the bottom plate to be formed into one of a square shape or a round shape.

The well chamber is formed by one of a finished reinforced concrete well chamber or a cast-in-place reinforced concrete well chamber.

The foundation soil layer is made of plain concrete with a penetration function.

The utility model has the following beneficial effects: the pipeline horse riding well reduces the hidden danger that a horse riding well chamber collides with the current situation pipe jacking pipe section during construction to cause the pipe jacking pipe section to be broken in the construction process, enables the current situation pipe jacking pipe section to be stressed uniformly, prolongs the service life of the horse riding well, and compared with the traditional horse riding well, due to the fact that the bottom plate is arranged at the bottom, the hidden danger that the collision problem in the horse riding well hoisting process can be effectively solved, is more convenient for later-stage operation and maintenance, and can be applied to non-excavation pipe jacking engineering of urban rainwater, sewage and industrial sewage.
