MASHDPE inspection well

Abstract

The MASHDPE inspection well comprises an MASHDPE well body and a pipe joint, the MASHDPE well body is in an eggshell shape, the middle of the MASHDPE well body protrudes outwards in an arc mode, the top of the MASHDPE well body is provided with an equal-diameter well opening, and the bottom of the MASHDPE well body is an equal-diameter well bottom; the two ends of the pipe connector are integrated pipelines, the inner diameter of the well bottom is larger than that of the pipe connector, the well bottom and a part of the MASHDPE well body are connected with the pipe connector in a crossed mode, and the inner side of the bottom wall of the well bottom coincides with the horizontal symmetry plane of the pipe connector. The MASHDPE well body is in an eggshell shape, and compared with a cylindrical MASHDPE well body, the MASHDPE well body is higher in pressure resistance and not prone to deformation. When the ditches are excavated, the MASHDPE well body is not grounded, the bottoms of the MASHDPE well bodies are similar to conical structures, and the ditches are originally narrow in lower parts and wide in upper parts, so that the bottoms of the ditches do not need to be widened independently.

Description

Technical Field

[0001] The utility model relates to the technical field of pipes, in particular to a MASHDPE inspection well. Background Art

[0002] Inspection wells are used for inspection purposes in series with large-diameter buried pipelines. Concrete masonry was previously used, but this method was material-intensive and inefficient. Now, many companies are using prefabricated MAS (Magic Angle Spinning) HDPE (High-Density Polyethylene). (MASHDPE is a polymer material that has been specially processed by spinning high-density polyethylene at a magic angle (54.70°) to the vertical to eliminate or reduce some of the inherent spectral properties of solid matter.) The structure is similar to that of a concrete inspection well, with a cylindrical shape and pipe fittings installed on both sides of the wall near the bottom. The trench is typically V-shaped during excavation, with the bottom narrowest, generally sufficient for pipe installation. However, the inspection well has a wide bottom, necessitating the trench bottom be widened, resulting in a separate, wider trench for the inspection well. Furthermore, MASHDPE is less rigid than concrete, and its straight cylindrical shape easily deforms under external soil pressure. Simply increasing the wall thickness would undoubtedly increase costs. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a MASHDPE inspection well which does not require widening of the trench for buried pipelines during installation and has stronger deformation resistance.

[0004] The technical solution of the utility model is:

[0005] A MASHDPE inspection well comprises a MASHDPE well body and a pipe joint. The MASHDPE well body is eggshell-shaped, with an outward arc-shaped bulge in the middle, a wellhead of equal diameter arranged on the top, and a well bottom of equal diameter arranged on the bottom. Both ends of the pipe joint are integral pipes, the inner diameter of the well bottom is larger than the inner diameter of the pipe joint, the well bottom and part of the MASHDPE well body are cross-connected with the pipe joint, and the inner side of the bottom wall of the well bottom coincides with the horizontal symmetry plane of the pipe joint.

[0006] Furthermore, a plurality of circles of transverse reinforcing ribs or vertical reinforcing ribs are provided along the outer periphery of the MASHDPE wellbore in a protruding manner.

[0007] Furthermore, the inner diameter of the well bottom is 16 cm to 20 cm larger than the inner diameter of the pipe joint.

[0008] Furthermore, a stainless steel support ring is embedded on the inner side of the wellhead.

[0009] The utility model is beneficial in that:

[0010] The present invention improves the MASHDPE wellbore. The MASHDPE wellbore is eggshell-shaped, which has stronger pressure resistance and is less prone to deformation than cylindrical wellbores. Furthermore, the diameter of the bottom of the eggshell-shaped MASHDPE wellbore is reduced. The wellbore bottom and part of the MASHDPE wellbore are connected to the pipe joint, and the inner side of the bottom wall of the wellbore coincides with the horizontal symmetry plane of the pipe joint. This allows the MASHDPE wellbore to have a conical bottom structure when excavating a trench. Since trenches are narrow at the bottom and wide at the top, there is no need to widen the trench bottom separately. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0015] like Figure 1-2 As shown:

[0016] A MASHDPE inspection well includes a MASHDPE well body 1 and a pipe joint. The MASHDPE well body 1 is eggshell-shaped, with an outward arc-shaped bulge in the middle, a wellhead 2 of equal diameter arranged on the top, and a well bottom 3 of equal diameter arranged on the bottom; both ends of the pipe joint are integrated pipes, the inner diameter of the well bottom 3 is larger than the inner diameter of the pipe joint, the well bottom 3 and part of the MASHDPE well body 1 are connected to the pipe joint, and the inner side of the bottom wall of the well bottom 3 coincides with the horizontal symmetry plane of the pipe joint.

[0017] The present invention improves the MASHDPE wellbore 1. The MASHDPE wellbore 1 is eggshell-shaped, which has a stronger pressure resistance and is less prone to deformation than a cylindrical wellbore. Moreover, the bottom diameter of the eggshell-shaped MASHDPE wellbore 1 is reduced, and then the well bottom 3 and part of the MASHDPE wellbore 1 are connected to the pipe joint. The inner side of the bottom wall of the well bottom 3 coincides with the horizontal symmetry plane of the pipe joint. In this way, when the trench 5 is excavated, since the MASHDPE wellbore 1 is not grounded, the bottom is similar to a cone-shaped structure, and the trench 5 is originally narrow at the bottom and wide at the top, there is no need to widen the bottom of the trench 5 separately (see Figure 2 a), which can greatly reduce the workload, while the existing joint structure requires a separate widening process for the part where the inspection well is installed, and the corresponding part requires a separate excavation of a wider trench 5 (see Figure 2 b).

[0018] In order to further increase the pressure resistance, several circles of horizontal or vertical reinforcement ribs 11 can be set along the outer periphery of the MASHDPE well body 1. The position of the well bottom 3 is mainly to facilitate a person's two feet to straddle. The inner diameter of the well bottom 3 is 16cm-20cm larger than the inner diameter of the pipe joint. In this way, there will be two symmetrical platforms with a maximum width of 8-10cm at the well bottom 3, which is sufficient for an adult's feet to straddle stably.

[0019] The MASHDPE well body 1 is eggshell-shaped, so it tends to disperse stress toward both ends, which is why it has strong compressive resistance. However, the wellhead 2 also needs to be covered. The wellhead 2 is not closed, and a stainless steel support ring 21 can be embedded on the inside of the wellhead 2 to avoid deformation here and prevent the cover from getting stuck.

[0020] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
