Description

Inspection chamber component

Technical Field

The present disclosure relates to a component of an inspection chamber, and methods of producing the same.

Background

The examination room is often placed underground (ground boring ground water) containing groundwater. Therefore, they are exposed to groundwater pressure for a long time. Such exposure may eventually lead to a situation where the functional properties of the examination room are negatively affected. In general, it is desirable to increase the lifetime of the examination room.

There is a need for an inspection chamber and/or inspection chamber components that address at least one of the above-mentioned disadvantages. There is also a need for a method for producing the inspection chamber and the inspection chamber components.

Embodiments are defined by the following claims.

Disclosure of Invention

One aspect of the present disclosure relates to an inspection chamber component for placement underground containing groundwater. The component includes a cavity for receiving groundwater and having a cavity shape. The shape is not particularly limited. It is critical that groundwater can flow into and out of the chamber. The cavity is defined in part by a cavity wall for retaining groundwater in the cavity. The chamber wall is configured to resist groundwater pressure. The inspection chamber component further comprises a reinforcement member for providing additional rigidity for maintaining the shape of the circumference of at least a portion of the chamber wall.

The shape of the circumference, in particular of at least a portion of the cavity wall, is maintained for a longer time as the reinforcement member provides additional rigidity to the examination chamber component. This increases the lifetime of the components of the inspection chamber. The circumference may be the circumference of the entire chamber wall, or it may be the circumference of a portion of the chamber wall, such as the circumference of a dome-shaped portion of the chamber wall.

When the portion of the cavity wall belongs to the entire cavity wall, the reinforcing member is not part of the cavity wall. However, for other embodiments, i.e., when the portion of the cavity wall belongs to less than the entire cavity wall, i.e., a "real" portion of the cavity wall (e.g., belongs to a dome-shaped portion of the cavity wall), the reinforcing member may also be wholly or partially part of the cavity wall itself.

The configuration of the cavity receiving groundwater is understood to be the configuration in which the reinforcement members are to be arranged in spite of the presence. In other words, groundwater may thus circulate between the chamber and the outside of the exam chamber component. The reinforcing member does not block the passage of groundwater into and out of the chamber. Thus, the groundwater pressure inside the chamber filled with groundwater (when the exam room component is placed underground containing groundwater) is substantially the same as the groundwater pressure outside the component. Preferably, therefore, the reinforcing member is asymmetrically exposed to the groundwater pressure. This increases its lifetime. In addition, the cavity wall maintains its role as an important pressure barrier for resisting groundwater. This increases the lifetime of the components of the inspection chamber.

The inspection chamber component is preferably a pedestal (focusing) and/or base (base) component of the inspection chamber. When the inspection chamber is placed in position for use, the inspection chamber is oriented such that it rests on the base and/or base components (i.e., the inspection chamber components). Preferably, during use of the components of the inspection chamber, the chamber is oriented such that groundwater entering the chamber is in contact with the chamber walls, such that the chamber walls prevent further rising of groundwater.

The reinforcement member is preferably configured to increase the stiffness of the cavity wall. However, alternatively or in addition, the reinforcement member can be configured to increase the stiffness of any other portion of the exam chamber component, such as a sidewall or base component connected directly or indirectly to the chamber wall.

Preferably, the chamber wall comprises at least one dome-shaped portion. The dome-shaped portion is particularly suitable for resisting the pressure of groundwater. The tension in the wall resulting from the applied pressure is particularly evenly distributed. The entire chamber wall may be comprised of one dome-shaped section.

According to some embodiments, the cavity wall and the reinforcing member are integrally formed. In other words, the cavity wall and the reinforcement are continuously connected, i.e. they are made in one piece. Therefore, the efficiency of producing the components of the inspection chamber can be improved. Indeed, the chamber components may also be integrally formed with any other components of the chamber. The entire examination room including the components may, but need not, be formed in one piece.

According to some embodiments, the chamber wall comprises a plurality of dome-shaped portions. The term "plurality" means more than two.

Preferably, the cavity wall comprises a central dome-shaped portion surrounded by a plurality of concave and/or dome-shaped portions. This wall form is particularly advantageous since the surrounding concave and/or dome-shaped sections may increase the rigidity of the circumference of the central dome-shaped section. In particular, this arrangement improves the frangible connection area between the single dome-shaped portion and the side wall of the base component, which may be present if the cavity wall is constituted by a single dome-shaped portion. Thus, the durability of the central dome-shaped section, in particular with respect to the resistance to deformation (shape deformation), may be higher than a similar durability of a chamber wall consisting of one dome-shaped section.

According to some embodiments, the component further comprises a side wall, and at least one surrounding concave and/or dome-shaped portion is located between and connects the side wall and the central dome-shaped portion. This is advantageous because of the improved durability, particularly at the region between the side walls and the central dome-shaped portion. Preferably, all of the surrounding concave and/or dome-shaped portions are located between and connect the side walls and the central dome-shaped portion.

Preferably, the central dome-shaped portion is larger than the respective surrounding concave and/or dome-shaped portions. According to some embodiments, the central dome-shaped portion is larger than the sum of all surrounding concave and/or dome-shaped portions.

The reinforcing member may comprise at least one surrounding concave and/or dome-shaped portion, or may comprise all surrounding concave and/or dome-shaped portions. In other words, the reinforcement member may be a portion of the cavity wall. In this case, the portion of the cavity wall referred to is not the entire cavity wall itself, but rather a "real" portion thereof, with respect to the additional rigidity for maintaining the shape of the circumference of the cavity wall. The circumference of the portion of the chamber wall whose shape is maintained may then be, for example, the circumference of the central dome-shaped portion.

According to a preferred embodiment, the maximum width (a) of each surrounding concave and/or dome-shaped portion is larger than the maximum thickness (t) of the cavity wall. "maximum width" refers to the width of the cavity of the portion that is configured to receive a fluid, such as groundwater. This further increases the resistance to pressure-induced deformation and thus increases the lifetime of the components of the inspection chamber.

Preferably, at least one dome-shaped portion has the shape of a portion of a sphere. For the central dome-shaped portion (if present), a shape with a portion of a sphere is particularly preferred. Alternatively, the shape may resemble the shape of a portion of a sphere. For example, the shape may include polygonal portions that together approximate the shape of a portion of a sphere. According to some embodiments, all of the dome-shaped portions have the shape of a portion of a sphere (or a "similar" shape). The shape of a portion of the sphere (or a shape approximating this shape) in particular increases the lifetime of the components of the examination chamber, for example, because the tension forces resulting from the applied pressure are particularly evenly distributed.

The cavity wall is preferably at least partially concave or hollow shaped.

The reinforcement member may comprise (or consist of) a reinforcement plate that is connected to another portion of the examination chamber component. For example, the reinforcement member may comprise a reinforcement plate and additionally comprise a portion or portions of the cavity wall.

The reinforcing plate may have a substantially flat shape, but may also have a different shape, for example the shape of a portion of a sphere. The reinforcing member may also have reinforcing members such as reinforcing ribs (stiffening ribs) thereon.

The use of reinforcing plates as additional reinforcing members is particularly useful when the inspection chamber component is to be used at deeper groundwater levels, for example between 3 and 5 metres. The chamber walls can also provide sufficient rigidity without additional reinforcement plates when the inspection chamber components are used at water levels of 3 meters or less.

According to some embodiments, the stiffener plate is connected to another portion of the inspection chamber component by a weld. The inspection chamber component may include a sidewall, and the reinforcement plate may be connected to the sidewall via a weld.

According to some embodiments, the reinforcing plate comprises an opening configured to pass fluid through the reinforcing plate. The reinforcing plate preferably comprises a plurality (i.e. more than two) of such openings. This makes it possible to achieve a configuration of the cavity to receive fluids such as groundwater (despite the presence of the reinforcing member).

The inspection chamber component is preferably configured to allow fluid to flow into and out of the chamber along one or more surrounding concave and/or dome-shaped portions. This may be achieved, for example, by matching the position of the surrounding concave and/or dome-shaped portions with openings in the reinforcing plate. In particular, only one, two, several or all surrounding concave and/or dome-shaped portions may allow fluid communication. In other words, each surrounding concave and/or dome-shaped portion may be understood to constitute an "opening" or a "closed pocket". Additionally, or alternatively, the reinforcing plate may, for example, not extend to the extent of covering the surrounding concave and/or dome-shaped portions. In other words, the reinforcing plate may be connected to the cavity wall at a location between the central dome-shaped portion and the surrounding concave and/or dome-shaped portions. This connection may be, for example, one or several welds, and may not prevent fluid communication between a "central cavity" defined between the central dome-shaped member and the reinforcing plate, and one or several "peripheral cavities" defined at least in part by the surrounding concave and/or dome-shaped members.

The reinforcement plate and/or the chamber wall may be provided with at least one reinforcement rib. This further increases the stiffness, which additionally increases the lifetime of the components of the inspection chamber.

The inspection chamber component can further comprise a plate, wherein the chamber wall is a chamber-facing wall of the plate. The plate may, for example, be curved to conform to the shape of a portion of a sphere or the like, i.e., "approximate" shape, e.g., including polygonal portions that collectively approximate the shape of a partial sphere-like (partially spherical-like) shape.

According to some embodiments, the maximum height (h) of the central dome-shaped portion is equal to or greater than 2% of the maximum width (d) of the profile of the central dome-shaped portion (h/d ≧ 0.02), wherein the maximum height is defined as the maximum of the shortest distance between a point on the cavity wall and the surface of the profile comprising the central dome-shaped portion.

The maximum width of the profile of the central dome-shaped portion is typically the diameter of a circular perimeter profile (surrouding contourer). The "maximum height of the cavity" may be the maximum distance from a surface containing a contour circumference (a spherical) to a point on a sphere, a portion of which constitutes the shape of the cavity wall.

The maximum angle a between points on the contour may be equal to or less than 90 °, the angle a being defined with respect to the center of a sphere, a portion of which constitutes the shape of the cavity wall.

The cavity wall may include a largest dome-shaped portion, and the largest closed contour may be a contour edge of the largest dome-shaped portion.

The height (h) may be in the range of 0.02 to 0.35 times the maximum width (d) of the profile (0.02 ≦ h/d ≦ 0.35).

The height (h) may be in the range of 0.02 to 0.35 times the maximum width (d) of the profile (0.02 ≦ h/d ≦ 0.35). When the part of the inspection chamber (or the inspection chamber with said part) is in the range 1100 to 1300cm (preferably about 1250cm), the d/h value is preferably in the range between 3 and 12 (3. ltoreq. d/h. ltoreq.12). When the part of the inspection chamber (or the inspection chamber with said part) is in the range 900 to 1100cm (preferably about 1000cm), the d/h value is preferably in the range between 4 and 15 (4. ltoreq. d/h. ltoreq.15). When the part of the inspection chamber (or the inspection chamber with said part) is in the range 800 to 900cm (preferably about 850cm), the d/h value is preferably in the range between 12 and 41 (12. ltoreq. d/h. ltoreq.41).

The present disclosure relates to an inspection chamber component comprising any one or any combination (compatible to date) of the previously discussed features, which component is mountable to another component of an inspection chamber. The present disclosure also relates to an inspection chamber component comprising any one or any combination (compatible to date) of the previously discussed features, mounted to another component of an inspection chamber. In this context, "mounted" may be understood, for example, as reversibly or fixedly mounted to or integrally connected with another component.

The exam chamber components may be made at least in part by roto-molding. In fact, the entire exam room component may be produced by rotational molding. However, the present disclosure also relates to the components of the inspection chamber made by other methods including injection molding (injection molding), for example.

The reinforcing member may comprise polypropylene and/or polyethylene.

The present disclosure still further relates to an inspection chamber comprising inspection chamber components according to any of the previously discussed embodiments. The examination chamber may be formed integrally (as one piece) with the examination chamber components or the examination chamber may comprise additional separate components. The examination room may be at least partly made by rotational moulding. In fact, the entire inspection chamber can be produced by rotational moulding. However, the present disclosure also relates to inspection chambers made by other methods, including injection molding, for example.

Furthermore, the present disclosure relates to a method for manufacturing an inspection chamber component or an inspection chamber according to any of the previously discussed embodiments.

Additional advantages and features of the present disclosure, which may be realized alone or in combination with one or more of the features discussed above to the extent that the features are not inconsistent with each other, will become apparent from the following description of the preferred embodiments.

Detailed Description

Fig. 1A and 1B are side views (partial cross-sections) of an embodiment of an inspection chamber component 1 for placement underground containing groundwater.

The member 1 comprises a chamber 2 for receiving groundwater. Furthermore, the component 1 comprises a plate, one side of which constitutes a chamber wall 10, which chamber wall 10 partly defines the chamber 1. The chamber wall 10 is configured to retain groundwater in the chamber 2.

Furthermore, the component 1 of fig. 1A comprises a reinforcement member 3, which reinforcement member 3 is used to provide additional rigidity for maintaining the shape of the cavity 2. In particular, the cavity wall 10 comprises a central dome-shaped portion 11, and the additional rigidity is particularly conducive to maintaining the shape of the circular profile of the central dome-shaped portion 11, the "real" part of the cavity. In the case of this embodiment, the reinforcing member 3 is part of the cavity wall 10. In other words, the cavity wall 10 comprises a central dome-shaped portion 11 and a surrounding concave portion forming the reinforcement member 3. However, the present disclosure also relates to embodiments in which the reinforcing member comprises or consists of a component that is not part of the cavity wall.

Figure 1B is a side view (partially in section) of another embodiment of the inspection chamber component 1. The components of the member 1 are to a large extent identical to those of the embodiment of figure 1A and are therefore denoted by the same reference numerals. However, this embodiment comprises an additional reinforcement member 4 in the form of a plate, which is welded to the rest of the examination chamber part 1. In this case, the reinforcing member 3 (the surrounding concave portion 3) forming a part of the cavity wall 10 and the reinforcing plate 4 are each provided as a "reinforcing member".

In the case of fig. 1A and 1B, the inspection chamber component 1 also comprises a side wall 5. All of the surrounding concave portions 3 are located between the side walls 5 and the central dome-shaped portion. Further, the surrounding concave portion 3 (i.e., the reinforcing member 3) connects the side wall 5 and the central dome-shaped portion 11.

The embodiment of fig. 1A and 1B includes a surrounding concave portion 3 having a maximum width (a) greater than the thickness (t) of the cavity wall 10.

The cavity wall 10 of the embodiment of fig. 1A and 1B is concave/hollow when viewed from below (i.e., when viewed from the cavity 2).

Fig. 2A and 2B are partial perspective views of the embodiment of fig. 1A and 1B. As is apparent from fig. 1B, fluid, such as groundwater, can flow into and out of the chamber 2 through the fluid ports/openings 40. In other words, the port 40 constitutes an opening configured to pass the fluid through the reinforcing plate 4. Thus, fluid can flow into and out of the cavity through the "surrounding cavity" associated with the surrounding concave portion 3 of the cavity wall 10.

Figure 5 illustrates a number of geometric values that describe an embodiment of an inspection chamber component. In particular, the thickness t of the cavity wall 10 (in the case of this embodiment the thickness of the plate) is less than or equal to the maximum width a of the surrounding concave portion/reinforcing member 3. Furthermore, the chamber wall 10 comprises a central dome-shaped portion 11. The central dome-shaped portion 11 has the shape of a portion of a sphere. The radius R of the dome-shaped part is the radius of the circle surrounded by the contour of the central dome-shaped part 10 of the sphere, R ═ 2 ρ sin α, where ρ is the radius of the sphere and α is the maximum angle of half the area swept out by the part of the sphere covered by the central dome-shaped part 11. R is greater than or equal to the maximum width a of the surrounding concave portion.

Furthermore, a portion of the central dome-shaped portion 11 sweeps over the area of the sphere at a maximum angle 2 α ≦ 180. Furthermore, the height h of the central dome-shaped portion 11 is equal to or greater than the thickness t of the cavity wall 10 and equal to or less than the radius ρ of the sphere that describes the shape of the cavity wall central dome-shaped portion 10. The embodiment of fig. 1A and 2A is integrally formed as one piece and is manufactured by rotational molding. However, the present disclosure also relates to embodiments of different manufacturing, including, for example, the use of injection molding.

In addition to the reinforcing member 4, the embodiment of fig. 1B and 2B is also manufactured integrally, i.e. as one piece, by rotational moulding.

Fig. 3A depicts a cross-sectional view of the examination room 6. The examination room 6 comprises examination room parts 1. Fig. 3B is a top view of the examination room 6, and fig. 3C is a sectional view taken along line B-B in fig. 3B. The examination chamber part 1 at the lower end of the examination chamber 6 can be seen in fig. 3C. The examination chamber part 1 can be formed, for example, as one of fig. 1A and 2A or as one of fig. 1B and 2B.

In the case of the embodiment of fig. 3A to 3C, the examination chamber part 1 is an integral part of the examination chamber 6, at least in the case where the side wall 5 of the part 1 and the rest of the examination chamber 6 are made in one piece (formed by rotational moulding). However, the present disclosure also relates to an examination chamber component 1 that is separately made and is removable, or fixedly mountable, or mounted to another component of an examination chamber.

Figures 4A and 4B show cross-sectional views of an embodiment of the inspection chamber component 1, seen from below and (at least partially) from above, respectively. This embodiment comprises a reinforcing member in the form of a reinforcing plate 4 welded to the base part of the inspection chamber part 1. The reinforcement member 4 is provided with openings 40 for allowing fluid to enter the outside of the cavity 2. In the case of this embodiment, the cavity wall is made of a single dome that is hollow/concave (when viewed from below, i.e. from the side of the cavity 2) and has the shape of a portion of a sphere (see fig. 4B).

Many additional variations and modifications are possible and should be understood to fall within the framework of the present disclosure.
