Abstract
The utility model provides an inspection well and belongs to the technical field of rotational molding. The inspection well solves the problem that the strength of the present inspection well is insufficient. The inspection well comprises a well base with an opening at upper end and at least two connecting holes at lower end; a connecting pipe is connected with the connecting holes; the opening is communicated with the connecting holes; a plurality of reinforcing ribs are arranged on the well base; and the cross sections of the reinforcing ribs are ladder-shaped. The inspection well has the advantages of high strength and long service life.
Description
Technical field
The utility model belongs to the rotational moulding technical field, relates to a kind of manhole.
Background technology
Manhole generally is located on drainage pipe intersection, turning, caliber or gradient change place, drop place and the straight line pipeline section and locates at a certain distance, be convenient to make regular check on, the draining ancillary structure of cleaning and dredging pipeline.
Disclosed a kind of manhole is arranged at present; Comprise that the upper end has parent and two tube connectors that opening and two ends have connector respectively, opening and two connectors are interconnected, and the inner mouth of pipe of two tube connectors can be connected with two connector removable seals respectively; Its open lower end place of parent is provided with the reinforcing rib of a plurality of horizontally sets; Be provided with a plurality of vertically disposed reinforcing ribs between two tube connectors of parent bottom, reinforcing rib is elongated strip, and the problem of its existence is: because reinforcing rib is elongated strip; Its intensity is not very enough, thereby is not clearly to the whole stiffening effect of parent.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, thereby has proposed a kind of manhole that the high strength reinforcing rib can improve bulk strength greatly that which is provided with.
The purpose of the utility model can realize through following technical proposal: manhole; Comprise that the upper end has the well seat that opening, lower end have at least two connectors; Be connected with tube connector on the connector; Described opening and above-mentioned connector are communicated with mutually, it is characterized in that: described well seat is provided with several reinforcing ribs, and the cross section of described reinforcing rib is trapezoidal.
In above-mentioned manhole, the number of described connector is two or three.
The manhole of two connectors is straight-through manhole, and the manhole of three connectors is the threeway manhole.
In above-mentioned manhole, described connector and tube connector are for being threaded.
In above-mentioned manhole, described reinforcing rib is that the well seat wall convexity that stretches out forms, and the trapezium structure of its cross section is outer narrow inner width.
In above-mentioned manhole, described reinforcing rib comprises horizontal reinforcing rib and waling, and its horizontal reinforcing rib is arranged on its place, opening below of well seat, and waling is arranged on well seat bottom.
Compared with prior art, this manhole has following several advantage:
1, to make cross section be trapezoidal structure to the reinforcing rib on this manhole well seat, makes the intensity of reinforcing rib self increase, thereby improved well seat integral intensity, makes it be difficult at work being damaged, and improves the application life of manhole;
2, tube connector and connector are dismountable annexation; One end size of its tube connector is coincide with the supporting of connector; The size of the other end differs, and the tube connector that the well seat only need be changed different size just can connect with the pipeline of different size dimensions, and is applied widely;
3, this reinforcing rib structure both can be applied on the straight-through manhole, also can be applied on the manhole of threeway.
Description of drawings
Fig. 1 is the structural representation that its two connector is the straight line angle in the utility model.
Fig. 2 is the structural representation that its two connector is 135 ° of angles in the utility model.
Fig. 3 is the structural representation of the utility model when being threeway.
Among the figure, 1, the well seat; 2, tube connector; 3, reinforcing rib.
The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1, this manhole comprises that the upper end has the well seat 1 that opening, lower end have two connectors, and tube connector 2 has been threaded on the connector; Opening and connector are communicated with mutually; Place, its opening below is provided with a plurality of horizontal reinforcing ribs 3 on the well seat 1, and its bottom is provided with a plurality of walings 3, and all horizontal reinforcing ribs 3 and waling 3 form for the well seat 1 wall convexity that stretches out; Its cross section is trapezoidal, outer narrow inner width.
Two connectors in the present embodiment are that straight line is communicated with, and its two connector also can be 135 ° of angles and be provided with, and is as shown in Figure 2.
Connector in the present embodiment is 2, and its connector also can be three, and is for the threeway manhole, as shown in Figure 3.
It is trapezoidal structure that reinforcing rib 3 is made cross section, makes the intensity of reinforcing rib 3 self increase, thereby has improved well seat 1 integral intensity, makes it be difficult at work being damaged, and improves the application life of manhole; The screw connection structure of connector and tube connector 2 makes 1 tube connector 2 that needs to change different size of well seat just can be connected with the pipeline of different size dimensions, and is applied widely.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
