Abstract

The utility model relates to a rotational moulding inspection well. The inspection well comprises a cylindric shell molded once by rotational moulding. The shell is equal in wall thickness. The upper opening part of the shell is provided with a fixed safety net and an open type inner cover of the well. Convex straight ribs and convex horizontal ribs perpendicular to the straight ribs are uniformly distributed on the outer peripheral surface of the shell along the axial direction. Trapezoidal concave grooves arranged into a matrix are arranged between adjacent straight ribs and horizontal ribs. The shell can be made into an L shape, or a Y shape, or a reverse T shape, or a + shape. The inspection well realizes standard production and civilized construction. The utility model has the advantages of high construction efficiency, good leakproof properties, long service life and high safety.

Description

The rotational moulding manhole

Technical field

The utility model relates to the attached part of constructing in a kind of rainwater, the sewage vent line, particularly a kind of rotational moulding manhole.

Background technology

Manhole is a kind of attached part of constructing that is used for rainwater, sewage vent line, is to be convenient to make regular check on dredging pipeline, to prevent the necessary facility of line clogging.The tradition manhole is on-the-spot brick product with brick, is provided with unified standard, and efficiency of construction is very low, is connected weak effect with pipeline, and leakiness is especially done to work as well lid breakage or stolen when inspection shaft uses, and easily causes people, car safety problem.

Summary of the invention

Goal of the invention of the present utility model is to overcome the defective of prior art and a kind of prefabricate standard product, rotational moulding manhole is provided, to improve efficiency of construction, barrier performance and application life.

According to the foregoing invention purpose, embodiment of the present utility model is: a kind of rotational moulding manhole, and it comprises tubular shell and open-type well inner cap, it is characterized in that rotation molding of described housing, its upper oral part is provided with fixing safety net.

Described tubular shell is the cylinder thin wall shape, and wall thickness equates, is provided with the convex horizontal bar of straight muscle of uniform convex and straight vertical muscle vertically at the housing outer circumference surface, is the groove of the matrix trapezoidal indent of arranging between adjacent straight muscle and the horizontal bar.

Described housing is " L " type or " Y " type or " ⊥ " type or " ten " font.

Compared with prior art, the utility model adopts rotational molding technique one-shot forming manhole, realizes standardized production and civilized construction, and it is also advantageous in that: 1. efficiency of construction height, and installation rate is fast, and only need 0.5～1 hour are installed; 2. barrier performance is good, owing to good connecting effect, has solved the leakage problems of brick well and joint for plastic tube, reduces the underground water infiltration capacity, reduces sewage and oozes out the pollution that underground water is caused; 3. long service life has solved brick well sand finish easily by the acid and alkali corrosion problem, and the borehole wall is convenient to remove dirt, is convenient to maintenance; 4. safety is good, just in case well lid is damaged or stolen, can not cause any accident.

Description of drawings

Fig. 1 is the utility model sectional structure schematic diagram.

The specific embodiment

In conjunction with the accompanying drawings the utility model embodiment is specifically described again below.

As shown in Figure 1, the rotational moulding manhole is to utilize the one-time formed manhole of rotational molding technique, housing 1 upper oral part of this manhole is provided with the well inner cap 3 of fixing safety net 2 and open-type, covering the back in the well remains basically stable with the road surface, housing 1 wall thickness of cylinder thin wall shape equates, being provided with the convex horizontal bar 4 of straight muscle 5 of uniform convex and straight vertical muscle vertically at outer circumference surface, is the groove 6 of the matrix trapezoidal indent of arranging between adjacent straight muscle and horizontal bar, to strengthen intensity.Housing 1 is made " L " type or " Y " type or " ⊥ " type or " ten " font, adapts to different occasion needs.

The how logical pattern that this manhole also can be made into multi-angle, different level, different tube diameters as required can realize civilized construction, can reduce the influence that when construction brings road traffic and surrounding environment to greatest extent.
