Description

2. Manhole according to claim 1, characterized in that it is particularly advantageous if the art indicates that the plastic pipes or fabric pipes or pipe sockets with parallel to the pipe -pipe socket with welded strips running parallel to the longitudinal axis of the pipe running, welded strips (8, 9 and 10) plastic are provided, the holes for receiving are made of plastic, the holes (11) for 25 semicircular bent wires for the reinforcement Receiving semicircular bent wires for having their ends guided through the holes have the reinforcement (12), which are bent over by the. The reinforcement is therefore light Holes (11) guided ends (24 or 25) to be attached.

genes are. It has also proven advantageous.

3. Manifold according to claim 2, characterized 30 if at least one with the semicircular, that at least one with the wires firmly connected, parallel to the pipe longitudinal axis semicircular wires firmly connected, par extending connecting strut is arranged; because all of the connections running to the pipe's longitudinal axis give the wires a firm hold,
extension strut (23) is arranged. In addition, between the on the plastic

4. Manifold after one of the cams welded on to the pipe or pipe socket Claims 1 to 3, characterized in that between or the collar and the inside shaft opening on the plastic pipe or tubing on the plastic pipe or pipe socket trim welded-on cams or the Ki a- with holes and grind through them or wiggle (17 or 18) and the inside box-shaped wire provided with a plastic ring Opening be welded onto the plastic pipe or pipe 40. This also increases the stability trimmed with bores and improved by these.

wire (22) guided in the shape of a window or wave.

plastic ring (20) is welded on. game of the invention described. It shows

F i g. 1 a distribution shaft in a vertical section with a plastic pipe cut in the longitudinal direction,

F i g. 2 the distribution shaft according to FIG. 1 with across

The invention relates to a prefabricated cut plastic pipe and
Divider manhole for sewer systems with one manhole F i g. 3 a three-dimensional representation of the plastic

Part made of concrete or the like, in which in the area of the 50 pipe with reinforcement.

The lower part of the manhole is open at the top, the divider chamber 1 consists of the manhole

conduit pipes or pipe sockets made of plastic, in particular 2, 3 and 4, the manhole base 5 and the special polyethylene, are embedded onto which in the manhole cover 6. A cam or collar open to and from the manhole walls in the region of the manhole Downstream pipe 7 made of plastic can be welded on .... 55 consist of one piece or two pipe sockets.

With a supply and discharge pipe from the magazine »Kunststoffe«, 1967, different nominal S. 92, known sewer shaft of this type are the wide and, seen in plan view, from verim Area of the walls of the manhole base in different directions on the distribution manhole Polyethylene pipe socket welded collar to be closed. The number of inlet and outlet die only measure to the pipe socket in the 60 pipes depends on the diameter of the lower part of the manhole to anchor tightly. Because of the rigid shaft and the intended use. On the ken temperature expansion of the polyethylene can supply and discharge pipe 7 are strips 8, 9 between the pipe socket and the surrounding him and 10 welded or glued on from plastic Concrete, however, joints are created by the water (Fig. 2) with holes 11 to accommodate a penetration can. 65 reinforcement 12 made of semicircular bent wires The invention is therefore based on the object to be provided. The bars can be sawtooth-like a completely dense, with inlet and outlet (Fig. 3) or smooth (Fig. 1). The supply pipes or pipe socket made of plastic piping and drainage pipe? is in the area of

Manhole ring 4 open at the top. All joints are opposite the manhole ring 4 and the manhole base 13, 14,15 i <nd 16 sealed with permanent elastic cement A conical collar 17 or 18 is firmly connected to the inlet and outlet pipe 7 in a known manner. Between the collar and the manhole ring 4 there is still an outwardly to Lonisch trained concrete ring 19. It is supported by a plastic ring 20, which is connected to the supply and discharge pipe? is firmly connected and has holes 21, ge ίο hold and reinforced. Through the holes 21 is spiral a wire 22 is drawn, which serves to better reinforce the concrete ring 15.

Fig.? shows the reinforcement, rings and strips on the supply line ^ - and discharge pipe 7. The semicircular bent wires are connected by means of connecting struts 23, which are firmly connected to the wires, fixed in place. When the plastic pipe is inserted into the lower part of the manhole, the entire Reinforcement in the still soft concrete and is firmly embedded after it has hardened, especially the ends 24 and 25 penetrate deeply into the concrete and are firmly anchored in the process. . ,,, __,

The manhole can be produced in two ways. In a cylindrical lower part of the manhole 26 (dashed in Fig. 2) is denoted by SSe Holes made in the pipe ^ with concrete 27 filled, leveled, compacted and ^ smoothed. the Reinforcement wires sit firmly in the concrete; joints 13, 14, 15 and 16 are filled with permanently elastic putty. The concrete ring 19 is then molded from the outside

The second type of production sees the embedding of the reinforced pipe in the lower part of the manhole 5 before; then the manhole ring 4 is put on and cast on.

Claims (1)

Henen prefabricated concrete manhole to patent claims: create. This object is achieved according to the invention 1. Prefabricated manhole for Kanalisa- solves that the supply and discharge pipes or functions with a manhole base made of concrete 5 pipe sockets by means of a fixed on them od The manhole top open supply and discharge pipes or lower part made of concrete are connected and that the joints of plastic pipe sockets, in particular poly- are embedded between the concrete parts on the one hand and the plastic, on the other hand with a shaft wall cams in the area of the fabric pipes or pipe sockets or collars are filled with permanently elastic joints,
are welded, characterized by the fixed reinforcement on the pipes or pipe sockets, the lower part of the manhole is arranged in the loading (7) or pipe socket by means of a fixed to them area of the pipe entry less prone to cracks Reinforcement (12) made of steel wire. Stresses due to temperature fluctuations or the like with the manhole base (5) made of concrete 15 are connected through the distributed over a larger area and that the joints (13,14,15 and anchoring of the pipes or Pipe sockets well balanced between the concrete parts on the one hand and the similar ones. The avoidance of stress cracks in the Be-Kunststcffrohren or -pipe sockets on the other hand, together with the permanently elastic Fumit a permanently elastic joint filler, helps to achieve a largely tight seal. 20 final.
