Definitions
- the invention relates to a method for free milling a manhole cover and / or a manhole cover support with a round milling head and a device for carrying out of the procedure.
- manhole covers and manhole cover supports or drilled such that a cylindrical Milling or drilling head the manhole cover and the Manhole cover support milled or drilled. It will be vertical Milled edges generated, and the manhole cover support with the manhole cover is lifted out.
- Manhole covers are nowadays for larger loads, designed for example up to 40 tons.
- the entire substructure the shaft is designed for these high loads, in particular for older shafts, not designed. It means that either the entire manhole base can also be replaced must, which is very expensive, or the substructure is not removed, often causing settlement damage occur.
- the technical problem underlying the invention is a method for milling a manhole cover and / or to specify a manhole cover support at which the disadvantages mentioned do not occur, as well as a Device for performing the method and a Manhole.
- the manhole cover and / or the manhole cover support with a round milling head, which creates an oblique milling edge, is milled free is with a renovation or with a New construction of the shaft, a hole with an oblique milling edge available, in which a new manhole cover support is inserted becomes.
- This new manhole cover support is based on the oblique milling edges in the carrier layer of the Road asphalt, so that not the entire load of the Manhole cover support and manhole cover from the substructure is worn, but much of the pressure from that Asphalt or the ground is picked up.
- the method according to the invention is a remediation of a manhole so possible that the manhole cover and / or the manhole cover support with angled milling edge be milled free.
- the manhole cover and the manhole cover support are then removed. After that a new manhole cover in the milled opening with the oblique milling edges, and the manhole cover is finally inserted into the manhole cover support.
- the shaft When the shaft is rebuilt, the shaft is moved into the Road construction introduced. A dummy cover is placed on the shaft assembled, and then the road is paved. Then the blind cover with the invention Device according to the inventive method milled free in such a way that the inclined milling edges arise. Then the manhole cover support inserted with the manhole cover.
- the application of the method according to the invention in a New shaft construction has the advantage that significantly less Settlement damage occurs as per the state of the Technology-related shafts.
- a manhole cover support is advantageously used, which also has tapered side surfaces. This ensures an optimal distribution of power to the surrounding asphalt reached.
- the is particularly advantageous Inclination angle of the tapered side surfaces essentially equal to the angle of inclination of the oblique Milled edges formed. This creates an optimal power distribution on the asphalt base course and Manhole base reached.
- a mortar is placed in the opening with the sloping edges. It is preferably a high-strength, fast-curing assembly or grouting mortar.
- This mortar serves two purposes. On the one hand, this creates a non-positive connection between the manhole cover support and the oblique edges of the milled opening. As a result, the manhole cover support is optimally supported on the asphalt support layer. On the other hand, the mortar makes it possible to level the manhole cover when inserting it, so that a flat surface is created at the end and the manhole cover is level with the road surface.
- the oblique milling edge with a Milling head formed which is also a conical has a tapered shape.
- the side faces of the milling head, that are tapered are studded with milling chisels.
- the lower annular rim of the Milling head has additional milling chisels.
- the milling head according to the invention is on conventional milling devices arranged.
- This device has a support frame.
- the Support frame in turn has three support legs to one to achieve a firm stand during the milling process.
- the Device is on a carrier vehicle, as on one Excavator, backhoe loader or crane arranged.
- the engine of the Device is powered by a hydraulic system of the carrier vehicle driven.
- the device has an outer and an inner Lead frame, with the milling head according to the invention the inner guide frame is arranged. This inner one The lead frame is vertical against the outer lead frame displaceable.
- edge area is large when renovating a shaft damaged, with an additional cone ring the loads on the intact area further out be transmitted.
- the cone ring has an adapter function on.
- Fig. 1 shows a device (1), which is conical has tapering milling head (2).
- the milling head (2) has milling bits (4) on its side surface (3).
- a lower annular rim (5) also carries Milling chisel (6).
- the device is an attachment to a carrier vehicle (not shown) trained.
- the device For this purpose (1) has a suspension (7).
- the device (1) is supported by three support legs (8, 9, 10).
- the carrier vehicle (not shown) forms a counter bearing in such a way that a pressure in the direction of the Arrow (A) is exercised during the actual milling process.
- the device (1) is above a shaft (11) arranged.
- the shaft (11) is to be renovated, such that a cylindrically shaped manhole cover support (12) with a manhole cover (13) is removed.
- the shaft (11) has a shaft cone (14).
- the manhole cover support (12) is in an asphalt support layer (15) and an asphalt surface course (16).
- the opening (17) has oblique milling edges (18, 19).
- a mortar (20) is advantageous in the opening (17) a high-strength, fast-hardening grout in turn a manhole cover support (21), such as shown in Fig. 3 is used.
- the manhole cover support also has tapered side surfaces (22), whose angle of inclination is the angle of inclination the oblique milling edges (18, 19) are adapted.
- the Manhole cover support (21) is inserted into the mortar (20). On the one hand, this creates the non-positive Connection between the manhole cover support (21) and the Asphalt carrier layer (15). On the other hand, this is a Height compensation possible, so that a flat road surface (23) is formed.
- the manhole cover support (21) is also on a Substructure (24) from the grout (20). With the Substructure (24) is the actual height compensation.
- the manhole cover support (21) has a circumferential one Edge (27) on for asphalting in the ceiling exclusion.
- the manhole cover is placed in the manhole cover support (25) used. Before or after inserting the manhole cover (25) finally becomes a fine layer (26) of asphalt applied to the asphalt support layer (15).
- the manhole cover support (21) is at an angle has extending side surfaces (22) over the mortar (20) a positive connection with the bevelled edges (18, 19) of the opening (17), the force that on the manhole cover support (21) and manhole cover (25) acts, transferred to the asphalt support layer (15), so that the manhole base (11) with the manhole cone (14) is relieved.
- the force is divided into one horizontal and a vertical component. simultaneously there is a reduction in horizontal thrust.
- the method according to the invention is for new road construction to avoid damage caused by subsidence.
- the method according to the invention can Rehabilitation of manholes and manhole covers at low cost be applied.
- the repeated, with very high costs associated adjustment or lifting of the manhole cover is not necessary.
- Fig. 4 shows a shaft (28). Above the shaft (28) is an opening (29) with an oblique design Side surfaces (30) formed. In the opening (29) is a additional cone ring (31) arranged, which has an adapter function for the manhole cover support (32). By the conical formation of the cone ring (31) and Manhole cover supports are in the direction of the arrow (B) forces acting in turn in horizontal and vertical Components divided. Below the cone ring (31) and the manhole cover support (32) is made of a substructure (33) Grouting mortar for leveling the manhole cover support (32) and the conical ring (31) are provided.
- the asphalt base course (34), the cone ring (31) and the manhole cover support (32) are (partially) with a Cover layer (35) covered with asphalt.
- the manhole cover (36) is arranged in the manhole cover support (32) in the manhole cover support (32) in the manhole cover (36).
- FIG. 5 shows the state after the milling process has ended with the milling device according to the explanations Fig. 1 and Fig. 2, partially cut. Same parts are provided with the same reference numbers.
