The invention relates to maintenance of roads, in particular to the restoration of the deformed manholes manholes of underground utilities.

The problem is that work on the restoration of the deformed manholes inspection chambers, typically performed manually mark covers the observation wells are aligned with marks on the road surface.

Known way to restore the deformed asphalt pavement around the wells, including the destruction of the top layer of the coating material, the introduction of a new material, its levelling and compaction [1]

However, when repairing manholes wells this method is technologically complicated and requires more labor. In addition, often is the collapse of part of the material into the well.

There is also known a method and apparatus used in the construction of the lined trench, when use spatial design, having one or more frame elements, supports removable formwork for walls in which the trench recess is placed a movable stiffening mixture [2]

However, this solution is difficult in design execution and does not provide the necessary facilities because conditions remain uncomfortable, are often on the knees, manually, with the inevitable clogging of wells waste.

Closest to the invention to the technical essence and the achieved result is a recovery method covers the observation wells in the road surface by repairing the neckline and support ring, and macgeorge rings [3]

However, the known solution, providing the exception of the necessary dismantling of the structures and the surrounding coating requires a special construction of the sight ring that limits the scope of the possible use of known solutions.

The objective of the invention is to develop a technologically simple and convenient way to repair manholes inspection chambers and devices for its implementation.

The problem is solved due to the fact that in the method of restoring the hatches observation wells in the road surface by repairing the neckline and back-up ring repair neck support ring is carried out by lowering the mouth of the well with the lower part of the working platform formwork, form and dimensions of which correspond to the size and shape of the inner walls of the mouth of the well, the bearing casing on a healthy road surface and vertical movement of the casing to the location of the upper level it at the required level restored support ring, followed by packing for casing movable stiffening of the mixture. In the device for repair manholes inspection chambers, comprising a device for repair of neck and base coltime guides on the inner surface, hosting rods G-shaped, the upper bent ends of which form abutment shoulders. This shell may be made of flexible durable material, for example sheet steel. On the supporting shoulders of the l-shaped rods can be fixed arm. Shell in the lower part may be provided with a device for transporting, for example, a wheel.

In Fig. 1 shows a diagram of the location of the casing cap of the well when the recovery operation of the hatch of the well; Fig. 2 is a view in plan; Fig. 3 the device (side view according to Fig. 1), General view.

The casing made of a flexible durable material, such as stainless steel sheet. It is given by the shape and dimensions of the inner walls of the mouth of the well. As a rule, the standard wells perform a round shape with a diameter of the neck of 700-800 mm In the example shown formwork, made in the form of a circular shell 1 with the false bottom 2. To the inner side of the shell is welded to the vertical tube 3, which serve as guides for the rods 4, freely moving inside the tubes. The rods 4 are D-shaped, i.e., their upper ends at the exit of the tubes 3 are bent at right angles, forming a supporting shoulder 5 for adewusi vertical movement of the shell 1 at the mouth of the well. Hanging plate 2 consists of a round pad welded to a strip of iron, the ends of which, in turn, welded to the inner wall of the shell 1. On the upper bent ends of the l-shaped rods 4 fixed arm 7 for ease of installation and removal of formwork. On bottom of the bottom 2 fixed wheel 8 for convenience of moving fixtures on the front of the work.

Method of recovering hatches and asphalt pavement around the wells with the use of this device is as follows. Using the arms 7, the lower shell in the mouth of the well so that the abutment shoulders 5 of l-shaped terminals 4 formed on a healthy road surface. With nuts 6 shell 1 is moved vertically so that its top mark was at the required level restored support ring hatch well. The work falls into the shell 1 and is suspended the bottom 2. Here he performs all work on the restoration of the support ring under the hatch well by stacking bystrootverdevayuschey cement concrete 9 or concrete segments /not shown/ mortar or mastic asphalt, using the shell as the formwork. After completion of the cowling removed from golovintsy simple, to perform sophisticated, enhances productivity, improves the production culture. In addition, significantly increases the service life of hatches by providing them dense and uniform bearing on the base. Organization of repair work is more rational, eliminating the need for cleaning wells from production waste. Such a device allows for the proposed technology to carry out the installation of the hatch covers of the well to a predetermined level, which cannot be performed using known solutions.
