Abstract

This invention belongs to the field of railroad construction, more directly, to the post-crane track device of the tower cranes.Purpose: to cheapen the post-crane track device, to decrease the labour costs involved with the equipment, and to economize inert substances.It comes through equipping cross post-crane ferro-concrete panels with a trough gully. The panels are set with the side edges close to each other, composing a chamfer for a gritty substratum. The gritty substratum acts as the lining and the even load distribution to the longitudinal mudsills with railing.

Description

The invention relates to the field of railway construction, directly to the installation of a post-crane track for tower cranes.

BACKGROUND OF THE INVENTION Installation of an upper road structure on reinforced concrete track bases (USSR a.l. 1461810) having longitudinal gullets connected by transverse beams. A disadvantage of the present invention is that the gravel or crushed material used for the foundation installation can only be partially reused, and the greater part of these materials is spread on the site and pressed into the soil and is no longer used.

The object of the invention is to reduce the cost of installing a post-crane road, and to reduce labor costs for its installation.

The objective is achieved by installing transverse post-mortem reinforced concrete slabs with a trough. The panels are placed side by side along the edges, forming a trough for sandblasting. The sand bed serves for leveling and evenly distributing the load on the longitudinal sleepers with rails.

The essence of the invention is that the transverse plates are made with slabs for the installation of a sand layer under the longitudinal beds.

An advantage of the present invention is that no gravel or rubble serving as a ballast for post-crane roads is required when installing aftermarket roads. After construction, the foundation of the post-crane road is easily disassembled from reinforced concrete slabs with sand layer and used for installation of other post-crane roads. In this way, it is possible to reuse the foundation of the postcranial road and save gravel and crushed stone.

The main difference is that the transverse plate has a trough for the installation of a sand pillow, which evenly distributes the loads and smooths the longitudinal beds. The post-mortem path installed on the post-mortem slab with sand layer is completely prefabricated and dismantled.

The drawing shows a cross-section of a sub-crane plate: a transverse plate 1 having a trough 2, into which a layer of sand is placed, with longitudinal rails 5 attached to the layer.

(cushion) 3. The sandbeds 4, with the pre-crane road, shall be arranged as follows: The site shall be leveled, reinforced concrete slabs 1 shall be placed with troughs 2, which shall be filled with a sand layer (pillow) 3. Longitudinal sleepers 4 with rails 5. Upon completion of the construction work, the sub-crane road and base shall be dismantled retrospectively and used in other facilities.

Re-use of sand-based reinforced concrete post-slab panels instead of single-gravel-rubble foundations allows saving inert materials and reducing work costs.

Claims (2)

DEFINITION OF INVENTION 1. An undercut path having rails fixed on longitudinal sleepers mounted on a base, 5, characterized in that the base is made of reinforced concrete slabs with slabs, which form a continuous trough for longitudinal installation of the sleepers. 2. The post-mortem route according to claim 1, characterized in that the equalization of the longitudinal beds and the even distribution of loads between the longitudinal and reinforced concrete slabs is a sand or gravel layer.
