Description

Изобретение относится к мостостроению и может быть использовано при возведении путепроводов в насыпях железнодорожного полотна из трех путей и более.The invention relates to bridge construction and can be used in the construction of viaducts in embankments of a railway bed of three tracks or more.

Известен путепровод в насыпи существ- ⁵вующего железнодорожного полотна, выполненный в виде монолитной Железобетонной замкнутой рамы, и способ его сооружения, включающий устройство в пере— рывах движения поездов фундаментов и пролетного строения временного моста, разработку под его прикрытием котлована с откосами, разработку в нижней части котлована по оси путепровода траншеи ₁₅с установкой забивных креплений, бетонирование в траншее плиты, служащую основанием для устройства пути надвижки, бетонирование в проектном уровне на плите рамы путепровода со съемными ноже- го выми стенками, устройство на другом конце плиты консоли, упоры для тяговых домкратов, установку домкратов с тягами, перемещение рамы по двум металлическим путям скольжения, расположенным на бетонном основании; продавливание рамы' путепровода в оставшуюся часть насыпи с удалением грунта, разборку временного моста [ 1 ] .Known overpass in the embankment of the existing ⁵ railroad tracks, made in the form of a monolithic reinforced concrete closed frame, and the method of its construction, including the device during interruptions in the movement of foundations trains and the span structure of the temporary bridge, development of a foundation pit with slopes under its cover, development in the lower part of the guideway axis excavation of the trench ₁₅ with the installation of driven fasteners, concrete slab in the trench, serving as a base for the device sliding path, concreting in the project at the plate level p we guideway removable nozhe- Vym of walls, the device at the other end of the cantilever plate stops for traction jacks, jacks with installation rods, frames for moving the two sliding metallic paths arranged on a concrete base; punching the frame 'overpass into the remaining part of the embankment with soil removal, disassembling the temporary bridge [1].

Недостаток этого путепровода и способа его сооружения заключается в возможности перекрытия им относительно небольшого отверстия, а также в значив· тельной трудоемкости его монтажа, обусловленной необходимостью бетонирования рамы путепровода на месте, устройством временного моста с послед у юшей его разработкой, укладкой основания и пути скольжения рамы путепровода.The disadvantage of this overpass and the method of its construction is the possibility of blocking it with a relatively small hole, as well as the considerable complexity of its installation, due to the need to concrete the frame of the overpass in place, the construction of a temporary bridge with its subsequent development, laying the base and sliding path of the frame overpasses.

Наиболее близким к предлагаемому является путепровод в насыпи существующего железнодорожного полотна, включающий столбчатые опоры, насадки и установленные на них балки пролетного строения с верхним строением пути, причем верхнее строение пути содержит поперечно члененную на блоки плиту проезда, уложенную на балки пролетного строения, ,981495 4 и предназначено для однопутного дви— действующего верхнего строения пути в жения [21.Closest to the proposed one is an overpass in the embankment of the existing railway bed, including columnar supports, nozzles and beams installed on them with a superstructure with the upper track structure, the upper track structure containing a passage plate transverse to the blocks laid on the superstructure beams, 981495 4 and it is intended for a single-track moving superstructure of the pathway [21.

Известен также способ сооружения описанного путепровода в насыпи существующего железнодорожного полотна, вклю- ₅чающий удаление верхнего строения пути в зоне расположения путепровода, возведение в грунте насыпи столбчатых опор с насадками, установку на них балок пролетных строений с верхним строением ю пути и выемку грунта насыпи под путепровод, причем после устройства насадок на них устанавливают временный мост, под его защитой производят частичную выемку грунта, в перерывах движения производят разработку временного моста, устанавливают на балки пролетного строения блоки плиты с верхним строением пути, после чего производят окончательную выемку грунта насыпи и укрепление 20 головной части насыпи сборными железобетонными стенками [2) .There is also known a method of constructing the described overpass in the embankment of an existing railway track, including ₅ removing the upper track structure in the zone of the overpass location, erecting columnar supports with nozzles in the soil, installing beams of spans with the upper track structure and excavating the embankment underneath overpass, and after installing the nozzles, a temporary bridge is installed on them, under its protection a partial excavation is carried out, during breaks of traffic, a temporary bridge is developed, vayut beam on the span plate blocks the upper path structure, whereupon final excavation and embankment head portion 20 strengthening embankments precast concrete walls [2).

Недостаток известного путепровода и способа его сооружения заключается в повышенной трудоемкости его монтажа, обу— 25 словленной необходимостью установки большого количества блоков плиты верхнего строения пути на балки пролетного строения, а также в существенном снижении эффективности эксплуатации железной эд дороги при сооружении путепровода вследствие необходимости устройства временного моста и блоков плиты верхнего строения пути за счет организации перерывов в движении поездов. _w A disadvantage of the known overpass and the method of its construction is the increased complexity of its installation, due to the need to install a large number of blocks of the plate of the upper track structure on the beams of the superstructure, as well as to a significant decrease in the efficiency of operation of the railway ed during the construction of the overpass due to the need for a temporary bridge and blocks of the plate of the top structure of the track due to the organization of breaks in the movement of trains. _w
