Description
В известных сборных жсотезобетонных обделках св зи между отдельными элементами в кольце и . между отдельными кольцами обделки осуществл ютс посредством болтовых соединений или закладных деталей, что усложн ет и удорожает производство работ.In the well-known precast concrete lining of communication between the individual elements in the ring and. between the individual rings, the lining is carried out by means of bolted joints or fixings, which complicates and increases the cost of work.
Существует также сборна обделка тониел из железобетонных фасонных блоков с непараллельными клиновидно срезанными внутррз обделки торцовыми гран ми.There is also a composite lining of reinforced concrete shaped blocks with non-parallel wedge-shaped cut inside the lining of the lining with face edges.
Предлагаема ио изобретению сборна обделка характеризуетс использованием последней.The inventive composite lining is characterized by the use of the latter.
У;;W ;;
Отличительна Усооенность ее состоит в том, что, с целью прочного соединени колец обделки и исключени перемещени одного из них относительно другого, продольные грани блоков, параллельные поперечному сечению тоннел , снабжены углублени ми и выступами. Така форма блока обеспечивает взаимную св зь блокор в кольце и смежных колец между собой в собранной обделке без применени болтовых соединений или закладных деталей.Its distinctive feature is that, in order to firmly join the lining rings and eliminate the movement of one of them relative to the other, the longitudinal faces of the blocks parallel to the cross section of the tunnel are provided with recesses and projections. Such a block form allows the blocker in the ring and the adjacent rings to communicate with each other in the assembled lining without the use of bolted joints or fixings.
Блок имеет два отверсти дл нагнетани раствора за обделку и два рыма дл захвата блока при его укладке и транспортировке.The block has two apertures for injecting mortar for the lining and two eyes for gripping the block during its laying and transportation.
На фиг. 1 показан общий вид обделки тоннел ; на фиг. 2 - поперечное сечение обделки.FIG. 1 shows a general view of the lining of the tunnel; in fig. 2 is a cross section of the lining.
Здесь рымы дл захвата блока обозначены цифрой 1, а отверсти дл нагнетани раствора за обделку - цифрой 2.Here, the grippers for blocking are indicated by the numeral 1, and the injection holes for the solution for the lining are designated by the numeral 2.
На фиг. 3 представлен вид обделки с внутренней стороны (лева часть чертежа) и вид обделки с внешней стороны (права часть чертежа).FIG. 3 shows the view of the lining from the inside (left part of the drawing) and the view of the lining from the outside (right part of the drawing).
Предмет изобретени Subject invention
Сборна обделка тоннел из железобетонных фасонных блоков с непараллельными клиновидно срезанными внутрь обделки торцовыми гран ми, отличающа с тем, что, с целью прочного соединени колец блочной обделки и исключени перемещени их относительно друг друга, продольные грани блоков, параллельные поперечному сечению тоннел , снабжены ™,f « S которые заход т соответственно выступы и углублени блоков смежных колец.A composite tunnel lining of reinforced concrete shaped blocks with non-parallel wedge-shaped end faces cut off the lining, characterized in that, in order to firmly join the block lining rings and prevent them from moving relative to each other, the longitudinal faces of the blocks parallel to the tunnel cross-section are provided with f S which fit respectively protrusions and depressions of blocks of adjacent rings.
