Description
Technical field
The utility model relates to metro built by mining method retaining head unit, is specially a kind of metro built by mining method secondary lining pin-connected panel retaining head unit.
Background technology
Subway tunneling running tunnel is selected shield method more and more.But, because shield method is not suitable in uneven strata, constructing; Can not be applicable to the line of turning back, the complicated section construction of branch-cut bridge equal section; Distance between centers of tracks location less than normal, the construction of pile foundation underpinning section.And Mine Method in, uneven, the shallow buried covered excavation section of little weathered layer, distribution of strata and be inappropriate for worker's method that the shield construction location is still frequent selection.Two lining construction natures become an important step in the Mine Method construction.
When yet existing secondary lining retaining head unit is constructed, exist easy disconnection of constuction joint place reinforcing bar and waterproofing materials that defectives such as not in place are installed, can not guarantee that vertical differential settlement of underground structure is controlled at the requirement that allows deformation range, hoop water-tight.
Summary of the invention
The utility model because unreasonable structure causes constuction joint place reinforcing bar to be prone to break off and waterproofing materials is installed problem not in place, provides a kind of metro built by mining method secondary lining pin-connected panel retaining head unit in order to solve existing secondary lining retaining head unit.
The utility model is to adopt following technical scheme to realize: metro built by mining method secondary lining pin-connected panel retaining head unit; Comprise an arcuation retaining steel plate; A retaining steel plate is made up of some block plate matrixes, and the outer arc limit of steel matrix has longitudinal reinforcement draw-in groove radially, and inner arc one side of steel matrix has keyway shape bolt hole; Bolt hole is screwed with the bolt that is connected with two lining chassis external arc sections; A retaining steel plate inboard is provided with and the fixing arcuation reinforcing bar of two lining chassis sections, is uniformly distributed with on the reinforcing bar and is fixed with the reinforcing sleeve that radially is provided with, and reinforces and is provided with the reinforcing steel pipe that is positioned at a surperficial side behind the retaining steel plate in the sleeve; Be plugged with timber wedge between the surface after reinforcing steel pipe and keeping off a steel plate, a retaining steel plate external arc end face point is welded with zinc-plated steel plate for sealing water.During operation, all by the elongated overlap joint of code requirement, longitudinal reinforcement spacing, topping adhere to specification every plate two lining longitudinal reinforcements except that deformation joint, and the zinc-plated steel plate for sealing water of hoop accurately is in place by designing requirement simultaneously.
The utility model reasonable in design is reliable; Overcome existing secondary lining retaining head unit because unreasonable structure causes constuction joint place reinforcing bar to be prone to break off and waterproofing materials is installed problem not in place; The structure design of steel matrix has cushioned its stress deformation; And through reinforcing the steel pipe support fixation, waterproof effect is better, has that technology is simple, easy and simple to handle, recyclable material utilization and an advantage of practicing thrift cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: the 1-steel matrix, 2-longitudinal reinforcement draw-in groove, the 3-bolt hole, the 4-reinforcing bar, 5-reinforces sleeve, and 6-reinforces steel pipe, the zinc-plated steel plate for sealing water of 7-.
The specific embodiment
Metro built by mining method secondary lining pin-connected panel retaining head unit; Comprise an arcuation retaining steel plate; A retaining steel plate is made up of some block plate matrixes 1, and the outer arc limit of steel matrix 1 has longitudinal reinforcement draw-in groove 2 radially, and inner arc one side of steel matrix 1 has keyway shape bolt hole 3; Bolt hole 3 is screwed with the bolt that is connected with two lining chassis external arc sections; A retaining steel plate inboard is provided with and the fixing arcuation reinforcing bar 4 of two lining chassis sections, is uniformly distributed with on the reinforcing bar 4 and is fixed with the reinforcing sleeve 5 that radially is provided with, and reinforces and is provided with the reinforcing steel pipe 6 that is positioned at a surperficial side behind the retaining steel plate in the sleeve 5; Be plugged with timber wedge between the surface after reinforcing steel pipe 6 and keeping off a steel plate, a retaining steel plate external arc end face point is welded with zinc-plated steel plate for sealing water 7.In the practical implementation process; The two lining chassis terminations preset Φ 50 of 50cm at interval reinforce sleeve 5 and adopt Φ 42 to reinforce steel pipe 6 and reinforce; Reinforce sleeve 5 and adopt 4 connections of Φ 22 reinforcing bars to keep the 30mm spacing with chassis termination steel plate, keep off a steel plate and adopt Φ 22 bolts and two lining chassis termination steel plates to be connected fixing so that timber wedge is auxiliary to be reinforced.During use, two lining chassis are in place and check indexs such as center line, vault absolute altitude, lining cutting section, and qualified back block-by-block is installed steel matrix; Longitudinal reinforcement is accurately put into longitudinal reinforcement draw-in groove 2 can guarantee longitudinal reinforcement spacing and protective layer thickness; Bolt hole 3 is designed to prolate type structure, is beneficial to steel matrix 1 fine setting, with the suitably adjustment in allowed band of reply longitudinal reinforcement; Φ 22 bolts add packing ring fixation steel plate matrix 1, prevent that bolt occurs becoming flexible to collapse taking off phenomenon in the work progress; In the installation during buried zinc-plated steel plate for sealing water 7, with the zinc-plated steel plate for sealing water hoop of straight-plate-type of every joint 2m along a retaining steel plate crooked from bottom to up and at interval 50cm be spot welded on the retaining steel plate, guarantee arc and in divide and meet design requirement; Adopt 5cm plank piecemeal to open between longitudinal reinforcement, upstream face utilizes circumferential reinforcement to reinforce, and hoop cushioning lumps of wood overall fixed guarantees that longitudinal reinforcement and ectonexine rebar spacing meet design requirement; Utilize and reinforce a steel pipe and a timber wedge integral reinforcing retaining steel plate, guarantee not take place in the concrete work progress problem of phenomenons such as spillage, race mould, fried mould.
