Description
Technical field
The utility model belongs to technical field of building construction more particularly to a kind of shallow buried covered excavation Urban Underground pipe gallery.
Background technique
Urban Underground pipe gallery is infrastructure construction column emerging in recent years, it is intensive by various municipal pipelines
It lays and manages, improve the efficiency of management.Since the buried depth of piping lane is generally shallower, section is larger, applies when using shallow burial hidden digging
Working hour, it is necessary to be divided into multiple small pilot drives, while set up falsework.It is removed wait before applying two linings, then by falsework.
The installation and dismounting of falsework, not only very complicated, increases cost, and due to the limitation of falsework, cannot use
Engineering machinery seriously constrains excavation progress.
Utility model content
The purpose of the utility model is to provide a kind of shallow buried covered excavation Urban Underground pipe galleries, and falsework is avoided frequently to pacify
Dress is removed, and construction cost is reduced, and improves construction speed.
The utility model provides a kind of shallow buried covered excavation Urban Underground pipe gallery, and small including multiple step excavations is led
Hole, small pilot drive boundary and vertical mid-board overlapping position are equipped with more permanent vertical bracing members, permanently above and below vertical bracing members
Both ends respectively in small pilot tunnel preliminary bracing grid steel frame or steel arch-shelf connect；
Spiral net is equipped between adjacent permanent vertical bracing members, spiral net is connect with permanent vertical bracing members,
Permanent vertical bracing members form armored concrete mid-board, armored concrete mid-board, initial stage branch as skeleton casting concrete
Shield, secondary lining form Pipe rack.
Further, the quantity of permanent vertical bracing members is determined according to the size of vertical load.
Further, permanent vertical bracing members use H profile steel or double angle.
According to the above aspect of the present invention, by shallow buried covered excavation Urban Underground pipe gallery, using being configured at the permanent vertical of mid-board
Bracing members undertake construction loads, play the role of falsework, are directly poured in when pouring secondary lining concrete
In partition wall, while avoiding removing bracing members, the structural strength of mid-board is improved.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and can be implemented in accordance with the contents of the specification, below on the preferred embodiment of the present invention and the accompanying drawings in detail
It describes in detail bright as after.
Detailed description of the invention
Fig. 1 is the first Construction State figure of shallow buried covered excavation Urban Underground pipe gallery in an embodiment of the present invention；
Fig. 2 is the second Construction State figure of shallow buried covered excavation Urban Underground pipe gallery in an embodiment of the present invention；
Fig. 3 is the structural schematic diagram of completion shallow buried covered excavation Urban Underground pipe gallery in an embodiment of the present invention.
Figure label:
The leading pilot tunnel of 1-；Row pilot tunnel after 2-；3- preliminary bracing；The permanent vertical bracing members of 4-；5- secondary lining.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Join shown in Fig. 1 to 3, the present embodiment additionally provides a kind of shallow buried covered excavation Urban Underground pipe gallery, including multiple points
Walk the small pilot tunnel (the present embodiment is that double cabins piping lanes include leading pilot tunnel 1 and rear row pilot tunnel 2) excavated, small pilot drive boundary and perpendicular
Be equipped with more permanent vertical bracing members 4 to mid-board overlapping position, 4 upper and lower ends of permanent vertical bracing members respectively with small pilot tunnel initial stage
Grid steel frame or steel arch-shelf connection in supporting 3；
Spiral net is equipped between adjacent permanent vertical bracing members 4, spiral net and permanent vertical bracing members 4 connect
It connects, permanent vertical bracing members 4 are used as skeleton casting concrete, form armored concrete mid-board, armored concrete mid-board, just
Phase supporting 3, secondary lining 5 form Pipe rack.
Through the shallow buried covered excavation Urban Underground pipe gallery, while guaranteeing that piping lane excavates safe, it is entirely avoided existing
There are the work such as installation, dismounting and outward transport of falsework in pipe gallery, reduces labour cost while saving engineering material
With, and shorten and excavate circulation time, construction speed is accelerated, meanwhile, improve the structural strength of mid-board.
In the present embodiment, the quantity of permanent vertical bracing members 4 (every circulation of excavating is set up) is according to the size of vertical load
It determines.
In the present embodiment, permanent vertical bracing members 4 use H profile steel or double angle.
The construction procedure of double cabin piping lanes includes:
(1) according to piping lane ship cabin arrangement, entire excavated section is divided into two parts, two pilot tunnel step excavations are each led
The size in hole and position and cabin position consistency.
(2) leading pilot tunnel 1 excavates, and after the completion of excavating drilling depth every time, applies preliminary bracing 3, sets up permanent vertical bracing members 4
Vertical temporary construction bracket is formed, for bearing the vertical load in work progress, permanent vertical bracing members 4 must assure that perpendicular
Directly, vertical axis is overlapped with mid-board axis.
(3) row pilot tunnel 2 excavates afterwards, after the completion of each cyclic advance, applies preliminary bracing 3, sets up permanent vertical bracing members 4
Form vertical temporary construction bracket.
(4) after guide hole digging enough distances, 5 concrete of secondary lining is poured, in the permanent vertical bracing members 4 of mid-board
(fashioned iron) casting concrete forms armored concrete mid-board.
By the construction method, the entire section of piping lane is divided into corresponding small pilot drive, every circulation according to ship cabin arrangement
Permanent vertical bracing members are set at mid-board after the completion of excavation.It, will be during permanently vertical bracing members be used as when pouring secondary lining
Partition backbone is directly cast in concrete, a part as middle partition wall structure.While avoiding removing bracing members, improve
The structural strength of mid-board.
The above is only the preferred embodiment of the utility model, is not intended to limit the utility model, it is noted that
For those skilled in the art, without deviating from the technical principle of the utility model, it can also do
Several improvements and modifications out, these improvements and modifications also should be regarded as the protection scope of the utility model.
