Abstract
The utility model provides a tunnel support steel bar row mounting device based on a tunnel borer. The tunnel support steel bar row mounting device comprises a top protective shield arranged at the top of the tunnelling machine, wherein rectangular cavities used for accommodating to-be-mounted steel bar rows are distributed in the top protective shield along the peripheral direction of the cross section of a tunnel; each cavity penetrates through the top protective shield along the length direction of the tunnel; one end, adjacent to the rear part of the top protective shield, of the bottom of each cavity is provided with a mounting port used for putting the to-be-mounted steel bar row into the cavity and hooking the to-be-mounted steel bar row together with the mounted steel bar row. The tunnel support steel bar row mounting device has the advantages that the front and rear steel bar rows can constantly slide out from the tail of the top protective shield of the tunnelling machine while the tunnelling machine is used for tunnelling, so that a constant dense protective net is formed at the top of the tunnel; meanwhile, the steel bar rows slide out from the cavities of the top protective shield, so that the steel bar rows can be immediately fixed by use of a steel arch bridge after being discharged out from the protective shield, the steel bar rows are prevented from sinking entirely, furthermore top macadam of the tunnel is effectively prevented from collapsing, and a rapid and effective protection effect is achieved.
Description
Technical field
The utility model relates to a kind of tunnel machine, especially relates to a kind of tunnel support reinforcing bar row erecting device based on tunnel machine.
Background technology
Open type development machine is the large-scale machine for construction of underground tunnel, has safety, fast, efficient, the features such as environmental protection, and that in constructing tunnel, applies is more and more extensive.But any one engineering all can run into the operating mode that unfavorable geology, particularly tunnel top cave in work progress, not only can affect programming, return construction safety and impact.How fast and effeciently to perform preliminary bracing, the construction of development machine is had to material impact.Wherein reinforcing bar row's installation is exactly one of important means of preliminary bracing.
Utility model content
In order to solve reinforcing bar row mounting technique problem, the utility model provides a kind of tunnel support reinforcing bar row erecting device based on tunnel machine.By this device, in development machine work progress, can synchronously carry out reinforcing bar row's installation work, when running into tunnel top and occur caving in early warning, carry out rapidly reinforcing bar row's installation work, thereby effectively prevent that tunnel top from caving in, realize fast and safe construction.
The utility model in order to solve the problems of the technologies described above adopted technical scheme is: a kind of tunnel support reinforcing bar row erecting device based on tunnel machine, described supporting reinforcing bar row erecting device comprises the top shield that is arranged on development machine top, being circumferentially distributed with for placing reinforcing bar row's to be installed rectangular cavity along tunnel cross section in the shield of top, each described cavity all runs through top shield along length of tunnel direction, each cavity bottom is equipped with for place reinforcing bar row to be installed in cavity near the one end at shield rear portion, top, and by its with the installing port that reinforcing bar end exhausting part articulates has been installed.
Described cavity tilts to tunnel top at the rear portion of top shield.
Beneficial effect:
Use the utility model, can make development machine when tunneling, before and after making, reinforcing bar row can skid off from development machine top shield afterbody incessantly, the reinforcing bar row who skids off fixes once going out the available steel arch frame of shield, effectively prevent that reinforcing bar row from sinking, at tunnel top, form continuously intensive protective screening, effectively stop that top, tunnel rubble caves in, and reaches supporting effect fast and effectively.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to further concrete detailed explanation.
As shown in the figure, a kind of tunnel support reinforcing bar row erecting device based on tunnel machine
,described development machine is provided with top shield 2, on top shield 2, along tunnel axis direction, running through whole top shield 2 is provided with for depositing reinforcing bar row's 4 to be installed rectangular cavity 3, the width of cavity 3 and height adapt with the reinforcing bar row's that will install size, can hold reinforcing bar, arrange and facilitate it from cavity 3, to be hauled out and be advisable; Described cavity 3 is a plurality of, along circumferentially distributing successively of tunnel cross section, in the bottom of each cavity 3, be provided with for arranging 4 to the interior placement of cavity 3 reinforcing bar to be installed, and by its with the installing port 5 that reinforcing bar end exhausting part articulates has been installed, installing port 5 is arranged on cavity 3 near the position of top shield tail end, for the reinforcing bar row to be installed who makes to skid off from cavity 3 is adjacent to tunnel top better, described cavity 3 tilts to tunnel top at the afterbody of top shield 2
Cavity 3 can start to tilt to tunnel top from the edge near top shield tail end from installing port 5, so both can guarantee that reinforcing bar row to be installed can skid off smoothly from cavity, can make again it be adjacent to better tunnel top, further to guarantee the installation effect of the elementary protection of reinforcing bar row net.
In one end of reinforcing bar to be installed row 4, be provided with and for hook, reinforcing bar be installed and arranged the hook 8(of 6 afterbodys and come off for preventing, hook 8 can weld with electric welding), when development machine tunnels forward, the reinforcing bar row 4 to be installed of leaving 3 li of cavitys in is installed reinforcing bar row 6 drives and is skidded off from the afterbody of top shield 2, then by steel arch frame 7(steel arch frame, be the conventional part in tunnel excavation preliminary bracing, set up in advance) be fixed on tunnel top.
During the utility model work, first with manually first group of reinforcing bar row (being now reinforcing bar row to be installed) inserted respectively to each cavity 3 of top shield by installing port 5, then this being organized to all reinforcing bars sends discharged to top shield 2 afterbodys, with steel arch frame 7, all reinforcing bar rows' afterbody is pressed abd fixed on to tunnel top again, then, development machine tunnels forward, reinforcing bar row is because compressed afterbody by steel arch frame 7, thereby by the whole top shield 2 of taking out of, and arrange net at the densely covered reinforcing bar of tunnel top formation covering tunnel top, when reinforcing bar row's stem arrives installing port 5 position of erecting device, first group of reinforcing bar row installs (reinforcing bar after installing is lined up as reinforcing bar row is installed), now, to cavity front end, insert second group of reinforcing bar row (being now reinforcing bar row to be installed), and the hook of second group of reinforcing bar end exhausting part 8 is hung on the dowel of first group of reinforcing bar row stem (reinforcing bar row has been installed) end.Development machine continues driving forward, then second group of reinforcing bar row is hauled out to top shield 2, continues with steel arch frame 7 fixing.Circulation so again and again, forms continuously reinforcing bar row net at tunnel top, plays the effect that prevents that rubble from caving in.
