Abstract
The utility model belongs to equipment for supporting of underworkings of tunnels and coal mines, and particularly relates to a pipe roof supporting device, which mainly resolves the technical problems that conventional supporting methods cannot support roadways timely and effectively so as to cause large-area inbreak of the roadways, affect construction quality and construction progress and bring great safety threats to construction workers. The technical scheme includes that the pipe roof supporting device comprises a ladder beam and a plurality of iron pipes arranged in the ladder beam, and the ladder beam is fixed to an anchor rope through an anchor rod. Supporting strength and effective supporting area are increased by means of strength of the iron pipes, advancing progress is quickened, rock breaking caused by inbreak of roof plates can be effectively prevented, and thereby safety of constructors can be guaranteed.
Description
Technical field
The utility model belongs to roadway support device under tunnel and the coal mine, is specifically related to a kind of pipe shed support device.
Background technology
In tunnel and the Mine Tunnel Construction process, structural belt or top board weakness own appear in the top board condition, when loose, the at present domestic supporting method that generally adopts mainly contains leading grouting with small pipe, bassoon canopy, deep hole grouting, horizontal jet grouting stake, horizontal agitation pile and horizontal frozen etc.Because of being subjected to the restriction of conditions such as construction environment, supporting method commonly used has limitation very, can not carry out supporting to the tunnel timely and effectively, causes tunnel occurrence of large-area inbreak, directly influence workmanship and construction speed, and the constructor is caused great security threat.
Summary of the invention
The utility model is primarily aimed at supporting method commonly used can not carry out supporting to the tunnel timely and effectively, cause tunnel occurrence of large-area inbreak, influence workmanship and construction speed, and the constructor caused the technical problem of great security threat, and a kind of pipe shed support device that can effectively prevent large stretch of roof collapse fractured rock is provided.
The utility model is to address the above problem the technical scheme of taking to be:
A kind of pipe shed support device comprises ladder beam and the some iron pipes that are arranged in the ladder beam, and described ladder beam is fixed by anchor pole and anchor cable.
The utility model adopts technique scheme, utilizes the intensity and the effective area of the intensity increase supporting of iron pipe, has accelerated the progress of driving, effectively prevents large stretch of roof collapse fractured rock, has guaranteed constructor's safety.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of pipe shed support device comprises ladder beam 1 and the some iron pipes 2 that are arranged in the ladder beam 1, and described ladder beam 1 is fixing by anchor pole 3 and anchor cable 4.
Mounting method of the present utility model: ladder beam 1 is fixed in the tunnel, adopts a word alloy bit to join perforating on the wall of hollow hexagonal steel in two ladder beams, boring is squeezed into iron pipe 1 in the boring, and is guaranteed that the protruded length of iron pipe is at least 1mm; The outside of ladder beam 1 is fixed on the top, tunnel with anchor pole 3 and anchor cable 4, adopts the many endless form drivings of shallow eye.
