Description
Technical field
The utility model relates to the roadway support technical field, relates in particular to the roadway support structure that adopts U-shaped frame.
Background technology
At present, along with growing continuously and fast of Chinese national economy, particularly the demand of coal resources is increasing to the energy, and the superficial part coal resources are progressively deficient, and China's coal-mine exploits particularly that the mining area, east has entered the deep mining category mostly.The reserves of coal resources in China buried depth below 1000m have 2.95 * 1012t, account for 53% of coal resources in China gross reserves greatly.According to incompletely statistics, China had and hundreds of the pit mining degree of depth was surpassed 1000m present stage, wherein, the Zhao Gezhuan of Luan office opens a mine, the Sun Cun colliery of new river in Shangdong Province office, mines such as Hua Feng colliery are adopted and are reached 1300m deeply, simultaneously, China's average mining depth in state-owned emphasis colliery increases year by year with the speed of 10～25m/a, expectation will have more collieries to enter the mining depth scope of 1000～1500m in following 20 years China, corresponding is because the complexity day by day of mining conditions and the continuous increase of the degree of depth with it, increasing deep tunnel presents the feature of soft-rock tunnel, this has very large difference with adopting traditional support pattern and method, and some do not occur in the superficial part recovery process or very few engineering project disaster problem that occurs also displays in more tangible mode in deep mining simultaneously.Deep tunnel country rock body is under high ground temperature, the high-stress state, presented the soft rock characteristic that tangible large deformation ground is pressed and continued rheology for a long time, this has higher requirement to well lane engineering construction and support technology, and deep tunnel supporting problem also more and more becomes one of difficult problem of deep mining.
From domestic and foreign literature, up to the present still there are not means in full force and effect to solve the difficult supporting difficult problem of Deep Soft Rock Tunnel large deformation both at home and abroad, this mainly is owing to the continuous increase along with the coal mining degree of depth, high ground temperature, highland are pressed and are manifested obviously, stress of primary rock redistribution, occur stress in the roadway surrounding rock and concentrate, also there are many unknown solutions in its deep tunnel failure mechanism of while etc., and these all make the deep tunnel support technology become a big technical barrier of deep mining engineering.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of U-shaped scaffolding structure body roadway support structure, can effectively reduce the moderate finite deformation in tunnel.
For achieving the above object, embodiment of the present utility model adopts following technical scheme:
A kind of U-shaped scaffolding structure body roadway support structure comprises:
At least two U-shaped frames, supporting is in the tunnel spaced reciprocally;

Locker is arranged on the junction of described channel-section steel and U-shaped frame, and described channel-section steel is fixed on the described U-shaped frame, forms U-shaped scaffolding structure body.
Wherein, the two ends of described channel-section steel offer notch respectively; In the intersection of described steel tank and U-shaped frame, the notch of opening on the channel-section steel and the interlock of U-shaped frame phase.
Wherein, the cross section of described U-shaped frame is V-shaped; The notch of opening on the described channel-section steel is V-shaped, and described U-shaped frame is stuck in the V-type notch on the described channel-section steel.
Wherein, the distance on the bottom of described notch and channel-section steel base is 30mm.
Wherein, described locker is the straightway composition that a semi arch adds two ends.
The U-shaped frame roadway support structure that the utility model embodiment provides, couple together respectively with shank and the top of channel-section steel with adjacent U-shaped frame, each U-shaped frame is worked no longer separately, but play support action with an integral body, so can better resist the shoulder in tunnel and the distortion at base angle, thereby can effectively reduce the moderate finite deformation in tunnel.

The specific embodiment
Below in conjunction with accompanying drawing a kind of U-shaped frame roadway support structure of the utility model embodiment is described in detail.
Should be clear and definite, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtain under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Figure 1 and Figure 2, the utility model embodiment provides a kind of U-shaped frame roadway support structure, comprising: at least two U-shaped frames 1, and supporting is in the tunnel spaced reciprocally; Channel-section steel 2 is connected shank and/or the top of two adjacent U-shaped frames; Locker 3 is arranged on the junction of described channel-section steel and U-shaped frame, and described channel-section steel is fixed on the described U-shaped frame.
The U-shaped frame roadway support structure that the utility model embodiment provides, couple together respectively with shank and the top of channel-section steel with adjacent U-shaped frame, each U-shaped frame is worked no longer separately, but play support action with an integral body, so can better resist the shoulder in tunnel and the distortion at base angle, thereby can effectively reduce the moderate finite deformation in tunnel.
Referring to shown in Figure 4, be connected stablely more and firmly in order to make between channel-section steel 2 and the U-shaped frame 1, offer notch 21 respectively at the two ends of described channel-section steel 2; In the intersection of described steel tank and U-shaped frame, the notch of opening on the channel-section steel 21 and U-shaped frame 1 phase interlock.
