Description

刚柔结合支护结构
技术领域
本发明涉及巷道支护领域，尤其刚柔结合支护结构。
背景技术
在我国，随着煤矿开采深度的加深，以及隧道所需支护不断加大，冲击地压的破坏也再加剧，现有的支护方式大多都是静态围岩压力下的支护结构，很难应对当前的抗冲支护难题，因为又必须提出一些新的支护方式，虽然截止目前，有许多学者提出了不少的应对措施，但是这些措施，要么是支护效果理想，但是成本大幅度提高，要么就是达不到支护的理想效果。
发明内容
本发明所要解决的问题是提供一种成本不高，且抗冲效果好的支护结构。
本发明所采用的技术方案是：
刚柔结合支护结构，由弧U型钢、直U型钢、U型钢卡缆、钢索、枕木、底板组成；弧U型钢布置在巷道顶部，直U型钢布置在巷道两侧壁，所述的弧U型钢与直U型钢通过U型钢卡缆连接；弧U型钢、直U型钢与巷道的围岩之间布置有枕木；弧U型钢和直U型钢的U型槽开口朝向枕木；底板铺设在巷道底部；所述钢索首尾连接围成巷道横截面的形状，分布在弧U型钢的U型槽内、直U型钢的U型槽内以及底板下边。
本发明提供的刚柔结合支护结构，U型钢起到刚性支护的作用，当冲击载荷破坏U型钢时，其内部的钢索起到柔性支护作用，从刚性支护到柔性支护的过渡阶段，就是该支护结构对冲击载荷的缓冲作用，从而起到抗冲的效果。
附图说明
图1是本发明结构简图；
图2是U型钢与钢索的布置示意图。
具体实施方式
下面结合附图与具体实施例对本发明进行详细说明。
如图1和图2所示，刚柔结合支护结构，由弧U型钢1、直U型钢2、U型钢卡缆3、钢索4、枕木5、底板6组成；弧U型钢1布置在巷道顶部，直U型钢2布置在巷道两侧壁，所述的弧U型钢1与直U型钢2通过U型钢卡缆3连接；弧U型钢1、直U型钢2与巷道的围岩7之间布置有枕木5；弧U型钢1和直U型钢2的U型槽开口朝向枕木5；底板6铺设在巷道底部；所述钢索4首尾连接围成巷道横截面的形状，分布在弧U型钢1的U型槽内、直U型钢2的U型槽内以及底板6下边。
首先将一定长度的钢索4首尾连接布置在弧U型钢1与直U型钢2的U型槽内，将弧U型钢1与直U型钢2按照要求的距离架设在巷道内部，然后将枕木5按照要求的间距布置在围岩7与弧U型钢1、直U型钢2之间，架设完成后，在地面上的钢索4上铺设巷道底板6。
以上仅是本发明的具体应用范例，对本发明的保护范围不构成任何限制。凡采用等同变换或者等效替换而形成的技术方案，均落在本发明权利保护范围之内。
