Description

复合型围护桩结构 技术领域
本发明属于建筑工程技术领域，涉及一种复合型围护桩结构。
背景技术
水泥土搅拌桩是用于加固饱和软黏土低地基的一种方法，它利用水泥作为固化剂，通过特制的搅拌机械，在地基深处将软土和固化剂强制搅拌，利用固化剂和软土之间所产生的一系列物理化学反应，使软土硬结成具有整体性、水稳定性和一定强度的优质地基。钻孔桩是指在工程现场通过机械钻孔、钢管挤土或人力挖掘等手段在地基土中形成桩孔，并在其内放置钢筋笼、灌注混凝土而做成的桩。
上述的两种桩由于具有成本低、制作速度高等优点，但其稳定性和强度不如预制桩。
专利号为200720302293.4的中国发明公开了一种企口混凝土T形桩，具有T形桩本体，所述本体的横截面呈“T”形，该本体两边翼缘设有榫槽连接件。将该T形桩应用于河道护岸后，护岸内侧土体内含的水分排出速度较慢，影响护岸的稳定性。
专利号为201420121343.9的中国发明公开了一种透水T形桩，包括第一面板和腹板，两者一体浇筑构成T形，所述第一面板上设有若干以其中心线为对称轴对称布置的、采用透水混凝土浇筑形成的透水区，各透水区内均开设若干垂直于第一面板所在平面、且用于栖养螺蛳的盲孔。
上述方案采用T形桩修建河道护岸时，大大提高了由该T形桩所成护岸的抗冲刷、抗倾覆能力，稳定性更好。但是该T形桩缺乏与其他建筑构件连接的结构，因此稳定性有待加强。
发明内容
本发明的目的是针对上述问题，提供一种能用于建筑构件并提高建筑构件强度的复合型围护桩结构。
为达到上述目的，本发明采用了下列技术方案：一种复合型围护桩结构，包括横截面呈T形的T形桩，还包括轴心线与T形桩平行的复合桩，所述的T形桩上设有若干锚杆，且锚杆一端与T形桩固定连接，另一端插入到复合桩中并与复合桩形成固定连接。
在上述的种复合型围护桩结构中，所述的复合桩为水泥土搅拌桩或钻孔桩，所述的T形桩包括相互连接的横向板和纵向板。
在上述的种复合型围护桩结构中，所述的纵向板的一侧固定连接横向板的中部，纵向板与横向板之间的夹角为90°。
在上述的种复合型围护桩结构中，所述的纵向板远离横向板的一侧与复合桩紧贴或进入到复合桩内部。
在上述的种复合型围护桩结构中，所述的T形桩内并沿T形桩的轴向设有钢筋笼，且钢筋笼的横截面为T形。
在上述的种复合型围护桩结构中，所述的钢筋笼包括若干相互平行并沿T形桩的轴向设置的钢棒，及沿T形桩的周向设置的并与钢棒固定连接的连接筋。
在上述的种复合型围护桩结构中，所述的T形桩的端部具有凹凸连接机构，当两个相邻的T形桩靠近时，两个T形桩能通过凹凸连接机构形成卡接配合。
在上述的种复合型围护桩结构中，所述的凹凸连接机构包括设置在横向板相对置的两个侧面上的凹槽和凸条，所述的凹槽和凸条相配适，当两个相邻的T形桩相互靠近时，其中一个T形桩上的凸条能插入到另一个T形桩上的凹槽中从而使两个T形桩能卡接配合。
在上述的种复合型围护桩结构中，所述的凹凸连接机构包括分别设置在横向板两侧的连接块，两个连接块沿横向板的轴心线呈中心对称。
在上述的种复合型围护桩结构中，所述的连接块具有凹孔和凸块，所述的凸块与凹孔相配适，且其中一个连接块上的凸块能插入到另一个连接块上的凹孔中从而使两个相邻的T形桩能卡接配合。
与现有的技术相比，本发明的优点在于：T形的桩体稳定性高，适用于围护地下室、水泥土搅拌桩或钻孔桩，从而提高地下室、水泥土搅拌桩或钻孔桩的强度，锚杆使桩体与水泥土搅拌桩或钻孔桩的连接，进一步提高桩体的强度和稳定性，凹凸连接机构能使两个T形桩之间实现快速的密封连接；两个T形桩能形成相互卡接配合，从而形成稳定的围护桩结构。

具体实施方式
下面结合附图和具体实施方式对本发明做进一步详细的说明。
实施例1
如图1所示，一种复合型围护桩结构，包括横截面呈T形的T形桩1，还包括轴心线 与T形桩1平行的复合桩2，所述的T形桩1上设有若干锚杆3，且锚杆3一端与T形桩1固定连接，另一端插入到复合桩2中并与复合桩2形成固定连接，如图2所示，所述的T形桩1包括相互连接的横向板11和纵向板12。如图3所示，锚杆3有若干个且位于纵向板12的两侧，优选，位于纵向板12两侧的锚杆3均匀分布。为了加强锚杆3的固定效果，横向板11内还固定有与横向板11的轴心线平行的连接棒31，该连接棒31与锚杆3固定连接并呈90°的夹角。
复合桩2为水泥土搅拌桩或钻孔桩，水泥土搅拌桩是用于加固饱和软黏土低地基的一种方法，它利用水泥作为固化剂，通过特制的搅拌机械，在地基深处将软土和固化剂强制搅拌，利用固化剂和软土之间所产生的一系列物理化学反应，使软土硬结成具有整体性、水稳定性和一定强度的优质地基。钻孔桩是指在工程现场通过机械钻孔、钢管挤土或人力挖掘等手段在地基土中形成桩孔，并在其内放置钢筋笼、灌注混凝土而做成的桩。
纵向板12的一侧固定连接横向板11的中部，纵向板12远离横向板11的一侧与复合桩2紧贴或进入到复合桩2内部，紧贴是为了进一步提高复合桩2与T形桩1之间的支撑强度，纵向板12与横向板11之间的夹角为90°，优选地，纵向板12和横向板11为一体成型。
T形桩1内并沿T形桩1的轴向设有钢筋笼4，且钢筋笼4的横截面为T形。钢筋笼4包括若干相互平行并沿T形桩1的轴向设置的钢棒41，及沿T形桩1的周向设置的并与钢棒41固定连接的连接筋42，连接筋42可以是螺旋形或是圈型，与钢棒41的固定方式可以是焊接或捆绑连接等等。
T形桩1的端部具有凹凸连接机构5，当两个相邻的T形桩1靠近时，两个T形桩1能通过凹凸连接机构5形成卡接配合。在本实施例中，凹凸连接机构5包括设置在横向板11相对置的两个侧面上的凹槽51和凸条52，所述的凹槽51和凸条52相配适，当两个相邻的T形桩1相互靠近时，其中一个T形桩1上的凸条52能插入到另一个T形桩1上的凹槽51中从而使两个T形桩1能卡接配合。凹槽51和凸条52可以是不同的形状，能形成卡接和凹凸连接即可，如图4和图8所示，凹槽51和凸条52为矩形，如图5和图9所示，凹槽51和凸条52为楔形，如图6和图10所示，凹槽51和凸条52为扇形或圆缺形。
本发明可以用于地下室100建造，在建造地下室100时，先把复合桩2打入到地下的土层101中，再把T形桩1打入到地下并与复合桩2形成连接，T形桩1通过凹凸连接机构5并围成圈型，围护在需要挖掘的地下室100周围，这样，一个性能良好的围护桩就形成了。在T形桩1相互连接的凹凸连接机构5中可以加入密封材料如环氧树脂，提高防水性，凹凸连接机构5起到相互咬合的作用，相当于起到加强筋的作用。锚杆3与地下室周围的水泥土搅拌桩或钻孔桩形成连接时，则能形成相互固定连接的结构，从而提升整个结构的稳定性。当然，本发明也不限用于地下室的建造，也可用于河堤，桥梁等。
实施例2
本实施例与实施例1的结构和工作原理基本相同，不同之处在于，如图7和图11所示，凹凸连接机构5包括分别设置在横向板11两侧的连接块53，两个连接块53沿横向板11的轴心线呈中心对称。连接块53具有凹孔54和凸块55，所述的凸块55与凹孔54相配适，且其中一个连接块53上的凸块55能插入到另一个连接块53上的凹孔54中从而使两个相邻的T形桩1能卡接配合。图7中的连接块53呈挂钩型，连接方便且牢固。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
