地下室按埋入地下深度的不同，可分为：1、全地下室；2、半地下室。全地下室是指地下室地面低于室外地坪的高度超过该房间净高的1/2；半地下室是指地下室地面低于室外地坪的高度为该房间净高的1/3-1/2。地下室一般用作高层建筑的地下停车库、设备用房，结构可做成一层或二、三层、多层地下室。当地下室埋入深度较深时或结构有多层时，其稳定性和可靠性需要得到保证。
中国专利文献公开了一种地下室[公告号：CN 104250976A]，所述地下室外墙包括两块先浇混凝土墙板和一由所述两块先浇混凝土墙板之间的间隙构成的后浇带，所述地下室外墙上靠近所述后浇带的外侧处设有一挡墙，用于先期防水和挡土，并形成一道永久性附加防水层。该地下室具有施工方便、施工周期短、施工费用低以及防水性能好等特点。但是仔细观察不难发现，该方案地下室外墙需要在连接缝处进行现浇，地下室外墙与地下室的楼层之间也没有牢固的结合方式，不能形成一体式结构，造成该地下室的强度受到影响。
发明内容
本发明的目的是针对上述问题，提供一种结构稳定，性能良好的用围护桩连接的地下室结构。
为达到上述目的，本发明采用了下列技术方案：一种用围护桩连接的地下室结构，包括若干横截面呈T形的围护桩，所述的围护桩两端依次连接并合围在地下室的周围从而形成框型的围护机构，所述的地下室内部设有地下室楼层且地下室楼层与围护桩固定连接。
在上述的用围护桩连接的地下室结构中，所述的围护桩远离地下室的一侧还设有水泥土搅拌桩，且所述的水泥土搅拌桩与围护桩固定连接，所述的水泥土搅拌桩包围在围护桩形成的框型的围护机构外部。
在上述的用围护桩连接的地下室结构中，所述的围护桩包括横向桩和与横向桩垂直并固定连接的竖向桩，在横向桩上设有能使地下室楼层与横向桩相连接的连接件结构，竖向桩插入到水泥土搅拌桩内与水泥土搅拌桩固定连接。
在上述的用围护桩连接的地下室结构中，所述的连接件结构包括若干固定在横向桩内的连接螺母，所述的地下室楼层中的钢筋能与连接螺母固定连接从而使地下室楼层与围护机构固定连接。
在上述的用围护桩连接的地下室结构中，所述的连接螺母底部具有卡台，围护桩内部具有与连接螺母的卡台卡接配合的连接棒且连接棒与围护桩固定连接，连接螺母与连接棒一一对应。
在上述的用围护桩连接的地下室结构中，与地下室楼层的位置相对应的连接螺母上设有连接筋且连接筋插入到地下室楼层内部并与地下室楼层固定连接。
在上述的用围护桩连接的地下室结构中，所述的横向桩上固定有若干锚杆，所述的锚杆插入到水泥土搅拌桩内并与水泥土搅拌桩固定连接。
在上述的用围护桩连接的地下室结构中，所述的锚杆位于竖向桩两侧并均匀分布，且在横向桩内还固定有用于连接锚杆的锚杆固定杆，所述的锚杆固定杆与锚杆垂直。
在上述的用围护桩连接的地下室结构中，所述的横向桩的两端具有能让两个相邻的围护桩沿横向桩的径向密封连接的密封机构。
在上述的用围护桩连接的地下室结构中，所述的密封机构包括凸出横向桩一端的凸条和向横向桩另一端凹进的凹槽，所述的凸条和凹槽的形状、大小相配适。
与现有的技术相比，本发明的优点在于：围护桩能与土层及地下室楼层牢固结合，水泥土搅拌桩对围护桩进一步起到支撑作用，从而于地下室楼层形成稳定的支撑结构；当围护桩合围在地下室周围时，对地下室能起到防水及整体支撑的效果，从而使整个地下室处于稳定的结构中。

再结合如图1所示，围护桩1内还设有钢筋笼机构1a，用于加强围护桩1的强度。围护桩1包括横向桩6和与横向桩6垂直并固定连接的竖向桩7，竖向桩3与横向板2相交形成T形，在横向桩6上设有能使地下室楼层4与横向桩6相连接的连接件结构8，竖向桩7插入到水泥土搅拌桩5内与水泥土搅拌桩5固定连接。竖向桩3插入到水泥土搅拌桩5内部形成固定连接。
如图12所示，连接件结构8包括若干固定在横向桩6内的连接螺母9，如图6所示，地下室楼层4中的钢筋4a能与连接螺母9固定连接从而使地下室楼层4与围护机构3固定连接，也即钢筋4a可以与连接螺母9螺接或焊接形成固定连接。
优选方案，连接螺母9底部具有卡台10，围护桩1内部具有与连接螺母9的卡台10卡接配合的连接棒11且连接棒11与围护桩1固定连接，连接螺母9与连接棒11一一对应。连接棒11位于连接螺母9内的端部具有凸台11a，凸台11a与卡台10相配适从而使凸台11a能卡在卡台10上，实现连接螺母9与连接棒11卡接配合，再结合图5和图6所示，与地下室楼层4的位置相对应的连接螺母9上设有连接筋12且连接筋12插入到地下室楼层4内部并与地下室楼层4固定连接。

再结合图4和图6所示，连接螺母9沿横向桩6的径向和轴向均匀分布从而形成矩形阵列，便于配合不同层高的地下室楼层4，当然，也可以通过计算得到横向桩6的连接螺母9的位置，如根据两个地下室楼层4之间的距离可以推算出分别与两个地下室楼层4连接的连接螺母9的位置。
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2和图3所示，横向桩6上固定有若干锚杆13，所述的锚杆13插入到水泥土搅拌桩5内并与水泥土搅拌桩5固定连接。锚杆13位于竖向桩7两侧并均匀分布，且在横向桩6内还固定有用于连接锚杆13的锚杆固定杆14，所述的锚杆固定杆14与锚杆13垂直。结合图4所示，锚杆13插入到水泥土搅拌桩5中与水泥土搅拌桩5固定连接，进一步提高围护桩1与水泥土搅拌桩5的结合度。
实施例3
本实施例与实施例1和/或2的结构和工作原理基本相同，不同之处在于，本实施例中的围护桩由若干个围护桩1沿轴向相互连接而成。如图8所示，两个围护桩本体1用螺栓18连接，如图9所示，两个围护桩1用连接件19连接，如图10所示，两个围护桩1焊接固定。本实施例中所述的连接件102在本申请人之前申请的专利“无剪切快速强拉对接 扣件及对接件[申请号：200810060180.7]”及“多头快速强拉对接扣件及预制件[申请号：200810060181.1]”中有详细记载，因此不做赘述。
