多轴钻机及其施工方法 Multi-axis drilling rig and its construction method

技术领域 FIELD

本发明涉及一种在土木建筑等工程中钻削地层、构筑等厚地下连续墙的多轴钻机及其施工方法。 The present invention relates to a multi-shaft drilling rig and its construction method of formation in the civil engineering and construction, and the like constructing the underground continuous wall thickness.

背景技术 Background technique

目前,为人们所公知的技术之一,是一种使用多轴钻机构筑柱列式地下连续墙的技术:它是由专用的多轴钻机,驱动一组钻杆,分段钻进地层至一定深度后提升回地面,在一组钻杆钻进或提升的过程中,可从钻头端部向土壤中注入水泥浆,与被钻头钻松散的土壤混合搅拌,构筑成一段水泥土墙体;然后再进行下一段水泥土墙体的施工,并使相邻的两段墙体彼此有一定的重合搭接;重复上述施工,即可构筑成一条地下水泥土墙体;在水泥土墙体固化之前,可以插入型钢等来提高墙体的强度,水泥土墙体固化后,便造成了一条柱列式的地下连续墙。 Currently, it is one of the techniques well-known, is a multi-shaft drilling rig constructed using column row diaphragm wall technique: it is composed of special multi-axis drilling machine, a set of driving drill, drilling the formation to a certain segment to enhance the depth of back ground, the drill pipe during drilling, or a set of lift, the end portion may be injected from the drill bit into the soil slurry, mixed with the drill bit loose soil stirring, constructed as a soil cement wall section; and then the construction period of the soil cement wall, and two adjacent walls have overlaps overlapping one another; repeating the above construction, dirt can build into an underground wall; soil cement wall before curing, steel can be inserted to increase the strength of the wall, the wall of soil cement after curing, will result in a post-column diaphragm wall.

使用上述多轴钻机构筑柱列式地下连续墙的技术存在的主要缺点是:造成的墙体是非等厚、呈葫芦串形状的(参见图6),厚度不一,强度不均匀;特别是作为防渗墙使用时,墙体的尖角处容易发生渗漏水现象;而且插入型钢的排列和数量也受到制约。 Constructed using the multi-axis drilling machine main drawback column column diaphragm wall technique are: non-uniform thickness due to the wall, as a string gourd shape (see FIG. 6), of varying thickness, uneven strength; in particular as when using cutoff wall, the wall is likely to occur at sharp corners water leakage; and insert arrangement and the number of steel is also restricted.

为克服上述技术的缺点,日本专利(特开平6-235219)公开了一种多轴钻机,其特点是在钻杆和与其轴线垂直的旋转轴上设置了一对相互啮合的螺旋齿轮,在旋转轴上还设有一个切削刀盘;当钻杆旋转时,通过螺旋齿轮传递钻杆的动力,由旋转轴带动切削刀盘旋转,可削平柱列式连续墙体的尖角部分,使墙体厚度一致。 To overcome these technical drawbacks, Japanese Patent (JP-6-235219) discloses a multi-axis drilling machine, characterized by a rotating shaft perpendicular to its axis and the drill is provided one pair of helical gears meshing with each other, the rotation There is also a shaft cutter disks; when the drill pipe is rotated, power is transmitted via the helical gear drill rod, driven by a rotary shaft of the cutting disk rotates, the flattened portion of the post-row angular continuous wall, so that the wall uniform thickness. 但这一技术仍然存在如下不足和缺点:1、采用螺旋齿轮传动,需用滚动轴承支撑、并需要润滑和密封等,结构复杂,加工制造成本高。 However, this technique still has the following deficiencies and shortcomings: 1, spiral gear, bearing support required, and the need for lubrication and sealing, complex structure and high manufacturing costs.

2、当钻杆在地下钻削时,密封件易磨损,泥水土砂侵入齿轮传动部位后容易造成传动装置损坏,影响正常施工,维护修理工作量大。 2, when drilling in the ground the drill pipe, seal wear, mud earth and sand invades the gear portion is likely to cause damage to the transmission, affecting the normal construction, maintenance and repair workload.

3、由于螺旋齿轮传动结构复杂占有空间大,当钻杆在地下钻削时,该部位阻碍土砂流动,增加钻削时的阻力,使工作效率降低。 3, due to the complex structure of the helical gearing large occupied space, the drill pipe when drilling in the ground, the earth and sand flow obstruction site, increased resistance during drilling, so that reduced efficiency.
