Description
技术领域technical field
本发明涉及咬合桩室内试验技术领域,特别是涉及一种圆形咬合桩的制样装置。The invention relates to the technical field of indoor tests of occlusal piles, in particular to a sample preparation device for circular occlusal piles.
背景技术Background technique
咬合桩是荤桩与素桩互相咬合排列形成的一种基坑围护结构,具有良好的支护与防渗作用。其中,圆形咬合桩在基坑开挖时能够产生“土拱效应”,充分调动土体的自稳能力,从而减少咬合桩受到的土压力,达到较好的变形控制效果。因此,圆形咬合桩在工程实践中被越来越多的使用。The occlusal pile is a foundation pit enclosure structure formed by the interlocking arrangement of meat piles and plain piles, which has good support and anti-seepage effects. Among them, the circular occlusal pile can produce a "soil arch effect" during the excavation of the foundation pit, which can fully mobilize the self-stabilizing ability of the soil, thereby reducing the earth pressure on the occlusal pile and achieving a better deformation control effect. Therefore, circular occlusal piles are used more and more in engineering practice.
圆形咬合桩理论研究滞后于实践。在圆形基坑中,咬合桩受力及变形的机理尚未完全了解,尤其在咬合桩设计时只考虑素桩的止水效果,未考虑素桩抵抗土压力的贡献,这样的设计往往造成不必要的工程浪费。目前关于圆形咬合桩的主要成果多见于施工工法、施工工艺、超缓凝剂的研发和数值仿真等,严重缺乏试验数据的支撑。Theoretical research on circular occlusal piles lags behind practice. In circular foundation pits, the mechanism of force and deformation of occlusal piles has not been fully understood, especially in the design of occlusal piles, only the water-stop effect of plain piles is considered, and the contribution of plain piles to resist earth pressure is not considered. Necessary engineering waste. At present, the main achievements of circular occlusal piles are mostly found in the construction method, construction technology, research and development of super retarder and numerical simulation, etc., which are seriously lacking in the support of experimental data.
由于现场试验条件和所处环境复杂,影响因素较多,故室内试验是圆形咬合桩理论研究的重要手段之一。在室内试验中,现有研究主要针对圆形咬合桩的一部分,即少量的单桩咬合,现有技术还不能制备完整的圆形咬合桩试样,使得理论研究的深度和精度受到限制。Due to the complex field test conditions and environment, and many influencing factors, the indoor test is one of the important means for the theoretical research of circular occlusal piles. In the laboratory test, the existing research mainly focuses on a part of the circular occlusal pile, that is, a small amount of single pile occlusal. The existing technology cannot prepare a complete circular occlusal pile sample, which limits the depth and accuracy of theoretical research.

利用本实施例圆形咬合桩的制样装置制样圆形咬合桩的具体实施步骤如下:Utilize the sample preparation device of the circular occlusal pile of the present embodiment to prepare the sample circular occlusal pile The specific implementation steps are as follows:
(1)利用吊车将底座41放置在混凝土振动台上;(1) Utilize a crane to place the base 41 on the concrete vibrating table;
(2)利用吊车将内筒42放置在底座41对应的导线槽14上,导线槽14的深度为5mm,通过编号保证内筒42底端的定位孔25与底座41上的定位螺栓13对准,定位螺栓13围绕底座41中心呈角度分布,内筒42的外壁需涂上脱模剂,便于后期脱模。(2) Utilize a crane to place the inner cylinder 42 on the wire groove 14 corresponding to the base 41. The depth of the wire groove 14 is 5 mm. Ensure that the positioning holes 25 at the bottom of the inner cylinder 42 are aligned with the positioning bolts 13 on the base 41 by numbering. The positioning bolts 13 are angularly distributed around the center of the base 41, and the outer wall of the inner cylinder 42 needs to be coated with a release agent to facilitate later demoulding.
(3)利用吊车将外筒43放置在底座41对应的导线槽14上,对底座41上的固定螺丝12和底端护环44上的螺丝46孔进行编号校准,通过底座41上的固定螺丝12安装不同分段的外筒43,固定螺丝12围绕底座41中心呈角度分布;(3) Use a crane to place the outer cylinder 43 on the wire groove 14 corresponding to the base 41, perform serial number calibration on the fixing screw 12 on the base 41 and the screw 46 holes on the bottom guard ring 44, and pass the fixing screw on the base 41 12 install the outer cylinder 43 of different segments, and the fixing screws 12 are angularly distributed around the center of the base 41;
(4)检查内筒42与外筒43的位置,要求位置准确,连接牢固,不易松动,否则易造成内、外筒43错位,无法保证咬合桩试样桩径和咬合量的大小;(4) Check the positions of the inner cylinder 42 and the outer cylinder 43. It is required that the position is accurate, the connection is firm, and it is not easy to loosen. Otherwise, the inner and outer cylinders 43 are easily misaligned, and the pile diameter and occlusal amount of the occlusal pile sample cannot be guaranteed;
(5)护环44的每一处接缝45均采用两颗螺丝46与一块刚性垫片47进行连接,外筒43的拼接线32与护环44的接缝45均采用密封胶进行密封,防止浇筑混凝土过程中发生漏浆现象。根据需要,拼接线32(或接缝45)的位置可以每隔几块厚壁弧形钢板设置一处。外筒43的内壁需涂上脱模剂,便于后期脱模;(5) Each seam 45 of the retaining ring 44 is connected with two screws 46 and a rigid gasket 47, and the splicing line 32 of the outer cylinder 43 and the seam 45 of the retaining ring 44 are all sealed with a sealant. Prevent grout leakage during pouring of concrete. According to needs, the position of splicing line 32 (or seam 45) can be set every few thick-walled curved steel plates. The inner wall of the outer cylinder 43 needs to be coated with a release agent to facilitate later demoulding;
(6)将所有已涂刷脱模剂的钢管51置入咬合桩模具内,对任一相邻的两根素桩进行混凝土的浇筑。当混凝土从开始浇筑至1/3~2/3桩长时,全部使用振动台进行振捣;当混凝土继续浇筑至设计的桩长时,停止振动台工作,采用手提式震动棒进行低频振捣,防止出现密封胶开裂、混凝土跑浆现象;(6) Put all the steel pipes 51 coated with release agent into the occlusal pile mold, and pour concrete on any two adjacent plain piles. When the concrete is poured from the beginning to 1/3 to 2/3 of the pile length, all the vibrating table is used for vibration; when the concrete continues to be poured to the designed pile length, the vibrating table is stopped and the portable vibrating rod is used for low-frequency vibration , to prevent sealant cracking and concrete slurry phenomenon;
(7)在这两根素桩之间的钢管51内下放钢筋笼,并浇筑、振捣。在混凝土初凝前,利用吊车拔出所述钢管51,并通过采用手提式震动棒进行低频振捣,使荤桩、素桩充分咬合;(7) Put down the reinforcement cage in the steel pipe 51 between these two plain piles, and pour and vibrate. Before the initial setting of the concrete, use a crane to pull out the steel pipe 51, and carry out low-frequency vibration by using a portable vibrating rod, so that the meat pile and the plain pile are fully occluded;
(8)重复上述步骤(6)和(7),直至所有荤桩、素桩浇筑完成。受制样时间和室内环境的约束,在混凝土搅拌时应适当添加混凝土缓凝剂;(8) Repeat the above steps (6) and (7) until all the meat piles and plain piles are poured. Constrained by sample preparation time and indoor environment, concrete retarder should be added properly when mixing concrete;
(9)将整套咬合桩装置吊运至推车上,送至混凝土标准养护室,48h后拆模,先拆外筒43,再拆内筒42。若内筒42较难拆模时,可用吊车将其与咬合桩试样一起调离地面10cm,试样下方一定面积内铺设5cm左右厚度的中砂,再用大号橡胶锤等工具敲击咬合桩试样顶部,使其脱离内筒42,该过程必须有专人监督,防止出现意外;(9) Hoist the whole set of occlusal pile device onto the cart, and send it to the concrete standard curing room. After 48 hours, the formwork is removed, and the outer cylinder 43 is removed first, and then the inner cylinder 42 is removed. If the inner cylinder 42 is difficult to remove the formwork, it can be moved 10cm away from the ground together with the occlusal pile sample by a crane, and medium sand with a thickness of about 5cm is laid in a certain area under the sample, and then the occlusion is struck with a large rubber hammer and other tools Pile the top of the sample so that it is separated from the inner cylinder 42. This process must be supervised by a special person to prevent accidents;
(10)将咬合桩试样在标准条件下继续养护至28天,即可得到完整的咬合桩模型试样。(10) Continue curing the occlusal pile sample under standard conditions for 28 days to obtain a complete occlusal pile model sample.
