以下结合附图对本实用新型做进一步的说明： Below in conjunction with accompanying drawing, the utility model is further described:
如附图1所示，本实用新型的刚柔复合型支护止水RCP桩，其结构主要包括：搅拌桩1，刚性长方形芯桩2，交集咬合部3，支护止水闭合连续墙4，降坡基坑5，刚性工字形段芯桩8。本实用新型的刚柔复合型支护止水RCP桩位于深基坑外侧6与深基坑内侧及底板7之间。 As shown in Figure 1, the structure of the rigid-flexible composite support water-stop RCP pile of the present invention mainly includes: a stirring pile 1, a rigid rectangular core pile 2, an intersection joint 3, and a support water-stop closed continuous wall 4 , descending slope foundation pit 5, rigid I-shaped section core pile 8. The rigid-flexible composite support water-stop RCP pile of the utility model is located between the outer side 6 of the deep foundation pit, the inner side of the deep foundation pit and the bottom plate 7 .
本实用新型的刚柔复合型支护止水RCP桩，主要适用于建筑物基础深基坑的支护与止水。 The rigid-flexible composite supporting water-stopping RCP pile of the utility model is mainly suitable for supporting and water-stopping deep foundation pits of building foundations.
如图1和图2所示，在用于深基坑支护时本实用新型的技术特征是：在降坡基坑5的范围内，利用大直径水泥土搅拌桩1成桩后，及时地插入截面呈长方形状的钢筋混凝土预制刚性芯桩2,插入安装时，按长边方向与基坑支护墙体4的轴线垂直，以增大基坑支护的水平受力(见图1)，深基坑内侧及底板7的坑内土移除后，起到深基坑支护，抵抗深基坑外侧6坑壁土压力的作用。刚柔复合型支护止水RCP桩在深基坑的四周采用成排连续的方法施工，因其两桩之间的中心间距均小于1倍桩直径，可形成搅拌桩柔性桩体的交集咬合部3。如图1b所示，桩体的连续施工可形成支护止水闭合连续墙4，达到深基坑支护与止水的双重功能，从而提高工效和降低成本。 As shown in Figures 1 and 2, when used for deep foundation pit support, the technical characteristics of the utility model are: within the scope of the descending slope foundation pit 5, after the large-diameter cement-soil mixing pile 1 is piled, the Insert the reinforced concrete prefabricated rigid core pile 2 with a rectangular cross-section. When inserting and installing, it is perpendicular to the axis of the foundation pit support wall 4 according to the long side direction, so as to increase the horizontal force of the foundation pit support (see Figure 1) , after the inner side of the deep foundation pit and the soil in the bottom plate 7 are removed, it plays the role of supporting the deep foundation pit and resisting the soil pressure on the wall 6 outside the deep foundation pit. Rigid-flexible composite support and water-stopping RCP piles are constructed in rows and continuously around the deep foundation pit, because the center distance between the two piles is less than 1 times the pile diameter, which can form the intersection and bite of the flexible pile body of the mixing pile Part 3. As shown in Figure 1b, the continuous construction of the pile body can form a closed diaphragm wall 4 for supporting and sealing water, achieving the dual functions of deep foundation pit support and water sealing, thereby improving work efficiency and reducing costs.
如附图1所示，刚柔复合型支护止水RCP桩的单桩结构是由先施工的大直径水泥土搅拌桩1，之后在刚刚完成的搅拌桩中心位置，通过微振动或静压方法插入刚性芯桩2组合而成的。刚性芯桩2主要由：刚性桩体2a，钢筋主筋2b，箍筋2c组成。刚性芯桩的几何形状可以是长方形(见图3)或工字形(见图4)，根据不同几何形状芯桩按抗弯能力最大并与深基坑支护连续墙体4垂直的方向进行安装。刚性芯桩起基坑支护的作用，而水泥土搅拌桩是低强度柔性桩体，起稳固刚性芯桩的作用，在插入刚性芯桩过程中产生的微振动，使芯桩与水泥土搅拌桩具有良好的亲和握裹性，组合成刚柔复合型支护止水RCP桩。 As shown in Figure 1, the single pile structure of the rigid-flexible composite support water-stop RCP pile is a large-diameter cement-soil mixing pile 1 constructed first, and then at the center of the just completed mixing pile, through micro-vibration or static pressure The method is formed by inserting 2 rigid core piles. The rigid core pile 2 is mainly composed of: a rigid pile body 2a, a main reinforcing bar 2b, and a stirrup 2c. The geometric shape of the rigid core pile can be rectangular (see Figure 3) or I-shaped (see Figure 4), and according to different geometric shapes, the core pile should be installed in the direction that has the largest bending resistance and is perpendicular to the continuous wall 4 of the deep foundation pit support . The rigid core pile plays the role of foundation pit support, while the cement-soil mixing pile is a low-strength flexible pile body, which plays the role of stabilizing the rigid core pile. The micro-vibration generated during the insertion of the rigid core pile causes the core pile to mix with the cement-soil The piles have good affinity and grip, and are combined into rigid-flexible composite support and water-stop RCP piles.
刚柔复合型支护止水RCP桩在深基坑应用时，桩体为悬臂支护坑壁结构(见图1和图2)，受力特点为悬臂梁(柱)形式抵抗坑壁 土压力，桩体中的刚性芯桩起到悬臂梁的作用。刚柔复合型支护止水RCP桩在深基坑的四周采用成排连续的方法施工，因其两桩之间的中心间距均小于1倍桩直径，可形成搅拌桩柔性桩体的交集咬合区3,形成连续支护止水闭合连续墙4，起到深基坑止水的作用。 When the rigid-flexible compound support water-stop RCP pile is applied in a deep foundation pit, the pile body is a cantilever support pit wall structure (see Figure 1 and Figure 2), and the force characteristic is that the cantilever beam (column) resists the pit wall soil pressure , the rigid core pile in the pile body acts as a cantilever beam. Rigid-flexible composite support and water-stopping RCP piles are constructed in rows and continuously around the deep foundation pit, because the center distance between the two piles is less than 1 times the pile diameter, which can form the intersection and bite of the flexible pile body of the mixing pile In zone 3, a closed diaphragm wall 4 with continuous support and water-stop is formed to play the role of water-stop for deep foundation pits.
