Positioning device for inclined steel pipe support slope and construction method
The invention discloses a positioning device of an inclined steel pipe support slope. The positioning device comprises a guide hole device body, fixed seats, a supporting piece and a reinforcing assembly, the reinforcing assembly comprises a fastening piece and a reinforcing beam, the fastening piece is a common anchor rod or a grouting anchor rod, the reinforcing beam is a long-strip-shaped plate-shaped body component, the whole guide hole device body is of a wedge-shaped structure, a plurality of fixed seats are arranged at the bottom of the hole guiding device body, a guide hole is further formed in the middle of the guide hole device body. According to the positioning device of the inclined steel pipe support slope, a steel sheet pile driver is adopted to obliquely insert the supporting piece into a soil body according to the slope of a slope, then slope excavation is carried out on a slope body with a steep dip angle, slope protection is carried out on the slope body with the steep dip angle through the supporting piece, and therefore the supporting effect is achieved; and meanwhile, by combining the stability of the slope body and the excavation depth of a foundation pit, the anchor rod and the supporting piece can be additionally arranged at proper positions for combined supporting, and therefore high-stability slope protection is achieved, and the problems for a shallow foundation pit, a land red line is close, undisturbed soil sloping cannot be met, the sloping dip angle is extremely steep, and pile-in-row and pile-anchor supporting cost is high can be solved.
本发明公开一种斜向钢管支护边坡的定位装置，它包括引孔装置本体、固定座和支撑件以及加固组件，加固组件包括紧固件和加固梁，紧固件为普通锚杆或是注浆锚杆；所述加固梁为长条状的板状体构件；引孔装置本体整体呈楔形结构，在引孔装置本体的底部设有数个固定座；在引孔装置本体的中部还设有引孔。本发明采用钢板桩打桩机将支撑件按放坡的坡度斜向插入土体，然后对陡倾角的坡体进行放坡开挖，通过支撑件对陡倾角坡体进行护坡，达到支护效果；同时结合坡体稳定性及基坑开挖深度，可在适当位置增加锚杆与支撑件联合支护，达到高稳定性护坡，可解决浅基坑，用地红线近较近，无法满足原状土放坡，放坡倾角极陡，排桩、桩锚支护费用高等难题。
