Problems solved by technology

[0003] Due to its good reinforcement and protection effect, the obliquely inserted pile-slab wall is the development direction of the pile-slab wall technology. The positioning technology of the obliquely inserted pile-slab wall is an important part of the oblique-inserted pile-slab wall. The previous pile-slab wall was not accurately positioned. Low efficiency and low connection reliability are the important factors that make it difficult to promote the inclined-inserted pile-slab wall, creating conditions for the promotion of the inclined-inserted pile-slab wall. At present, an accurate, efficient, and low-cost positioning method is urgently needed

Embodiment 1

[0060] This embodiment is based on the positioning method of the inclined inserting plate based on the excavation condition of the anti-slide pile, including the following steps:

[0061] (1) Production of model boards

[0062] Such as figure 1 As shown, make the same model board 6 with the cross-section size of the inclined board, the model board cross-section includes a pentagon with three right-angled sides, includes three rows of positioning holes 7, and the distance between each row is the same and each row of holes is the same as The distances between the holes are the same, including the first obtuse angle 1 , the second obtuse angle 2 , the first right angle 3 , the second right angle 4 and the third right angle 5 .

[0063] Choose a 10mm thick wooden board to make a model board with the same cross-sectional size as the inclined board. The model board only determines the position of the reinforcement on the retaining wall and is not poured in the anti-sliding pile. Th...

Embodiment 2

[0105] Using the method of Example 1, the anti-sliding piles on the Dongchuan-Gele Expressway in Kunming City were positioned with inclined inserting plates.

[0106] Take the positioning of the oblique insertion plate of the 1#-2# anti-slide pile on the left pile wall of K32+860~+930 as an example.

[0107] The top design of the anti-slide piles is cut-off after excavation, and the inclination angle of the slanted inserts is designed to be 45°. The basic information of the anti-slide piles and slanted inserts is shown in Table 4. According to the horizontal positioning formula in Example 1, the distance L between the five positioning points of the model plate and the side slope of the anti-slide pile is calculated. j , see Table 1 for Type A plate, see Table 2 for Type B plate,

Abstract

The invention relates to an inclined insert plate positioning method based on an excavation working condition of an anti-slide pile, and belongs to the field of slope engineering. The method comprises the steps that (1) a mould plate is manufactured; (2) height computation of the mould plate is carried out; (3) the horizontal position of the mould plate is calculated; (4) the mould plate is positioned; and (5) inclined insert plates are positioned. According to the method, the mould plate is positioned in the slide-resistant pile, overall positioning replaces previous single-root positioning, and the technology and construction are convenient and rapid; the positioning is accurate, and in addition, the collision between stirrups and bearing rods inside the slide-resistant pile can be avoided; and dismantling of dadoes outside the inclined insert plates on the two sides of the slide-resistant pile can be reduced from the whole project, the two ends of the inclined insert plates are fixed in the dadoes in an embedded mode, and therefore the overall safety can be improved, and steel bars at the joints can be prevented from being rusted. Compared with other positioning modes, the method has the advantage that the mould plate can be repeatedly used and therefore the investment can be saved.

Description

technical field [0001] The invention relates to a positioning method for an inclined insertion plate, in particular to a positioning method for an inclined insertion plate based on the excavation condition of an anti-slide pile, and belongs to the field of all slope engineering. Background technique [0002] At present, pile-slab walls are widely used in slope retaining protection. Inclined pile-slab walls are a new technology developed on the basis of ordinary pile-slab walls. With the construction of beautiful China and green passages and the construction of beautiful Yunnan strategies The implementation of green reinforcement and protection of slopes has attracted more and more attention. The use of green reinforcement and protection of slopes to partially or completely replace the existing pure concrete or mortar masonry structures will be the trend of slope reinforcement and protection in the future. The obliquely inserted pile-slab wall technology has been widely used ...
