Embodiment Construction

[0031] The present invention will be further described below through specific examples, but the present invention is not limited by the following examples.

[0032] Pile of the present invention adds the concrete construction step of anchor foundation pit support method embodiment 1 as follows:

[0033] 1. According to the pile position plan, after the pile position is staked out, the construction of the cement mixing pile 1 is carried out first, as shown in Figure 4, to form a water-stop curtain, and then the construction of the bored pile 2 is carried out, as shown in Figure 5, to form Retaining wall for slope protection and retaining soil.

[0034] 2. Excavate to the level 3 of the top beam bottom, as shown in Figure 6.

[0035] 3. Drill the bored pile 2 to the design elevation, as shown in Figure 7.

[0036] 4. The first row of anchor rods 4a is constructed in the soil layer between adjacent bored piles 2, and the anchor rods are prestressed, as shown in Fig. 1 , Fig. 2 ...

Abstract

The invention discloses a foundation pit support method with pile and anchor, belonging to an external staying support technique field of the supporting structural retaining of the foundation pit, comprising that: a. bored piles are constructed to form a retaining wall, after lofting of the pile location according to the planar graph of the pile location; b. the soil is excavated to the bottom elevation of the top beam; c. the bored piles are chiseled to the design elevation; d. the first row of anchors are constructed in the soil layer between the adjacent bored piles; e. the top beams are constructed; f. the soil is excavated to the constructing position of the second row of anchors; g. the second row of anchors are constructed; h. the processes of f and g can be repeated until to the last row of anchors, according to different design conditions; i. the soil is excavated to the bottom of the foundation pit. The foundation pit support method with pile and anchor has the advantages of avoiding a lot of inner supports, providing an open working face for soil excavation, creating a good condition for mechanized construction, increasing the construction progress, needing not to treat the water stop of supporting, bracing substitution, dismantling support during the subsequent construction of the basement, convenient construction, increasing the progress, reducing the construction cost.

Description

technical field [0001] The invention discloses a foundation pit support method with piles and anchors, and belongs to the technical field of building foundation pit support engineering construction. Background technique [0002] There are many kinds of existing building foundation pit support systems, each of which has its own advantages and different scopes of application. Among them, the pile support system is more commonly used, but it contains a large number of internal supports, which is not convenient for excavation and structural construction, which affects the construction progress, and also brings a lot of inconvenience to the subsequent construction, affecting the construction progress. Contents of the invention [0003] In order to overcome the above-mentioned disadvantages, the present invention provides a pile-and-anchor foundation pit support method that can shorten the construction period, speed up the construction progress, and reduce the cost. [0004] In...
