Dividing wall anchoring type supporting structure and construction method thereof

Abstract

The invention discloses a dividing wall anchoring type supporting structure and a construction method thereof. The supporting structure is used for supporting a fill slope body and comprises a cast-in-place anchor plate, anchor rods and a counterfort type retaining wall, the counterfort type retaining wall comprises a bottom plate, soil retaining vertical plates and a plurality of counterforts arranged in parallel, and the bottoms of the counterforts and the bottoms of the vertical plates are vertically poured on the bottom plate; one side face of each counterfort is tightly attached to one side face of the corresponding vertical plate, and the space between every two adjacent counterforts is filled with the fill slope body; and the cast-in-place anchor plate is arranged in the fill slopebody, the cast-in-place anchor plate is connected with one ends of the anchor rods, and the other ends of the anchor rod pass through the space between two adjacent counterforts, penetrate through thevertical plates and then are limited on the sides, away from the counterforts, of the vertical plates. The structure form is simple, stress is reasonable, practicability is high, the construction process is simple and convenient, cost is low, the stability of the fill slope is high, higher engineering practical value and important social and economic benefits are achieved, and the structure is worthy of large-scale application and popularization.

Description

technical field [0001] The invention belongs to the technical field of geotechnical support engineering, and in particular relates to a partition anchored support structure and a construction method thereof. Background technique [0002] In recent years, the contradiction between more and more land for mountain reclamation, urbanization and the reduction of buildable land is particularly prominent. A large number of roads, railways, airports, and residences are built in the western mountainous areas, resulting in a large number of excavation and filling works to form construction land. As we all know, for the characteristics of filling engineering, because the soil used in the project is not the original soil, the stability of the filling soil is particularly prominent. In recent years, an endless stream of engineering accidents has caused huge threats to people's lives and property safety, and the economic losses to the society are even more immeasurable. It can be seen t...

Problems solved by technology

Although it can better solve the problem of filling slope support, due to its specific construction method and scope of application, these structures cannot be widely used

As far as the piles are concerned, increasing the pile diameter and pile length can provide a large support resistance and improve the safety and reliability of the support structure. As far as the gravity retaining wall is concerned, due to simple raw materials, convenient construction and low cost, it is suitable for lower slope support, but it cannot meet the support requirements for high slopes

However, such as reinforced soil retaining walls and other supporting mechanisms, due to the material and service life of the reinforced body, etc., the scope of use is limited.

At the same time, the anchor plate structure mainly uses the lateral resistance at the contact position between the soil and the anchor plate to provide the bearing capacity of the support structure. cracks, so that external rainwater seeps through and accelerates structural damage. In addition, due to the high construction requirements for placing anchor plates, it affects the effect of mechanical compaction and construction efficiency

Supporting structures like this cannot give full play to the performance of their supporting structures due to many limiting factors such as economic cost, construction procedures, construction materials, and scope of application.

[0004] Obviously, the existing support technology can no longer meet the development of filling engineering, especially the application of high filling engineering
