Drainage pipeline foundation in soft soil foundation and construction method of drainage pipeline foundation

Abstract

The invention relates to a drainage pipeline foundation in a soft soil foundation. The drainage pipeline foundation comprises a base and pull rods, wherein the base is placed in an excavated trench; a plurality of connecting rods are arranged at the side part of the base; the connecting rods are connected with head ends of the pull rods; and the tail ends of the pull rods are inserted into undisturbed soil on the two sides of the trench. The invention further discloses a construction method of the drainage pipeline foundation in the soft soil foundation. The construction method comprises the steps of after trench excavation, inserting the pull rods into reserved positions of the undisturbed soil on the two sides of the trench in advance, and standardizing the height; placing the base in the trench; connecting the connecting rods at the side part of the base with the pull rods for fixation through connecting nuts; grouting the undisturbed soil on the two sides of the trench; and mounting a drainage pipeline, and carrying out trench backfilling according to the requirement to enable the pull rods, the base and the surrounding soil to form a stable and flexible integral body. The drainage pipeline foundation is particularly applicable to the soft soil foundation and can be directly mounted on site, the pile foundation treatment time is saved, the construction is convenient and safe, and the construction period is short.

Description

technical field [0001] The invention relates to a drainage pipe foundation in soft soil foundation and a construction method thereof, belonging to the technical field of municipal facilities. Background technique [0002] Piping foundations are an essential part of the plumbing installation process. At present, the pipeline foundations used in engineering are generally divided into two types: one is concrete foundation, which is to lay a certain thickness of plain concrete or crushed stone cushion at the bottom of the pipe trench that meets the design bearing capacity requirements, and the cushion strength meets the installation requirements Finally, steel bars are bound on the cushion, formwork is installed, and cement concrete is poured to make a flat foundation. The precast concrete flat foundation needs to be cured, and then the formwork is removed, and drainage pipes are installed; Lay a certain thickness of natural graded sandstone or medium-coarse sand at the bottom ...

AI Technical Summary

Problems solved by technology

Now the general method is to add flexible piles such as sand piles and gravel piles to strengthen the bearing capacity of the foundation. Different from the bearing capacity of the foundation of the surrounding untreated road sections, it is easy to induce uneven settlement during the later use of the road, resulting in cracking of the road surface

[0005] There are still inconveniences and defects in the use of the above-mentioned drainage pipeline foundation, which needs to be further improved urgently
