Problems solved by technology

However, the current method of using drainage boards to strengthen weak foundations uses a large number of total drainage boards, which has a long construction period and high cost. Moreover, the verticality deviation of the drainage boards is relatively large, and the drainage boards are prone to loosening, resulting in poor drainage effect of the drainage boards. The effect of weak foundation reinforcement is average

Embodiment Construction

[0026] Scope of application of the present invention: it is suitable for soft foundations such as silt, muddy soil, silt and saturated soil.

[0027] Such as Figure 1 to Figure 3 As shown, a weak foundation drainage board reinforcement method includes the following steps:

[0028] (a) Site cleaning: Responsible for cleaning tree roots, weeds, garbage, waste residue and obstacles specified by the supervisor in the construction area. The vegetation clearing on the surface of the construction site of the main project shall be extended to a distance of 3m from the maximum excavation line shown in the construction drawing or the outside of the building foundation line. Then, the on-site cleaning wastes are sorted and treated, and the specific classification is as follows: the cleared items are valuable materials, which should be transported to the designated place for storage and storage; the cleared items are worthless combustibles, which should be burned as soon as possible. N...

Abstract

The invention discloses a strengthening method for soft foundation drain boards. The method comprises the following steps that (a) a site is cleaned; (b) a water filtering layer is laid; (c) a drain board zone is arranged; (d) the drain boards are arranged in an inserted mode; (e) the drain boards are strengthened; (f) the drain board construction detection is conducted; and (g) the ends of the drain boards are treated. The total number of the drain boards arranged in strengthening construction is reduced, the construction period is shortened, the cost is reduced, the perpendicularity deviation of the inserted drain boards is low, and the supporting and strengthening effect of the drain boards is obvious, so that the drainage effect of the drain boards is obvious, consolidation of a soft foundation is accelerated, the bearing capacity of the soft foundation is improved, the soft foundation reaches the high consolidation degree in a short time, and foundation project sedimentation is obviously reduced.

Description

technical field [0001] The invention relates to the technical field of weak foundation reinforcement, in particular to a method for reinforcing a weak foundation drainage board. Background technique [0002] During the construction and use of buildings, foundations made of soft soils such as silty soil and miscellaneous fill are often encountered, and certain measures need to be taken to reinforce them to increase the bearing capacity. However, often due to poor or inadequate foundation reinforcement measures, quality problems in foundation engineering occur. [0003] At present, the use of drainage board reinforcement is a common method for shallow foundation reinforcement. Drainage board is an important material that is indispensable in the drainage system of construction projects. There are many classifications of drainage boards. Generally speaking, it can be divided into plastic drainage boards, storage drainage boards, coiled drainage boards, and anti-seepage drainage...
