Problems solved by technology

[0005] The purpose of the present invention is to provide a vibrating watertight backfilling method for pipe trenches in foundation pits. On the one hand, it can save a large amount of construction waste removal and treatment costs; Compared with stone powder, medium coarse sand, etc., the material cost can be reduced by more than 50%. It aims to solve the construction technology of layered filling and layered compaction in the prior art. The layer thickness of this method should not be too large, which will cause construction efficiency. Low, and it is often difficult to meet the requirements of the code and design for the degree of compaction, making it prone to problems of settlement and hollowing in the later stage

Embodiment 1

[0034] refer to Figure 1-2 , the vibrating watertight backfilling method of the pipe ditch of the foundation pit, which specifically includes the following steps:

[0035] S1: In the production stage of recycled materials, firstly, the construction waste is pretreated and sorted, and the wood, plastic, steel bars and domestic waste in the construction waste are removed through manual sorting;

[0036] S2: use the mobile crusher to crush the construction waste sorted in S1, so that the particle size of the crushed construction waste material is 1-10mm;

[0037] S3: Precisely sort the construction waste materials in S2, and remove iron filings and mud impurities in the materials by means of magnet adsorption and water washing;

[0038] S4: The material is further screened by controlling the size of the screen, used to prepare recycled aggregates of different specifications, and placed aside for use;

[0039] S5: In the backfilling stage of recycled materials, first connect th...

Abstract

The invention relates to the technical field of foundation pit pipe ditch backfilling, and discloses a vibrating watertight backfilling method of foundation pit pipe ditches. The vibrating watertightbackfilling method comprises the following steps that S1, in the reclaimed material production stage, pre-treatment sorting on construction waste is firstly carried out, and wood, plastic, rebar and domestic waste in the construction waste are removed through by manual sorting; S2, a mobile crusher is used for crushing the construction waste obtained after sorting in the step S1, so that the particle size of a broken construction waste material is 1 mm-30 mm; S3, accurate sorting is carried out on the construction waste material in the step S2, and scrap iron and mud impurities in the materialare removed by a magnet adsorption and washing mixed manner; and S4, the screen size is controlled to further screen and treat the material, the material is used for preparing recycled aggregates indifferent specifications, and the recycled aggregates are put aside for standby application. According to the vibrating watertight backfilling method, comprehensive utilization of the building waste recycling material is carried out, the processing pressure of the construction waste generated by urban renewal can be alleviated, and the land space of the building and construction waste receiving site is saved.

Description

technical field [0001] The patent of the present invention relates to the technical field of backfilling pipe trenches in foundation pits, in particular, to a vibration watertight backfilling method for pipe trenches in foundation pits. Background technique [0002] With the development of society, various new buildings emerge in an endless stream. However, before the new buildings are built, the old buildings on the ground need to be demolished. Therefore, construction waste emerges as the times require. In 2016, Shenzhen Luohu sheds were transformed into people's livelihood. Taking the project as an example, the demolition of the buildings in the second-line flower arrangement field produced 2 million tons of construction waste. However, the existing technology can only be used to transport and fill pits for construction waste, which not only occupies land resources, but also produces environmental pollution. This resource is processed and utilized. [0003] With the simu...
