Problems solved by technology

[0004] 1. After the foundation is processed by mechanical rolling, the strength can meet the requirements in a short time, but after a period of time, the foundation may sink and the bearing capacity is not enough;
[0005] 2. Pollution of the environment;
[0006] 3. The construction process is complicated, and the on-site construction organization is complicated, and accidents are easily induced during the construction period
It overcomes the existing complicated process, environmental pollution, insufficient backfill compactness, and uneven foundation settlement, which induce pipeline damage and water leakage

Embodiment Construction

[0034] The technical solutions and specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0035] A construction method of pavement structure based on water shaking sand backfilling technology, comprising the following steps:

[0036] 1) According to the situation of the project site, after grooving, select the appropriate spacing for use in sections, the spacing is generally about 50m, mainly considering the on-site traffic, construction period, and the utilization of circulating water in the water-shaking process, and make appropriate adjustments according to the site;

[0037] 2) After the groove reaches the design depth, first check whether the bearing capacity of the bottom of the groove meets the requirements, generally reaching 100KP. If it does not meet the requirements, it is necessary to replace the pipe foundation to ensure the bearing capacity of the pipe foundation.

[0038] 3) Check whether the ...

Abstract

The invention discloses a pavement structure based on the water sand backfilling technology and a construction method thereof. The thickness of the pavement structure is 50cm. The pavement is divided into a surface layer, a base layer and a cushion layer from top to bottom, wherein the thickness of the surface layer is in a range of 8cm to 10cm, the thickness of the base layer is in a range of 18cm to 22cm, and the thicknesses of the cushion layer are in a range of 18cm to 22cm. the cushion layer is arranged between a soil layer and the base layer, and backfilling sand is arranged under the cushion layer. The process is simple and practical, and bearing capacity strength and stability of backfilling soil are guaranteed to be in accordance with engineering safety requirements.

Description

technical field [0001] The invention belongs to the field of municipal engineering, and relates to a pavement structure and a construction method based on water shaking sand backfilling technology. Background technique [0002] With the progress of society and the development of cities, more and more municipal pipeline projects are being constructed. After some pipelines are slotted and installed, they need to be backfilled immediately and municipal traffic should be restored as soon as possible. [0003] The problems existing in the prior art are: [0004] 1. After the mechanically rolled foundation is treated, the strength can meet the requirements in a short time, but after a period of time, the foundation may sink and the bearing capacity is not enough; [0005] 2. Pollution of the environment; [0006] 3. The construction process is complex, the site construction organization is complicated, and accidents are easily induced during construction. [0007] In order to e...
