Embodiment Construction

[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with the embodiments.

[0030] Such as Figure 1 to Figure 6 Shown, a kind of municipal subgrade construction method of the present invention, the method comprises the following steps:

[0031] S1: Cultivate a 400-500mm high soil ridge on the edge of the land acquisition line first to block the external surface water, and dig a temporary drainage ditch inside the soil ridge to drain the surface water, and remove trees, weeds and garbage around the roadbed, Trees and shrubs that affect traffic shall be felled and transplanted after consultation with relevant departments;

[0032] S2: Treat the base of the subgrade again. For local foundations whose bearing capacity does not meet the design requirements, and for cases where the foundation is soft and elastic due to water in s...

Abstract

The invention belongs to the technical field of roadbed construction, and specifically relates to a municipal roadbed construction method. The breaking hammer used in the construction method includes a body and a drill rod; the body end is symmetrically provided with connecting rods; each of the connecting rods Two No. 1 rods are symmetrically hinged on the upper side, and the lower end of the No. 1 rod is connected with a protective cover; the cut surface of the protective cover is in the shape of a circular platform. When the breaker is not in use, the lower end of the protective cover is flush with the lower end of the drill rod; By installing a protective cover on the breaker, when the drill rod breaks the road surface, the gravel can directly splash into the protective cover. Breaking noise, reducing the harm of noise to construction personnel on site and the disturbance to the lives of surrounding residents.

Description

technical field [0001] The invention belongs to the technical field of roadbed construction, in particular to a municipal roadbed construction method. Background technique [0002] Municipal engineering refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings and structures that are set up within the planning and construction scope of urban areas, towns and villages, and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. And equipment, various public infrastructure constructions supporting urban life belong to the category of municipal engineering, common urban roads, bridges, subways, various pipelines closely related to life: rainwater, sewage, upper water, reclaimed water, and parts other than the red line of electricity , Telecommunications, heating, gas, and squares, urban greening construction, all belong to the category of municipal engineering...
