Problems solved by technology

Due to the collapsibility of Malan loess, under the influence of certain external factors, especially rainwater, it is very easy to cause collapsibility, resulting in cracking of houses, causing considerable economic losses to house users and even posing a threat to personal safety.

Embodiment 1

[0052] The specific embodiment of the present invention is described below in conjunction with embodiment and comparative test, so that understand the concrete implementation of the present invention better, it should be noted that the scope of protection of the present invention is not limited to following examples.

[0053] A new method for foundation treatment of rural adobe houses in loess areas, including:

[0054] (1) The construction of leveling the site, the specific steps are:

[0055] (1a) Clean up the stagnant water in and around the site and remove the artificial garbage in the site.

[0056] (1b) The area higher than the construction site shall be manually removed by means of manual removal, and small excavators may be used for larger engineering volumes. For the area with a height difference of 96cm on the south side of the site, it is dug into a step shape, the height of the steps is 30cm, and the width of the upper and lower steps does not exceed 20cm.

Embodiment 2

[0079] A new method for foundation treatment of rural adobe houses in loess areas, including:

[0080] (1) The construction of leveling the site, the specific steps are:

[0081] (1a) Clean up the stagnant water in and around the site and remove the artificial garbage in the site.

[0082] (1b) The area higher than the construction site shall be manually removed by means of manual removal, and small excavators may be used for larger engineering volumes. For the area with a height difference of 96cm on the south side of the site, it is dug into steps, the height of the steps is 30cm, and the width of the upper and lower floors of the platform does not exceed 20cm.

[0083] (1c) Use black loess in other places as filler, each layer with a thickness of 25cm, tamp with a frog-type tamping machine, tamp each layer 3 to 4 times, sprinkle water on the surface after each layer is tamped, and use the soil layer The standard is no water accumulation on the surface. For this constructi...

Abstract

The invention discloses a foundation for rural adobe houses in loess areas and a processing method thereof. Step 1 of the method: level the site, clean up the accumulated water on the site, and set the drainage slope to 0.5% to 6%; step 2: lay out the foundation. ; Step 3: Excavate the new Holocene loess; Step 4: Clean the foundation trench; Step 5: Consolidate the lower black soil layer; Step 6: Lay a lime soil cushion on the compacted black soil layer; Step 7: Layer the lime soil A brick foundation is laid on the pad. This invention corrects the problem of collapsibility of the loess caused by digging out the black loam soil layer with water-proof properties in the foundation treatment of rural houses in loess areas and directly placing the foundation on the collapsible Malan loess. The physical properties of the soil layer can effectively avoid the collapsibility of foundations in loess areas. It has good applicability to loess areas, and has the advantages of simple construction, low cost, and easy promotion.

Description

technical field [0001] The invention belongs to the technical field of foundation treatment, and in particular relates to a foundation of an adobe house in a rural area in a loess area and a treatment method thereof. The invention is a new technology for preventing loess foundations from collapsing by using a black loess layer as a water-resisting layer. Background technique [0002] In the rural areas of Northwest my country, especially in Gansu and Ningxia, there are still many adobe houses, and most of these adobe houses will have different degrees of cracking or uneven settlement. According to the field investigation, it is found that this is directly related to the traditional way of handling the foundation of the houses of the local people. The soil layers in these areas are Holocene New Loess, Black Loess and Malan Loess from top to bottom, see figure 1 . Among them, black loam is mainly distributed in northern Shaanxi, eastern and central Longong, northern Shanxi a...
