Problems solved by technology

[0005] In order to solve the problem of low utilization rate of existing construction waste and severe water seepage caused by high porosity of embankments under sandy soil conditions, the present invention provides a construction waste reinforced river embankment under sandy soil conditions. The embankment sets up a special modified waterproof layer between the facing surface of the embankment and the cement concrete layer, and uses different grades of construction waste, quicklime, cement, etc. to reform, and can gradually combine and solidify with the water seeping through the cement concrete layer. Prevent seepage from penetrating deep into the dam body, thereby destroying the strength of the dam body, causing hidden dangers, and improving the utilization rate of construction waste, so that waste resources can be reused

Embodiment 1

[0053] like figure 1 with 2 As shown, the construction waste in the shequo, including the river embankment, including the river embeid of the sand, and the cement concrete layer 2 poured onto its surface, in the cement concrete layer 2 welcomes surface and There is a modified waterproof layer 3 between the river embankment, the modified waterproof layer 3 is a fine particle construction waste and a particle size of 15-30 mm from a fine particle construction waste and a particle diameter of 10 mm. Particle construction garbage is compared to the mass of 1.5: 1: 3.5: 2.5: 1.5.

[0054] In the present embodiment, the thickness of the modified waterproof layer 3 is generally 20-50 cm, which is freely selected according to the actual situation.

[0055] The above is the basic embodiment of the present invention, and further improvement, optimization, and defined on the above basis, thereby obtaining the following examples:

Embodiment 2

[0057] This embodiment is an improvement scheme according to the first embodiment, and the main structure is the same as in Example 1, and the improvement point is: figure 1 with 2 As shown, the modified waterproof layer 3 is disposed between the river embankment 4, and the geotextile 4 generally uses at least two layers, preferably waterproof material.

Embodiment 3

[0059] In this example, another improvement scheme is made based on the first embodiment, and its main structure is the same as in Example 1, and the improvement point is: figure 1 with 2 As shown, the modified waterproof layer 3 is distributed along the river bank extension, and the top of the seepage column 5 extends to the concrete sealing box 6 provided in the top of the river bank, filled in the concrete seal 6 Cement and moisture loess are mixed with a mixture of 4: 1.

[0060] The construction method of the seepage column 5 is:

[0061] 1) Select the PC tube having a diameter of 2 mm through the surface of the surface, and the PC tube is placed in advance when the construction expansion soil modified waterproof layer 3 is used, and the top of the PC tube is protected from the top surface of the river embankment. And when the cement concrete layer is poured, the top of the PC is exposed to the top of the river embankment;

[0062] 2) Inject the mortar into the PC tube, and t...

Abstract

A river embankment reinforced by construction waste under sandy soil, comprising a river embankment body rammed with sand and a cement concrete layer poured on its surface, with a A modified waterproof layer, the modified waterproof layer is made of collapsible loess, quicklime, cement, fine particle construction waste with a particle size of no more than 10mm, and medium particle construction waste with a particle size of 15-30mm according to the ratio of 1.5:1:3.5 The mass ratio of :2.5:1.5 is mixed and rammed. In the present invention, a special modified waterproof layer is set between the facing surface of the embankment and the cement concrete layer, and construction waste, quicklime, cement, etc. of different grades are used for transformation, and it can be combined and solidified gradually with the water seeping through the cement concrete layer , to prevent seepage from penetrating deep into the dam body, thereby destroying the strength of the dam body, causing hidden dangers, and improving the utilization rate of construction waste, so that waste resources can be reused.

Description

Technical field [0001] The present invention further relates to the field of construction waste solid waste, construction waste is specifically enhanced the embankments Sandy Soil Geology. Background technique [0002] Southern Jiangxi is a multi-multi-water river area, in order to prevent the erosion of the river banks of the destruction of the natural form, is generally used cement concrete dam on the river embankment reinforcement; [0003] When the river embankment reinforcement of concrete, its general operation is to use lots which itself is based on geological conditions, ramming forming embankment body with soil embankment body ramming the environment in general is much more than the original river bank to prevent flood water overflowing increase embankment, after pouring concrete as reinforcing and waterproofing a surface thereof; sand but in the geological conditions, since the larger particles of the sand layer, the lack of cement to each other, and permeability coeffi...
