CN102153255A - Method for treating constructed residual mud - Google Patents

Abstract

The invention discloses a method for treating constructed residual mud, which comprises the following steps of: (1) putting cement into the constructed residual mud and stirring the mud; (2) after the mud is settled, pumping clean water on the surface layer; and (3) conveying the mud residue to the outside and treating the mud residue. By putting the cement into the mud, stirring the mud uniformly, separating the clean water on the surface layer by cementation and settlement of the cement and soil, sand and broken stone granules in the mud and directly pumping and treating the clean water on the surface layer, the mud residue can be quickly and effectively discharged, so that the treatment formula quantity of the mud is reduced, the total treatment cost of the mud is reduced and the environment can be effectively prevented from being affected by the mud.

Description

A kind of method of handling construction residue mud

Technical field

The present invention relates to construction engineering technical field, particularly relate to the constructional method of handling construction residue mud.

Background technology

In underground diaphragm wall, filling pile construction process, need to use in a large number mud.Wherein, have the mud can recycle, unnecessary mud then must outward transport.At present, the mode of sealing vehicle outward transport is adopted in general mud outward transport, and there is following shortcoming in this method: its travelling speed is slower on the one hand, must drop into a large amount of equipment, and the cost that causes strengthens, and the duration is slow; Can occur the situation of mud outflow on the other hand in the transportation, influence environment.

Summary of the invention

For addressing the above problem, the invention provides a kind of method of clearing up that speed is fast, investment is low and not influencing the processing construction residue mud of environment.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of method of handling construction residue mud may further comprise the steps:

(1), in the remaining mud in construction back, throws in cement and stirring;

(2), etc. behind the mud sediment, pump drainage top layer clear water;

(3), remaining body refuse outward transport is handled.

As improvement of the technical scheme, step (1) is measured proportion, sand factor, the colloidity index of construction residue mud before earlier, calculates the ratio and the quantity of the cement of needs input according to These parameters.

With respect to prior art, beneficial effect of the present invention: cement is thrown in utilization of the present invention in mud, and after stirring, by the soil in cement and the mud, sand, the glued precipitation of gravel particle, isolate the top layer clear water, clear water direct pump drainage in top layer is handled, can fast and effeciently the entrucking of residue body refuse be transported, thereby reduce processing side's amount of mud, reduce the total processing cost of mud, and can prevent effectively that environment is subjected to the influence of mud.

Embodiment

A kind of method of handling construction residue mud of the present invention may further comprise the steps:

(1), in the remaining mud in construction back, throws in cement and stirring;

(2), etc. behind the mud sediment, pump drainage top layer clear water;

(3), remaining body refuse outward transport is handled.

Cement is thrown in utilization of the present invention in mud, and after stirring, by the soil in cement and the mud, sand, gravel particle bonding precipitation, isolate the top layer clear water, clear water direct pump drainage in top layer is handled, can fast and effeciently the entrucking of residue body refuse be transported, thereby the processing side that reduces mud is measured, reduce the total processing cost of mud, and can prevent effectively that environment is subjected to the influence of mud.

As preferred embodiment, measure proportion, sand factor, the colloidity index that construction remains mud before earlier in step (1), calculate the ratio and the quantity of the cement of needs input according to These parameters.Wherein, the calculating of cement injected volume and determine determining time of mud sediment, and sedimentary effect.

The cement consumption ratio of every side's mud calculates according to following experimental formula:

$C=\frac{120\mathrm{\κ}{\mathrm{\γ}}_1(1-\mathrm{\β})}{{\mathrm{\γ}}_2}$

Wherein:

γ ₂-remaining body refuse proportion (measuring after extracting the top layer clear water) is generally got

1.70～1.85, determine by thickness particulate physical properties in the mud, can basis

The practical situation in situ measurement.

γ ₁-mud balance.

κ-mud colloidity.

β-mud sand factor.

The cement quality (kg) that the pending mud of C-every cube is added.

It should be noted that in step (1), usage mining machine or miscellaneous equipment mix cement must be even, makes mud and cement mixing abundant.Mud (sand) amount that contains of tracing and monitoring top layer clear water prevents to stop up drainage pipeline behind the pump drainage when the clear water of step (2) pump drainage surface.

Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of spirit of the present invention, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.

Claims (2)

1. handle the method that construction remains mud for one kind, may further comprise the steps:

(1), in the remaining mud in construction back, throws in cement and stirring;

(2), etc. behind the mud sediment, pump drainage top layer clear water;

(3), remaining body refuse outward transport is handled.

2. processing construction according to claim 1 remains the method for mud, it is characterized in that: step (1) is measured proportion, sand factor, the colloidity index of construction residue mud before earlier, calculates the ratio and the quantity of the cement of needs input according to These parameters.
