Description
Technical Field
The invention relates to the field of buildings, in particular to a waterproof method for a prefabricated manure groove plate seam.
Background
With the rapid development of animal husbandry, the pig industry has been developing from traditional small-scale open-air livestock farming to large-scale industrial farming. The pig house is also transiting from small-scale open-air livestock farms to large-scale modern fabricated pig houses, and is a multi-high-rise pig house.
The manure pit is an important component of the pigsty, and the conventional manure pit is generally a brick manure pit or a cast-in-place concrete manure pit. The brick-built manure pit uses a traditional brick-built structure to realize the structural form of the manure pit. The side plate of the brick-laid manure trough has large thickness and low bearing capacity, and is easy to crack and leak; the field construction operation is more, the pollution is serious, and the construction efficiency is low. The cast-in-place concrete dung trough is obtained by respectively erecting a formwork on the bottom plate and the side plate. The traditional cast-in-place concrete septic tank needs on-site formwork erecting, formwork removing and concrete pouring, and has the disadvantages of multiple construction operations, complex and various working procedures, long construction period and serious pollution; the joints of the side plates and the floor slab form construction joints, and leakage is easy to occur.
With the increasing scale of pig industry and the assembly development of pig houses, the existing brick manure groove or cast-in-place concrete manure groove cannot adapt to the modern pig houses. The prefabricated assembled excrement tank can solve the shortcoming of traditional brick excrement tank or cast-in-place concrete excrement tank to a certain extent, and a plurality of excrement tank units prefabricated by the mill are transported to the site operation, and a plurality of excrement tank units are assembled and spliced to obtain whole prefabricated excrement tank.
The joint plate seam between two adjacent excrement groove units of the prefabricated excrement groove needs to be sealed and waterproof, and two general waterproof methods are available. One method is as follows: and (3) mounting the prefabricated excrement tank units in place, erecting a formwork at a plate joint of two adjacent excrement tank units, grouting or fine aggregate concrete, removing the formwork and maintaining. When the prefabricated manure groove bears load or temperature changes in working, plate seams are easy to crack, leakage is caused, and the durability is poor. The other method comprises the following steps: and (3) mounting the prefabricated excrement tank units in place, filling PE rods at proper positions on two sides of a plate seam of two adjacent excrement tank units, and filling sealant. The method has poor durability of the sealant and is easy to age, thereby causing leakage.
Disclosure of Invention
The invention provides a waterproof method for a plate joint of a prefabricated excrement groove.
The technical scheme provided by the invention is as follows:
a method for waterproofing a slab joint of a precast manure trough, the precast manure trough comprising a plurality of precast concrete manure trough units, a support beam, a manure leaking plate and a walkway plate, which are precast by a factory, wherein: the method comprises the following steps:
s1: mounting and positioning the support beam;
s2: hoisting the precast concrete dung trough units in place and fixing the precast concrete dung trough units on the support beam, and reserving a plate seam with a certain width between every two adjacent precast concrete dung trough units;
s3: paving a dung leaking plate and a walkway plate on the precast concrete dung trough unit, and applying downward load on the dung leaking plate and the walkway plate;
s4: erecting a template at the plate joint, and filling a micro-expansion filler into the plate joint;
s5: and after the micro-expansion filler is cured to reach the set strength, the template is dismantled and the load is unloaded.
Furthermore, the size of the load is 1.05P, and P is the load borne by the prefabricated manure groove during normal operation.
Furthermore, the micro-expansion filler is micro-expansion fine aggregate concrete or micro-expansion high-strength cement paste.
Further, the width of the plate seam is 20-30 mm.
Furthermore, a key groove is reserved at the joint of the precast concrete excrement tank unit.
Further, the load is applied by loading blocks placed on the dung leaking plate and the walkway plate.
Further, the formwork is provided on the bottom plate and the side plate of the precast concrete manure pit unit.
The invention has the following beneficial effects:
according to the invention, a certain downward load is applied before plate seam treatment, the plate seam can deform under the action of the load, then the micro-expansion filler is filled, and finally the plate seam is unloaded, and then when the prefabricated excrement tank bears the actual load, the plate seam material is in a compressed state, is not easy to crack, and has good waterproof performance.

fig. 2 is a schematic diagram of a plate seam structure.
Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The embodiment of the present invention provides a method for waterproofing a slab joint of a precast manure trough, as shown in fig. 1 and 2, the precast manure trough comprises a plurality of precast concrete manure trough units 100, supporting beams 200, manure leaking plates 300 and walkway plates 400, which are precast by a factory, wherein: the method comprises the following steps:
s1: the support beam 200 is installed in place.
S2: and hoisting the precast concrete dung trough units in place and fixing the precast concrete dung trough units on the support beam, and reserving a plate seam 500 with a certain width between every two adjacent precast concrete dung trough units.
Before the precast concrete excrement tank unit is hoisted, the joint of the precast concrete excrement tank unit needs to be cleaned at first.
S3: and laying the dung leaking plate and the walkway plate on the precast concrete dung trough unit, and applying downward load on the dung leaking plate and the walkway plate.
The dung leaking plate and the walkway plate can be of an integral structure or a split structure.
S4: and supporting a template at the plate seam, and pouring a micro-expansion filler 700 into the plate seam.
S5: when the micro-expansion filler is cured to reach the set strength, the template is removed and the load is unloaded.
In order to solve the problem of easy cracking in the traditional plate seam processing method, a certain downward load is applied before plate seam processing, the plate seam can deform under the action of the load, then the micro-expansion filler is filled, and finally the plate seam is unloaded, and then when the prefabricated excrement tank bears the actual load, the plate seam material is in a pressed state, is not easy to crack and has good waterproof performance.
