Abstract
The invention relates to a method for constructing a built-in foundation bolt regulating hole of an equipment foundation, which comprises the step of: firstly, embedding a built-in foundation bolt of the equipment foundation to a preset position where concrete is poured, and also comprises the steps of: 1, wrapping two semicircle polystyrene foam tubes on the outer wall of the built-in foundation bolt of the equipment foundation, wherein the top elevation of the polystyrene foam tubes is equal to the top elevation of poured concrete, and the bottom elevation of the polystyrene foam tubes is 300-400mm lower than the top elevation of the poured concrete; 2, binding the outer parts of the polystyrene foam tubes with iron wires for fixing before the concrete is poured, pouring the concrete; and 3, after the concrete poured at the outer parts of the two semicircle polystyrene foam tubes in the step 2 is strengthened, melting the polystyrene foam tubes with gasoline and forming the built-in foundation bolt regulating hole. The method has the advantages of being simple and easy to operate, effectively improving the construction quality, shortening the construction time, improving the construction efficiency, and being high in operation safety and accuracy.
Description
Technical field
The invention belongs to the realm of building construction, especially a kind of Equipment Foundations direct-burried stone bolt is adjusted the job practices in hole.
Background technology
Along with expanding economy, the infrastructure construction of steel industry is increasing, in the construction of the infrastructure of steel industry, its civil works part is mainly based on Equipment Foundations, the most of direct-burried stone bolt that adopts of Equipment Foundations in design, the installation accuracy of direct-burried stone bolt directly has influence on next process unit and installs, and therefore, the installation accuracy of stone bolt is particularly important in the construction.The Equipment Foundations direct-burried stone bolt center displacement allowable variation that national regulation requires to have constructed is ± 2mm, because the installation accuracy height of Equipment Foundations direct-burried stone bolt, difficulty of construction is big, the Equipment Foundations direct-burried stone bolt of having constructed does not often reach the national regulation requirement, need Equipment Foundations direct-burried stone bolt is carried out the secondary adjustment, promptly Equipment Foundations direct-burried stone bolt is adjusted the hole and construct, traditional job practices has two kinds at present: 1, manually cut a hole concrete forming device basis direct-burried stone bolt and adjust the hole; 2, adopt the prefabricated direct-buried stone bolt of cement perlite to adjust the hole; Above-mentioned two kinds of methods are carried out construction that Equipment Foundations direct-burried stone bolt adjusts the hole, and there are the following problems: (1), manually cut a hole concrete and waste time and energy, prolonged the engineering time, reduced efficiency of construction; (2), cement perlite intensity is low, cracky, complex process, concrete pours and is difficult to take out.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the job practices that provides a kind of Equipment Foundations direct-burried stone bolt to adjust the hole, this method construction precision height, operation is simple, effectively improve construction quality, shorten the engineering time, improve efficiency of construction, processing safety height.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of Equipment Foundations direct-burried stone bolt is adjusted the job practices in hole, at first Equipment Foundations direct-burried stone bolt is buried underground the precalculated position of pour concrete, and it also comprises the steps:
(1) the polystyrene foam pipe of two semicircles is wrapped in the outer wall of Equipment Foundations direct-burried stone bolt, polystyrene foam pipe top absolute altitude is identical with pour concrete top absolute altitude, and polystyrene foam pipe bottom absolute altitude is than the low 300～400mm of pour concrete top absolute altitude;
(2) pour concrete after fixedly finishing is fixed in the polystyrene foam pipe outside of two semicircles with the iron wire colligation before pour concrete;
(3) treat on the outside pour concrete of polystyrene foam pipe of two semicircles in the step (2) with gasoline the polystyrene foam pipe to be dissolved after the intensity, form the direct-burried stone bolt and adjust the hole.
And the polystyrene foam bore of described two semicircles equals the external diameter of Equipment Foundations direct-burried stone bolt.
And the polystyrene foam pipe of described two semicircles adopts the iron wire colligation to fix.
Advantage of the present invention and beneficial effect are:
1, the job practices in these Equipment Foundations direct-burried stone bolt adjustment hole adopts the polystyrene foam pipe of two semicircles as the mould of adjusting the hole, after casting and constructing is finished, only need the polystyrene foam pipe be dissolved with gasoline, easy for installation, need not dismounting work, save the engineering time, improved efficiency of construction, and construction quality.
2, the polystyrene foam pipe adopts the iron wire colligation to fix in the job practices in these Equipment Foundations direct-burried stone bolt adjustment hole, and after the polystyrene foam pipe dissolved, the iron wire of colligation can reuse, economical with materials.
3, operation is simple, effectively improve construction quality, shorten the engineering time, improve efficiency of construction, processing safety height in the present invention, is the job practices that the high Equipment Foundations direct-burried stone bolt of a kind of precision is adjusted the hole.

Fig. 2 is the structural representation after the polystyrene foam pipe of two semicircles of the present invention dissolves.
The specific embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of Equipment Foundations direct-burried stone bolt is adjusted the job practices in hole, at first carries out the concrete construction of Equipment Foundations, in the process of construction Equipment Foundations direct-burried stone bolt 3 is buried underground on the precalculated position of pour concrete 1, wherein also comprises the steps:
(1) the polystyrene foam pipe 2 of two semicircles is wrapped in the outside of Equipment Foundations direct-burried stone bolt, the polystyrene foam bore of two semicircles equals the external diameter of Equipment Foundations direct-burried stone bolt, polystyrene foam pipe top absolute altitude is identical with pour concrete top absolute altitude, polystyrene foam pipe bottom absolute altitude is than the low 300～400mm of pour concrete top absolute altitude, and the polystyrene foam pipe of present embodiment bottom absolute altitude is than the low 400mm of pour concrete top absolute altitude;
(2) the polystyrene foam pipe outside of two semicircles is fixed with iron wire 4 colligations before pour concrete after, also can adopt bonding mode that the polystyrene foam pipe of two semicircles is fixed, adopt iron wire colligation mode shown in the present embodiment accompanying drawing, pour concrete after fixedly finishing;
(3) treat on the outside pour concrete of polystyrene foam pipe of two semicircles in the step (2) with gasoline the polystyrene foam pipe to be dissolved after the intensity, form the direct-burried stone bolt and adjust hole 5, the iron wire that colligation is used can directly take out from adjust the hole, recycles.
