Embodiment Construction

[0018] Such as figure 1 As shown, a steel base grouting construction method includes the following steps:

[0019] Step 1: Chisel away the concrete around the pre-embedded steel structure base 1 and remove the chiseled loose concrete, remove the laitance, and blow off the dust accumulation under the steel structure base 1 with a fan;

[0020] Step 2: bury the grouting pipe 2 and the overflow pipe 3 between the steel structure base 1 and the concrete base 4 with plugging Wang cement 5, and seal the edges around the steel structure base 1 with quick-drying cement, and the overflow The height of the pipe 3 is higher than the upper surface of the steel base 1;

[0021] Step 3: Carry out a ventilation test, the intake of the grouting pipe 2 and the outlet of the overflow pipe 3, to ensure that there is no air leakage in other parts except the grouting pipe 2 and the overflow pipe 3;

[0022] Step 4: Configure grouting materials and perform grouting, and stop grouting when the ove...

Abstract

The invention provides a grouting construction method for a steel-structured base. The method comprises the following steps of: 1, chiseling concrete at the periphery of an embedded steel-structured base, cleaning the chiseled loosened concrete, cleaning laitance, and blowing off accumulated dust below the steel-structured base by using a fan; 2, embedding a grouting pipe and an overflow pipe between the steel-structured base and a concrete foundation by using strong plugging cement, and sealing edges at the periphery of the steel-structured base by using rapid-hardening cement, wherein the overflow pipe is higher than the upper surface of the steel-structured base; 3, performing ventilation test, sucking air by using the grouting pipe and exhausting the air by using the overflow pipe to ensure that the air cannot be leaked from the grouting pipe, the overflow pipe and other parts; 4, allocating a grouting material, grouting, and stopping grouting until dense slurry flows out of the overflow pipe; and 5, maintaining under the condition that the height of the overflow pipe is kept unchanged after the grouting is finished, wherein the liquid level of grout in the overflow pipe is gradually reduced due to the air shrinkage performance of the grout, and backflow grout can be grouted densely. By the method, the poured grout is dense and has high intensity and high durability without formwork supporting.

Description

technical field [0001] The invention relates to the construction field, in particular to a grouting construction method for a steel structure base. Background technique [0002] In order to ensure the firm connection between the steel structure base and the concrete foundation, fine stone concrete is usually laid at the corresponding position under the steel structure base, and then steel components are installed on it, or grout leakage and slurry leakage may occur during the usual grouting process Phenomena such as water settlement affect the strength and expansibility of the slurry. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a grouting construction method for a steel structure base, the grout is dense, high in strength and good in durability after grouting. [0004] In order to solve the above-mentioned existing technical problems, the present invention adopts the following scheme: a method for grouting a...
