Abstract

A method for reserving construction joints of a rubble retaining wall in building construction comprises the steps of prefabricating waist-shaped rubble blocks (5) for later use, and building the rubble retaining wall (1) from the bottom; when the rubble retaining wall is built and the adjacent construction joint (4) is built firstly, the lower half section below the girdling position of the wedge-shaped rubble retaining wall and the building block of the rubble retaining wall are built into a whole in a staggered mode, and the upper half part of the girdling-shaped rubble building block extends upwards; fully paving a first layer of mortar (3-1) at the construction joint position; and during continuous construction, fully paving a second layer of mortar (3-2) on the first layer of mortar again, then building the rear rubble retaining wall (2) after construction, and alternately building the upper half part of the waist-shaped rubble building block and the rear rubble retaining wall into a whole. The invention effectively enhances the bonding force of the firstly-built rubble retaining wall and the secondly-built rubble retaining wall, and obviously enhances the retaining capacity of the rubble retaining wall.

Description

Setting method for construction joint of rubble retaining wall in building construction

Technical Field

The invention belongs to the technical field of building masonry structure construction, and particularly relates to a setting method of a rubble retaining wall construction joint.

Background

In the building construction, when the rubble retaining wall is built, all construction contents cannot be completed in the same day, so that construction joints are required to be reserved in the same day. The method for setting up the construction joints in the prior art comprises the steps of completely laying the top stones laid last the same day, fully laying cement mortar for rough leveling, fully laying cement mortar again on the cement mortar fully laid the previous day during construction the next day, and then building the rubble retaining wall on the upper layer. The construction joint left by the method is relatively flat, and when the construction joint is flat, the soil retaining performance of the rubble retaining wall is not facilitated, and the soil pressure resistance of the rubble retaining wall is reduced.

Disclosure of Invention

The invention aims to solve the defects of the prior art and provides a method for reserving construction joints of a rubble retaining wall, which is used for enhancing the retaining performance of the rubble retaining wall, enhancing the tensile force between the first rubble retaining wall and the second rubble retaining wall, reducing the risk of overturning the rubble retaining wall and fully exerting the function of the rubble retaining wall.

The purpose of the invention is realized by the following technical scheme:

the method for reserving the construction joint of the rubble retaining wall in the building construction comprises the following steps:

a. pre-manufacturing a waist-shaped rubble building block for later use;

b. building a rubble retaining wall from the bottom;

c. when the rubble retaining wall is built and the adjacent construction joint is built firstly, the lower half section below the girdling position of the wedge-shaped rubble blocks and the blocks of the rubble retaining wall are built into a whole in a staggered mode, and the upper half parts of the girdling-shaped rubble blocks extend upwards;

d. fully paving a first layer of mortar at the position of the construction joint, and roughly leveling the first layer of mortar;

e. and fully laying a second layer of mortar on the first layer of mortar fully laid before the construction joint at the top of the retaining wall, then building the rear rubble retaining wall after construction, and alternately building the upper half part extending out of the waist-shaped rubble building block and the rear rubble retaining wall into a whole.

Further, the top construction joint of the firstly-laid rubble retaining wall inclines downwards towards one side of the earthwork.

Furthermore, the beam waist-shaped rubble building blocks are made of rubbles or are prefabricated by concrete.

Further, the thickness of the waist-shaped rubble building block is consistent with the particle size of the rubble of the retaining wall.

According to the invention, the wedge-shaped rubble blocks are prefabricated, and the later-laid rubble retaining wall and the first-laid rubble retaining wall are respectively tied from top to bottom, so that the construction joint becomes an uneven toothed construction joint, the tie force of the first-laid rubble retaining wall and the later-laid rubble retaining wall is obviously enhanced, the overall structural strength of the rubble retaining wall is enhanced, the retaining capability of the rubble retaining wall is greatly enhanced, and the function of the retaining wall is fully exerted.

Detailed Description

The method for reserving the construction joint of the rubble retaining wall in the building construction comprises the following steps as shown in figure 1:

a. the waist-shaped rubble building blocks 5 are manufactured in advance and placed beside a construction working face for later use. The waist-shaped rubble blocks 5 are made of rubbles for building retaining walls or are prefabricated by concrete; the thickness of the waist-shaped rubble blocks is consistent with that of the rubble retaining wall to be built, the front and back of the waist-shaped rubble blocks are not necessarily required to be very flat, and the waist-shaped rubble blocks are matched with the built rubble retaining wall;

b. building a rubble retaining wall 1 from the bottom;

c. when the first rubble retaining wall 2 built in the first day is built to be close to the construction joint 4, the lower half section below the girdling position of the wedge-shaped rubble blocks 5 and the blocks of the first rubble retaining wall 1 are built into a whole in a staggered mode, and the upper half parts of the girdling-shaped rubble blocks 5 extend upwards and are similar to the extending tooth claws. The top construction joint 4 of the firstly-built rubble retaining wall 1 is inclined downwards towards one side (A side) of the earth to increase the force of the rubble retaining wall for resisting the earth;

d. fully paving a first layer of mortar 3-1 at the position of the construction joint, and roughly leveling the first layer of mortar 3-1;

e. and when construction is continued on the next day, fully laying a second layer of mortar 3-2 on the first layer of mortar 3-1 fully laid before the position of the construction joint 4 at the top of the retaining wall again, then building the rear rubble retaining wall 2, and alternately building the upper half part extending out of the waist-shaped rubble block 5 and the rear rubble retaining wall 2 into a whole.
