Abstract
The invention relates to the technical field of foundation pit protection, in particular to a screw-in type steel pile supporting method, which comprises the following steps: cutting grooves with the width of 500mm near two sides of a position to be cleared, and arranging a dewatering well outside the grooves, wherein the depth of the dewatering well is greater than that of the thread support piles; secondly, putting U-shaped steel into the groove, wherein through holes are formed in the U-shaped steel at intervals; inserting the thread support pile into a through hole in the U-shaped steel and screwing the thread support pile into the ground; step four, removing soil between the two grooves; step five, feeding municipal pipelines; step six, backfilling and screwing out the thread support pile; and seventhly, reciprocating the steps from the first step to the sixth step forwards along the ground until the construction is finished. This device will take screwed fender pile to twist the underground and play the effect of strutting, can also twist out after strutting the completion and reuse, and the noise is little in the work progress, can not destroy building on every side, and is also very little to building on every side.
Description
Technical Field
The invention relates to the technical field of building construction, in particular to a screw-in type steel pile supporting method.
Background
At present, in the process of municipal pipeline construction, the foundation pit is supported around in order to protect the safety of the foundation pit, the current situation of the country shows that the steel yield is rich, the price is low, the stock is large, the country encourages various industries to go to the stock, the country requires that the opportunity is grasped, the foundation pit is supported and the section steel is fully utilized to replace a reinforced concrete pile, the construction method not only conforms to the situation of the country and can generate good economic and social benefits, but also has good environmental protection benefits because the section steel pile can be recycled and reused, the pile is not left underground after the foundation pit is supported and supported. But need drive into the steel sheet in the underground construction process and can produce very big noise in municipal administration work progress, cause noise pollution.
Disclosure of Invention
The invention aims to overcome the defects of the technology and provide a screw-in type steel pile supporting method.
In order to achieve the purpose, the invention adopts the following technical scheme: a screw-in type steel pile supporting method is characterized in that: the method comprises the following steps: cutting grooves with the width of 500mm near two sides of a position to be cleared, and arranging a dewatering well outside the grooves, wherein the depth of the dewatering well is greater than that of the thread support piles; secondly, putting U-shaped steel into the groove, wherein through holes are formed in the U-shaped steel at intervals; inserting the thread support pile into a through hole in the U-shaped steel and screwing the thread support pile into the ground; step four, removing soil between the two grooves; step five, feeding municipal pipelines; step six, backfilling and screwing out the thread support pile; and seventhly, reciprocating the steps from the first step to the sixth step forwards along the ground until the construction is finished.
Preferably, in the fourth step, after the soil is removed, the transverse supports are arranged on the inner sides of the thread support piles.
Compared with the prior art, the device has the advantages that the support pile with the threads is screwed underground to play a role in supporting, the support pile can be screwed out for reuse after supporting is completed, the noise is low in the construction process, surrounding buildings cannot be damaged, and the influence on the surrounding buildings is very small.

FIG. 2 is a side view of the present invention;
fig. 3 is a side view of steps four and five of the present invention.
Detailed Description
The following detailed description of the preferred embodiments will be made with reference to the accompanying drawings. As shown in fig. 1-3, a screw-in type steel pile supporting method comprises the following steps: cutting grooves 2 with the width of 500mm near two sides of a position 1 to be cleared, and arranging dewatering wells 3 on the outer sides of the grooves, wherein the depth of the dewatering wells is greater than that of the thread support piles; secondly, putting U-shaped steel 4 into the groove, wherein through holes are formed in the U-shaped steel at intervals; inserting the thread support pile 5 into a through hole in the U-shaped steel, screwing the thread support pile into the ground, wherein the surface of the thread support pile is provided with threads, and the thread support pile can penetrate through the through hole and be screwed into the ground through a drilling machine to play a protection role side by side; step four, after the two rows of screwed threaded support piles are screwed, removing soil between the two grooves; step five, a municipal pipeline 6 is put into the place where the soil is removed; step six, backfilling and screwing out the thread support pile; and seventhly, reciprocating the steps from the first step to the sixth step forwards along the ground until the construction is finished.
In order to ensure the construction safety, in the fourth step, after soil is removed, the inner side of the thread support pile is provided with a transverse support 7. The U-shaped steel on the two sides is supported by the transverse supports, so that the inward collapse of the mud is prevented in the process of removing the mud.
This device will take screwed fender pile to twist the underground and play the effect of strutting, can also twist out after strutting the completion and reuse, and the noise is little in the work progress, can not destroy building on every side, and is also very little to building on every side.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
Claims (2)
1. A screw-in type steel pile supporting method is characterized in that: the method comprises the following steps: cutting grooves with the width of 500mm near two sides of a position to be cleared, and arranging a dewatering well outside the grooves, wherein the depth of the dewatering well is greater than that of the thread support piles; secondly, putting U-shaped steel into the groove, wherein through holes are formed in the U-shaped steel at intervals; inserting the thread support pile into a through hole in the U-shaped steel and screwing the thread support pile into the ground; step four, removing soil between the two grooves; step five, feeding municipal pipelines; step six, backfilling and screwing out the thread support pile; and seventhly, reciprocating the steps from the first step to the sixth step forwards along the ground until the construction is finished.
