Summary of the invention
The present invention will provide that the shield structure passes through the bad ground construction method under a kind of super dark earthing.
For achieving the above object, the technical solution used in the present invention is: a kind of super dark earthing shield structure passes through complicated soil layer job practices, and concrete steps are as follows:
1) soil pressure of shield structure head is set
According to the upper soft lower hard bad ground of the shield machine front soil body, set shield structure head earth balance pressure power;
2) shield machine front soil improvement
When the shield structure passes through hardpan and artesian aquifer, take the householder method improvement shield machine front soil body, be convenient to correctly set up shield machine earth balance pressure power;
3) TBM's position control
When shield machine is constructed in hard-soft heterogeneous ground, shield attitude is controlled, be used for preventing cracked, the misalignment of axe in section of jurisdiction of shield machine;
4) shield tail synchronous grouting control
When shield machine was constructed in sandy soil layer, control synchronous grouting amount sank to causing shield attitude to worsen for preventing that the synchronous grouting quantity not sufficient from causing after the shield tail is deviate from earth's surface posterior settlement and section of jurisdiction.
Shield machine front soil improvement.
The concrete establishing method that the soil pressure of shield structure head is set:
Utilize portal crane that trunkful weight and the empty van weight of every bucket mud are weighed, calculate the actual weight of being unearthed of every propelling one ring, and the side's of being converted into amount, actual amount and the soil pressure of being unearthed of every ring obtained; Perhaps record the actual revolution of screw machine of the every propelling of shield machine one ring and compare, infer that each ring is unearthed to measure and soil pressure; Perhaps calculate theoretical soil pressure according to the geologic report situation.
The concrete grammar of shield machine front soil improvement:
1) hardpan adopts cutterhead to add the water mode to improve:
1. seek and add the water balance point under the different fltting speeds, guarantee the screw machine continuous excavation;
2. cutterhead should keep continuing to add water, avoids forming in the native storehouse interlayer;
2) artesian aquifer adopts the modes such as filling foaming agent and polymer to carry out soil improvement.
The TBM's position control concrete grammar:
1. lower the shield machine gross thrust: use the cutter of backbreaking, shield shell to touch wall antifriction slip casting, use the foaming agent improvement front soil body;
2. slip casting hoop: the section of jurisdiction of holding out the shield tail;
3. adopt the paster material of cork.
The invention has the beneficial effects as follows:
The characteristics of driving, sharp radius curve section driving in job practices integrating tunnel super large buried depth of the present invention, saturated sand and the artesian aquifer, for the construction technology of shield-tunneling construction equipment to shield tunnel in compliance, saturated sand and the artesian aquifer of super large buried depth, saturated sand and artesian aquifer, solve the construction technology difficult problem in small curve tunnel under the disadvantageous geologic condition, formed the job practices of a cover for conditions of similarity.
Job practices of the present invention can solve in many bad grounds difficult point and problem in the shield-tunneling construction, form super dark shield tunnel tunneling construction process, construction technology in the ripe sandy soil artesian aquifer, for underground space development from now on lays the first stone to Deep Development, solve shield structure engineering in the limitation of underground installation than multizone, ensured the sustainable development of Tunnel Boring construction of tunnel exploitation and the popularity of application.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
The construction technology that the present invention passes through bad ground at the super dark earthing shield structure of No. 12 lines of Shanghai Rail Transit 26 mark engineerings, the tunnel that construct, concrete working measure is:
1) soil pressure of shield structure head is set
The soil pressure establishing method:
1. utilize portal crane that trunkful weight and the empty van weight of every bucket mud are weighed, calculate the actual weight of being unearthed of every propelling one ring, and the side's of being converted into amount, obtain actual amount and the soil pressure of being unearthed of every ring, compare with the theory amount of being unearthed.
2. record the actual revolution of screw machine of the every propelling of shield machine one ring and compare, infer each ring be unearthed measure and soil pressure whether reasonable.
3. according to geologic report situation theory of computation soil pressure.
2) shield machine front soil improvement
The 6. layer hardpan adopt a cutterhead to add the water mode to improve:
1. seek and add the water balance point under the different fltting speeds, guarantee the screw machine continuous excavation;
